As thousands of homeowners have discovered, R-2000 is the smart new home choice. R-2000 is made-in-Canada home building technology with a worldwide reputation for energy efficiency and environmental responsibility. The R-2000 Standard is a series of technical requirements for new home performance that go way beyond building codes. Every R-2000 home is built and certified to this standard. The Canadian Home Builders' Association works with Natural Resources Canada's (NRCan's) Office of Energy Efficiency which manages R-2000 on behalf of the federal government in support of R-2000 technology, builders and consumers.
