Steps to Net Zero
Net Zero (NZ) energy homes are regular grid-tied homes that are so air-tight, well insulated, and energy efficient that they produce as much energy as they consume over the course of a year, leaving the occupants with lower energy and heating bills, and a carbon-free home.
Why Net Zero
A Net Zero home is more durable and combines advanced design and superior building systems, with on-site solar or geothermal energy production, highly insulated walls, roof, and a tight building envelope. It is designed to save energy, reduce utility costs, reduce carbon emissions, create lasting comfort and cleaner indoor air quality.
Step 1- The Envelope- How is the Home or Building “Wrapped?”
To begin, you need a tightly wrapped building. All the electrical upgrades and renewable energy systems won’t get a home or building to net zero without addressing the envelope—the windows, roof, walls (insulation) and doors that form the structure. By addressing the weak areas of the home’s envelope, you’ll will have begun the journey to net zero.
Learn about the Envelope
Get a certified EnerGuide Advisor (EA) audit. Call an EA and book an audit. CCET has a comprehensive list of the EAs located in your area on our Resource Page here. The EA’s site visit will most likely include a blower door, thermal imaging and a thorough inspection of mechanical systems. They generate a report of priorities that detail the weaknesses and strengths of the home. You will know the level of insulation, the quality of the windows and where air is entering and heat is escaping. It will be the most comprehensive way to determine the next steps needed to create a tighter envelope.
