Through this project, Passive House Canada was able to develop a better understanding of what it would take to establishment a Zero Emissions Buildings (ZEB) Exchange in the Greater Toronto and Hamilton Area (GTHA) to support local municipalities in meeting their building-related carbon reduction and economic development objectives. Local stakeholders and organizations leading similar programs were consulted to identify potential program priorities, partners, recommended governance structures, and staff resource needs. Passive House Canada’s Concept Development Report puts forward these best practices and makes a strong case for market readiness and demand for coordinated services of a ZEB Exchange in the GTHA.
