GREEN SPACE: An A2 ranch goes zero-carbon

A ranch house in the Geddes Heights area of Ann Arbor is being renovated in such a manner that its net energy usage will be equal to the amount of energy it generates via solar and geothermal production.

The Nautilus House, as it has been dubbed, is attacking the energy problem from all sides and, in so doing, a striking home is emerging.

The architect, Michael Klement of Architectural Resource and the builder, Doug Selby of Meadowlark Builders, found a creative and inspiring client in sculptor and homeowner Claudette Stern. Stern was interested in sustainability, not afraid of bold design and, in terms of cost, was willing to forego a new kitchen if it meant she could afford a more energy-efficient design.

In the expansion of the one-story north end of the home, a curvilinear roof was designed, which will accomplish many things: it maximizes the solar opportunity for the site, will aid in rainwater gathering and will act as a natural vent, instrumental in heating and cooling the home.

Other green aspects of the home will include geothermal heating and cooling; the use of structural panels and advanced framing techniques in construction, which will both minimize material usage and maximize the amount of insulation that can be used; and the reuse of materials such as windows.

The home will be Platinum LEED-certified as a remodel; the sixth in the nation and second in Michigan to be so recognized.

You might recall the first in Michigan: it was a home on Fourth Street that Selby and Klement collaborated on and that Green Space toured. Check out this article to learn more about it.

The home will be open to the public for a weekend in January for a "Behind the Drywall" tour; watch this space for details.
