The Department of National Defence and the Canadian Armed Forces (DND/CAF) are seeking a large-scale, low carbon energy generation/transfer system for heating existing buildings by integrating with their current hydronic heat distribution systems. A test building has been selected in Kingston, Ontario for a Design-Build team to design and install an innovative system, in order to assess the effectiveness and the costs of these integrated technologies, with the aim of reducing the energy demand and carbon footprint of DND/CAFs infrastructure portfolio.
