Utah Passive House (Mill Creek, Utah, USA)

There's a website called Our Passive House, where the owners are documenting the design and construction of the first Passive House in Utah. The owners are on Twitter @ourpassivehouse. Designed by Brach Design, Utah's first certified Passive House consultant, this energy-efficient home fits in to the context of the established neighborhood where its two-door style mirrors a look that's already common with many existing homes. When completed, the 3,000 square-foot home should show high energy performance numbers. It features passive design, photovoltaics, solar hot water, super insulation and many other design ideas.
