CLEVELAND -- A nearly air-tight environmentally friendly house in Cleveland has become the first building in Ohio certified by the Passive House Institute U.S.
The nonprofit organization promotes high-performing designs to reduce energy consumption.
The initial Ohio designation went to a three-bedroom Cleveland house with thick, heavily insulated walls. It has high-tech windows and nearly air-tight construction to minimize heating and cooling costs.
Director David Beach with the GreenCityBlueLake Institute at the Cleveland Museum of Natural History tells The Plain Dealer that the demonstration project was successful.
The house passed an exam to assess energy used for heating and cooling, total energy use and air tightness.
The house was a museum attraction in 2011 and then was moved several blocks and sold.
