Abstract

The R-2000 Home Program has been in the forefront of improvements in the energy efficiency of Canadian housing since 1981. Over the years, Natural Resources Canada (NRCan) has measured energy use and indoor air quality in R-2000 and new conventional houses to determine whether they are improving. This paper presents the results of a survey of 163 new conventional and 63 R-2000 houses. Results show that the Canadian housing continues to become more airtight and more energy efficient in all regions of the country. By comparison, R-2000 houses consume about 31% less space heating energy than new conventional housing. Monitoring results also show that the increasing airtightness has created a need for dedicated mechanical ventilation systems for preventing indoor air quality problems in conventional houses. The R-2000 houses adequately address the ventilation issues and have shown no IAQ related problems.
