Geothermal system helps home achieve net-zero energy usage

摘要

Vision Zero, Michigan's first net-zero energy home, is utilizing a geothermal heating and cooling system, solar thermal system for domestic hot water, photovoltaics to collect energy, and an energy recovery ventilation system to ensure clean, healthy air. Being net-zero, the house will produce as much energy as it consumes, and any extra energy not used by the house will be sold back to the power company via net metering. The home is a project designed and built by The Dow Chemical Co., Midland, Mich., and Cobblestone Homes, Saginaw, Mich.
