An energy-efficient, renewable energy-based heating, ventilating, air-conditioning and domestic hot water heating system for houses is proposed and modeled to assess its end-use energy savings potential. The system that consists of a ground heat exchanger, ground source heat pump, in-floor radiant heating, heat recovery ventilation system, photovoltaic generation and net-metered grid storage, is modeled using the open-source building simulation software ESP-r. Potential end-use energy savings of more than 50 percent are found to be attainable when the proposed heating, ventilating and air-conditioning system is compared with a conventional system to heat common energy-efficient homes in four major climatic zones of Canada. The corresponding reduction in greenhouse gas emissions (carbon dioxide equivalent) ranges from 19 percent to close to 90 percent, depending on the types of fuels replaced.
