2013 Solar Decathlon Technologies, Modelling Tools and Canadian Applications

Austin Selvig, William O’Brien, Craig G. Merrett

Abstract: The 2013 U.S. Department of Energy, Solar Decathlon (SD) competition gave post-secondary students the opportunity to design and build novel net-zero energy (NZE) houses. Energy system information was collected to find ways of designing more cost-effective NZE houses for Canadian climates. Information on the design tools, performance and affordability of the houses was also collected. The teams used a wide variety of drawing and energy modelling tools. The most prevalent technologies for heating, cooling and domestic hot water (DHW) systems included air source heat pumps (ASHPs) and solar thermal systems of various types. The most likely candidate for a Canadian cost-effective design is a SD house that has highly insulated walls, an ASHP and an instantaneous DHW system. This house performed adequately, was designed for a cold climate and had the lowest cost. However, finding the most cost-effective full scale NZE house for Canadian climates will likely require optimization.
