Deep Retrofits Getting to Zero
What are Net Zero and Net Zero Ready Buildings and Homes?
Net Zero homes can produce their own energy and can supply to the power grid, but also draw from the grid when necessary. Over a year, these balance out to 0, or Net Zero energy. Net Zero (NZ) homes are regular energy grid-tied homes that are so air-tight, well insulated, and energy efficient that they produce as much renewable energy as they consume over the course of a year.
According to Natural Resources Canada, NZ homes are expected to be 80% more energy efficient than a new building constructed to today’s building code minimum. They use on-site (or near-site) renewable energy systems to produce the energy they need.

Why Go Net Zero?
Savings
Zero energy homes are just like any home except better.They are regular grid-tied homes that are so air-tight, well insulated, and energy efficient that they produce as much renewable energy as they consume over the course of a year, leaving the occupants with lowered energy and heating bills, and a carbon-free home.
Future Proof
The value of Net Zero homes is incredible. Not only are they future-proof and built to stand the test of time, they also are built to higher standards than conventional new homes. A Net Zero Home is more durable – with high performance and better insulated walls, roof, and the envelope as a whole.
Comfort and Health
A zero energy home is not just a “green home” or a home with solar panels. A zero energy home combines advanced design and superior building systems with energy efficiency and on-site solar panels to produce a better home. Zero energy homes are ultra-comfortable, healthy, quiet, sustainable homes that are affordable to live in.

Building Envelope
Make sure the home is built or retrofitted with a high-quality, high R Value insulation and tight building envelope.The building envelope needs to be highly efficient for the rest of the system to work.
Efficient Systems
High-efficiency HVAC (e.g.,Air Source Heat Pumps) systems and appliances help keep energy use down. Windows can be oriented to take advantage of warmth and light from the sun, known as passive heating.
Renewables
Clean, renewable energy is the path forward for achieving a net zero building and reduces carbon emissions. A Net Zero Ready house has the ability to easily install renewables.

Set Your Goals
What are your priorities for getting to net zero? What is your timeline?
Book Your EnerGuide Audit
Your financing and retrofit recommendations depend on the site visit from your registered EnerGuide Auditor. We have a list of the certified professional auditors here
If you are applying for the 0% interest GreenerHomes Loan, you must book the site visit with the auditor prior to beginning any work in order for the cost to be covered by the Greener Homes Loan.
Contact Your Utility Providers
Your utility provider is essential to the process of retrofits. If solar will be installed, or your electrical service needs upgrading for the new systems like air source heat pumps (ASHP) then the utility can advise you and determine if eletrical infrastructure upgrades are needed and what costs there may be for electrical upgrades.
Contact Contractors
These Energy Advisors (EA) have specific Net Zero training. Visit this page for the list of Ontario EAs. After your energy advisor has provided you with the comprehensive retrofit report, it’s time to start looking for the contractors who can provide the work for your upgrades. We recommend you contact professional organizations who have vetted trades persons and contractors. CCET’s Resource page lists professional organziations and Contractor Resources.
Determine Finance Options
The cost of your home energy retrofits can be a barrier, but there is support for you. Visit CCET’s Financial Help page for a comprehensive list of Federal and Provincial programs, loans, financing and rebates available.
