The Lion Factory Apartments now occupied!  Natural Systems Engineering designed the vertical ground loop heat exchanger to heat and cool, and provide domestic hot water for this former factory converted to a 150 unit apartment building in Troy, New York in 2024.  The ground loop consists of ninety closed loop wells drilled to 450 ft in depth. 

At the time this was the largest ground source heat pump system completed under National Grid’s Clean Heat Program.  Very thankful to U.W. Marx and Regan Development for the opportunity to work on this project!
