On a high rise office building in NewYork City, a super efficient 1.6 mega watt custom engineered co-generation system provides peak shaving electric power, winter office heating, and summer air conditioning for the building.

This system has increased the buildings energy efficiency from a 30% to 40% range to 60% to 65%. The system will provide 60% of the building's electricity, and 65% of it's heating and cooling. The units engine exhaust and water jacket heat is harnessed into a single heat exchanger that generates hot water for the winter perimeter heating and operates an absorption chiller for summer air conditioning.
