A new headquarters building in Milford, near Cincinnati, is serving as a model on how to design and construct affordable zero-energy buildings (ZEB) of the future. Melink Corporation, which builds commercial HVAC systems, is using the sun and rainwater for heating and cooling.
The main energy source is the sun, for lighting and generating electricity. The HVAC system uses a rainwater cistern along with an air-source and ground-source heat pump. Windows and doors will have a special glazing to conserve energy.
Employees are going green also. Sixty-one percent of them drive an electric car or hybrid.
