Total Energy Use Intensity Calculator
& Sustainability Facts Label Generator

The first step is to know, and the second step is to act. This calculator helps you determine the Total Energy Use Intensity of a building or home.
Simply enter your information in the fields below then click the print button to generate a Sustainability Facts Label. Only for Ontario-based projects.
