Net Zero Homes

Net Zero Homes

Net zero homes feature on-site energy generation that is capable of producing as much power as the household uses in a year. 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. 

What is a net zero home?

A net zero home isn’t just a home with solar panels. It combines energy efficiency and on-site energy generation to produce a better home. Net zero homes are ultra-comfortable, healthy, quiet, sustainable homes that are affordable to live in.

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 Ottawa’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 
  • reduce the impact of occupants’ day-to-day life on climate and the environment. 

Net Zero vs Passive House 

Passive House is considered the most rigorous, voluntary, high performance energy-efficiency standard for homes. These houses make great candidates for net zero homes, since their low energy use is easier to offset with energy production to achieve “net-zero”.
