Built on a modest lot in an Ann Arbor neighborhood, this duplex was the city’s first LEED® Platinum and LEED® Gold homes. Green features include Insulated Concrete Form (ICF) walls and Structural Insulated Panel (SIP) roofs with a geothermal HVAC system. With finished basements and attics the duplex creatively uses vertical space to maximize square footage.

*The HERS Index is a scoring system for a home’s energy efficiency, like an MPG sticker for a motor vehicle. HERS starts with an average home for a point of reference called the “HERS Reference Home” which is valued at a HERS Index of 100. On the other side of the spectrum, the most energy efficient, net zero energy home scores a HERS Index of 0. Each point below the benchmark of 100 represents 1% of gain in energy efficiency.
**An EUI is the energy consumed (Btu) within a building divided by its total square feet. An EUI is a relative measure of how efficient a home is, with a lower number being better.
