Assignment 4 Interim October 25, 2011

1)      SUBJECT

For Assignment 4 I chose to examine The Center for Energy Efficient Design (CEED), In Franklin County, Va. (20 minutes from my hometown, Roanoke, Va.) After attending a lecture at a church in Roanoke on this local project.  CEED is an extension of Franklin County high school, a small school in an extremely rural area of Virginia, with a goal to raise awareness and knowledge on renewable energy technologies and passivehaus design.  This building includes both a classroom and hands on laboratory where high school students study topics like hydroponics, aquaponics, and biodiesel production.  This building is not only a tool for our youth but it is also open to the public so that builders and contractors can see passivehaus systems in action, so that they can more easily apply these in their own work.

 

2)      OUTLINE OF ARGUMENT

An unbelievable amount of systems are applied to the Center for Energy Efficient  Design.  Below I have listed these.

Technologies used:

passive design

earth berming

south facing orientation

solar glazing

solar appropriate overhangs

thermal mass

geothermal energy

photovoltaics

solar water heaters

electricity-producing wind turbines

rainwater harvesting

energy-efficient appliances

daylight harvesting

cross ventilation

indoor air quality insulated shading

energy efficient landscaping

            water saving fixtures

            green roof application

For my Project I plan on focusing on the insulation used in the CEED, since that has been our main focus in the most recent class lectures.  I was intrigued by the simple drafted section image that Bill put up of a highly insulated wall that he mentioned simply came from a building standards book.  I think that exploring a detailed part of a building such as a wall or joint section will help me to get a better understanding of the actual construction techniques used in passivehaus building. So far in studio we have only built models at much smaller scales than what I plan to attempt for this project. This unfortunately forces us to edit out many layers of information that are essential for a built structure to function.  Also, by showing this in 3D I hope to be able to make the material palette and proportions a little bit more understandable and interactive to my classmates than the images that we have seen of these sections are.

4)      FINAL PRODUCT

I would like to physically model an insulation section of one of the highly insulated exterior walls of CEED, or of an eaves joint showing the two different types of insulation occurring on both the wall and roof.  This model will be at either ½”=11 or 1”=1’ scale.  In addition to this I would like to draw some diagrams similar to the one below (which is NOT of my building) showing more detailed construction drawings of what is happening at a few of the important joints of the CEED.
