The installation of a ground source heat pump (geothermal) HVAC system designed by NSE in 2024 was completed in May 2025 with our partners EMM Heating Services (Lowville, NY) and Wood Well Drilling (Star Lake, NY). The heat pump is a Energy Catalyst hybrid system that provides air conditioning and hot water heat for a hydronic distribution system, served by a 320 ft closed loop geothermal well.
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!
