Greening of the British Columbia Building Code

The Province of British Columbia plans to reduce GHG emissions by at least 33 per cent below 2007 levels by 2020. As a result, all new buildings in the province must now meet progressive standards for energy and water efficiency. New, small commercial buildings and multi-unit residential buildings must meet new thermal insulation standards. New high-rise multi-unit residential buildings and large commercial and institutional buildings must meet the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 90.1-2004 standard. All new construction and renovation projects must also include ultra low-flow toilets (six litres) and other water-saving plumbing fixtures and fittings. The Province is exploring further areas of improvement, including grey-water recycling and the use of lighting sensors. Visit the B.C. Office of Housing and Construction Standards Web site to find out about the changes to the code.
