This home in downtown Ann Arbor is Michigan’s first LEED® Platinum gut/rehab. Built in 1837, it was an old historic house with good bones, but suffered from several decades of deferred maintenance. An addition had been put on the house in the 1920’s, but was compromised and poorly laid out. We took the original addition off and put a new addition in it’s place to solve many of the home’s problems. This house features Not-So-Big® design principles, an ICF foundation, advanced framing, geothermal heating and cooling, and extensive use of reclaimed building materials.

*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.
