MyHEAT — Technology

Technology Overview

Making energy visible

Contact MyHEAT

MyHEAT uses machine learning to create powerful, city-wide visualizations that show areas of energy loss in buildings.

MyHEAT offers aerial thermal infrared imagery across entire cities. We quickly and economically collect high-fidelity, geometrically and radiometrically correct thermal infrared (TIR) imagery of entire cities.

Our innovative and novel technology is based on 6 years of award-winning, peer-reviewed research in Urban Thermal Remote Sensing from the University of Calgary.

flight Acquisition Standards

Through a strong collaborative relationship with the sensor developer, MyHEAT exceeds industry acquisition standards, including:

  1. 2-3 days of pre-acquisition camera (bore-sight) calibrations;
  2. the use of highly accurate onboard inertial navigation and measurement systems; and,
  3. strict environmental requirements for acquisitions

Data is collected with a plane flying over a city at night. Our nighttime data collection minimizes solar effects on building temperatures. It takes three nights to collect data for a city the size of Calgary, Alberta.

For our thermal data collection, MyHEAT builds on a world-class TIR sensor that integrates key benefits of traditional wide-area format digital cameras giving industry leading data fidelity and acquisition capabilities over traditional airborne cameras.

TIR sensors do not detect temperature, rather they detect emitted long-wave thermal radiation (i.e., relative temperature); which when ‘corrected’ to kinetic temperature can be used to present heat loss data.

Collected data is then processed to reveal individual building’s heat loss details, as well as comparable energy efficiency metrics over a town or city. MyHEAT’s proprietary post-processing pipeline includes the ability to automatically correct for local changes in temperature, microclimate, and elevation.

This means all buildings are evaluated as if they were collected at a single instance in time, allowing heat loss to be compared over different dates as well as between homes, neighbourhoods, and cities.

The result is the creation of unique HEAT Maps and HEAT Ratings for all buildings across the entire city.

Heat Loss Map

keyboard_arrow_rightHEAT Maps show potential heat loss areas from a bird’s-eye view. The thermal images indicate hot spots, or heat loss, in red and cooler areas in blue.

Heat Rating

keyboard_arrow_rightHEAT Ratings offer a relative measure of how much heat a building is losing compared to others in the neighbourhood and city.
