We need greener buildings

Posted by Michael Keating

When we talk about cutting greenhouse gas emissions we often think of coal-burning power plants, motor vehicles and aircraft. But homes and buildings are a major source. A statement from the Canadian senate says they are the source of about 17 per cent of the country’s greenhouse gas emissions, mainly from burning oil and gas to heat them. It’s been possible for years to build structures that need virtually no fossil fuels to heat them. However, many buildings leak large amounts of heat because they were built in an era when energy was cheap and builders did not want to raise the purchase price by adding more insulation and energy efficient windows and heating systems. An article on green buildings says North America still often settles for mediocrity when it comes to green buildings. Homeowners and owners of businesses appear to be heading towards a change that may become a crisis. If we are to meet our goals of greenhouse gas reductions, we have to phase out of fossil fuels, and that means most buildings will have to change their heating systems.
