R-2000 program

R-2000 is a Natural Resources Canada (NRCan) program that was developed in partnership with the Canadian Home Builders' Association in 1981, and formalized as a standard in 1982. Notably, the R-2000 standard is a voluntary standard to exceed building code requirements for energy efficiency, indoor air quality, and environmental responsibility.

The R-2000 program is managed by NRCan's Office of Energy Efficiency and comprises:
 * R-2000 standard - technical specifications
 * quality assurance
 * certification
 * training and licensing of builders and service providers
 * consumer information

In May 2008, the CHBA published an internal discussion paper proposing changes to the R-2000 standard so it would remain at the forefront as the reference model that influences other programs or initiatives.
