R-2000 Energy Saving

R-2000 certified homes offer attention to construction, comfort, health and environmental benefits. They are also some of the most energy efficient new homes on the market.

Here is the R-2000 Standard and its energy-saving formula:

Established Energy Targets
+ Advanced Energy-Efficient Features
= Attractive Energy Cost Savings

Here's how it works

Energy targets

Every R-2000 home must be designed and built to meet a specific “energy target”.

Local climate, energy sources and the size of the house are all factored in when defining the energy target unique for each R-2000 certified home reflecting a high energy efficiency standard.

The total amount of energy required each year for heating and hot water is determined by NRCan's energy simulation software called HOT2000TM.

Air Leakage Testing

Upon completion, every R-2000 certified home is air tightness tested. This test is carried out by an independent technician that has been certified through the R-2000 program. This verified that the construction of the home performs to the stringent air tightness requirements of the R-2000 Standard. Any problems that are identified are rectified by the builder before the house is certified.

Government Certification

R-2000 certified homes are certified by the Government of Canada. Once the home is completed and has passed all the required tests and inspections, the R-2000 certified builder applies for a certification for the new home.

An energy cost comparison

The chart below compares the average amount of energy used for space heating in houses of different ages and types, including R-2000. The comparison is based on a house that:

  • Has about 185 m2 (2000 square feet) of floor area
  • Consists of two stories plus a full basement
  • Is located in the Ottawa region
  • Has its windows equally distributed in all cardinal directions
  • Is occupied by two adults and two children (one teenager, one baby)
  • Uses about 24 kilowatt hours per day for basic lighting, kitchen appliances and entertainment equipment
  • Employs natural gas for space heating and domestic hot water
  • Maintains a winter temperature setting of 21°C on the main floor and 19°C in the basement
  • Does not employ air conditioning

The actual dollar savings in your case would depend on:

  • The local costs of your main fuel source
  • The current cost of energy
  • The number of people living in the home
  • Your lifestyle

*The Model National Energy Code of Canada for Houses (MNECH) was put in place in 1997 to determine cost-effective minimum requirements for energy efficiency in new housing. The MNECH applies to single family houses of three stories of less, and to additions of more than 10 m2.

The Model National Energy Code of Canada for Houses (MNECH) is intended to help you make energy-wise decisions during the planning and construction of new houses. It allows designers and contractors to choose the degree of energy efficiency that is appropriate for specific climates and fuel types.
