I’m in DC this week. Yesterday, while walking across the National Mall between meetings at DOE and EPA, I saw some of the set up for the homes competing in DOE’s Solar Decathalon. While these are small demonstration projects, they offer a chance to showcase effective technology and for teams to try out new approaches. One thing that was interesting is that a lot of the projects use technologies and practices identical to or similar to what GreenHomes uses in existing homes today. I think what it comes down to is that good approaches make sense whether you’re talking new construction, or retofitting existing homes. While you can visit the Solar Decathlon site for more images as set up is completed, here are a few early peaks.
