Net Zero Energy Buildings
A sustainable global energy system will be built on the shoulders of energy efficiency.
There are many forms of renewable energy. Using renewable energy powers a sustainable future.
New technologies and enhanced materials are taking building plans to smart design.
What is a net zero energy building?
A Net Zero Energy (NZE) building is a building for which the amount of energy provided by on-site renewable energy sources is equal to the amount of energy consumed by the building, over the course of one year.
Net zero is arriving soon to canada!
The Government of Canada will work with the provinces and territories to develop a “net-zero energy ready” model building code, with the goal that provinces and territories adopt it by 2030.
The Government of Canad will also work with the provinces and territories to develop a retrofit code for existing buildings and work towards energy labeling to support retrofits. A code for existing buildings will help guide energy efficiency improvements that can be made when Canadians renovate their homes and buildings. In 2030, 75 percent of Canada’s buildings will be buildings standing today, so we must work to improve their energy efficiency.
How to convert to a Net Zero Energy building?
Preparing an energy model
First, get an energy model done for your home to prioritize the stages of your project. This is critical because it tells you how much insulation you need, how much of a difference windows make, what size of heating system you require and what size of solar system is needed to power your home.
Tightening building envelope
No matter how old your home is, it was probably not built tightly enough for maximum comfort and efficiency. This means that your home’s windows, floors, attics, ducts, crawlspaces, and building envelope could be leaking your conditioned air outside. it simply means adding insulation, air sealing, and efficient windows.
Upgrading mechanical system
As your furnace and water heater wear out, replace them with electric heat pump models (furnace and water heater) and add a heat recovery ventilator to provide pre-warmed fresh air in your tightly sealed home.
Add a solar system
Installing solar panels can decrease your household’s carbon footprint. You should add a solar array that is sized big enough to provide all of your electricity needs, which now includes your heating and hot water systems.
