Multifamily housing buildings
ENERGY STAR® Portfolio Manager® is a tool used to track the energy use of 26,000 buildings in Canada. Energy benchmarking can help identify opportunities to save on energy costs and reduce environmental impact. This document provides a snapshot of the Canadian data for Multifamily Housing entered into Portfolio Manager as of December 2020.

For privacy reasons, data are not provided for provinces and territories with fewer than 20 registered buildings and/or 100,000 m2 of gross floor area. Numbers may not sum to the total indicated due to rounding. Variations from previous snapshots are possible because of changes in user entry or improved filtering, and data cleaning.

Definitions and data information
- ENERGY USE INTENSITY (EUI)
- EUI is the energy use per square metre at a property. EUI enables you to compare different size buildings.
- SITE ENERGY VERSUS SOURCE ENERGY
- There are two ways of measuring energy: at the site and at the source.
- Site
- SITE ENERGY is the simplest way to measure energy because it accounts only for the energy your property itself uses, as measured by your energy meters. The usage that appears on your utility bills is a site energy measurement.
- Source
-
SOURCE ENERGY not only measures the energy used by your property, but also accounts for energy losses incurred during the production, transmission and delivery of energy to your property, source energy is a more accurate measurement of the energy actually required to run your building.
ENERGY STAR Portfolio Manager uses source energy. This is the most equitable unit of evaluation, which enables a complete assessment of building-level energy efficiency.
For more information, see the ENERGY STAR Portfolio Manager Technical Reference: Source Energy.
Data quality
The data is self-reported and has been filtered to exclude outliers, buildings with less than a full year of consumption data, cases that are used for testing purposes, and an additional filter was applied. Variations from previous snapshots are possible because of changes in user entry, improved filtering, and data cleaning. Buildings registered in Portfolio Manager do not represent a randomly selected sample and are not the basis for the ENERGY STAR score.
