The home's LEED Platinum website states:
By implementing geothermal, photovoltaic, solar hot water, and advanced heat-recovery technologies this home has succeeded in reducing its energy consumption by more than 70% compared to a typical home. The home also makes use of rain water cisterns for irrigation of native landscaping and a vegetated roof. Rather than demolishing the existing structure on the site, the team deconstructed, it effectively diverting 98% of its material from the landfill.
That is a wonderful accomplishment! I really LOVE this beautiful home!
