AI summary The 2010 New Houses Program (NH) saw increased participation due to the 2010 Nova Scotia building code raising energy efficiency standards. However, the program's impact on energy efficiency was limited, as participation was largely driven by heat pump incentives rather than overall energy efficiency goals. Free-ridership was also high among builders and homeowners.
