Great River Energy, a not-for-profit electric generation and transmission cooperative, has announced it is pursuing LEED (leadership in energy and environmental design) platinum level certification for its new headquarters in Maple Grove, Minn.
The company will use energy from an on-site wind turbine and roof-mounted solar photovoltaic panels. In addition, solar energy will be used to heat domestic hot water through a roof-mounted solar thermal system, Great River adds.
Other design strategies include using Arbor Lake for a geothermal heating and cooling system, using rainwater for site irrigation and the flushing of toilets, and installing elevators that use 60% less energy and require less space.
Currently, there are only 15 newly constructed LEED platinum level certified buildings worldwide, the company says. It expects the new LEED building will be move-in-ready by April of 2008.
