circular architecture From cradle…

circular architecture … to grave


The availability of virgin materials is decreasing fast. In such a rate that already for

some rare materials we have a few years left before we run out.

Besides the fact that we run out of new materials the harvesting of them also has

negative side effects which influence global warming, harm our ecology system and

threat our health.

The urban environment and the building practice takes up approximately 30% of the

material use.

We lost the connection to our natural environment and rely more and more to

technical solutions. Over the last years their is a rising attention to go back to a

biophilic approach with more attention to light, air and green.

Introduction



Towards a circular design architecture

In my opinion architects, advisors and builders should focus more on the closing of

cycles (materials, water, energy and ecology), creating a healthy indoor environment

and the role the building can play in harmony with it’s natural surroundings.

This circular design process asks for a new type of leader who has experience on the

closing of cycles and knows how to translate this into integral solutions together with

the design team.

Not just the adding up of the architectural idea, the building construction and

installations but a well organized concept that adds value to the location and

creates a healthy indoor environment with a minimum of energy.

Vision



My goal is to get the most ambition out of the available budget foe the project. A

sustainable design is about making choices and realizing what effect these choices

have on other topics. For instance a energyneutral building isn’t necessarily a healthy

building and a natural material like wood also could mean extra maintanace.

I always start with investigating the possibilities on all themes and discuss this with my

client. By this we can make choices and form an ambition which is realistic to the

budget. Even though not all the possibilities can be realized an optimum can be

formed between the different topics and elements can be taken into the project.

In my work I look at the following themes:

© Materials;

© Water;

© Energy;

© Biophilic design;

© Indoor health;

Approach

circular architecture Materials

Waste=Food

By closing biological circles we can save valuable natural resources. Next, when

choosing materials we look at the possibilities to create a closed circle. Natural

resources which are harvested in a good way, like fsc wood and bamboo, without

additional chemicals or VOC’s can be given back to nature and are often cheaper

because they are locally available. The added value of natural materials also

contributes to a healthier indoor climate, so building services can be designed

cheaper, for instance by using natural ventilation principles or local climatising

concepts where each user has control on the climate on his or her working place.

Upcycling

Not all materials can be used in a biological circle. For the materials which can’t be

used in a biological circle we look at the re-use of materials, for instance by designing

buildings according the IFD method (Industrial, Flexible, Demountable) All the building

components are prefabricated elements which can be re-used in another position or

for another function, so gluing and sealing is prevented. By minimizing fixed elements,

and working with light building structures our buildings can be put together in a fast

and effective way. This results into a flexible building, not only in use, but also flexible

to the future.

circular architecture Water

Living with water

The Dutch have a long relationship in their fight against water. Over the last years we

started to realize that we shouldn’t fight against, but work to live more in harmony

with the water.

A large part of the Netherlands is a Delta of 2 large European rivers and lies below sea

level. This means that not only the sea forms a threat, but also the rivers which come

from the European high lands. Almost 90% of the total population on earth lives in a

Delta area so faces the same challenges as the Dutch. Besides this climate change

also faces us with new challenges; heavy rains and longer dry periods.

This means we have to design our built environment in harmony with the water. Not

just protecting the land, but also look for possibilities to store water in periods of heavy

rains, and use it when it is dry. Solutions like wetlands and water squares provide this

storage, and green roofs reduce the amount of hard area.

From the buildings perspective we look at solutions to save water and re-use grey and

even black water so the use of clean water can be reduced.

circular architecture Energy

Efficiency/Optimize use of energy

To create integral building concept we look at the total life cycle of the building. The

first step is to optimize the use of energy in the building to make the building efficient

in use. We can have a look at the residual, sustainable installation concepts like low

temperature heating end the re-use of water, for instance by storing rain water and

use it in the building.

Effectiveness/Use renewable sources

A building always needs extra energy to function properly. If possible we will

investigate the use of renewable sources and how they can be used effectively, for

instance by use of earth warmth to heath a building or use the sun to generate

electricity. These measures will ask for extra investments which can be earned back

on the exploitation of the building.

circular architecture Biophilic design

Design by nature

What if we would design buildings where the human takes a central position? A

building with optimal use of natural daylight, a good indoor quality with fresh air and

non polluting materials, good acoustics and embedded in harmony with it’s

surroundings.

By creating green roofs and/or facades we can continue the landscape and urban

conditions into the building. This resolves in valuable space, not only for plants or

animals, but also as an added value for the users by creating a roof garden for break-

out space or an atrium as a meeting space. A green roof also creates extra insulation

and storage of water. The position of the sun and existing natural structures, like trees,

can be used to protect the building from the sun and as a result overheating. This

means mechanical ventilation or additional cooling isn’t necessary.

circular architecture Indoor health

Designing a sustainable building is more then adding sustainable solutions to a

building.

The Indoor Environment as from an Architectural and/or Environmental Psychology

perspective describes the “experience” or spatial comfort of the space under

consideration which includes aspects like: lines of sight, color, balance between day-

and artificial light, view, well being, etc.

The Indoor Environment aspects can be placed in a modified pyramid of Maslov,

beginning with protection of people against the (hostile) external environment, Indoor

Environment from a health point of view (IAQ), Indoor Environment from a thermal

comfort point of view, Indoor Environment from an Architectural Point of View, Indoor

Environment from an Environmental Psychology Point of View and finally the highest

level: the Indoor Environment as a place for Social Interaction: that what the building

is intended for.

All the aspects should work as a total and every taken measure should add to this.

My added value lies in the design of healthy and comfortable buildings which are

energy efficient. My expertise lies in the architectural design using natural elements

like daylight and green solutions. Also the use of circular concepts and the closing of

material cycles is part of my expertise. I am well experienced in translating the

sustainable design features into a sustainable business case.

By using urban surroundings and conditions for the design, and looking at factors like

orientation, influence of the sun, and making use of existing natural elements the

design can work in harmony with the environment.

My strength lies in combining knowledge in my projects and getting the best out of

the different parties involved in the design process. I am convinced that a sustainable

building can only be realized when it is the result of an integrated design approach.

Working together, communicating and staying critical at each other’s work is

essential to be successful.
