Calculate the Total Energy Use Intensity &
Thermal Energy Demand Intensity of Buildings or Homes

This tool helps you calculate the Total Energy Use Intensity (TEUI) & Thermal Energy Demand Intensity (TEDI) of a building or home.
Simply enter your information in the fields below then click the download button to generate a TEUI or TEDI Factsheet. Only for Ontario-based projects.
Press the tab key on your keyboard to jump to the next input field and enter values for your building or project. Default values exist to speed up the process.
