Many people believe that improving energy efficiency requires a complete, expensive renovation. But in Canada, experienced homeowners know: even in a post-war bungalow or an old Victorian house, you can achieve significant savings – without tearing down walls or spending a fortune.
Step one – diagnosis. An energy audit, often partially subsidized by government programs, costs a few hundred dollars but provides a detailed picture of where your home is losing energy. Most common culprits: windows, doors, the attic, and the basement.
Step two – insulating the attic. If you have an attic, adding insulation is the single most cost-effective measure you can take. Adding a thick layer (16-20 inches or more) of blown-in cellulose or fiberglass can make a huge difference. Payback period: 3-5 years. Federal and provincial grants (like the Canada Greener Homes Grant) can cover a significant portion of the cost.
Step three – improving windows. If you can’t afford new windows, consider interior storm window inserts or exterior storm windows. Cost: $50–$200 per window, savings: can reduce heat loss through the window by up to 30%.
Step four – weatherstripping doors. Self-adhesive foam tape, door sweeps, and door shoes are all available at any hardware store. This is especially important for the front door and any door leading to an unheated garage or basement.
Step five – upgrading your heating system circulator pump (for hydronic systems). An old cast-iron circulator pump can use 300–500W, while a new high-efficiency model uses only 30–50W. Savings: up to 80%. Cost: $300–$800, payback: a couple of years. For forced-air systems, ensuring your furnace blower motor is efficient (ECM motor) helps too.
