ERS Project Wins AEE 2010 Renewable Energy Award

ERS wins the Association of Energy Engineers' 2010 Region 1 Renewable Energy Project of the Year award for our Steinway & Sons rooftop solar-thermal project.

The Steinway project is the largest commercial rooftop solar-powered dual-purpose heating and cooling system of its kind in the world. It works by collecting the sun’s rays with 38 rooftop solar concentrating tracking troughs that reflect and focus the sun’s energy onto receiver tubes through which a thermal fluid circulates. The liquid is heated to 340°F and pumped to a high performance 100-ton double-effect absorption chiller that uses the superheated water to develop a chilled water supply, which is then used to provide cool air and dehumidification to help maintain the consistent environment required for Steinway’s piano manufacturing. When cooling/dehumidification is not needed, the solar hot water can be converted to steam for process or space heating purposes in the factory.
