Natural Resources Canada
Natural Resources Canada (NRCan) is the Canadian federal government department mandated with the responsible development and use of Canada’s natural resources and the competitiveness of the country’s natural resources products.
In December 2016, NRCan awarded the contract to EfficiencyOne Services to convert two existing residential new construction programs, ENERGY STARTM for New Homes (ESNH) and R-2000, into an updated EnerGuide Rating System (ERS) v15.
Using NRCan’s updated energy modeling software, HOT2000 v11, EfficiencyOne Services’ residential new construction engineer modeled homes that comply with the current ESNH and R-2000 standards to evaluate new performance metrics compatible with the new ERS and HOT2000 v11. Recommendations included setting whole house energy targets, R-2000 building envelope targets, energy target metrics, and considerations for space cooling, the use of energy efficient products and operating conditions, and how to streamline the prescriptive path to ESNH compliance.
