Haldimand Motors is North America’s largest car dealership. In order to accommodate their rapid growth, a new 64 bay service facility was needed. The building has slab floor heating connected to two 20 ton water-to-water heat pumps with a large storage tank. The heating system is fed by a horizontal loop buried in the field behind the shop. Because the building loses heat rapidly in the coldest days of winter when the large bay doors open, natural gas furnaces will turn on to give instantaneous heat in these areas.
With a conventional system there would have been no air conditioning. When temperatures get too hot in the summertime, employees are simply sent home. Since the geoexchange system also provides cooling (chilled water feeds coils connected to the heat pumps) their summer days can now be fully productive.
In addition to the operating cost savings, CleanEnergy facilitated the application for a grant from the High Performance New Construction program that helped offset the capital cost of the installation.
