Sustainable Building Energy Systems (SBES) is a research group in Carleton University’s Faculty of Engineering and Design that is lead by Professor Ian Beausoleil-Morrison. We conduct experimental- and simulation-based research into a variety of topics and technologies relating to sustainable building energy systems and renewable and energy efficient technologies. Our projects often involve collaboration with Carleton University’s Human-Building Interaction Lab, Solar Energy Systems Lab, and the School of Architecture, and with researchers at other Canadian and international universities, industry, and government.
