Question #
E4.2 — Carbon Emissions Tracking
Question
Are the carbon emissions associated with whole-building energy use tracked beyond the most recent 12 months?
Applicability
Office, Healthcare, Multi-Unit Residential Buildings, Universal
Owner/landlord occupied building
Tenant occupied building – Owner has access to utility data
Answer & Scoring
- Yes = 4 points
Enter:
-
- 12-month kgCO2e/ft² average before Covid (2017, 2018 or 2019)
- 12-month kgCO2e/ft² average during Covid (2020, 2021 or 2022)
- No = 0 points
- Not Applicable – Tenant occupied building: Owner/Landlord does not have access to utility data OR Building built during or after the year 2022 = 0/0 points
Requirements
To generate the most recent whole-building greenhouse gas (GHG) emissions intensity (kgCO2e/ft²):
- Enter the past years’ carbon emissions (direct and indirect) data under the benchmarking section of the online hub (com)
- Enter the annual averages (kgCO2e/ft²) under the Answer section, from before 2020 and after 2019
- 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
- If any spaces were excluded, provide a brief narrative describing the methodology applied
- For any sub-meters referenced, provide details, such as make, model, location, photo and year of installation
- Calculate GHG emissions intensity for the building based on the utility data available, direct and indirect emission factors in the region, systems controlled by the owner/landlord and floor area.
OR
- Documentation demonstrating that the building was built during or after the year 2022
ENERGY STAR defines greenhouse gas (GHG) emissions as follows: https://portfoliomanager.energystar.gov/pm/glossary#GHGemissions
Documentation
Provide all of the following:
- 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
- Greenhouse gas (GHG) emissions intensity calculations
OR
- Documentation demonstrating that the building was built during or after the year 2022
Suggested Lead
In-house, with third-party support
Value
- The COVID-19 pandemic had a significant effect on building carbon emissions
- Analyze whole-building carbon emissions to better understand their carbon emissions before and after the COVID-19 pandemic
- Determine how carbon emissions have changed since the pandemic to assess if the building is on track to achieve their carbon reduction goals
RELATED Question:
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.
