The Many Lives of 210 E. Huron
A3C has maximized the use of natural light by installing skylights wherever possible. The lights are all ultra-efficient LEDs, sensor operated so that no energy is wasted. Dual-flush toilets and sensor faucets conserve water, a passive cooling system draws heat out through two "solar chimneys," and when heating or air-conditioning is needed, it comes from a geothermal heating and cooling system whose pipes are buried under the alley in back.
To minimize remodeling waste, doors were shuffled from one place to another, and walnut panels removed from the front area went into offices. When the firm used new materials, they chose-whenever possible-either recycled or rapidly renewable ones, such as cork and bamboo. The building has insulation made from old blue jeans, rugs woven from the fiber left at the ends of spools, and wallpaper that's really paper. When the chairs wear out, the manufacturer will take them back and rebuild them. Although most of these details are invisible in the finished building, they've earned 210 East Huron a LEED-CI Gold Certificate from the U.S. Green Building Council-the first downtown Ann Arbor building to be so honored.
The part of the greening anyone can enjoy is a rooftop garden, as aesthetically pleasing as it is earth friendly. Although the post-and-beam construction of the building was strong enough to hold the garden, the roof wasn't, so A3C's architects had to add steel beams. They are experimenting with three types of plantings-meadow, arctic ground cover, and a more cultivated, parklike look.
