eSim Conferences has been the flagship event of IBPSA Canada since 2001. They have been bringing together the building performance professionals both in Canada and internationally. The delegates represent a diverse group of academics, government researchers, and industry professionals. The paper topics are equally diverse and range from renewable energy systems, occupant behaviour, daylight, and HVAC modelling, to code, practice, and policy issues. The conference consists of two days with typically over 75 peer-reviewed paper presentations and 200 delegates, as well as two days of theory and software workshops, a technical tour, a reception, and a banquet.
