Question #

E4.1a — Energy Use Tracking


Was whole-building energy use data tracked before and during Covid?


Applicable to Office, Healthcare and Multi-Unit Residential buildings


Enter what is available:

    • Energy Star score before Covid (2017, 2018 or 2019)
    • Average Normalised Energy Use Intensity (EUI), before Covid (2017 to 2019)
    • Energy Star score during Covid (2020, 2021 or 2022)
    • Average Normalised Energy Use Intensity (EUI), during Covid (2020 to 2022)


Utility data must be tracked and monitored to provide information necessary for assessing a building’s energy consumption. This measurement will allow the team to set and track progress toward goals, implement corrective actions and inform larger strategies.


To generate the whole building energy use intensity, EUI (ekWh/ft²):

    1. Enter the past years’ whole-building energy use data under the Benchmarking section of the online portal (bomabesthub.com)
    2. Enter any 12-month average EUI under the Answer section, over the 2017 to 2019 years before Covid
    3. Enter any 12-month average EUI under the Answer section, over the 2020 to 2022 years during Covid
    4. If whole building energy use is calculated by adding data from different bills or sub-meters, provide a brief narrative describing the methodology applied. Show how the 12-month total use was calculated
    5. If any spaces were excluded, provide a brief narrative describing the methodology applied
    6. For any sub-meters referenced, provide details, such as make, model, location, photo and year of installation
    7. Indicate whether any energy is generated on-site and whether that use has been sub-metered


    • Data Verification Checklist printed from Energy Star or a screenshot from BOMA BEST Benchmarking section showing the past years’ energy use (ekWh/ft2) before 2020 and after 2019
    • Calculation method used to determine the 12-month average
    • Narrative of benchmarking methodology and sub-meter data, if available
