The Ontario Association of Architects has launched a new building energy usage calculator designed for use by both Ontario architects and the general public.

The new Total Energy Usage Intensity (TEUI) 2.0 calculator supplements the original TEUI 1.0 and is intended for larger Part 3 buildings as opposed to the smaller Part 9 buildings that were targeted by the first calculator.

TEUI 2.0 has the capacity to include embodied carbon, building statistics and air quality conditions and the ability to evaluate a proposed building against code compliance requirements.

The calculators were developed as the OAA fulfills its five-year strategic plan, which is focused on climate action.

“Part of our commitment to the climate challenge is to try to empower members as well as members of the public to engage with this very serious climate crisis that we have right now,” explained OAA president Settimo Vilardi. “So part of the commitment was to look at developing these tools.”
