1 INTRODUCTION
This report will feature an in depth look at the design aspects in regards to the ‘The Ship’. This will be done by analysing the requirements of an intelligent building outlined in the project specification and applying these within the chosen design. The project specification has been drawn from expectations and assumptions made both prior to and during the project, regarding the design of an intelligent building. A major factor governing the design of the project will be the wants and needs of the interested parties in relation to ‘The Ship’. These will be identified within the report and then taken into consideration throughout the design of the project.
The main focus of the report will be the actual design aspects with a number of preliminary ideas discussed, including advantages and disadvantages, before deciding on a final design. This will be followed by a detailed description of the building and floorplans of each floor within the building.
The systems including fire, security, lighting, space saving and environmental will be described in detail with appropriate research and some examples of ways in which these systems will be implemented.
This report will also touch upon the costing of the construction of the building as a whole, followed by a risk assessment evaluating the potential for error regarding the construction. The conclusion of the report will discuss whether the project has been a success or not judged on whether objectives were met and the learning experience of the project.
2 AIMS
The aim of the project was to design an intelligent building that would meet the needs of its
occupiers in that it creates an optimal environment for its purpose. This means that the
building has to be both adaptable and flexible whilst being both functional and efficient. This
can be done in numerous ways including multi-functional open spaces, energy efficiency and
complete systems integration. One of the other key concepts of an intelligent building is to
have reduced maintenance and operating costs but is worth more to its occupants. The
design of ‘The Ship’ has tried to incorporate all these factors in to its design and foremost to
create an enjoyable and comfortable learning environment.
3 INTERESTED PARTIES
In order for the proposed building design to be classified as an intelligent building concept, it
must first be able to provide for the needs of its occupants. For this reason the building was
specifically designed with a select group of people in mind the interested parties. In order to
create the buildings specifications, an assessment of the buildings occupiers must be drawn
together to work out the requirements of the intelligent building.
5
3.1 Identify the interested parties.
As the Building is designed to be a multifunctional university facility, the interested parties
that would be proposed for the project are a narrow field with three separate tiers of
involvement.
The primary parties are those who would be using the building on a regular occasion. The
primary interested parties for the building are Plymouth University Students, Lecturers and
Staff. Secondary interested party members are. For example those who would have access
to the building in off peak periods. For example Businesses, Researchers and PHD/ Thesis
mature students/ post graduates. Final the tertiary interested parties who would be those
who are interested in the building but for their own purposes and would infrequently use the
building.
3.2 Identify the needs (wants) of the interested parties.
The primary parties are the biggest users of the building; students who would be using the
building for daily for revision space, group work areas and lectures. The lecturers would also
be primary party member as they would be teaching in the 3 lecture theatres or assisting
students in the open planned study area. The final group within the primary interested party
members are the staffs who were displaced from Portland villas that for obvious purposes
will be rehomed within the buildings offices.
Within the secondary interested party members are Businesses who would be interested in
the building for its seminar rooms or lecture theatres for those who require space for a large
presentation, as well as the fact that there is plenty of space for advertisement of services
within the buildings floorplan and it is a prime location on site to host business fares to entice
students. Researchers or people doing there PHDs/ thesis post grads would also be
secondary interested parties and use the building in off peak times or who require quiet
spaces to do their work.
Finally the tertiary Interested are those who are interested in the building for their own
purpose and would not be frequently using the facilities; for example the Plymouth city public
who will obviously care about the aesthetics of the building and would care about the
reputation of the university. Another aspect why the public would be invested is that during
summer Plymouth University is known to let out its halls and facilities to summer schools.
4 PROJECT SPECIFICATION
The design specification is an important process for the project brief as it has to represent all
of the intended key features of the building that would be required by its future occupants
needs. Items listed on the design specification must be applicable to any and all of the
design ideas, so that when the buildings initial ideas are planned they are done so with
these requirements in mind. It also is vital to help select the most appropriate building
concept, the requirements for this brief’s designs are:
6
85 offices to replace the buildings offices that originally stood in the designs footprint
4 Lecture Theatres for class learning
20 Study Rooms for group and quiet study/ working
Café on site
Toilets on every other floor (both male, female and disabled)
An IT area solely set aside for computer based working
A control room to control and monitor the buildings inner workings
Large reception
7 Tutorial Rooms large enough to seat over 150 students
3 Faculty Offices to replace the ones from the pre-existing building
Open planned
Well laid out and informative floor plan
Adaptable working environment
A challenging & smart design
Atheistically pleasing
Modern design that fits in with the target location
Environmentally friendly/ Energy Saving
Local
Benefit populous
A “Smart House” intelligent systems
Cost effective
Efficient use of space
5 THE DESIGN
5.1 Options Evaluated
By deciding to build the building on Portland villas adequate use of spaced, creative iconic
design and energy efficiency were key factors to the design. The first idea (Figure 1) was a
hexagonal building that would contain a consistent floor plan throughout to allow intelligent
use of space and consistent floor designs throughout the building. Although this was
favourable the long but narrow plot of land would not allow space for a symmetrical
hexagonal building.
(Figure 1)
7
The Shape of the land was considered and a long rectangular building was decided with
open study spaces, cafe spaces and office spaces on the top floor (Figure 1). This
incorporated the same modular floor plan idea from hexagon building; however this lead to
the problem of the building being a standard rectangle building. This did not fulfil the iconic
design requirement for the project.
(Figure 2)
8
Second sketch of a possible building design where the standard rectangle shaped building is
incorporated.(Figure 2)
For iconic aesthetic purposes that would fit in with the ethos of the city a building
shaped like a ship was designed (Figure 3 – 3a Drawings). The first exterior Solid-works
model was made (Figure 4), however the initial plan did not translate into an iconic design as
the reverse ‘bow’ and straight sided office tower did not exude the visualisation of a ship and
had to be re-designed.
(Figure 3)
(Figure 3a)
9
(Figure 4)
Figure 5 shows a developed version of figure 4. The previous design shows tower walls
being straight, Figure 5 shows that the tower being angled and fully developed ship. The
straight ‘bow’ of the ship increased the useful floor area and made the overall design less
complex (Figure 5). The floor area decreases the further up the building goes. (Figure 6)
(Figure 5)
(Figure 6)

5.1.1 Environmentally friendly design aspects
A fuel cell would be chosen to supplement or completely supply the electrical needs of the building. The initial was the 160 KW Bloom box that would cost between ($700,000-800,000) operated off of methane (Quick, 2010) and convert excess heat into electricity stored in batteries. However this option was too expensive, inefficient (Appendix – 7 Reconsiderations-Thermos) and continued to produce small amounts of CO2.
The final design utilises a solar-hydrogen system that uses cheaper (£ 660/KW) and more
efficient Redox Fuel Cells instead and heat for passive building utilities and services
(discussed in Chosen Design).
5.2 The Chosen Design
The final Ship idea (figure 4) was chosen to be taken into development this was because the
design the most fitting when compared to the project specification. With the Ship shaped
building the iconic aspect was fullfilled as it looked as though it was sailing out into the
adjacted round about space to motorist passing by. It also encompised the space and
environmental functionallity of the previous design conciderations.
5.3 Detailed description of Chosen Design
The final chosen design constructed via Solid Works (Figure 7).
(Figure 7)
The heights of each floor was decided to be 4 metres high for each level, with a 1 meter
space between the floor and drop ceiling to allow space for ducting, plumbing and electrical
conduits to occupy. The rear section of the ground floor was required 8m high in order to
accommodate adequate floor height for the (3) lecture theatres from floor to ceiling. (Figure
8)
11
(Figure 8)
(Figure 9)
Figure 9 shows the reason why with the office tower were tilted at a 102.68 degree angle. In
order to increase the amount of sunlight to enter the building year round reducing lighting
cost. However the solar panels play two roles and act as shades to prevent excess sunlight
from overheating the building during the summer months. The angled sides act to increase
surface area and a rain water guide to increase the amount of water collected by the building
and channelling it to the tank reservoir.
Ground floor layout description
The ground floor of the building has been produced so that it had the tallest ceilings in
comparison to the rest of the building where half the floor has a height of 8m this has helped
to design a visually appealing open space floor plan, which produces a sense of freedom to
12
move freely, this also helps to integrate the ideology of an intelligent building. The group had
come to the conclusion that the following features needed to be implemented on this floor:
lecture theatres, faculty offices and the reception.
There is a total of three lecture theatres in this building were two have taken the shape of a
rectangle. The third lecture theatre is much larger but this was produced with the intention
that it can be split up into two smaller lecture theatres, this is in the shape of a semi-circle
holding a much larger capacity, the benefits of this would not only cater for the more
populated university subjects it can also be used to host large events such as university
open days. All lecture theatres are situated the back of the building were the height of the
building is at its highest as shown in figure 10. As mentioned before the building needed to
accommodate for all the offices and faculty offices that were located in the current Portland
Villas building. Currently Portland Villas hold two faculty offices these will be presented on
the ground floor. The faculty offices are produced these are situated near to the middle
section of the ground floor as shown in figure 10. A circle shaped reception will be situated at
the front of the ground floor. There are four entrances to the building two on each side as
shown in figure 10 each entrance will have a revolving door to prevent heat loss alongside a
conventional door as shown in figure 10.

First Floor
The first floor of the building will consist of 10 medium size study rooms aimed at students
doing group study or for the use of small tutorial sessions. These rooms will be bookable
through the university website to allow students to reserve study space. The open area at
the front will have more seating that can be used for study or socialising. Included on this
floor will be the systems control room, this will act as the central hub in which all the fire,
security and safety information is processed and monitored. Below is an image of the
floorplan.

Second Floor
The second floor of the University building will be focused on study space for students.
There will be 6 large study rooms, varying in size, which will offer the much-needed group
study areas. (Located at the back of the building) The front half of the floor will consist of
many tables, to offer individual/small group work with the rest of the space being taken by
computers, some relaxation areas and the toilets. Below is the floor plan for this section of
the building.
Figure 13
15
Café
The café will be in place in order to offer food and drink both to students and staff and also
as a place to socialise without disturbing others. The café will have small kitchen facilities but
it will mainly serve cold food and drinks. Being situated on the third floor and with large glass
windows the café will have appealing views across the city. Shown below is an image of the
solid works model for this section of the building.
Figure 14

The offices
The ship will be built in the location of the existing Portland Villars. Currently the Portland
Villars is used as office for university staff. The ship will create a total of 88 offices which will
replace the existing offices in the Portland Villars and also create some spear offices which
will allow for expansion of the university in the future.
The offices will be located over four flours and will be in the tower at the rear of the ship, as
shown in figure 15.
Due to the irregular shape of the ship, the dimensions of each office do slightly vary for one
another. However each office is approximately 5mx8m. Below, figure 15.1 shows a typical
office. The full office dimensions can be found in the appendix.

5.4 Systems
5.4.1 Lighting Systems
Purpose
Intelligent Lighting systems will be used throughout the building to help save energy and
create a comfortable learning environment.
Motion sensors
Occupancy sensors (commonly referred to as motion sensors), will
be installed throughout the building. These sensors will
automatically turn the lights on when motion is detected within a
room and then switch the lights off once the motion stops being
detected. The occupancy sensors used will be the OSC20-RUW by
Leviton which is shown in figure 16. These sensors use a
combination of passive infrared and ultrasound to detect
motion and can be mounted to a ceiling. They provide a large
coverage through 360 degrees, making them useable in all
the rooms throughout the building. They cost approximately
£100 per unit which although is relatively expensive, will help
save energy and hence save money in the long run.
Energy efficient LED lightbulbs
Energy efficient LED lightbulbs will be used throughout the building.
The lightbulb used will be Philips 433227 60 Watt Equivalent Slim
Style A19 LED which cost just over five pounds per bulb (Amazon,
2015).
Studies have shown at these lightbulbs are almost six times more
efficient that Incandescent bulbs and over four times more efficient
than Halogen bulbs (Wikipedia , 2014).This will help preserve energy
and in doing so save money as support the universities
environmentally friendly image.

Natural light and remote control blinds
The design of the ship was created to best optimise the use of natural light sources. The
outside shell is made using clear glass which is transparent to let light enter the building. The
level of natural light entering the building can be reduced if necessary by
using remote control blinds.
Dimmer switches
Dimmer switches will be installed throughout some rooms of the ship to
select the desired level of lighting in the room. Lecture theatres
will have dimmer switches installed which will be used, for
example, when presenting PowerPoints from a projector. The
switches cost £9.40 per unit (screwfix, 2015).
5.4.2 Sound systems
Purpose
Sound systems will be installed throughout the ship to help remove
unwanted noise and to increase the clarity of vocal communications.
Unwanted noise pollution will be reduced using sound absorbent
materials in the construction of the building and also with the
instillation of high quality double glazed windows. Double glazed
windows can be supplied through a company known as Christil
Glass and will cost approximately £50 per m2 (Christil Glass, 2014).
Sound systems such as microphones and speakers will be installed
throughout lecture theatres to help increase communications between
the lecturer and the students. Tannoy systems will also be installed
which can be used for wide range communication across the building.
19
5.4.3 Sanitation Systems
Purpose
The purpose of sanitation systems is the use of intelligent devises and methods such as
recycling to reduce waste, which in turn reduces cost. Sanitation refers to the safe disposal
of human excrement and also the maintenance of hygienic condition through waste water
disposal (World Health Organization, 2015).
Rain Water Toilet Flush system
This is a system currently used on campus in the Roland
Levinsky building. This system works by collecting rain water
while working alongside the typical water mains to flush the
toilets within the building simple system of this is shown on
figure 5. This helps to cut cost as water bills would reduce.
These systems tend to cost next to nothing to implement
Waterless Urinals system
The use of waterless urinals is becoming very popular in many
industries and organization it helps to reduce water consumption
and also reduces the amount to waste water produced. Aquafree
Urinal maintenance Device cartridges cost £24 per unit and last
around a 3 month period however can be bulk bought for a
friction of its cost.

Heated Taps system
The use of a, at the source heated tap system would be
beneficial as it would allow the instant flow of hot water
when required. This is very economical in comparison
to the conventional boiler system that uses pipe lines
across the buildings to transport hot water, as the
heated water via the conventional system would lose
heat energy during transportation, Also when the taps
are not in use the heated water would be sat in the pipe
lines and this will eventually lose all heat energy and be
regarded as waste and overtime this can be costly.
Boiling water tap system will work perfectly and the
temperature can be adjusted so that the water
dispensed is the perfect temperature. Simple models
such as the SST-FLTR 2/3-Gallon Stainless Tank and
Filtration System can be bought from Purbeck
Plumbing & Heating at a unit cost of £272.95
Double Toilet Flush System
The double toilet flush system is a very cost effective way to
save money. An average flush uses around 13 liters of water
however the double flush system has that option but also come
with an additional feature, the smaller button is a lighter flush
using only half the water in comparison to large flush this
alternative is used when a large flush is not required. The
product UNIVERSAL Push Button Dual Flush System can be
easily purchased from Bathroom Technology at a unit cost of
£17.25

5.4.4 Environment Systems
Purpose
Plymouth University has well-known reputation of a green and environmentally friendly university around the country so therefore it’s really important to match or even stretch the reputation. One of our biggest concerns when designing an intelligent building was the effective use of heating and electricity. After completing research its clear to identify which part of the building heat lost was a major problem.
There are a number of control devices that will help contribute to the environment. These controllers will turn off light and heat when no one is using the room or part of the building. This will reduce the cost of running and maintaining the building.
Ventilation
Its a key part of the building as it exchanges fresh air into
the building which helps to protect the building against
damp and condensation. Unneeded ventilation can wasted
a huge amount of energy which will cost the building a lot
of money. Energy lost is one of the biggest concern for
most modern building with 35% of heat is lost through
ventilation. Unfortunately ventilation can waste energy
meaning costing the university a lot of money. The cost of
each ventilation is £6000. [2] Inserting high efficient fans
and motors can reduce 10% of heat lost due to less
resistance when operating, they need to be replaced
throughout the years as they do slow down and lost their
quality over the years. As you can see from figure 3 below that cooler air enters the building
through windows for a sense of comfort to the building whilst hot air raises and escapes
through ventilation fans.
Windows
Windows are another big issue when heat is wasted from the building with 16% of the total heat lost. This is why pressure is constantly growing in making glass windows more energy-efficiency to a point where double glazing will no longer be useful in the future. So it clears that triple glazing windows are the
Formatted: Font: (Default) +Body CS (Arial), 11 pt, Fontcolor: Black
22
new futuristic energy saving windows. They are good for the environment because it maintains its ideal room temperature of 21 degrees. Windows contribute to a large amount of heat lost. But after researching and comparing triple and double glazed windows it was concluded that the payback time is very high compared to double glazing. The cost of triple glazing is considerably high and only absorbing an extra two degrees which means that payback time is a longer than double glazed windows.
Plants
Plants are important features of a green building. It bring a friendly touch of open space to the
building with the feeling of comfort of rich oxygen in the air. Oxygen being released from
plants through the respiration system whilst carbon dioxide is taken. Reducing the level of
CO2 will help with global warming. Global warming's is having significant and harmful
effects on our health and climate. Sea level is rising faster than ever, the number of
deforestation is alarming, dangerous heat waves are becoming more common, extreme storm
and draught events are increasing in many areas. The ship building will include an outside
cafe that will be surrounded by plants and grass.
Rainwater system
Rain water is the collection, storage and distribution recycled rainwater, for the use of various different residential or commercial environments. Rain water collection is another part of the building which help influence to the environment with an average of 85,000 litres of rain water falls on building roofs in UK each year with many benefits such as Significantly reduce mains water usage by 70%, offers large saving on utility bills. Toilets and water cooling system would benefit the most from this system. The cost of installing the entire system could cost up to £2500 and saving £175 per year which results payback time of 15 years. This is a worthwhile investment to have in the ship building.

5.4.5 Security System
Purpose
As with any building, security plays an essential part in the design. But as the concept for
this building is an intelligent floor plan, it is even more crucial as one of the fundamental
descriptions that encompasses an intelligent building is that it provides for its users in all
aspects of their required needs meaning it is vital that the buildings users are kept safe while
going about their business. Due to the fact that chosen location is situated on the university
premises and the function of the building making it very open, public and would be highly
used. Pair that with the one of the aims of this building was to be a highly efficient
environment, even at peak times in the day when the student population would access its
facilities, which could make it a target for vandalism, theft and more importantly an act of
terrorism because of these possible threats an advanced network of integrated security
systems must be installed to provide countermeasures to disasters as well as reduce and
prevent the possible risks/ opportunities of risk.
To ensure the safety of the students and staff on site, there will be members of staff
stationed within the building during opening hours, this would include; members of a security
team, receptionists, and maintenance/ cleaning staff, and a reduced number nearby to watch
over the building after hours which would solely be made up of security staff and caretakers.
Key card
It was decided during the preliminary development
stages that the intelligent building would use some of the
technology already incorporated throughout Plymouth
University such as the student cards that are used for
attendance, printing and to gain access to the library
would also be suitable to use in the intelligent buildings
design also.
It was essential that a key card system was established
within the building, with staff and student cards
programmed with a tier system, for example the staff
tiers could be broken down into lectures, maintenance,
security and administrative staff, that gives the user
access to specific rooms depending upon what tier they
are, it would also track them throughout the building by
recording what rooms the owner of the card scanned to enter or exit and sending a message
to the site’s server room (e.g. [time stamp] [card number] [card tier] entered/exited [room])
but just like other already existing student cards it would have addition purposes like signing
into computers, access to printers and other onsite technologies and monitoring attendance
in the site’s lecture halls.
Each tier of card would be programmed with a list of zones within the building that its owner
would be granted access to. Some areas of the building would be restricted to certain tiers,
such as people in the possession of a student key card could not access maintenance

cupboards etc. Whereas, a member of the maintenance staff with maintenance tier key card
would be able to enter the maintenance cupboards.
The key cards will be using a traditional system of a magnetic “swipe” strip along the back as
well as a photo, barcode, a tier representative colored stripe running along one edge and
printed information on the front. However with the advancement of technology soon this
system would most likely be upgraded to an RFID (Radio-frequency Identification) tagging
system, this would not change the way the card functioned.
The way the cards will work, is that once the card is swiped or scanned by a reader, located
next to the door or on the machine, the information that has been programmed on card is
sequenced and read. The access control system located within server room will check the
information presented by the card and confer whether the door is opened/ machinery being
accessed is present on the list of accessible objects to that individual then it will grant them
access. However, if the object trying to be accessed isn’t on the list, the computer will reject
the command and no signal will be sent to the door meaning that it won’t open.
There are many benefits to using this method of security. The cards are waterproof so they
do not suffer from getting wet, they are also less prone to malfunction; therefore, not causing
so many inconveniences for the buildings users.
Security Doors
All doors will consist of a steel frame as well as a metal mess set within the body of the door
and a synthetic non-flammable plastic to ensure strong doors that are lightweight but also
function as a fire door. They will also be held in a metal door frame with heavy duty hinges to
prevent buckling from impact or heat. The door will be kept closed by electronic magnetic
locks. This helps to keep unauthorised individuals out of restricted areas, as the door will
only be released if the appropriate tier of key card is scanned. In the event of a fire all locks
throughout the building, will be released allowing all doors to
be freely accessed by anyone in the building.
Surveillance
Surveillance is another critical system required within an
intelligent building. A closed circuit television (CCTV) system
will be fitted to provide visual evidential security to all those
visiting within the building, as well as allowing security to
monitor multiple zones from one room.
There is a multitude of advantages to having surveillance
located around the buildings premises, such as it could
potentially reduce the likelihood of crime within and around
the building and all areas covered by CCTV, which would
hopefully give the feeling of a safe environment. Another
benefit is that if a crime does occur the CCTV cameras will aid in any situations where
suspicious behaviour is occurring or evidence is required.
Due to the scale of the building there will be a number of cameras situated around the
building, collecting footage. The system will consist of internal and external cameras. The

internal cameras will be connected to low voltage power supplies to allow them to run 24/7
without fear of being a drain on the buildings power supply. The power supply units will be
specific to each floor and then the separate systems will be connected to the main control
centre allowing the video footage to be recorded and viewed.
Whereas the external cameras have a motion tracking function as well as being motion
sensitive, meaning they will only activate when movement occurs, then they will follow the
motion until it goes out of range.
All the cameras fitted within this building will be using P.T.Z. (pan, tilt or zoom) dome
cameras. This will allow staff to track intruders or monitor suspicious behavior, as these
cameras are able to move vertically, horizontally and zoom. Each one of these CCTV units
will be sending information directly to the buildings control center without the need of
additional cameras. External cameras will require an infrared (IR) function to cope with
limited light between dusk and dawn. All cameras internal and external with have a backup
power source in case of a power cut.
CCTV cameras will have to be place strategically around the site to maximize observation
and it is critical that no areas are un-monitored expect the offices on the upper levels.
As there is going to be multiple camera set ups on different loops, monitoring all areas of the
buildings and grounds, however it’s not possible for someone to be viewing all the captured
footage whether it’s live feed or captured footage at the same time.
There are several ways to overcome this problem. One is by heavily controlling the rate at
which footage is captured, another is viewing it on a multi-screen in the control room to
choose which specific camera they want to view, there is also the stockpiling of footage for
use in a later on but the main solution to this is have the cameras cycle through a loop
spending 10 seconds on each camera and making sure the cameras are only on when
needed and not running unnecessarily.
Security shutters
As the library is open 24 hours a day, 7
days a week, 365.25 days a year, the
building will not also be open to the same
length of time as this seemed inefficient
instead a 6am-10pm open time slot, 7 days
a week, only during term time was deemed
more appropriate in order to support the
other university buildings instead of making
them obsolete. However certain zones
within the building will shut down at
different times to save energy, for example lecture periods start at 9am and end by 6pm so
the lecture theatres will be open between the periods of 8am – 7:30pm. Once areas are
closed industrial rolling security shutters will be lowed over the doors to seal them off and will
only lift just before it is time for the lecture period to begin.

Tannoys & intercoms
Tannoys & intercoms will also be installed allowing staff to view
and talk to the occupants of the building. Tannoys would be
used to inform everyone within the building/ on a specific floor
or within a certain zone of events. Whereas intercoms would be
used identify personnel before they are given access to the
restricted areas of building. There will also be an intercom
installed to allow conversations within the building between
staff.
Control centre/ Security office
Located on site will be a small secure office for members of security, it will be positioned
next to the server room and will house the surveillance station.
Intruder detection
Intruder detection is a key factor in any security system. As
it’s not possible to manually patrol the corridors at all hours
of the day, infrared motion sensors will be fitted in all rooms
that as well as working to turn on lights and sense when to
turn them off, and when the room has been locked, will also
function as a way of triggering alarms that will alert the
university security and the local law enforcement. Doors
and windows will be fitted with be alarmed and have
electromagnetic locks that activate when the room is not in
use, so that entry is broken, security will be notified that
someone has gained unauthorized access.
Flood lights with infrared sensors will also be fitted around
the outside of the building to light up poorly lit areas when
motion occurs in order to detect if anyone is in areas where they aren’t allowed to be.
Personal safety
Personal safety is a passive self-security set up in order to protect the buildings users from
accidents, mishaps or self-harm, although it isn’t extremely crucial as it’s a passive system it
is still a nice touch to emphasise a safe working environment. The building will use the latest
in construction materials, in this case high specification safety glass designed to be anti-
shatter without the use of a pin hammer applied to the corner of the frame. The windows in
the building will be anti-suicide windows meaning that they are small openings located on

capacity to prevent people from falling out of them.
There will be a first aid station on site to provide medical support to those who injury
themselves on site. Action plans will also be implemented and carried out rigorously to
prepare for any eventuality that may arise.
Furniture in the building will have a curved design, such as rounded edges on tables to
prevent injury. Anti-slip material strips will be place outside all exits, on all fire escapes and
on all stairs to prevent accidents in the wet.
Light emitting diode (LED) displays stall be set up all over the site to keep the buildings
users of what’s going on in their university as well as the community (like a rolling notice
board), but in the event of an emergency can be overridden to provide useful information in
the event a fire etc. because of the application each one needs to be wired into a back-up
power supply (the same as CCTV).

5.4.6 Fire Systems
Purpose
The Fire System in ‘The Ship’ university building will have to comply with British Standards
BS5839, Meaning that the system has to protect the occupants of a building from the
occurrence of a fire. This system has to be certified before occupants can use this building.
The system has many roles to play in keeping occupants safe from any fires, which may
occur in the building. It has to firstly alert all occupants about the fire and allow them to leave
the building safely, as well as preventing any spreading of fire or smoke. The system also
has to keep the buildings damage to a minimum.
Fire System Design
The design will all comply with BS5839, as this states there must be a minimum amount of
fire detectors, fire panels, alarms, call points, fire extinguishers, sprinklers/shutters and fire
doors. These will all be correctly fitted and placed at correct heights and distances apart so
that the system will conform to all regulations. There will be detailed floor plans that will
illustrate how much equipment will be used later on in this section.
Fire Detectors System As detectors are the first sign of a fire occurring, these will be placed across the whole building. However, there will need to be both smoke and heat detectors used in ‘The Ship’. This choice was made due to the fact that smoke detectors can be located in all offices, group study areas and the whole bottom floor. Yet, in the café there will need to be heat detectors instead, as the hot beverage or cooking appliances may result in smoke, leading to false alarms.
The smoke detectors that will be
used are Apollo XP95 Optical
Smoke Detector (Addressable),
which are priced at £28.79 per unit
and are approved by the British
Standards of fire safety and
regulations. This optical smoke
detector is part of the Apollo Series
65 range. When smoke enters the
chamber it causes an LED light
pulse to scatter, which causes the
detector to change to the alarm
state. (Safelincs, 2015). The
sensing element will be in between 25-600mm below the ceiling to conform to BS5839, as
shown in figure 1. (Apollo, 2013, pp.4)
Figure 33 Apollo, 2013. Available at: http://www.apollo-fire.co.uk/media/57203/bs-guide-final-locked.pdf, pp.4)
Group 4: Intelligent building
29
The smoke detectors will also have to be positioned correctly. They have a maximum range
(radius) of 7.5m from the detector, and have coverage of 112m3. The building will have
detectors over lapped to monitor every part of the floor. (Apollo, 2013, pp.6) The coverage of
smoke detectors can be seen in figure 2, which will be implemented into this building.
The heat sensors that will be used in the café will be Apollo Discovery Heat Detector
(Addressable), which are priced at £31.91 per unit and area approved by the British
Standards of fire safety and regulations. ‘Incorporating a fixed temperature response for all
modes, the Discovery heat detector can also be configured as a rate of rise unit. The Apollo
heat detector uses a single thermistor to sense the air temperature.’ (Safelincs, 2015)
The sensing element will be in
between 25-150mm below the
ceiling to conform to BS5839, as
shown in figure 3. (Apollo, 2013,
pp.4)The heat detectors will also
have to be positioned correctly.
They have a maximum range
(radius) of 5.3m from the detector,
and have coverage of 56.3m3. The
building will have detectors over
lapped to monitor every part of the
café. (Apollo, 2013, pp.6) The
coverage of these sensors can be
seen in figure 4.

Fire Panel Systems
The university building will have an automated fire control system, so when an alarm is
triggered it will identify the location, close vents, open fire doors and any other actions
required. An addressable fire alarm panel will control this, which use an intelligent system
that identifies the exact detector that
has been activated, so the precise
location of the fire will be known.
A ‘XFP Addressable Two Loop Panel’
will be used in the building, which is
£743.99 per unit. This also fully
complies with EN54 standards.
(Safelincs, 2015)

Group 4: Intelligent building

Fire Alarm Systems
The fire alarms will be evenly spread across all floors and coincide with BS5839 fire safety
regulations. As shown in figure 5, ‘the minimum sound level of a sounder device should be
65dB(A) or 5dB(A) above a background noise (if lasting more than 30 seconds) and at a
frequency between 500Hz and 1000Hz. The maximum sound level should not exceed
120dB(A).’ (Cooper Lighting and Safety Ltd, 2002) The alarms used will be Apollo XP95
Open Area Weatherproof Sounder, which is designed to work with the XFP addressable fire
alarm panels. It has a nominal sound output of 100dB and is priced at £39.59 per unit.
(Safelincs, 2015)
Manual Call Points
Manual call points will be on every floor of the building and
‘are required at all exits to the open air-whether or not the
exits are specifically designed to be fire exits unless, for
example, the exits lead to an enclosed courtyard from which
there is no escape.’ (Apollo, 2013, pp.17) They are there so
occupants can manually set off, an alarm, before sensors
automatically trigger it. Also, the call point will be positioned
1.4m from floor level to comply with BS5839 regulations.
They will also be located so no person has to travel more
than 45m to reach the call point. (Apollo, 2013, pp.12) The
Apollo Discovery Manual Call Point with Isolator (Figure 7)
will be used in the building, which is priced at £33.59 per
unit. (Safelincs, 2015)

Fire Extinguishers System
The building will have fire extinguishers available to all occupants of the building to address
any small fires that may occur, without the need to use any building systems such as
sprinklers. Figure 7 below shows the different types available, the building will have
appropriately placed extinguishers
where necessary.
The building will consist mainly of dry
powder extinguishers as they cover
almost all fire types. However, in the
café there will be wet chemical
extinguishers as well, due to there
being oil and fat in the cooking
facilities.
A 9-litre extinguisher costs:
(Safelincs, 2015):
Water: £25.19
Foam: £35.99
Dry Powder: £35.75
L2: £275.51 (N/A)
CO2 Gas: £83.39 (5 Litre)
Wet Chemical: £104.15 (6 Litre)
Fire doors/exits System
Due to the open plan nature of the building, the number of doors inside is low. However,
there will be fire doors for control rooms and any other rooms that require them. The
specially treated doors help them to burn for longer and suffocate fires by stopping the
airflow to them. This all helps to increase the time that occupants have to leave the building
and give fire longer to fight it. The standard FD30 fire doors that will be used in this building
offer 30 minutes of fire protection and are priced at £75.59 per door (Safelincs, 2015), the
fire exits in the building will be marked by an emergency exit sign above the door, to show
the location of any fire exit near to an occupant of the building.

Ventilation System
There will be a ventilation system in the building to control airflow within the building. This
can also be used within the fire system, as when a fire is detected the ventilation system can
stop airflow around the building. Resulting in fires being suffocated, as they are given no
fresh oxygen to keep the fire burning, and the spread of fire is greatly reduced

5.4.7 Sustainable Energy - Solar Hydrogen systems
Purpose
The Ship will incorporate a solar- hydrogen energy system to meet the electrical and thermal needs of the building services. This system will fall in line with the Plymouth low carbon city target by being 90-98 Percent renewable (Department of Energy & Climate Change (DECC), 2013). When hydrogen is used as a fuel the only bi- products are water, heat and electricity; making this system carbon neutral; an example The Sir Samuel Griffith Building (AUS). (Chris Menictas and Skyllas-Kazacos, 2014)
Considerations
Due to the useful floor space being
11066.4m2 a dedicated control
facility on the First Floor will house
automatic electricity and gas meter
reading. (Portal and Government,
2014). the output of the renewable
energy system will be separately
monitored and calculate the energy
usage to the Building Management
System (BMS). (Portal and
Government, 2014) Ensure that
Solar availability of solar energy
year round in Plymouth being
between 2.5-19 MJ/m^2(Met Office
(2014)(Figure 41)
Stage 1 – Solar
The system begins with photovoltaic array on the roof and
linear sides Figure 42 of the building that face south and
south west. These locations have the least amount of
shadow cover from surrounding buildings such as Rolle and
Babbage; these features increase the amount of panels
exposed to the sun throughout the day [Figure 43 & 44].

£ 298.7 (Swithenbanks Alternative Energy Ltd, 2014). Total panels are 1363 this translates
to a 258 Kw solar array. Monocrystalline panels have the highest efficiency 6-9 /1 KWp per
meter 2. Although they have a high cost they have an efficient uses of small available space.

A (SOEC) will use 30% of the solar energy provided to electrochemically split water into hydrogen and oxygen. 6 Redox Cubes 25 KW fuel cells will be used in reverse operation. (Tao and Virkar, 2006) (Figure 47)
During high insolation and hydrogen production months (May- September) the excess hydrogen produced will be stored long term to supplement the hydrogen demand for the fuel cells in the low insolation months (Nov - March). The Redox Cubes cost $1000/KW (Clark, 2013).
Group 4: Intelligent building

Rain water collected from the roof top can be in the system. This use of free water reduces
water consumption from water service provider.
Water produced from the fuel cell 22 kg per hour can also be condensed stored and recycled
for the electrolysis process. (Appendix for calculations)
Stage 3 - Fuel Cell
When the fuel cell is ran off of hydrogen it is 100% green, as there are no greenhouse
gasses produced during the reaction. This was a major deciding factor for a sustainable
energy production approach as the only by products are water vapour, electricity and heat.
Redox Cube (80 KW) in fuel cell mode will be used to convert the stored hydrogen and air
into electrical power and heat. During operation heat (approx. 3333KW) is released, this heat
was decided to be utilized in the heating, climate control and ventilation systems in the
building.
During the operational reaction the fuel cell reaction is exothermic (Heat is released), by
capturing the heat generated overall system efficiency increase from 45%-60% to 80% -
85%, this heat was decided to be utilized in the heating, climate control and ventilation
systems in the building. (Messenger, Vent and Venter, 1999).

Storage is one of the main components of this system; as peak energy production will not
coincide with the time periods in which the energy is needed (Figure 50).
Battery Storage for the Ship
The Ship will demonstrate the storage of solar energy in batteries and hydrogen. Battery
storage would be used for ‘load shifting’. The Panasonic DCB-104E (27 KWh) module was
chosen due to its high energy density per volume; high energy conversion efficiencies (95%)
(Appendix. Fig 25) and included battery management system (BMU). This BMU will be
linked to the building’s management system that will smooth out energy demand at peak
usage by releasing stored energy during peak demand, reducing grid consumption and peak
rates (Clements-Croome, 2004).The cost of 1500 € (Panasonic Corporation, 2012)

Hydrogen Storage
Choosing a hydrogen storage medium safety and volumetric density is a major concern therefore metal hydride was chosen as the storage medium as the risk of explosion is improbable. Metal Hydride(Magnesium Hydride) has one of the highest volumetric weight of 7.6%(135 Kg H2 /m3)(Figure 53) of hydrogen (Ohta, 1979) [21] at a relatively low cost (eg Magnesium hydride) that doesn’t need any energy input in order to store the fuel like liquid storage. The system will need 150 Kg of hydride (Tanks) at a cost of £36.20/ 10g (Sigma-Aldrich Co. 2015) to store hydrogen for a 3 month period of low sunlight and clowd cover throughout the daytime.
Risk Assessment:
Located in the Appendices is the full risk assessment for the project. The risk assessment
outlines all the potential risks before, during and after construction of the building.
Building Material:
As the design specification stated that the project that it had to fit in with the surrounding
buildings. The building managers decided to model the building after Plymouth University’s
buildings “Roland Levinsky & the House”. Using the same construction technique and
aesthetic design along with the same material composition of a reinforced concrete frame
with an outer shell made of copper panelling.

5.4.8 Space Saving
A key concept of an ‘Intelligent building’ is its functionality and ability to utilise all available
space in an intelligent manor, this has been done in varying ways within the university
building by using clever space efficiency techniques, whilst maximising usable working
space. Such as folding ‘curtain’ walls both in the lecture theatres but also in the smaller
study rooms, these allow the actual sizes of the rooms to be changed based on the needs of
the occupiers at the time. For instance by integrating two of these retracting walls in the
lecture theatre it can be used as a single theatre or split into two or three smaller halls, as
class sizes on different courses varies greatly. In the same way the study rooms can be split
into large rooms for group study sessions or smaller rooms for individuals allowing needs to
be accommodated and to maximise effective use of space. These walls are already being
used in other areas of the university such as in Smeaton and Babbage computer rooms and
in the seminar rooms in Robbins. However they are not as yet being used on the larger scale
in lecture theatres. These retracting walls have to be custom made for the application so a
price cannot be estimated, though as they are non- load bearing walls can be made from
lightweight, relatively cheap materials. The only issue that would have to be accommodated
for would be noise between the lecture theatres so soundproofing materials may have to be
used which would increase costing.
The building also incorporates versatile furniture and fittings allowing to maximise working
space within the building with an emphasis on the third floor and within the offices. As these
are the areas in which space efficiency is crucial in order to create an open plan, clutter free
environment which would appeal to all users of the building. These include lightweight
folding chairs which are priced at £19.80 per unit (staples.co.uk, 2015) and small linking
tables priced at £24.99 per unit (Homebase.co.uk, 2015) which can be easily resituated for
use with small or large groups or individuals. Wall mounted information screens and
underfloor power sockets, shown in Figure 1 below, will also be situated around the building.
These aspects are in use in some of the newer university buildings such as Roland Levinsky
and need to be integrated into new buildings to allow students and lecturers alike to keep
connected in the modern day.
The use of glass on the exterior of the building is
similarly an important feature in regards to space
efficiency as the use of natural light creates the
effect of more spacious rooms.

7 CONCLUSIONS
In conclusion a variety of evaluating methods have been used to help choose a final design
for the intelligent building. The purpose of the building was one of the first things to be
decided. A number of possible options were considered and after evaluate the strengths and
weaknesses of each one, a design of a multi-functional university building that will provide
space for lectures theatres, open access study areas and a café was chosen.
Next, the location of the building needed to be decided. It was felt that the building would
need to be located on the university campus to allow the building to reach its maximum
potential. Unfortunately however, being a city campus, available space for the building is
very limited. Due to this reason it was decided that the best possibility option would be to
remove an existing building to create space. By removing a section of the existing Portland
Villars, which are currently only used for offices, it would provide a location that is suitable for
the new university building. However, by doing this it would mean the new university building
will also need to contain offices to replace the existing ones in the Portland Villars.
The design and image of the building is obviously extremely important and needs to fit with
the universities image. A range of possible ideas were considered but in the end the chosen
building design is a modern, aesthetically pleasing building in the shape of a ship (which will
fit with the universities marine image).
A range of systems will be installed throughout the building helping to create an intelligent
building. There will be systems installed for sound, lighting, sanitation, the environment,
energy, security and fire. Estimated price for the systems have been included.
The aims of the report have been achieved and therefore the project has been a success.
The Project has also helped develop many useful skills which will be used throughout
university and also when in an engineering career. This include: communication skills,
teamwork skills, CAD skills (e.g. SolidWorks and Google Sketchup), report righting
techniques and time management.

Electrolysis Appendix
A solid oxide electrolyser is an electrochemical device that converts water into hydrogen
fuel. It operates in the exact opposite operation as the fuel cell by utilizing solar or grid
electricity to split the water molecule into oxygen and hydrogen (fuel).Conveniently the out
put of a Photovoltaic system produces direct current which is consistent with the input needs
of the electrolyser. This means that hydrogen can be produced by simply passing current
through the water. But unlike other electrolysers SOEC operate at high temperatures(800

1999) (Tao and Virkar, 2006)
Fuel Cell Appendix
A Fuel Cell an electrochemical reactor that converts fuel and air into heat and electricity
Fuel flows over the anode and air flows over the cathode. An electrolyte (solid ()metal oxide)
layer between anode and cathode transport oxygen ions from cathode to anode. A
peripheral circuit is connected to the anode and cathode and provides the apparatus to take
power from the fuel cell to power electrical services. (Larminie and Dicks, 2000)

A Solid Oxide fuel Cell was chosen from comparing it to the other fuel cells in table 1. Solid
oxide fuel cells characteristics and advantages for building application are due to:
1. They operate at high temperature (600-1000 Deg C) and low cost catalyst nickel metal metal catalyst this makes the cost of the cell considerably lower.
2. Operational Efficiency rating of 60% 3. 85% Efficiency when both electricity and heat is utilized. 4. Versatile operation can operate off of hydrogen or back up - biogas, methane-
hydrocarbons. (Larminie and Dicks, 2000)

(Amos, 1998) Table 10 provides the factors used to estimate the capital costs associated
with hydrogen storage.
These particular numbers were used because they provided the best cost estimates over the
entire range of flows examined.
Amos, W. A. (1998) ‘Figure F.5 – Liquid hydrogen and underground storage show relatively
little increase in cost with longer storage times due to low capital costs of storage’.

Base Load: This is the amount of electricity that is required and generated at any time.
Intermediate Load: Power plants that are easier and faster to regulate are used for the task
of middle load.
Peak Load: Power demand outside of the regular daily requirement.

Construction
Injury to workers 4 2 8 Follow working protocol and procedures. All workers must wear protective gear and take care while moving around on site, as well as take the appropriate measures when working with hazardous TMM (Tools, Machinery and Materials).
Planning permission denied 5 2 10 Alterations need to be made to meet local authority’s requirements on the building’s design.
Check with building regulations before beginning construction, as well as having weekly meetings with the sites building consultant and foreman. Make sure to design the building in an eco-friendly/ conservative manner.
Delivery delays 3 3 9 Account for lateness with deliveries. Check regularly with your supplier and drivers to make sure that everything is running smoothly and if not plan a head to make sure to stay one step ahead of your material surplus.
Building movement post build 2 4 8 Monitor the building and take appropriate action.
During construction carry out safety checks to make sure the contractor is complying with everything so as to minimalise the chance of fault. Once the building has been constructed and left to stand for 2 weeks send in a team of surveyors to check for any slant.
Finance issues 3 2 6 Account for delays, loss & replacement of materials or tools and keep track of the sites manuscript.
Focus on keeping the project budget on target if not factor in expenditures to counter the cost curve when issues arise. Keep to deadlines and account for economy fluctuation of the builds timescale.
Material availability 3 3 9 Make sure suppliers are reliable. Only employ trusted and well rated suppliers from an accredited charter to ensure supply will be met with no complaints. Make sure back up suppliers are also available/ not to use rare and hard to come by materials/ that the project has more than one supplier and that they all have surplus of the chosen materials.
Unforeseen circumstances - - - These cannot be accounted for, but respond with appropriate and logical action.
-
Lazy/ Unhappy workforce 3 1 3 Make sure the contractors that are hired for the job have a strong job satisfaction rating and may have done some work for Plymouth University before or with an affiliate that you can observe first.
Make sure to provide appropriate amenities on site as well as suitably spaced rest breaks and working hours to ensure high quality productivity. Regularly visit the site in person to assess progress and always have a progression plan that can be referred to when needed.

Machinery malfunction 4 1 4 Try to plan ahead for malfunctions. Vehicles and machinery onsite must be maintained regularly, as well as being surveyed every morning before use and put away correctly at the end of a working day in order to minimalise complications.
Working restrictions 3 5 15 It is different wherever you work, but make sure to visit the sites local planning office to check what is expected of workers.
Many places have a no heavy working policy between 9am to 7pm, if the site does have to obey these restrictions do so and make sure that the sites time management is managed smoothly to make up for it.
Construction set backs 3 4 12 Give clean and concise instruction when explaining jobs to the workforce
Supply multiple copies of a detailed plan of construction in order to minimalise mistakes and ensure to label essential materials so that they can be allocated the correct place. Again a competent workforce is key.
