WalterFedy provided architectural and engineering services to complete schematic design, design development, contract documents, contract administration, and field review services for the installation of a ground source (geo-exchange) heat pump system to replace natural gas combustion for space heating and chiller plant operation at Conestoga College’s Cambridge campus. The project required the installation of a geothermal wellfield at a suitable location on campus, the installation of heat pump equipment that provides both heating and cooling for the building, and modifications to the existing HVAC distribution system to accommodate the heat pump system.


A 500 kW net-metered solar photovoltaic system was also installed on-site to match or exceed the annual electricity consumption of the ground-source heat pump system. This combined system will eliminate over 75% of both Scope 1 and Scope 2 Greenhouse Gas (GHG) emissions associated with operating the building heating and cooling systems.


In advance of the design, WalterFedy also performed energy and GHG analytics in preparation of a funding application for this facility.
