Many people who are planning to build or buy a house would like to own one that’s energy-efficient but aren’t sure how to get started. Architect Debra Rucker Coleman gives advice by offering insight into the fundamentals of passive solar design, and explains why it’s always a good idea to design homes (or select house plans) with the sun in mind.

Tell us about your background and how you became interested in passive solar design. 

I graduated from architecture school at the University of Arizona. That was in the late ’70s, so before the current green movement, but during the 1970s energy crisis.

The instructors were very sensitive to the environment. So that’s where I got the basics of passive solar design — even though it wasn’t called that and was taught as just one aspect of environmental design.



When did you start actually designing passive solar homes? 

It wasn’t until I left Arizona and started working for other firms in the East — where the climate was colder — that I realized, “They’re not even thinking about the way a building should face or about where the sun is!” It was what I perceived as the lack of attention to the sun that made me decide to go out on my own in 1985 and establish Energetic Design, the company I had when I lived in North Carolina. I was intent on making all of the buildings I designed more energy-efficient and working with the sun as much as possible.

Using Debra's book and website, I designed our own 2400 square foot passive-solar, earth-sheltered house. More information on our energy-efficient house may be found here: http://house-in-the-hill.blogspot.com

Wonderful article, we live in a passive solar house and couldn't be happier. I encourage others to chose this sustainable and green housing path. Cheers, Tracey Allen, author of Building a Passive Solar House: My Experience Shared

Of the dozens of homeplan sites we've poured through, sunplans are by far the most attractive and most energy aware. I've talked to several home designers and they are painfully unaware of many easy and efficient techniques such as passive solar and advanced framing. They just want to sketch and print a 2x4 with code insulation. It is refreshing to see someone is out there that has a clue.
