As energy-efficient homes become increasingly popular in Canada, homeowners are turning to Qualified Net Zero Builders and Renovators to achieve their Net Zero dream homes.

About 1/3 of greenhouse gases come from the buildings we use right now. 70 per cent will still be standing in 2050.We can’t reduce climate change just by building new net-zero homes. We need solutions that make the homes we live in right now net-zero to preserve a livable climate. Deep Energy Retrofits are the solution.

The Government of Canada is actively trying to reduce greenhouse gas emissions by supporting sustainable jobs and clean industrial growth, as part of its climate action plan. The 2030 Emissions Reduction Plan is key, aiming to cut emissions by 40%.

Central to this plan is the promotion of Net Zero Homes, which generate as much clean energy as they consume. These homes are more energy-efficient than typical new constructions. Net Zero homes ensure consistent temperatures preventing drafts, resulting in superior energy performance and comfort. Net Zero Ready homes share these features but lack renewable energy systems like solar panels. They are designed for easy future integration of such systems, allowing homeowners to upgrade when ready.

Net Zero homes rely on heat pumps, which provide an energy-efficient method for heating and cooling by transferring heat between locations. This significantly reduces energy consumption compared to traditional systems. The air source heat pump is the most cost-effective and efficient choice. While most heat pumps are designed for milder climates, manufacturers like Mitsubishi offer cold climate models that are ideal for Canadian winters. Any home, regardless of its age, can become energy efficient.

While modern standards focus on new homes, older homes can also be renovated for better energy performance. Enhancing existing homes’ efficiency is vital for Canada’s greenhouse gas reduction goals.

Renovating your home can increase its durability, ensuring it withstands wear and tear for years to come. Investing in energy-efficient renovations can save you money in the long run by lowering utility bills and reducing maintenance costs.

Health and safety considerations for any renovations include addressing potential hazardous substances such as asbestos, vermiculite insulation, and radon. To ensure the best results, consider hiring a professional company qualified by Net Zero Renovation through the Canadian Home Builders’ Association (CHBA). A home visitation by an Energy evaluator will need to be scheduled to assess your needs and create a customized renovation plan.

Since 2015, the CHBA Net Zero Home Labelling Program has certified more than 2,000 homes across Canada, including 52 in Ottawa. From 1990 to 2013 energy efficiency improved by 24.2 percent and saved $37.6 billion in energy, avoiding 85.4 million tonnes of greenhouse gas emissions, according to the NRC.

To achieve net-zero greenhouse gas emissions by 2050, Canada must enhance its use of wind, solar, and energy storage technologies. Doubling electricity production through decarbonization is essential, leveraging Canada’s untapped potential for low-cost wind and solar energy.
