Question #

E4.2a — Carbon Emissions Tracking

Question

Are the carbon emissions associated with whole-building energy use tracked beyond the most recent 12 months?

Applicability

Applicable to Office and Healthcare buildings

Answer

Enter:

    • 12-month kgCO2e/ft² average before Covid (2017, 2018 or 2019)
    • 12-month kgCO2e/ft² average during Covid (2020, 2021 or 2022)
    • N/A – building built during or after the year 2022

Description

Carbon emissions due to energy consumption at the building must be calculated to inform progress toward goals and identify priorities for upgrades and optimization.

Emissions vary by fuel source and electricity is regionally dependent. Emission factors should be obtained from local utility, a government source or other credible source.

Requirements

To generate the most recent whole-building greenhouse gas (GHG) emissions intensity (kgCO2e/ft²):

    1. Enter the past years’ carbon emissions data under the benchmarking section of the online portal (bomabesthub.com), direct and indirect emissions
    2. Enter the annual averages (kgCO2e/ft²) under the Answer section, from before 2020 and after 2019.
    3. If carbon emissions are 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
    4. If any spaces were excluded, provide a brief narrative describing the methodology applied
    5. For any sub-meters referenced, provide details, such as make, model, location, photo and year of installation

Documentation

    • Data Verification Checklist printed from Energy Star or a screenshot from BOMA BEST Benchmarking section showing the past years’ carbon emissions (kgCO2e/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
    • Emission factors per fuel type and reference source
