Design and Construction of an Eco-House
This material is replicated on a number of sites as part of the SERC Pedagogic Service Project
Context for Use
"It's not just a house, it's an educational endeavor." -Professor Gary Wagenbach
This interdisciplinary course is a collaborative multi-year project that connects to other courses and independent study projects on campus.
Collaborative course:The Environment and Technology Studies program and Carleton College's Facilities Management collaborated on this course. A biology faculty member and the Director of Facilities Management and Planning co-taught the course. Supplemental funding for the course was provide by Facilities Management, as over the years, the course will design a new building on campus.
A multi-disciplinary course: Students from many different departments and with a broad range of environmental awareness and background took part in the class.
A multi-year project:
- The first year class studied building envelopes: The students tested insulation, earth, cordwood, and strawbale for insulative properties and conducted a life-cycle analysis of these building materials.
- The second year's students studied natural flows of energy, both heating and power.
- In the forthcoming year of the project, students will study natural ecosystem processes especially those that apply to the waste stream from human habitation, including living machines.
In one to two years, the ecohouse will be built on campus, utilizing the student research.
This course connects with other student projects and courses:
- Prairie Roof Independent Study: Four students designed and built a prairie roof demonstration on the walkway between Olin and Mudd Halls on campus.
- Food and Agriculture Class: Students wrote research papers advising the future students about agriculture and food choices for the upcoming house.
- Biology of Diseases Class: Advised future students on the possible pathogens that they should be aware of when living in the house.
Course Size: 24 students maximum
Teaching Notes and Tips
- Collaboration is crucial. One faculty member and the head of facilities management co-taught this course. They relied heavily on a campus machinist for the hands-on part of the class as well as outside consultants.
- Go with the passions of the players. This course was designed because of the particular interests of the collaborators.
- Tie the course with the particular needs of the campus. This course used a client/consultant model. The college planned to build a student house; the students are acting like the college's consultants.
- Use trained teaching assistants for software help. The outside consultants trained teaching assistants on the software packages, Sketch Up and Energy 10. The teaching assistants were available to help students with using the software.
- Manipulating materials is not trivial. Enough structure is needed for the project to be accomplished safety in a student's timeframe. The collaborating machinist was crucial for this effort.
- Connecting the world of ideas to the hands-on lab is very important. Working on a real-world, hands-on project was new for the students and they responded positively.
