Energy Star

Energy Star

A new home that has earned the ENERGY STAR label has undergone a process of inspections, testing, and verification to meet strict requirements. ENERGY STAR certified homes use 15-30% less energy than typical new homes while delivering better comfort, quality, and durability.



Leadership in Energy and Environmental Design (LEED) is a rating system that is recognized as the international mark of excellence for green building in over 132 countries. Since 2002, the Canada Green Building Council (CaGBC) and LEED Canada have been redefining the buildings and communities where Canadians live, work and learn.


HERS Rating

A home energy rating involves an analysis of a home’s construction plans and onsite inspections. Based on the home’s plans, the Home Energy Rater uses an energy efficiency software package to perform an energy analysis of the home’s design. This analysis yields a projected, pre-construction HERS Index. Upon completion of the plan review, the rater will work with the builder to identify the energy efficiency improvements needed to ensure the house will meet performance guidelines.


SB-12 Energy Efficiency Compliance

SB-12 contains acceptable solutions for achieving energy efficiency compliance with Division B in the Building Code. Conformance with one of the prescriptive compliance packages of this Supplementary Standard will achieve an energy efficiency performance level that is generally equivalent to a rating of 80 or more when evaluated in accordance with the technical requirements of NRCan.
