FAQ

Your questions, answered.

  1. Why aren’t the maps for Alberta available anymore?

    Our beta test is complete, and we are using the feedback from our users, as well as implementing improved processing algorithms to deliver even better HEAT Maps and HEAT Scores for every home in Alberta. The new version will be launched in collaboration with additional organizations who are passionate about energy efficiency. Sign up (if you haven’t already done so) to get notified when it becomes available.

  2. How is the data collected?

    Data is collected using a thermal sensor attached to the bottom of an airplane. We only collect mid-wave thermal infrared energy (3-5 µm) emitted from the surface of the features (i.e., houses, roads, vegetation) composing the scene at the time of acquisition. We do not collect, or have access to, any information regarding the number of occupants in a house, their age, gender, race, income, or the occupancy status of the home. We also cannot identify any contents within the home. Read more in our Privacy Policy.

  3. When was the data collected?

    The data was collected in October 2015 for Airdrie, Calgary, Edmonton, Okotoks, Red Deer, Sherwood Park, and St. Albert. For Grande Prairie, Lethbridge, and Hamilton, the data was collected in October 2016. All data is collected after 11:00 PM in order to nullify any impact of solar loading.

  4. Is the data collected in real time?

    No, the data is not collected in real time. The HEAT Map of your house was collected at a single instance in time.

  5. Can you actually ‘see’ into my house with this data?

    The thermal camera we use does not see through windows, roofs, or walls. We currently show data with a 1m spatial resolution and a spectral (thermal) resolution of 0.05°C. This means that every pixel composing the HEAT Maps represents an area on the ground 1m x 1m in size. Read more in our Privacy Policy.

  6. Why aren’t the HEAT Map and Aerial Image aligned properly?

    Simply because they come from two different data sources. The HEAT Map is provided to you by MyHEAT, while the Aerial Image is provided through the Google Maps Static API. Basically, it’s the image of your house as seen in any version of Google Maps. We are currently working to improve this alignment.

  7. What are the ‘grey’ areas in the HEAT Map?

    The grey areas represent the raw thermal data around a home that have been processed with a smoothing (i.e. blurring) algorithm, so as to provide more focus on the detailed HEAT Map colours of your home.

  8. Why is my address different from the one I searched?

    Our map search is powered by the Google Maps API while the house addresses in our database come from multiple sources such as local governments, or through open data catalogues. In most cases, the addresses are very similar. However, the street type (e.g. Rd:Road, St:Street, Ba:Bay, etc.) may vary depending on the source.

  9. Why do most houses ‘look the same’?

    This is because the temperature difference of the roof is mapped to the full spectrum of colours shown. As a result, every home will have some blue and some red. For example, if one house has a temperature range between 7°C and 12°C degrees, the system would assign 7 the colour blue and 12 the colour red (and then distribute the rest of the colours between that range). Another house may have a temperature range between 10°C and 13°C degrees. In this case, 10 would be assigned the colour blue and 13 would be assigned the colour red.

  10. How are HEAT Scores calculated?

    HEAT Scores are individually calculated for every building based on measured roof temperature range and average, as well as the total heat loss from the building footprint. HEAT Scores allow all homes to be ranked based on their heat loss and are highly correlated with energy consumption. They are not a measure of home energy efficiency – though they are related.

  11. How accurate is the HEAT Score?

    The world-class thermal sensor used to capture your homes heat loss is highly accurate to 0.05°C. The HEAT Score is not an energy efficiency rating - though it is correlated with energy consumption. Consequently, homes with high heat loss, also tend to consume more energy, while homes with low heat loss tend to consume less energy. Factors impacting HEAT Score include: (1) the size of the house, with larger houses typically losing more heat than smaller houses, (2) how well the roof material is classified (as this affects an important thermal characteristic known as emissivity), (3) how well vegetation over roofs are classified, (4) and how well we are able to fit home boundary information (i.e., GIS building polygons) to the corresponding thermal image of the home – for which we have developed world-class patent pending technologies.

  12. Why doesn’t my house have a HEAT Score?

    If your home does not have a HEAT score, it may be due to (1) vegetation covering more than 40% of your roof, (2) missing thermal data, or (3) incorrect home boundary information (i.e., GIS building polygons).

  13. What do I do with a HEAT Score?

    The HEAT Score is an informative comparative tool that provides ranked based feedback (from low to high heat loss). It should be used in conjunction with your HEAT Map to identify potential heat loss areas in your house. Together this unique home heat loss information can be used to motivate residents to (1) reduce energy costs, (2) obtain an energy efficiency inspection, and (3) make retrofits.

  14. My house is not on the map. Why is that?

    Currently, MyHEAT is focused on single-family residences for the cities available online on our platform. If you live in a single-family residence and your house is not on the map, please send us an email so we can look into this matter.

  15. I don’t want my house shown on the map. Can I remove my house’s HEAT Map and HEAT Score from this site?

    Yes, please send us an email with your house address and we will remove it within 10 business days.

  16. My question is not listed here. How can I contact you?
