Efficiency Nova Scotia is Canada’s first energy efficiency utility. Through advice, education and rebates, they are helping municipalities and Indigenous communities to drive down their energy use, achieve reductions in greenhouse gases, and foster better communities for their residents and businesses. Learn how Efficiency Nova Scotia is able to promote energy savings at municipal buildings through upgrades, retrofits and new construction, in municipal operations with Onsite Energy Managers, water and wastewater utility projects, district energy and via policy with building codes and by-laws. The presentation will also explore key drivers and barriers for Nova Scotian municipalities and explain how Efficiency Nova Scotia interacts with other industry stakeholders.
