Abstract:
Having completed a successful Model Energy Home [66] project for the London Borough
of Sutton I wished to undertake a research project into Low Energy within a domestic
setting at the start of my MA programme, in September 1998. Research into low energy
housing and its constituent parts has helped my approach the problem from a different
perspective. Linking these various individual items became the target. The movement
of air and the reaction of each part of the house with it became that link. Occupants
perceive the ambient temperature of the house by contact with the air within it. Wall,
floor, roof, and window effectiveness is measured by the degree to which the air
temperature on either side of the respective item is affected. The heat transmitted
through each item governs its energy rating Which is measured by the rise in air
temperature. Air again plays a key factor in contaminated particulate transmission with
respect to health issues. Air is the link therefore to my energy efficient house design.
The project design solution proposed at puts forward one possible solution to the low
energy healthy living debate. I have shown through my research reasons why the
building should be produced as a holistic design, avoiding single faceted solutions to
solve complex problems. The design has movement and openness. Both of these are
essential to my project brief. Having produced four design proposals, the final one is the
design which satisfies both the core requirements and aesthetic aspects of the design.
I am satisfied that this solution can be built and that it will deliver energy savings whilst
providing a healthy environment in which to live. Furthermore This proposal should
provide a starting point for the next phase, that of a doctoral research project.
Acknowledgements
I should like to thank all those who have contributed in no small part to the success of
this paper. In particular I would like to pay tribute to the tireless efforts of the staff of
the MA programme and in particular the Head of MA, Francine Norris for her unceasing
help and encouragement. I am also indebted to Colin Perrott for his lecture “ Computing
creativity in design” along with Professor Peter Robertson's lecture “the future of design
in design education”, both part of the MA core lecture series at KIAD Rochester in
1998.
I should also like to thank Professors Porter and Norford for their help and assistance
during my research visit to the Massachusetts Institute of Technology (MIT). A special
thanks is due to Professor Norford who supplied me with unpublished research on his
projects in Beijing. The MIT visit would not have been possible without the help and
assistance of Tevfik Bacioglu and his contacts within MIT. These contacts provided me
with the initial invitation to the university and the opportunity to participate in a
seminar and tutorials with Professors Porter and Norford.
Although I have viewed some aspects of the Erie-Ellington project unfavourably, the
Green Village Company comprising the architects and builders behind the project have
given me a great deal of help. Without their open minded approach, this project would
not have been possible .To them and for their presentation at MIT in November 1999
I warmly thank them.
There are several other fellow students from my first year who helped and encouraged
me considerably and to Nada & Abdullah Saudi in particular I would like to express my
thanks. To my girlfriend, Shelagh Moore, who has been such a support to me over this
last year and without whose help I would not have been able to complete the
programme. My family for assisting me in research during the first half of the course
and two friends in particular, Colin Perrott and Harold Robinson who have throughout
the two years of my course given me unstinting support and encouragement and have
never allowed me to lose sight of my objective. To all those who helped me with the
interdisciplinary project. I am unable to name them due to the need to respect their
confidentiality and anonymity. Without their help this part of the project would not have
been possible. There are many others who have helped me through the 2 years of the
programme and a special thank you should be extended to Ruddy Austin, Architect, for
his help, guidance and tuition which enabled me to reach required level for admission
to the MA programme, having not previously undertaken a BA degree course.
Additionally I would like to acknowledge all the many contacts within the Engineering
and Production-prototyping industries. Over the years they have helped me in gaining
first hand knowledge and understanding in the fields of production and CAD-CAM
engineering.
Richard Handyside’s advice on sustainable environmentally friendly products was
invaluable.
To all of the above I should like to extend my warmest thanks.

0.1 Introduction :
This paper has been produced as part of my Master of Arts project report and should
be read in conjunction with the MA show held at KIAD in September 2000.
Sustainability is not a simple subject. I have therefore been able to only scratch the
surface of this subject. Low energy naturally ventilated housing combined with
“healthy holistic” living is the main thrust of my project proposal. The first three
chapters show a progressive development of my understanding of the subject, and an
introduction to the complex interrelationship between technological solutions and their
impact on the environment. There is a need to highlight the true cost to human health
of single track solutions. Research into this subject has been outlined within the first
three chapters. chapters fourth, five, & 6 documents the design project required by the
N. J. K.-W. MA Dissertation Introduction Pg. 6
MA programme. My research has been aided by the use of a
N. J. K.-W. MA Dissertation Introduction Pg. 7
qualitative analytical programme Nud*ist N4. This has enabled me to collate both
logical argument and source materials efficiently thus allowing me to cover the subject
in greater depth in preparation for my doctoral studies. This paper therefore should be
read in part as an application to carry the research forward at doctoral level. This
project is by no means over...This is just the beginning.
The purpose of this MA proposal is to determine if a design could be developed which
was comparable in energy performance to the Erie-Ellington development in a suburb
of Boston Massachusetts USA. The Erie - Ellington project is spearheading the Low
energy sustainable architecture “Build America programme”. However unlike this
development, I would like to make use of natural or passive stack ventilation. The
reasons for this will become clear as this paper unfolds.
It has been demonstrated that the Victorians used the principle of air flow through a
building using chimneys as vent stacks thus adequately ventilating their buildings. This
system has been replicated partially by the Berkeley Homes development in London
Rd ,Westerham, Kent.
I began with the premise that air movement may be enhanced by the way the entire
building is shaped. Similarly an aircraft is not just dependent on it’s wing design for
flight but upon the design of the entire fuselage. I believe that the interruption of air
flow by a building can be utilised effectively in the inner space. Through careful
placement of vent louvres and ducting in appropriate places, both on the roof and on
the building facade. I contend that external air movement can be harnessed to create
healthy internal environments.
Through careful space planning and opening up of the wall spaces within the building
I can further enhance the air flow movement throughout the entire envelope. This I
suggest will eliminate or at least drastically reduce the need for mechanical ventilation.
The only aspect of mechanical ventilation that should then be warranted would be
extraction fans for bathroom and kitchen areas where additional forced extraction
would become necessary due to the build up of steam. Whilst the Americans favour
mechanical ventilation partly for the heat recovery potentials such systems offer,
N. J. K.-W. MA Dissertation Introduction Pg. 8
research programmes in Europe are now investigating Passive stack ventilation (PSV)
and the possibility of recovering up to 70% of this energy whilst maintaining the use
of PSV systems.[1] The overzealous use of filtered air conditioning, which I shall
demonstrate, has potentially disastrous and hitherto hidden health costs.[2] The
“American approach” to energy efficiency is being taken up by architects in Europe.
I think that this will lead to higher health bills as sick building syndrome increases
exponentially to the use of filtered mechanical ventilation.
My research began with the six issues that I wished to raise for my first project. I
chose these as the environment, the greenhouse effect, sustainability, pollution, market
forces and the over-use of our energy resources. Further to this my research progressed
in depth into various fields including health education, computerisation and Feng Shui
amongst others. In looking at air quality I have discovered important research
suggesting alternative solutions for the improvement of air quality within the internal
environment.
My interest in the Feng Shui approach is related to the fundamental issue of holistic
living advocated by the original Chinese practisers of the art of Feng Shui rather than
the more fashionable and single solution approach popular today. I believe the answer
to environmental issues lies more in a holistic approach to the problem rather than the
addressing of a single issue at a time with little heed of the consequences of the
potential outcome. The way forward is, I believe in a multiplicity of solutions.
In this MA paper I have set out a researched argument that I wish develop further at
doctoral level, for this approach. Many solutions which have been put forward in the
past have merit and should not be dismissed out of hand. This would be tantamount
to throwing the baby out with the bathwater. I have criticised the Erie Ellington project
for it’s over dependence on mechanical ventilation but it does have merit. They have
relied to a great extent on the air conditioning system to provide the energy values
required in the whole house. However I am very much in favour of the ethos which
they have presented for sustainable development. Had a ventilation system been
chosen which was based more on assisted exhaust system or passive stack system, I
feel that a better result would have been achieved due to the low energy inputs that
N. J. K.-W. MA Dissertation Introduction Pg. 9
such a system would require. I do acknowledge however that the climate in North
America is far more extreme than that in Europe and therefore the need for additional
cooling and ventilation is far greater than would ever be found in this country .
Empirical wisdom should not be dismissed. Vitruvius, in 110 BC writing about the
effects of heat loading on buildings proposed that shade and the properties of
reflectivity of roofing surfaces could reduce heat loading by up to 30%.[3] There are
many solutions to the heating and cooling issue. An over reliance on technology is
therefore not potentially the best way forward. Should a solution be found which did
not rely on continual energy consumption to produce energy savings, this would be
most beneficial in the long run.
I have been fortunate in being in a position to apply this research in my everyday work
. I have recently completed a design proposal for a set of twelve houses in Shamley
Green . This in an internal layer follows a very simple passive stack system. I have
been able to not only put forward a theoretical model and apply many of the principles
which I have developed within this MA research project but to put this into practice
by the opportunity afforded to me when I was requested to present a design proposal
by London and Quadrant Housing Trust for a series of twelve low income houses to
be built in Shamley Green, Surrey. The designs of these houses are now before
planners, and should all go according to schedule, construction should begin in May
2001 with a completion date of December 2001.

Chapter 1: Interdisciplinary approach to Architecture
1.1 Who knows what?
The value of this project was an introduction to working from one discipline with the
tools of another. As such it was explored in depth at the time and in my Post Graduate
Diploma submission. For these reasons, only the conclusion remains in this written
work.
The interdisciplinary project was designed to explore the degree of common
knowledge and understanding of features, terminology and graphical representation of
architectural design by selected groups of people from differing backgrounds and
disciplines.[4]
A group of architects, engineers, students of interior architecture at BA and MA levels,
and the General Public were selected randomly to conduct the sampling. Three
research projects were devised which were further sub - divided into two phases.
Initially the research timetable had only one phase, of two projects. However it

became clear that the original aims for the research project were not being addressed
and an additional second phase was added to address this issue.[5]
1.2 PHASE ONE SUMMARY OF FINDINGS:
At the outset of this project I had the idea of creating a drawing of a room based upon
the results of the initial survey. I had assumed that most people completing the
questionnaire would guess when they were unsure of the answer. However I discovered
that respondents particularly those with a working knowledge of the subject, were
reluctant to participate in a written form. However those that did undergo the trial
performed well.
On the second set of questionnaires This took the form of a sheet of building
component names and blank spaces for those questioned to fill in their definition of the
building components itemised.
1.3 PHASE TWO SUMMARY OF FINDINGS:
Phase two had a 75% participation rate. It must be stressed that for this project street
polling was not considered an option. Due to the time limit and financial resources
required for such a study. Instead a limited cross section of people representing a
typical professional / client setting were selected. This for the purposes of this project
was deemed appropriate. When the first people were questioned regarding the reading

perspective drawing recognition Lableing identification
of the drawings, illustrations and finally viewing the model, the results were as follows:
1.4 LESSONS LEARNED:
The survey participation numbers for all three sections totalled only 26 returns and
therefore was too small a sample to make an accurate statistical analysis. In order to
carry out a truly representative survey much more time would have been required
together with a greater number of participants in order to provide a representative
sample for statistical purposes. However the experience and problems encountered in
conducting such a survey for my personal project has been a valuable learning
experience.
The Interdisciplinary approach to the project was achieved by bringing knowledge,
visual iconic symbology, Technical drawing, and Architectural model-making together.
This was carried out to evaluate this selected group understanding of terminology that
may be used in a first encounter between a client and the building designer.
The language of communication my be common usage English. The meaning of the
N. J. K.-W. MA dissertation Ch. 1 Pg. 13
individual words however is open to a wide margin of interpretation. Therefore there
is a need to clarify the meaning of the words used in order for there to be a precise and
informed dialogue between client and Architect.
Chapter 2: Teaching Technology- Design in Education
2.1 Keeping pace with change
When setting out the vision of design in education for the Carnegie Mellon University
in 1998, Daniel P. Siewiorek [6] stated that;
“Design is the main differentiation between products and processes in the
market place”.
To maintain the commercial competitiveness of a company it is essential that designers
have access to the latest technological design procedures. This reduces the gestation
period of the development and thus gains a competitive advantage. Technology itself
is constantly increasing in effectiveness through computer process speeds; and
therefore programme efficiency. The rate at which these leaps of performances accrue
additionally continues to increase. Thus the effectiveness of a given design team is
irreversibly linked to the performance of the company’s computer effectiveness.
Competitive advantage is the key to market success and skill levels within the design
team of a company are therefore critical to this success.
“Design is the creative process that determines function, form, capacity and,
utility, the utility of a product or process [6]".
Products unable to satisfy the needs of the consumer will fail in the market place. The
design team requires more than computers and technology to produce a product that
is commercially successful. Marketing of a product in order to generate a need for the
item is also key to the success or otherwise of the design team. The interdisciplinary
alliance therefore of marketing, design, research and development is fundamental.
N. J. K.-W. MA dissertation Ch. 2 Pg. 13
Cost of production of the product is a function of effective design through correct use
of materials, production methods, relevant technology, product distribution and
production quantities. Products may be precisely what the target consumer requires but
at a cost that few can afford. The company with the competitive advantage to the
consumer at the right price and at the right time will enjoy the most success.
This then sets out the traditional view of design practice and company’s vie with each
other to produce ever better products for the customer to purchase. Marketing of the
merchandise is aimed at a level so that even the most unimaginative and useless
products are given the “must have” label until a new model comes along. Allegiance
is then transferred to the new product. Where does the company recruit the personnel
needed in order to supply their needs? Are colleges and universities equipped to
provide the requisite training for the number of skilled designers needed. Are they able
to keep pace with the ever increasing leaps in technology? Currently there seem to be
two choices that academic institutions have to make. Keeping up with current best
practice whilst coping with the advances in technology and all the ongoing costs that
such a commitment demands, or teaching design theory and practice without direct
reference to technological enhancements.
Such a choice is however never clear cut. If the academic route taken is based purely
on technology then the ever increasing rate of equipment obsolescence would mean an
ever growing financial strain on the organization; in order to maintain the competitive
edge in the market place. Industry is able to sustain a higher level of ongoing
reinvestment as this revenue generation centre is not reliant on a fixed number of units
producing an ever increasing source of revenue. Cost per unit can be calculated before
the product is released onto the market and break-even production levels will allow for
increases in production costs as well as research, design and development costs. If the
marketing department states that a breakeven point is not sustainable, the product is
either re-evaluated and re-designed or dropped from the production equation
completely. Such changes may be made and implemented in weeks or at worst months.
Academic institutions may be slower to react. They are therefore more vulnerable to
changes in design technology and the implications of those changes on current or
N. J. K.-W. MA dissertation Ch. 2 Pg. 14
future forces. A product may take three months to design and produce and one month
to evaluate in the market before reappraisal and possible re-design. In the space of one
semester the nature of the product and therefore the needs of industry for the skills on
offer by the recently graduated may change so fundamentally, that those who have
spent between one and three years training may find, that the majority of their skill
base is of little or no value to the potential employer. In the field of Computer Aided
Design Draughting one of the market leaders changed its product three times within
the space of three years. Each time change occurred the entire workforce associated
with this product had to be updated in order to maintain a competitive edge. At the end
of this upheaval there was no academic course to be found which could train personnel
on the latest version of the CAD system. All recruits to the company therefore had to
come from other commercial practices in order to seamlessly slot into the production
team without the need for further expensive training programmes. This left new
students applying for a position within the company seriously disadvantaged.
2.2) Teaching Technology; Design in Education
Organisational structures within the commercial or academic environment both require
effective communication routes to other operational areas. The same is true for an
effective design team. Effective solutions with ineffective routes of communication
lead to poor results and frustration to all. “A chain is only as strong as it’s weakest
link.” The same can be said for communication. A reduction in the communication
speed in one part of a system will lower the entire system to that speed. If for example
a new modem is installed into a computer with a communication Baud rate of 98,000
bits per second but the telephone line it is connected to runs at a Baud rate of 42,000
bits per second then this lower rate is the maximum communication speed at which the
system can possibly work if the telephone Baud rate cannot be increased.
Should a factory be setup with a central design and CAD centre with direct links to
CNC machining centres, and the flow of programmes matches the machine’s ability
to produce the product; bottlenecks will not be produced. This results in effective use
of both centres of design and manufacture. If however the capacity in the CNC
department is low, bottlenecks will be created resulting in the need to purchase more
N. J. K.-W. MA dissertation Ch. 2 Pg. 15
machine time. Conversely should the machines work faster than the design team can
produce programmes, the system slackens and ineffective working practices occur as
a result. The same is true of the interdisciplinary relationships within a design team.
Should any part of the design process falls behind in either communication
effectiveness, lack of capital investment or out-dated working practice the end result
is under-achievement. Frequently this under achievement is not identified until rising
prices compared to competitors results in diminishing sales or loss of orders.
2.3 Design theory or Design practice?
In academic centres the need for change when realised; is so costly to implement, that
should funding be refused, the gap between industry and research widens still further.
This results in frustration to the students together with the loss of further teaching
opportunities. Rob A. Rutenbar[7] Professor of CAD Resources, Carnegie Mellon
University suggests,
“ it is difficult for academics to stay close enough to some of the real problems
to make relevant contributions” and he goes on to say that “ unfortunately,
there is now a strong perception on the part of industry that too much academic
work focuses on low-impact problems: meaningless refinements of individual
point tools, or designs in technologies too simple or too small for the critical
effects to occur”.
It is possible that theory rich academic proposals may lead to a divergence of interest
between industry and academia. Rutenbar[7] stated when looking at the future of CAD
research in his own university;
“ many in both industry and academia feel that the research directions of the
field have perhaps turned inward too much...almost always, the blame for this
detachment is lain on the increasing distance between research and practice”.
Rutenbar [7] believed that increasing cost and diversity of technology was one possible
explanation for this. He also felt that there was an “ increasing distance between CAD
N. J. K.-W. MA dissertation Ch. 2 Pg. 16
researchers and designers”[7].
2.4) Massachusetts Institute of Technology visit and Tutorials
“The art of green design is not just what is put into a building, but what is left
out. The nicest systems are those ones you no longer need”.[8]
It is one of those coincidences in life that what you are looking for is not always what
you find, and what you find is often better than you were looking for. So it was, when
I set out to talk to Professor Sibel Bozdogan at the Massachusetts Institute of
Technology, Boston, USA. Unfortunately, the appointment had to be cancelled due to
reasons beyond her control and I was instead given the name of Professor William
Porter. This in turn led to an introduction to Professors Fernandez and Norford. The
tutorials I had with Professors Porter and Norford, were extremely interesting and
introduced me to the philosophy and approach of MIT to design education.
Professor Porter [9] indicated that teaching on the subject of sustainable architecture
was given mainly in year three of the BA Architecture programme at MIT. In his
opinion, this has lead to a divided rather than holistic approach to sustainable
architectural design. Professor Norford on the other hand, fully supported the current
approach and stated that not only did students benefit from the sustainable architecture
tuition only in year three but furthermore suggested that much of the current
sustainable strategy may soon be incorporated within computer software, material
selection, environmental, heating, lighting and fuel consumption issues highlighted as
the design is produced on screen.
It was William Porter's [9] view that too little teaching of computer technology was
given to students at the outset of the course. He predicted that this would resolve itself
as the general level of student computer literacy increased over the following three
years. At the same time computer aided help facilities will require students to become
computer dependant.
N. J. K.-W. MA dissertation Ch. 2 Pg. 17
Les Norford [10] was of the opinion that many of the technical aspects involved in the
design process would be incorporated within computer programmes thus leaving the
written text book in a minor position compared to the situation ten years ago. “Bolt
on” Computer programmes are currently being written for AutoCAD enabling students
to become well versed in all areas of Architecture and structural analysis. He was quite
emphatic that this was the only way forward. The pace of change allied to the need to
progress still further in a given direction could and probably would only be met by
software writers interfacing with technology. When accessed via the Internet this
would give instant access to new programmes at a fraction of the cost of printing
together with the ability to integrate the old and new as far as add-on programming was
concerned. To emphasise this point further he gave me two papers[11]& [12] which he was
to present at a forum in China the following week demonstrating the ability of software
written within the MIT campus to evaluate the needs of the Beijing air-conditioning
with existing and proposed housing stock.
2.5 Key Findings:
Thus far the student’s role in this debate has been a passive one; in that he or she, once
within a university setting has little say in the short term as to how tuition or research
is structured. Their only choice may be made by voting with their feet at the time of
their selection of University when the technological resources available in individual
colleges may influence their decision. If technology continues to advance at the current
rate there is the prospect that the number of universities able to offer the technological
edge and and as a result high quality applied research will diminish at an ever alarming
rate. This will lead to fewer opportunities for post and under graduate study.
There seems a stark choice to be made for academic institutions. Firstly to instruct and
spearhead research in applied technologies thus enabling industrial advancements.
However this might only be successfully achieved by a few leading universities who
command the financial resources required to keep pace with the increasing complexity
of computer technology. Alternatively theory rich non applied teaching and research
methods may be utilised in the hope that results can be taken up and applied in the
industrial sector. Following my visit to MIT in September 1999 I found that there was
a third option which was the subsidisation by industry of the technology required by
N. J. K.-W. MA dissertation Ch. 2 Pg. 18
the universities to produce the calibre of graduate required.
Industry is unlikely to decrease it’s demand for increased power and flexibility in the
field of computer aided technology to allow competitors and academics to catch up.
This will lead to fewer, highly trained, individuals in fewer locations with the ability
to exert a strangle hold on both the academic and industrial sectors and all the power
that is associated with that position. The alternative envisaged by Siewiorek [6] in his
“Our Design process vision” is not much more attractive;
“We envision a time when the end user will interact with a computer-based
design system.”.
This would potentially do away with much of the current debate on applied versus
theory rich research, as designers may at a stroke be made redundant eliminating the
need for costly centres of industry and education. However this would have both a
human and economic cost to society. Is this the future?
What is certain is that visual communication is the key factor in effective design
communication. The ability to communicate visually with or without the aid of
computers is and will remain, fundamental to design education. Those colleges and
universities lacking in computer teaching facilities, and by this I mean a dedicated
computer per student; as found in the leading American universities, will need to work
that much harder to produce the students with the edge that industry will increasingly
demand. Although difficult, this would by no means be impossible as the human mind
has infinitely more potential than technology. One only has to look at history to
identify genius’s in various fields who have overcome the most enormous odds to
create music, literature and inventions which are still marvelled at today. The same is
true of design. Ultimately their has to be a working partnership between the human
mind and technology.
Following my research into design and education, I also additionally questioned, are
books on architectural design now destined to be archived in Historical libraries rather
than becoming vanguards of current practice? It would appear so. Most textbooks are
now obsolete by the time they are published. Les Norford suggested that
N. J. K.-W. MA dissertation Ch. 2 Pg. 19
“as computer help products became more universal within MIT, the need for
reference books will diminish still further”[13]
This put me at a cross roads in my research to date. Insight into the media world with
their need for ever growing sales figures and lower production costs combined with
current thinking within MIT, made it clear to me that the production of a manual with
a high level of visual aids would be both prohibitively expensive and potentially
obsolete by the time it was published.
Investigating computer interfacing directly into software programmes was well beyond
the scope of a single MA programme These final pieces of information enabled me to
realise that within the constraints of the MA programme at KIAD, my investigation
into visual aided text reference manuals for all practical purposes was over and that I
would have to look at another idea to develop further.

Chapter 3: Sustainable Design using Air in Architecture
3.1 Introduction
Sustainable development is the concept of living and developing in ways which ensure
future generations can enjoy the Earth's riches. In other words - living today with
tomorrow in mind [14]. Urban regeneration must address the area of Effective Energy
Consumption if it is to have any long term sustainable future in the U. K. of tomorrow.
The reduction of Energy consumption along with pollution caused by Carbon
Monoxide is now mandated under “Local Agenda 21 [15] following local
implementation of agreements reached at the 1992 United Nations “Earth Summit” in
Rio de Janeiro.
In my post - graduate research paper I compiled examples of past universal practice
in order to put the debate into context, and thereby define the direction of my research
into Effective Energy Consumption and it's effect within the Urban Regeneration
programme. The future depends on the understanding past mistakes and successes, and
the design of an energy efficient sustainable urban environment. [16].
3.2 In The Beginning:
The taking of the famous photograph looking back at earth following American
astronaut Ed White's space walk of 1965 could be argued as a seminal moment in our
evaluation.[17] For the first time man was able to <see' our small planet in the context of
a vast universe.
The Kyoto agreement in 1997 brought green issues to the forefront of the political
agenda. Previously champions of this cause had been Green-peace and fringe elements.
Einstein’s theory of relativity E=MC2 was used to promote government sponsored
television advertisements selling the concept to the public that there was an economic
benefit to energy efficiency. “Energy Efficiency equals more cash to you”.
This brought awareness of the environment and the relative effects down to
individuals. Manufacturers of white goods [18] are now required to display information
N. J. K.-W. MA dissertation Ch. 3 Pg. 20
on their products giving, in most cases consumers an informed choice at the point of
sale. This enables the consumer to understand the meaningful running costs and energy
efficiency of most of the products used.
Thus the value placed upon the environment of the future is demonstrated by how
society lives today.
3.3 The Greenhouse Effect:
The build up of Carbon Monoxide in the atmosphere has increased dramatically. The
burning of fossil fuels, combined with deforestation & pollution by industrialised
countries has lead to the changes in the earth’s climate. Carbon Monoxide allows most
of the solar radiation to penetrate the atmosphere, but prevents radiating heat from
escaping back into space. The resultant climactic change means that the earth may heat
up between 1.50C and 4.50C within the next 50 years. If pollution were to cease
immediately, the detrimental effects would continue for a further 150 years. The
European Union’s commitment to the reduction of Greenhouse emissions to 8% below
1990 levels by 2008 - 2012 was announced in British parliament in May 1998 [19].Plans
are in place to restrict motor traffic in urban areas should pollution levels rise above
accepted levels. The possibility exists that access to town centres may be restricted to
non - polluting vehicles on specified days only thus restricting lifestyle choice. Indeed
in the Saturday Telegraph of 29th July 2000 Ken Livingstone Mayor of London
announced his plans to charge motorists for access to central London thereby
instigating economic controls on traffic.[20]
3.4) Deadly Soup:
The mixture of gasses emitted from a modern city are many and various, ranging from
Arsenic { coal and oil fired power stations}, Nitric acid {motorised transport},
Hydrogen chloride { incinerators}, Sulphuric acid {produced in sunlight from H2 S in
sewage treatment works} and Carbon Monoxide {all land and air transport, oil & coal
fired power stations}. The air breathed by the earth’s population on a daily basis
comprises all of the above. London smogs of the past resulted in extremely poor
N. J. K.-W. MA dissertation Ch. 3 Pg. 21
visibility. However the gases breathed today by London’s inhabitants are probably
more toxic than these “pea souper”.
The regeneration of cities has to take in to account the need for sustainable
development along side a reduction in pollution [21]. Less has to mean more. Less
pollution has to be combined with more housing in the form of Urban Regeneration.
“Over 90% of the population of the UK live in conurbations covering 10% of
its land area and it is estimated that, by the year 2000, half of the world's six
billion people will live in cities [22] ”.
The use of cities and the suburbs is therefore going to have more impact both now and
in the future than at any other time in our history. Energy efficient design and urban
regeneration projects need to work in synergy. Indeed the average parking space
allocation of per dwelling has shown a considerable decrease in line with Local
Planning Authority Guidelines.
3.5) Location, cause and effect:
Location of a development is extremely important and is in most cases influenced by
external factors. Tony Blair at a labour party conference prior to last election stated the
importance of
“Education, Education, Education”
In building a conurbation the developer’s cry has to be “Location, Location, Location”.
The soil structure and previous use of the site all contribute to the development cost
and therefore to the final production cost of the building to be placed on the site.
Global warming will lead to a rise in the sea level. History has shown that the sea level
has risen and fallen by 150 metres from ice-age to tropical climatic conditions. We are
currently living in an ice age, and the most stable climatic conditions the planet has
ever known [23]. Global warming may well upset this equilibrium resulting in the loss
of many low lying costal regions. This combined with the shift of the UK landmass
downwards in the south means that land such as the counties of Suffolk and Norfolk
may well be reclaimed by the sea thus exacerbating the overcrowding of the cities. This
will result in increased pressure on all urban conurbations within the next 50 years.
Re-planning of access routes throughout the country may be required. Indeed
N. J. K.-W. MA dissertation Ch. 3 Pg. 22
communication systems taken for granted today may be unusable in the future.
3.6 Who Decides?
Who should accept responsibility for the global energy efficiency debt? The designer
of the houses we live in? The developer demanding the lowest cost for maximum
profit? Or the end user for not insisting on the type of housing they wish to rent or buy?
A common factor influencing all the players in this equation are market forces and
economic necessity and if progress is to be made there should be a perceived advantage
to all parties..
Social and economic needs within the community will become the deciding factor in
a liberal democracy. The public should be protected from over zealous town planners
and dominant developers imposing solutions across the board. Cost-effective solutions
for the sustainable future mirroring the aspirations of the local population have to be
produced, in order produce harmonic developments in scale with the problems facing
the urban population of the UK.
3.7 The Challenge of the Future:
“The challenge is ... to mobilize, to start rebuilding a world that is in
ecological and human equilibrium[24].”
The B. R. E. D. E. M.[25] model was set up to assess energy loss as required by “Local
agenda 21". Energy consumption by domestic appliances is not assessed within the B.
R. E. D. E. M. programme's findings; but is the area where major energy savings can
be made. This oversight must be addressed.
Reduction in excessive use of domestic electricity, fuel, and water could produce a
more sustainable future. A reduction in room temperature of one degree reduces fuel
bills by 10% per room [26]. Condensing boilers can cut down the total fuel required for
heating the home and providing hot water by, 10 - 15% [26]. However the leading
manufacturer of condensing boilers has yet to produce a boiler of this type in it’s range.
The increased urban housing need is one of the great challenges facing civilisation
today. Housing schemes work best when the social needs of the local population are
N. J. K.-W. MA dissertation Ch. 3 Pg. 23
taken into account. It is important to establish how people wish to live and the impact
on urban design caused by transport, work, leisure activities, shopping, etc. Building
without reflecting these needs produces out-dated blighted building designs rapidly
falling into disrepair. Urban regeneration has to reflect the changing demands of
society adapting to the advances of communication, reflecting effective energy
efficient designs for a sustainable future.
3.8 Health Issues in Interior Architecture
3.8.1 The Western Scientific & Technological Approach
Heath issues in building are not a new science. However since Legionnaires disease
first struck a Midlands hospital [27] public awareness has risen. The symptoms of “Sick
building syndrome are no longer merely regarded as a mild sense of feeling unwell or
a slight headache. The real dangers of cooling and ventilation systems have now been
identified and the need has arisen to examine all cooling and ventilation methods for
buildings including those which had previously been regarded as “safe”.
The debate appears to turning full circle. Today buildings are designed with total
atmospheric control. The very microbes of life are being cleaned out of the air we
breath in buildings leaving the air with such a low moisture content that it can begin
to pose a heath risk in it’s self. Recent research into asthma has concluded that the
firstborn and only children of middle class families are most at risk from developing
asthma due to the excessively clean environment maintained around these children
preventing them from gained controlled exposure to toxins and thereby acquiring
immunity [28].
Current hospital practice bans all mains water without filtration from use as drinking
water, for fear of legal action should a patient become ill during an out-patient visit.
Micro-filtration is used to clarify, stabilise and sterilise all incoming water to remove
specific particle contamination, organisms which may spoil in addition to a final
sterilisation process to remove all microbial contamination [29] .
Health issues are not confined to hospitals. It is a sad fact that those living in a poorer
sociol - economic environment are at a higher risk of ill health than those in a higher
N. J. K.-W. MA dissertation Ch. 3 Pg. 24
sociol - economic bracket. A study in Canada by C. Waslishyn and J L Johnson (1998)
examined the effects and particular health problems of women living in a housing
association co-operative for low income women [31]. Their findings were that
“Living in poverty results in poor health, that the majority of the poor are
women” and most importantly “that treating the health problems of individuals
without consideration of the effects of the environment are doomed to
failure”[31].
3.8.2 The Oriental Empirical Approach to Healthy Buildings (Feng Shui)
Feng-Shui is defined by Ernest J. Eitel, one of the first western writers to document
this Chinese art in 1873 as
“ The art of perceiving the subtle energies of nature and the landscape, and the
science of reconciling the best interests of living earth with those of all its
inhabitants. [32]”
Although this explanation is succinct, a greater understanding at this point would be
of more use.
Feng-Shui has many facets and was envisaged as a whole life philosophy. Nearly three
thousand years ago an order to rationalise life was devised. I shall outline the two main
areas that will be expanded upon in my Master of Arts research studies.
3.8.3 Location, Location, Location:
In common with Architecture the concept of Feng Shui perceives location as a key
element in the fortune of the building and its inhabitants. Every Chinaman takes great
care in the siting of the tombs of relatives in order to ensure good fortune to the living.
As the site chosen for a burial place takes into account
“the happiest conjunction of all heavenly and terrestrial elements” it is clear
that the same rules can be used for the choice of a location for a home [33].
N. J. K.-W. MA dissertation Ch. 3 Pg. 25
There are perceived to be two different magnetic currents within the earth’s crust, one
male, one female, one positive and the other negative. The comparison to the upper and
lower portions of a man’s arm is made and the ideal site is considered to be
metaphorically speaking in the elbow region. Therefore it was considered favourable
to locate buildings or indeed cities at a point midway between two opposite energy
forces. Elevations of ground were considered to be landmarks which could be used,
rising land elevations were considered to be male and uneven softly undulating ground
, female. The favourable location of Canton City is cited as an example being situated
between
“the angle formed between two hills running in gentle curves towards the
Bogue, where they almost meet each other, forming a complete horse-shoe.”[34]
In all things a balance was considered necessary.
This then sets the parameters of a favourable or non favourable site upon which to
build. It appears to me that there might be a more rational explanation as to why this
set of criteria had been set in the first place. Might it be, for example that such a select
location has a greater advantage of being sheltered from the elements; wind, rain, cold,
and excessive heat? Additionally Eitel goes on to explain that the most undesirable
place to site a dwelling is one with no natural form of shelter or one that might in
today's engineering terms be more liable to slippage or subsidence.[35]
3.8.4 Ventilation, Ventilation, Ventilation:
The heart of the Feng-Shui philosophy as I see it is the doctrine of nature’s breath or
ventilation. They use this philosophy to explain almost every phenomenon in Nature
and once again it is seen as the spiritual energy of male & female principles [36].
The American model of interior architecture concludes with the need to control all
internal air within a building, down to the extraction of all undesirable viruses and
toxins. This man-made sanitised space that we are asked to live in works well on paper,
N. J. K.-W. MA dissertation Ch. 3 Pg. 26
as did the buildings which have now been classified as having “sick building
syndrome”. Is there ever a case for too much technology? Do we need to be separated
from our natural environment? Mothers nowadays clean down every surface in order
that their new born children may be shielded from what are perceived as harmful
bacteria. However although this may protect the child initially, it removes the
opportunity of the child coming into controlled exposure to these organisms and
thereby any chance of that child becoming resistant and gaining immunity to harmful
micro-organisms. Is this not doing humanity a disservice as they will then be ill
equipped to cope with these organisms when exposed in later life? Additionally the
deaths in native Eskimo tribes in Canada due to exposure to the common cold virus
carried by the settlers of their country is well known.
Has Feng-Shui anything to offer in today's society? In William Spear’s opinion society
today has become far too dependent on technology and computer aided design in it’s
search for energy conservation and has only just begun to see the consequences of
many of the proposed solutions on both the environment and the health of society as
a whole [37] . He feels that we should perhaps become more aware of the impact of
energy which cannot be as easily measured. Spear accepts that computer technology
is here to stay but feels that the designers of the future “will of necessity, use
intuition, instinct, and creativity much more in order to build vital environments
sensitive to the people who inhabit them.[37]
In conclusion I think that there is a possibility that some of the old world thinking of
Feng Shui may provide a few of the solutions to our energy conservation problems of
today. If by doing so this proves to be less damaging to our own health and well-
being then this would be advantageous. One of my guiding philosophies over the
coming months will be that
“the art of green design is not just what is put into a building, but what is left
out. The nicest systems are those ones you no longer need [38.]
N. J. K.-W. MA dissertation Ch. 3 Pg. 27
3.9 Low Energy Architecture:
3.9.1 A Computer Derived Solution for Beijing
Vanke City Garden, Beijing is the setting for the “computational fluid dynamics” trial
outlined in the paper by Professor Les Norford of MIT, Boston, USA entitled “Design
of natural ventilation and outdoor comfort by a team of architects and engineers with
the CFD technique”.[12] The paper investigates the effectiveness of use of a courtyard
of a selected building within a development to capture the prevailing south wind for
natural ventilation provision. The results showed that stack ventilation or assisted
ventilation would be required as the courtyard size made little impact on the ventilation
of the building. This was due to both low wind speeds and the proximity of a tall
building adjacent to the site and the resultant shadowing effect this had over the target
site.
A second study was undertaken mapping the effects of high-rise buildings on a site in
Vanke Doushi Garden Beijing [12]. A set of three designs were produced, each
developed from the results of the predecessor. The paper concluded that computational
fluid dynamics (CFD) were useful tools in the provision of natural ventilation and
thermal comfort in buildings. The CFD technique enabled engineers to calculate
airflow distributions in and around buildings thus assisting architectural design as
several alterations were required to gain the ideal environment both inside and outside
the building. This was a good example of interdisciplinary work.
Computer simulations without resort to wind-tunnel experimentations and the rounding
up errors associated therein demonstrates CFD tools to good effect. This is a positive
step, which may well lead to a reduction in the need for mechanical ventilation and the
wider use of natural resources.
N. J. K.-W. MA dissertation Ch. 3 Pg. 28
3.10 Sustainable Architecture for Low Income Housing:
3.10.1 The Boston Approach - Erie Ellington Project
Further to my meeting with Professor Les K. Norford and my interest in sustainable
architecture, I was invited to attend a lecture a t MIT. This was given by The Green
Village Group, a group of New England architects, and Energy Value Housing Silver
Award Winners in 1998, invited into Massachusetts Institute of Technology to give a
lecture on sustainable architecture
The Green Village Group had proposed the creation of a series of low-income homes
in Erie-Ellington Boston Massachusetts, USA, based upon a dry heating and cooling
system. This "Eco-Dynamic" system relies upon total control of the building envelope.
The flow of air is dependant in no small part on accepting less that half a square inch
leakage per one hundred square feet of external wall, roof, window, door, and floor
areas. By this control of "Infiltration",of air, heating is reduced by 30% giving an
overall CO2 reduction of 800 pounds per annum, over 50 years with corresponding
reduction in energy usage. The projected building cost was less than US$80.00 per
square foot rather than the local norm of US$107.00 per square foot [39] The energy
savings in these new homes are evidently so great that only one heating /cooling system
is required for a three unit-housing block, as opposed to a similar conventional design
which requires a system three times greater. The designs having been granted relevant
planning assent were in the early stages of on site construction in September 1999.
The advantages put forward for this design were the conservation of energy with a
corresponding reduction in condensation, a major concern in timber fabricated
buildings in the USA. The arguments focussed upon controlling the air flow through
the building. There was to be a highly refined control of air ducted to control both the
temperature of the building and to give clean air to the occupants. The mass production
of these modular sealed building units were to be controlled to a high degree under
factory conditions.
N. J. K.-W. MA dissertation Ch. 3 Pg. 29
Commendably this architectural group was determined to provide a workable low
energy, sustainable solution to a defined housing need. However the total reliance on
technology was seen as a panacea. The design of the buildings was a conventional one,
the building process having been tested and proved by the Canadian timber cabin
manufacturers to be successful, for more than ten years. The only novel aspect to this
project was the tanking of the external membrane.
The Erie Ellington project solution took no account of natural shading or the benefits
that this may bring to the housing project. Vitruvius, in 110 BC commented on how
the use of colour may substantially affect a building’s energy use [3]
It was his view that “In a hot climate, a white or light-coloured roof in combination
with well-placed shade trees can lower the building's cooling load by 30%”.
A project built in Israel in 1999 corroborated Vitruvius’s theory with an identical
energy saving of 30% through the use of a sophisticated shading system which was
additionally aesthetically pleasing [41].
It has become clear to me during the course of my research that single track solutions
purporting to solve energy efficiency problems do not take a holistic approach of the
way in which we live.
I was drawn to an article in “Health Estate” discussing the problems of unsupervised
smoking in dangerous areas following the introduction of smoking restrictions in
Morrison Hospital, Swansea.[42]. The problem of smoke filled buildings had been
resolved, but a secondary problem of litter and congestion at potentially vital escape
doorways was created in it’s place. Michael Corbett supports the argument that only
if a multitude of problems are solved by a single solution, can the upheld solution be
justified. He says and I quote:
"You are on the right track when your solution for one problem
accidentally solves several others. You decide to minimise automobile use
N. J. K.-W. MA dissertation Ch. 3 Pg. 30
to conserve fossil fuel, for example, and realise that this will reduce noise,
conserve land by minimising streets and parking, multiply opportunities
for social contact, safer for children." [43]
This single track approach has been enlightening to me and has given me the incentive
to investigate alternative solutions or combining proven technology such as the
solutions provided in places such as Beijing with vernacular architecture in order to
find a workable solution in the London area. For as Ted Saunders commented; “
Vernacular architecture is almost always climactically appropriate” [44],
Chapter 4: Master of Arts Personal Project
4.1 Personal project objectives.
This chapter set out to document my route through to a designed resolution of my
personal project. My underlying objective up to this point has been to highlight the
dilemmas associated with the paradigm of sealed buildings. To achieve the government
mandated energy savings, required in the 1992 United Nations Rio de Janeiro “Earth
Summit”, by the total dependance upon filtered Mechanical-ventilation systems is in
my view fundamentally flawed. Low energy affordable housing using passive stack
ventilation coupled with sustainability is an achievable goal. My proposal is to
demonstrate this. I identified three parallel projects that could be undertaken which
would each individually achieve this project goal:
1) A research based project; To collate related published research on
sustainable low energy domestic architecture. This would culminate in
the production of a “Teaching Manual”.
2) A design based project; To design a building demonstrating a viable
alternative to a Mechanically ventilated housing project, concluding
with the production of drawings, models.
N. J. K.-W. MA dissertation Ch. 4 Pg. 31
3) An education based project;. Production of a graphic based manual.
This manual would be produced to aid teaching regarding the benefits
of natural ventilation.
I felt that each of these projects were achievable initially. However as my research
progressed, it became apparent to me that all were achievable given appropriate time
and financial resources. Within the constraints of this MA programme however, I
concluded that it would be best to focus on project Two as the subject of my MA in
Design.
4.2 Introduction
Air in architecture is my defining theme for this MA personal project. My research,
outlined in chapters one to three, has focussed on low energy building materials,
environmental aspects to building issues, temperature loading of the internal
environment, and health issues related to lifestyle options. Linking all of these issues
is the movement of air through the internal spaces in a home setting. I therefore believe
that Air in Architecture is a link between low energy building, reduction or elimination
of sick building syndrome, and the opening up of the spaces within the home to create
a viable agreeable living environment.
Richard Rogers wrote in his book “Cities for a small planet”[45];
“half the energy derived from fossil fuels is consumed by buildings....According
to the Scientific American, the buildings of the industrialised world consumed
in 1985 an estimated $250 billion worth of energy...“Three-quarters of everyday
energy use in buildings is accounted for, in more or less equal proportions, by
artificial lighting, heating and cooling.”[46]
My aim is to develop a design incorporating sustainable technologies, whilst
simultaneously reducing its resultant pollution and running costs. The challenge of my
project is to reduce the energy consumption required within the domestic setting. I
N. J. K.-W. MA dissertation Ch. 4 Pg. 32
believe that this can be achieved through the use of low energy appliances, prolonged
use of natural lighting via opening up of internal spaces, and by viewing the function
of the core elements of the house. In view of the pressure on the environment today it
is important that my project design is sustainable. This is defined as the concept of
living and developing in ways which ensure future generations can enjoy the earth's
riches. In other words living today with tomorrow in mind.
I also considered whether a single housing project could be transported from an urban
to a rural site with little or no structural alteration? The Victorians were able to achieve
this in their terraced houses. The modern day equivalent is the terraced Berkeley Home.
These houses are seen in both housing environs with little internal restructuring, the
external appearance being influenced by the vernacular architecture of their
surroundings. My design proposal is therefore located in both an urban and rural setting
thus demonstrating a similar design flexibility.
Canadian and American buildings are currently receiving praise for their ability to seal-
off the external atmosphere from the internal environment. To achieve the desired
lowering of energy there is a reliance upon mechanical filtered ventilation systems.
“Passive Stack” ventilation on the other hand relies upon natural air movement
throughout the building, using stairs and natural air movement exhausting through
mechanical or passive exhaust ventilation systems thus promoting fresh air circulation.
Frank Lloyd Wright wrote in the New York Times on October 4th 1953;
“The physician can bury his mistakes, but the architect can only advise his client
to plant vines.”[47]
What would happen if architects' adherence to a single design ethos resulted in the
ability to prematurely bury their clients as efficiently? Should buildings be built at any
price? Is there a design philosophy that can provide low energy buildings and at the
same time provide for a healthy comfortable living standard?
My contention is that a multi-disciplinary solution will have greater health benefits
N. J. K.-W. MA dissertation Ch. 4 Pg. 33
whilst reducing energy requirements for the design. My design ethos is founded in the
augmentation of good ideas from around the world, and from the present and the past
alike, to create a workable alternative to the sealed building approach in domestic
architecture.
H. Kawada et al's Medical research [48] into airborne Tuberculosis at the Department
of Pulmonary Medicine, National Medical Centre of Japan, Tokyo, published in April
1998, concluded;
“this outbreak was caused by exogenous reinfection. Which may be one patternof tuberculosis transmission in this high-risk environment”[49].
Fig 4.2.1 Air circulation using natural gravity convection within a room
High risk environments are created by poor damp air conditions with stale air or air
that has been re-circulated with inadequate or non functioning screen filtration systems.
Victorian buildings designed with natural non mechanical ventilation systems fall into
this category when “upgraded” with sealed double glazed windows and doors, thus
providing an ideal environment for hostile bacteria to infect the inhabitants. The
increased use of Double glazing is considered to be one of the reasons for the increase
N. J. K.-W. MA dissertation Ch. 4 Pg. 34
in TB cases in the UK by some medical personnel.
J. Korsgaard's [50] research into the epidemiology of house-dust mites, carried out in the
Department of Chest Diseases, Silkeborg County Hospital, Denmark concluded that
in temperate climates increased indoor air humidity is directly related to the occurrence
of house-dust mites. Present-day building of energy-efficient houses with increased
sealing of the building envelope, parallelled by a similar renovation of older houses,
has increased indoor air humidity and is considered to be the cause of the almost
fourfold increase in the occurrence of house-dust mites in Danish dwellings. These
dust mites are considered to be the cause of asthma and other respiratory illnesses.
Recurrent incidences of sickness in long-haul aircraft has been frontline news recently,
with recurring reports of flight sickness in Boeing 777 aircraft. This has been attributed
to recycled air within the sealed cabin which is in essence the same principle as
controlling the air through the use of recirculating filtered air within a sealed building.
Recent studies have shown that the lack of exposure to micro-bacteria in newborn
babies and toddlers of up to two years old, due to over cleaning of surfaces by over
protective parents produces a higher incidence of respiratory illness [51]. It is likely, I
believe, that over cleaning of the air-borne particulates will produce simular results.
The introduction therefore of cleansed sanitised air as a major constituent of the
internal building's atmosphere could well produce similar results in the future.
N. J. K.-W. MA dissertation Ch. 4 Pg. 35
Problems with health appear to be linked to humidity levels, ventilation and filtration
systems, particularly with respect to recycled air. Fresh air must flow through a
building at the rate of 20 m3 per person per hour [52] in order to provide adequate
ventilation for the occupants. At this rate damp and the threat of mould build up is
reduced or eliminated.
Fig 4.2.2 Typical Victorian terrace of cottages, Downe, Kent. Photo Nick Wood 19/06/00
The Victorians used natural ventilation induced by draughts from windows and doors,
aided by open fires, to promote air movement through the building. Air moved from
high pressure hot rooms to lower pressured colder rooms. These rooms during the day
would be on the upper floor, thereby promoting air flow from the living rooms through
to the upper sleeping rooms and then venting out through open unlit fireplaces.
The modern equivalent Terraced house I have chosen for comparison is a Berkeley
Homes development in Westerham , Kent. “Austin Court” [53] completed by uses
trickle venting systems to replace ill-fitting windows found in the Victorian home.
Internal doors are fitted with integral louver panels thus promoting inter-room air
movement.
N. J. K.-W. MA dissertation Ch. 4 Pg. 36
Fig 4.2.3 Berkeley Home development, London Road, Westerham, Kent. Nick Wood 19/06/00
The designs are further aided by the introduction of exhaust ventilation in bathrooms
and kitchens. In my view, Fire regulations not withstanding, the boxed stairwell is
where the design inhibits air movement.
The Erie-Ellington project [54] , as outlined in the previous chapter, uses Mechanical
ventilation of a sealed building for both heating and ventilation. Whilst I have been
critical for the American dependance on the mechanical ventilation, climatic extremes
of temperature may require air cooling as part of the solution. However in UK which
has a more temperate climate and rarely experiences extremes of temperature, passive
stack ventilation could provide a solution. The Sealed building approach to architecture
for both countries may not be dismissed as lightly. This sealing of the building
envelope within the confines of both a European and American context is not only
unnecessary, but could in the long run prove to have detrimental health consequences.

4.3 Heat loading on buildings
Heat load of buildings has been seen to be dramatically reduced by the introduction of
natural shading. This can be provided by the proximity of buildings to shade giving
trees. Part of my design solution for this was to bring the shading onto the building
itself. This will be achieved by the introduction of balconies and planter boxes, the
planter boxes providing the environment for climbing plants.
Fig 4.3.1 “Sketch” drawing showing planter boxes and climbing plant climbing
N. J. K.-W. MA dissertation Ch. 4 Pg. 38
wires.
Drawing Nick Wood 19/06/00
Dr B. C. Wolverton, a Scientist working on the NASA breathable environment Lunar
habitat suggested [55] Such as Hedera Helix (English Ivy) and Ficus Benjamina natural
shading to grow up climbing frames attached to the front of the balcony.
The value of shade is only truly appreciated in the heat of the day. The value of energy
is likewise inversely proportional its availability but also carries hidden costs to both
health and the environment. The need to conserve energy through nationally enforced
guidelines has produced a multiplicity of solutions including those specifically related
to building design and construction.
Computerization of building ‘U’ value analysis have enabled assessments to be made
of enclosed spaces prior to construction. The hitherto hidden human cost to human
health associated with poor building design have also been established. Complex
interactions between building materials, contaminating partials, humidity, visual
stimulation, ease of usage, perceived air quality, produce complex analytical engines.
The removal of the human factor from space computations and concentration on single
building related issues simplifies the analytical engine. This reduces the design costs
whilst being seen to comply with the current building regulations.
My approach to this house design has been to open up the living space allowing air to
flow through the building, thus reducing or removing the need for mechanical ducted
ventilation. The design proposal took me through several convolutions before a
workable solution presented itself.
The list of specifications which I thought the proposed design should satisfy are listed
in appendix 1, and became the parameters for my personal project.
Research into a Victorian terraced house and a newly build Berkeley Homes
development provided me with current and past building prototypes to use as a point
of departure for my project. The Erie-Ellington project in Boston provided the catalyst
N. J. K.-W. MA dissertation Ch. 4 Pg. 39
to design a solution that was not dependant upon Mechanical ventilation for heating
and ventilation. From history I borrowed both the classical Palladian hierarchical order
of living and Vitruvius’s theories on the advantages of natural shading[40].
Chapter 5 Design projects
5.0 Personal project.
My personal project began with the specification of the design brief, as laid out in
Appendix 1. The starting point was the effectiveness of a profiled roof. I wanted to
produce a design in which the roof assisted in the extraction of the air within the
building. I thought that this would be achieved by rising heat creating a vacuum within
the building thus generating effective internal air movement.
5.1 Profiled Roof Project
When air moves over a profiled surface similar to that of a wing in an aircraft a
vacuum is created by a body of air moving over two or more surfaces of unequal
lengths. This was the theory that prompted my wing shaped design.
performance diagram shows the point at which stalling the wing occurs. It is at this
point that I need to introduce the step in the roof profile.[56]
N. J. K.-W. MA dissertation Ch. 3 Pg. 40
Fig 2.1.7 This shows the point at which the boundary layer effect de-laminates from
the wing surface. At this point the co-efficient of drag increases exponentially. It is at
this point that exhausting air from the building could be effectively drawn from the
building.
fig 2.13. [58] Illustrates the effect various shapes have on the air that passes around
them. A. C. Kermode[57]
Furthermore air flow over an interrupted surface generates a vortex. The introduction
of an escape vent at this point would enhance the extraction of air from the building.

These theories are acceptable for aircraft which have a predicted air velocity. Buildings
the other hand are in the main static structures that have air movement patterns flowing
past them at unregulated velocities. This became the undoing of this particular line of
design. Fig 5.1.3 shows this design. The reliance on the roof to provide the entire
answer to natural ventilation resulted in a single approach design solution, which was
the very approach I was looking to avoid.
5.2 Terraced house Project
Support from the MA course leader, Francine Norris, was provided by the suggestion
that I designed a terraced house comprising four units with the maximum external
dimensions of thirty metres by nine metres by eight metres height. The terraced house
was to have a single unit comprising a three bedroom house, one single bedroom
house and, two units comprising two-bedroom houses. Each house was to have two
horizontal planes and two vertical planes. One column only could be used. The vertical
planes were to be constricted so that one plane was twice the size of the other. This
suggestion enabled me to refocus the project from a different and untried angle. Neither
of us were sure whether this would work. Looking at the problem from a different
angle, far from being a insurmountable problem became an enjoyable challenge.
N. J. K.-W. MA dissertation Ch. 4 Pg. 42
Fig 5.2.1 Terraced house project 2
The solution lay in widening the creative boundaries freeing me from previously self
imposed restrictions . No rules were set for party wall conditions. This meant that by
splitting the development into eight units, and allocating each proportionally to each
unit, the 3 bed unit getting 3 x 1/8th and the two bed units being allowed 2 x 1/8th etc.
the zoning of the unit was achieved. The party wall was then offset by 2m each side of
the dividing unit, and further split at the floor levels. By bridging the twin party walls
at the first floor level a bathroom space was created for each without the need for
additional internal walls. Double height living spaces were created from the ground
floor, with the stairs providing vertical communication between the floors. This
enabled me to achieve some of the opening up of space that I had been searching for.
Fig 5.2.1 shows an exploded view of this project.
However there were problems with this designed solution. The terraced outer units
were orientated through 180 degrees to the inner two units. This would have proved
unworkable in a terraced scenario with front access only. Additionally the splitting of
the party wall would result in increased building costs and present constructional
problems. Twin Rolled Steel Joists would have to be set on twin footings thus doubling
N. J. K.-W. MA dissertation Ch. 4 Pg. 43
the construction cost for this item. Another problem with the proposal was the lack of
identifiable main access points to the building.
Notwithstanding the project was successful in that it allowed me to break free from
pre-conceived ideas of spacial design. This enabled me to look at the problem from
hitherto unseen dimensions. This enabled me to reconstruct the project using the
lessons learned. The project had not yet addressed the facade detailing, nor indeed was
it designed to do so. The next stage in design would need to look at this aspect of the
problem.
Fig 5.2.2 shows development of terraced house, 2 Bed unit. Drawing Nick Wood
N. J. K.-W. MA dissertation Ch. 4 Pg. 44
I decided it would be beneficial to take this proposal further. With this floor plan layout
I wanted to explore the aspect of through ventilation and use of stairs for more than
vertical access.
Zaha Hadid’s work [59] with ramps which provided sloping vertical access from level
to level was of interest to me. Using stairs for mere vertical communication looked on
the face of it a waste of good living space. Lifts , if they were reliable and not energy
dependant would be far more use and less floor area intensive. Stairs were however the
low running cost solution that I needed for this project.
Using the inter-floor landing as an office space afforded one solution. This had the
ability of breaking away from single floor living. Stairs now could become living
spaces in their own right. The mezzanine floor accessed from the second inter-floor
landing would have had far reaching design implications. In this version the mezzanine
would have triangulated supported from the external front wall, the inner party wall
and the inter-floor stairs. Access to the second level balcony would be from this
Mezzanine floor, affording a one and a half floor height external frontage and a greater
feeling of openness and freedom of movement, when seen from the living room.
Enhancing the flow of air through the building was the next task. By opening up the
first floor landing corridor wall, air could move from the front to the back of the house
creating cross ventilation. Opening up the bedroom floor to create a double height void
through to the diningroom below would increase the flow of air through to the back of
the building. However the cost of this would be in building interrupted floors
necessitating the introduction of RSJ support at the floor edge. Noise from the dining
room to the bedroom, and vice-versa could prove to be a problem. However with a
young child in the bedroom, parents could keep a ear out for them and still enjoy a
meal. The bathroom followed a conventional type and would need fan extraction to
avoid steam buildup. Access to the rear balcony would be through the bedroom.
Several more lessons had therefore been learnt for the next design stage. Presenting
these findings to Francine Norris and peers proved useful. Colin Perrott was
N. J. K.-W. MA dissertation Ch. 4 Pg. 45
informative and encouraging. His enthusiasm spurred me on when the thought of
“starting again” began to take its toll.
5.3 Air-tech-Homes
Fig. 5.3.1 Stairs with house attached. Stage 1 Fig 5.1.3 Drawing Nick Wood
Having finished the terraced house project and following the ethos of Eugene
DeLacroix who said that he never knew whether a painting was finished until he went
too far and ruined it, the MA proposal then took another turn . What had started out as
a straight forward project was now becoming complicated . Having seen that the main
principles could work, it was time to develop a project which was taken to completion
. Time was running out and the design needed to be finalised . I decided that the house
was really stairs with a house attached and I therefore started with this ethos in mind
putting in an entrance door to give a 1,2m corridor and then stairs directly beside it .
The rest of the house would be hung off these features .
This is not the conventional manner in which I had designed houses in the past but as
I have already demonstrated, producing conventional designs can be dangerous. It was
liberating to be able to start the design from a different angle. I was now looking at
buildings in a similar manner to the deconstructionists albeit in a limited way. I took
the building apart and reassembled it to see how it would fit together again. My design
to date had not demonstrated the unconventionality of some, such as the use of spirals
N. J. K.-W. MA dissertation Ch. 4 Pg. 46
rising through the building, in the manor of Liibeskind [60]. In effect I was making use
of the stairs to go up through the building, but making them a larger feature than
hitherto deemed appropriate in a domestic setting. I wished to make the stairs part of
the living building rather than a functional apology stuck on the side. This alteration
allowed me to open up the living area to a 1.5m - 2m height void allowing a greater
freedom of movement of both of air and of intellectual space for the inhabitants .
Fig 5.3.2 Full section of house prior to forming terrace. Drawing Nick Wood
My critics would say that this is a needless waste of space as the last square millimetre
of useable space has not been packed onto every floor. In my opinion that particular
approach produces “shoe boxes” that are neither elegant nor practical and destroy the
soul of the occupants. I would like to design a house that has more flow and movement
than conventionally found in low income housing. I am relying on tried and trusted
building techniques. In doing so I aim to prove a point on construction that designs
unconventional in their layout can be effectively built. By moving the sleeping quarters
on the upper floors which are in the Palladian mode to one side of the building I was
able to open up the living space below to allow more freedom for light and air to
penetrate into the heart of the building. By sloping the roof on a curve what I was able
to tuck the stairs underneath giving the semblance of a wave pattern or movement that
air would be seen to make if it were visible. This pattern is reminiscent of the wing
profiles that I was using in the initial stages of the project but in a more stylised form.
N. J. K.-W. MA dissertation Ch. 4 Pg. 47
Using flat plate simplified the construction and I felt justified in using a wave pattern
on the lower roof through the introduction of laminated timber beams. The cost of this
would be offset by the reduction that I would obtain from energy efficiencies elsewhere
in the building. At this point glazing materials needed to be considered. I had looked
at conventional double glazing units and concluded that the argon filled low energy
glass double glazed units were those that I wished to use in the design. Whilst more
expensive than conventional double glazing, the energy efficiencies gained from these
more than off set the initial purchase price.
My aim was to design a building which year on year would give savings even though
the building cost may be slightly higher than the standard energy efficient home today.
It is my belief that investment in the future will pay off fourfold thus creating
sustainable development. I did not want to follow the line of saving money in the short
term to the detriment of long term savings. Investment in infrastructure at the time of
building allowing householders to reap the benefits over the life of the house, a time
span of some 50 years is in my opinion more acceptable than saving money by building
cheaply initially and retrofitting with energy saving strategies. Currently this is
happening frequently under local agenda 21 mandated schemes, where local councils
are obligated to update their housing stock . This places an exponentially high cost on
the energy debate and in a lot of cases is mere window dressing.
Double glazing has a payback period of over twenty years compared with wall
insulation or low energy lighting with payback periods of two and a half years and
several months respectively. These strategies are therefore more cost effective to
implement. In theory, the opening up of the roof with Velux windows should result in
prolonged daylight infiltrating the building thereby decreasing the amount of energy
required to light the building particularly on overcast days.
The Sainsbury Centre for Visual Arts, University of East Anglia, Norwich where
Foster Associates[61] encapsulated louvres within the glazing units thus saving cleaning
and maintenance of those systems was the inspiration for my next idea . Once the
double glazed units were installed as an argon filled system, I envisaged the
N. J. K.-W. MA dissertation Ch. 4 Pg. 48
encapsulation in the remaining frame of a louvre sealed with a sheet of glass. This
would result in the same effect as was achieved at the Sainsbury centre but at a fraction
of the price. The roof lights would have mechanically operated louvres running on
solar voltaic cells with power back up for cloudy days.
Additionally Domestic hot water systems would be supported up by additional roof
radiators thus augmenting the heating system and reducing energy consumption.
Household grey water would be stored underneath the building and circulated back
through the planters which would also act as reed beds purifying the water.
Alternatively reed beds could be planted on site and the purified water then pumped
back into the dwellings to be used both internally and to irrigate the balcony systems.
Reed beds result in 99% water purity, well above domestic requirements but I aim to
use the recycled water only for irrigation purposes and for spraying onto the plants
thus creating additional cooling effects[62] Although pure enough for domestic
consumption, in the absence of considerable public education and promotion this may
prove unacceptable in some households. I therefore intend to use a dual system, one
for water which is recycled and one for mains water entering the house which will be
used for drinking and bathing. Bathwater will be recycled as grey water and can
additionally be used for the WC systems. Rain water collection will be through down
pipe filtration which will go into the main collection tanks augmenting the grey water
and to be used for irrigation purposes.
At this stage the design had taken on an orthangonal orientation and thus quite closely
was following a conventional design. The design was put up to full visualisation with
the construction and detailing of the interior surfaces and the construction of the
external walls. The house was now complete. However when the three were placed
adjacently as a terraced development, the design began in my opinion to look very
ordinary, uninspiring and lacking in architectural movement. This design would not
represent the movement of air within the internal spaces which had been a key design
element.

Lessons learnt earlier, particularly that of not changing direction completely until the
full design potential had been explored now payed dividends. I continued with the
design development establishing whether any further lessons could be learned. In order
to make the building more dynamic the stairs were rotated and relocated relative to the
front door. I then looked at the effect this had on the building as a whole.
The opportunity to attend a lecture by Zaha Hadid presented itself [59]. I empathised
with her unconventional style and approach. This was epitomised in her sketch for a
tennis court, which initially appeared unworkable but on further examination was
plausible. The exploration of the seemingly impossible resulted in the final stage of
design, which is now my design proposal.

I have found the project design notebooks of great value to me throughout this design
process. Personally, this had been an underutilised medium previously, the computer
having been used in preference.

I returned to the roof and looked at the flat profile 300 roof pitch. I looked at what
would happen if I took the ridge and twisted it across the floor plan, running the ridge
N. J. K.-W. MA dissertation Ch. 6 Pg. 51
line from the centre of the rear of the building and allowing it to crash into the front
facade, at about 25o to the perpendicular. The effect was quite startling. The hidden
central recess of the building opened up, not only to light but equally importantly to air.
This allowed movement of air throughout the building presenting me with a great
opportunity, which I have now taken full advantage of. I attended a lecture by Zaha
Hadid at around this time and was fascinated to see her design proposals. There were
striking similarities with my own ideas. This gave me the resolve to progress with this
design proposal.
The final design is a set of single pitched rooves with a rotated ridge line. On the front
facade, a shed roof runs up from the first floor over the second floor mezzanine. When
two units are therefore placed back to back, the resultant appearance from the front
facade is a “conventional” two and a half storey house. This gave me a tremendous
opportunity. The front facade could now can be treated to fit in with an ultra modern
street setting, or conversely with a traditional village setting. Only when proceeding to
the rear of the house is the Deconstructionalist nature of the building revealed. Thus
finally I was able to satisfy this particular design criteria, that of transferability of
location of the design.
This was not the prime motivation for this line of thinking but had quite a beneficial
side effect.
“You know you are on the right track when your solution for one problem
accidentally solves others.” [64]
I had at the stroke of a pencil, produced a design addressing more than simply the
original design criteria. The design will work as a terrace, a semi - detached or a
detached house, and can be expanded or contracted to suit the occupancy numbers. The
flat sloping rooves are also less costly to build than the wave form of the previous
design.
The turning of the stairs through 300 allowed freedom of movement within the
building’s internal layout while the placing of the stairs in the middle of the building
N. J. K.-W. MA dissertation Ch. 1 Pg. 52
opened up the building form. This freed up the front of the house for the kitchen and
entrance hall providing a conventional entrance scenario. This was the solution I had
been long been searching for.
The stairs could be used as part of the living space rather than merely effecting
transition from one plane to another. The space below the inter floor landing could be
utilised for grey water storage with storage of purified water also contained within the
same space. The area under the return stairs has been utilised for a work desk placed
on a pivot in order that it may be used either in the storage position, or rotated out into
the living space as the householders desire. The inter floor landing is designed to be
used either as an office or a library.
The design perimeter started off as a recta linear form. This developed along the
courtyard elevation into a sawtooth profile due to the need to afford privacy from the
adjoining terraced house. The rearward facing elevations have glazing panels set into
them whilst the return faces are flanking walls. An example of this design form can be
found in Basel Spence’s design for the Guards Chapel, Birdcage Walk, London, built
in 1962.[65]

Windows for the project are to be Argon filled sealed double glazed units. A third
glazing pane encapsulates a solar powered mechanised louver blind system, inspired
by the design for the Sainsbury Centre, University of East Anglia, Windows have
been set into the roof over the living area. This enabled the provision of additional
daylight, another design criteria. Additionally it afforded a greater degree of ventilation
options for the occupants.
At the junction of the roof above the living area with the first floor walls, ventilation
and lighting opportunities have also been created.
6.2 Project Summary
This paper has been produced as part of my Master of Arts project report and should
be read in conjunction with the MA show held at KIAD in September 2000.
Sustainability is not a simple subject. I have therefore been able to only scratch the
surface of this subject. Low energy naturally ventilated housing combined with
“healthy holistic” living is the main thrust of my project proposal. The first three
chapters show a progressive development of my understanding of the subject, and an
introduction to the complex interrelationship between technological solutions and their
impact on the environment. There is a need to highlight the true cost to human health
of single track solutions. Research into this subject has been outlined within the first
three chapters. chapters fourth, five, & 6 documents the design project required by the
MA programme. My research has been aided by the use of a qualitative analytical
programme Nud*ist N4. This has enabled me to collate both logical argument and
source materials efficiently thus allowing me to cover the subject in greater depth in
preparation for my doctoral studies. This paper therefore should be read in part as an
application to carry the research forward at doctoral level. This project is by no means
over...This is just the beginning.
Additionally the following key linking findings were uncovered by my research:
i) air bourn diseases are linked with an exponential rise in filtered mechanical
ventilation. [1] 3.8
ii) Asthma is linked with sealed buildings.[50], [48],
iii) The rise of dust mite infestion rose in-line with the fitting of double glazed
N. J. K.-W. MA dissertation Ch. 6 Pg. 54
housing. [50]
iv) Passive stack ventilation can be linked with heat recovery systems. 3.8.3
v) Fresh clean air is better than filtered air.[55], [52]
vi) Single issue solutions bring with them many unexpected seemingly unrelated
problems. [36], 4.2
vii) Passive stack houses are better than mechanically ventilated ones, provided
they are well designed.3.9.1 4.2 [1]
viii) An Holistic approach to design is the preferred design option. [36] 3.2.8
ix) Heat loading can be reduced by green shading [40]
The project design solution proposed at puts forward one possible solution to the low
energy healthy living debate. I have shown through my research reasons why the
building should be produced as a holistic design, avoiding single faceted solutions to
solve complex problems. The design has movement and openness. Both of these are
essential to my project brief. Having produced four design proposals, the final one is
the design which satisfies both the core requirements and aesthetic aspects of the
design. I am satisfied that this solution can be built and that it will deliver energy
savings whilst providing a healthy environment in which to live. Furthermore This
proposal should provide a starting point for the next phase, that of a doctoral research
project.
