Watch this short video featuring Ottawa resident Kyle Slinn talking about his home energy efficiency project and experience with the Better Homes Ottawa Loan Program.

I'm Kyle Slinn and I live in the Greenboro area near South Keys.

So, we decided to purchase a heat pump because our air conditioner was getting on in its years.

It was probably about 17 or 18 years old at that point.

So, we were looking around on what we wanted to do, and then we had heard from our solar panel installers.

They said: “Hey, this is great new program that just came out called the Better Homes Loan Program.”

The entire experience was great.

We felt like we had a good connection with the City when we were trying to figure out what we wanted to do.

And whenever we did have something come up, the City was here to answer our questions right away.

Video shows Kyle beside a large heat pump outside his home and focuses on the turning fan, the power cables and a pipe leading to the second floor.

So, this is a three-ton unit and what that means is it’s about how much heating and cooling this heat pump can do for a house.

So, about 1 ton is about 12,000 BTUs.

So, 3 tons is about 36,000 BTUs.

Text on screen reads: BTU = British Thermal Unit

And so normally if you have an energy audit done to your house, they’ll be able to figure out exactly how much air leakage is happening in your house and then determine how big of a unit you need.

Video shows Kyle next to a basement furnace.

Text on screen reads: Electric backup heater.

If the heat pump outside can't handle the cold that's going on in Ottawa, this will kick in and this will kind of supplement the heat that it's pulling out.

So, the heat pump actually never stops running.

It keeps going producing heat in the winter, but this just kicks in various stages, depending on how much heat it needs to push out.

Why is home energy efficiency important?

Homes and buildings produce almost half of the greenhouse gas emissions in Ottawa. To meet our target to reduce greenhouse gas emissions to zero by 2050, 98 per cent of existing homes must undergo a deep energy efficiency retrofit by 2040. That’s around 327,000 homes and works out to around 20,000 homes per year.

An energy-efficient home is healthier to live in, more resilient, more climate-friendly and reduces both money spent on energy, and energy used. Home energy retrofits also create good, local, green jobs. It’s a win-win for Ottawa.

How to apply

Applications for the Better Homes Ottawa – Loan Program are being processed by our partners EnviroCentre. Visit to get started.

A summary of the application process, along with typical processing times, is below:

Step 1: Complete a pre-retrofit EnerGuide assessment. This assessment provides a NRCan EnerGuide rating for the home and recommends improvements that are customized for the home.

Step 2: Complete the Better Homes Ottawa - Loan Program Application Form.

Step 3: If the homeowner’s Better Homes Ottawa - Loan Program Application Form meets all requirements of the program, the homeowner is issued a Notice to Proceed. Here, the homeowner receives a Better Homes Loan Program File Reference Number. This typically takes 1-2 weeks to process.

Step 4: The homeowner can apply to any rebate programs they may be eligible for and get estimates from contractor(s). Eligible costs are those that are incurred after the Notice to Proceed is issued.

Step 5: Submit your Funding Request Form. At this stage of the process, a homeowner can choose to request 30 per cent of funds upfront to cover deposits. This can take 3-5 weeks to process.

Step 6: Complete a post-retrofit EnerGuide assessment after the retrofit projects. This assessment provides an updated EnerGuide rating for the home.

Step 7: Sign the Property Owner Agreement and submit a Project Completion Report.

Step 8: The City of Ottawa provides the balance of the loan to the homeowner that they can use to pay contractor(s). This can take 3-4 weeks before you receive your final loan disbursement.

Step 9: The homeowner repays the loan over time via their property tax bill. A homeowner can choose to pay off the loan in lump sum at any point without penalty.
