Total Energy Use Intensity
TEUI Calculators
The OAA offers two, free online tools that complement each other and enable the profession and the public to measure the Total Energy Use Intensity (TEUI) of a building.
The TEUI Calculator (temporarily not available due to maintenance) lets you determine an existing home or building’s energy performance by entering simple data into an easy-to-use interface. Users receive instant metrics for their building’s energy performance, and get a PDF printout to show clients or other stakeholders. The tool is intended for Part 9 buildings. Check out the video below for a brief tutorial on how to use it.
TEUI 2.0 calculates the TEUI and Thermal Energy Demand Intensity (TEDI) of a building or home. Intended for Part 3 buildings, it offers intuitive drop-down menus for classification, area, compliance standards, and tiered code options. To learn more, check out the video below or on the OAA YouTube channel.
The OAA’s Design Excellence Awards also require TEUI metrics for eligibility, and these calculators make it easy to include the data.
Energy simulation or performance compliance tools do not guarantee a building will meet the proposed targeted performance due to factors beyond the control of the software application. This includes construction methods, contractor experience, user interface as well as weather and climate factors. These calculators are not intended to predict actual performance, but rather to set targets over a baseline or reference case using the same methods.
