High performance, energy efficient homes
Rating high performance homes
A home's energy efficiency and performance level is measured using the EnerGuide rating system, which rates a home’s energy performance by comparing it to a code built “reference home” and is expressed in GJ/year. The lower the number, the less energy the home is estimated to use.
See our visual guide for how the different performance levels stack up.
ENERGY STAR® certified homes
An ENERGY STAR® certified home is about 20% more efficient and offers a practical and cost-effective option if you want new home that is energy efficient and provides increased comfort and health.
R-2000 homes are about 50% more efficient than a code-built home built while offering increased comfort, health and environmental advantages.
A home that achieves a 'net-zero' rating is an air-tight and well-insulated home that can generate enough renewable energy on-site to offset the amount energy the home uses over a one year period. These homes are considered up to 80% more efficient than a home built to code.
Other programs and labels
In addition to recognizing new homes that achieve high performance using the EnerGuide rating system, there are organizations that operate in certain areas within Canada with their own programs and labels.
The private not-for-profit association Built Green Canada is available in Alberta, B.C., and Ontario, and covers energy use, water conservation, indoor air quality and sustainable materials. Passive House Canada is an affiliate of the International Passive House Association and a member of the North American Passive House Network, and focuses on a building's energy efficiency and reducing its ecological footprint.
