Saint John Energy customers with a house in the city can access their personalized Heat Loss Score and Heat Loss Map by logging myaccount.sjenergy.com. In your account, you will see a pop-up or a blue banner at the top of the page to access the Home Heat Saver.

Unfortunately, not all Saint John Energy customers will have a Home Heat Saver profile. To be included in the program you must have:

• A Saint John Energy account online
• A typical single-family house within the Saint John city limits (not including apartments, mobile homes, town houses and commercial buildings)
• Complete data from the thermal flyover

 Houses may not have complete data from the flyover for many reasons, including vegetation covering the roof, poor quality thermal data or missing municipal data on the building. 

Data was collected at night in April 2019 using a thermal sensor attached to the bottom of an airplane. This flyover happened once and was the only time data was collected. Recent home energy upgrades or renovations (after April 2019) would not be reflected in your Heat Loss Score.

A Heat Loss Map is an aerial thermal image of a building that indicates potential heat loss areas. Red areas are losing the most heat and blue areas are losing the least.

A Heat Loss Score is a value assigned to a building that compares its heat loss to others in its neighbourhood and city. The higher the score, the higher the heat loss.

If you have a high Heat Loss Score, consider having a Home Energy Evaluation through the Total Home Energy Savings Program. This rebate program offers custom advice and up to thousands of dollars in incentives. Renting heat pumps is an eligible, energy-saving upgrade, which when combined with proper insulation, can result in significant savings on your heat loss and energy usage.

The world-class thermal sensor used to capture your homes heat loss is highly accurate to less than 0.1°C. Collected data is processed with peer-reviewed algorithms to reveal individual buildings’ heat loss details, as well as comparable energy efficiency metrics over a town or city.

Factors that can impact the Heat Loss Score can include:

• The complexity of the house, with larger, more complicated roofs typically losing more heat than smaller homes
• Obstructions on the roof, such as heavy vegetation, solar panels, patios/decks, etc.

Heat Loss Maps assign red to the hottest temperature, blue to the coolest, and use the full scale of colours for each house. This allows users to pinpoint trouble areas even if they have very low or very high heat loss.

Typically, heat loss in a garage is the result of heat escaping through the interior wall of the home into the garage or garage attic. The platform helps homeowners discover potential problem areas for further investigation and serves as an indicator, not a diagnosis.

No, neither the Heat Loss Maps nor the Heat Loss Score represent consumption. The Heat Loss Map represents potential heat loss areas within your home. It can help you identify where you may be wasting energy due to warm air escaping your home. The Heat Loss Score is not an energy efficiency rating, though it has been correlated with energy consumption. Consequently, homes with higher heat loss tend to consume more energy, while homes with low heat loss tend to consume less energy.

No, the thermal camera we use does not see through windows, roofs, or walls. Neither Saint John Energy or MyHEAT can identify any contents within the home. Read more in the Privacy Policy.
