Building Green

It is unthinkable that we can continue

to plead that green buildings are unaffordable.

Instead we must realize, and quickly, that

we can no longer afford not to build green.

-Peter Buchanan

Our home, the Earth, is an ever-changing being, continuously transforming its layers from the inner core to the outer atmosphere.  As humans, we can look back and see the Earth’s transformations over hundreds of thousands of years, or we can observe the daily changes by watching the sky.  The climate: the change of the seasons, the rise and fall of the temperature, the rain and the blue skies; these are all part of the transforming Earth.  However, in this day and age there is new major factor taking part in the Earth’s transfiguration, humans.  We as the human population are reaping the Earth of its resources and have failed to re-direct our downward course toward an unforeseeable, but decisively dismal future.  In his book Ten Shades of Green, Peter Buchanan mentions many of the warning signs pointing toward our looming “global environmental crisis”(Buchanan 10), including global warming, loss of diversity and many others.  Renowned biologist Edward O. Wilson argues that this loss of diversity is caused singlehandedly by humans.  Through our reckless misuse of resources we have altered the Earth’s carefully balance system and we are the ones who must take steps to correct it, we need to achieve a new level of sustainable living, on a global level.  To achieve this global sustainability, we need to redesign the way we live our lives and we must approach the issue from as many sides as possible.  This is no easy task, and as Buchanan says, “clearly, architecture alone cannot bring about sustainability”(Buchanan 12).   However, there are many aspects to the way we live our lives that can be influenced by architecture and through careful planning and design, architectural changes may have a larger global impact then immediately evident.

One of the main considerations when designing environmentally sustainable or green buildings is the amount of energy the building consumes.  Most buildings in the US do not take into account the tremendous amount energy that is wasted on a daily basis.  Lighting “represents the biggest consumption of energy in built-form” closely followed by air-conditioning (Buchanan 7).  When “85% of the United State’s Energy comes form Fossil Fuels” (Ristinen) it is easy to see how unsustainable the built environment can be.  This is why it is imperative that buildings are designed with the environment in mind and in a way designed with the environment as a model.

Vertical Garden by  Patrick Blanc – A good example of designing with the environment.

The environment is a living system.  If buildings are designed like living systems, they may be able to achieve a higher level of sustainability.  Buchanan believes that “Sustainability implies long-term viability” (Buchanan 11).  This long-term viability is similar to the idea of resilience, where a system should be able to hold its own and adapt to changes.  When buildings are designed with long-term viability, they should be able to adapt and sustain themselves.  I think a building can be designed with long-term viability when it is created as a livable space, regardless of the buildings actual use.  When I say livable space, I am referring to space that is connected to the outdoors, a space with nature and natural light, a space that is integrated with the environment.  “A major element of green architecture should be not just to work with and be gentle to nature, but also to make conspicuously visible its workings and cycles” (Buchanan 9).  Not only should the workings of a building be evident, but buildings should be porous structures that allow people to see the environment and even interact with it.

A great example of a space like this is the Lumenhaus project.  This pavilion was designed to be not only permeable to, but to actually automatically interacted with the environment.  Further more, the as hinted at by the name, the Lumenhaus is powered entirely by the sun.

Lumenhaus Permeable Facade – This facade moves with the sun shading the house differently throughout the day.  As the seasons change, different amounts of sunlight enter the house be cause the spherical  cuts in the metal are modeled after the path of the sun.

Sadly there are problems with solutions like the Lumenhaus.  Due to the changes in the Earth’s climate, it is nearly impossible transport design ideas around the globe.  A design that works in the dry Sierra Nevada would fail in the humid South Eastern United States.  This is the reason that design solutions are continually forming and evolving to fit a new specific issue.  One of the things I am most excited about in the future, is having to tackle some of the problems first hand, and knowing that I am taking part in creating a sustainable Earth.

Assignment 1

Sun Panorama

a) My site has approximately eleven and a half hours of sunlight on March 21st.

b) The sun strikes my site at about 9:30 am on December 21st and a little before 6 am on June 21st.

c) Because of the tree cover, my site has the most hours of direct sunlight around July 1st.

d) The sun is at an Altitude of 48 degrees and an azimuth of 250 degrees. at 3:00 pm on August 15.

e) A porch that would be warm in the winter and cool in the summer would need to face south and be placed against the tree line at the base of the hill.  This way the trees will provide shade during the summer, but lose their leaves and let the sun strike the porch throughout the winter.

f)  There are a few notable features that may influence the design of a structure on my site.  First, there is a significant gap in the trees toward the East which allows almost all of the morning light to strike the sight.  So, it may be useful to build a shading device on the eastern side of the structure or plant trees.  Then there is also hill directly south, which would be helpful when trying to shade the site during the summer.

Emerging Ideas

For my entire life I have been exposed to the outdoors.  I was raised in a plant loving family, and have been taking walks in the woods since I could be carried in a backpack.  This exposure has instilled in me an appreciation for living, growing things.  When I decided to embark on my career at the UVa School of Architecture I did not lose my love of nature and try to incorporate the natural world into all of my designs.

After two weeks in ARCH 2230, I have realized that this class will be the perfect facilitator for my thoughts and feelings on environmentally sustainable designs.   My first reading, Nick Baker’s Essay “We are all outdoor animals,” argues for precisely the type of buildings I want to design: buildings that are open to nature and allow the environment to permeate the structure.  In Cradle to Cradle, William McDonough & Michael Braungart describe a factory they designed that was at the forefront of the environmental design movement, a factory where workers wanted to be because it was such a great environment.  McDonough &  Braungart go on to say how this factory represents “only the beginnings of eco-effective design” (76).  Designs and ideas like these are exciting for me because they signify a new era of architecture, an era that I can be a part of.

In lecture we built off environmental design ideas and related them to larger complex systems like the urban fabric of the city and even larger ideas such as climate change.  One main point we hit was the idea of the ecological city, that has important qualities of complex systems: resilience and self-organization and is also self sustainable with its “energy flow as an intensified ecology,” which connected back to my interest in nature.  This discussion inspired me to think more about buildings that incorporate nature into the very fabric of the design.  One other reading from this week was also very interesting to me because it dealt with the idea of integrating natural and artificial systems.  In his piece, A Manual for Ecological Design, Yen Yeang calls this integration ecodesign.  In the next few weeks, and possibly the rest of the semester I would very much like to further explore the concepts behind ecodesign and apply them form the scale of small building details to the urban fabric of the city itself.
