Net zero homes produce as much energy as they consume. Typically, energy consumption is low and they are up to 80 per cent more energy-efficient than homes built to conventional standards.
To achieve net zero, homes must be airtight and use renewable energy, such as solar panels and battery storage. These homes maintain a comfortable consistent temperature, with minimal drafts, and require filters to ensure clean indoor air. The result is an exceptionally energy-efficient, healthy and comfortable home.
Net zero homes may include:
- Air-source heat pumps to help heat and cool your home.
- Ground source heat pump to help to heat and cool your home
- Solar panels, which generate power for lighting, heating and cooling, hot water and appliances.
- High-efficiency appliances and systems (HVAC) that reduce energy use
- Highly efficient building envelope: exterior walls, foundation, and attic are sealed and well insulated.
- Passive heat: the home is oriented to take advantage of sunlight.
Benefits of a Net Zero Home
In addition to doing your part to reduce Toronto’s greenhouse gas emissions and address the climate emergency, a net zero home will:
- lower your utility bills for years to come
- be more resilient to weather extremes, power outages, and rising energy costs
- be more comfortable due to superior heating, cooling and ventilation systems
- be healthier as a result of a filtered fresh air system that improves air quality and reduces allergens
