Question #

E3.1a — Benchmarking Energy Use

Question

What is the calculated Energy Star score for the building?

Applicability

Applicable to Office, Healthcare and MURB

Answer

Indicate which range is representative of your building’s most recent Energy Star score:

    • 90 and higher
    • 83 to <90
    • 75 to <83
    • 65 to <75
    • Lower than 65

Description

It is important to establish energy baselines to enable measurement and tracking of progress toward net zero goals.

Portfolio owners may want to benchmark their properties against other buildings within their portfolio to evaluate comparative progress and prioritize asset renewals.

Requirements

To determine the most recent Energy Star score:

    1. Enter whole building energy use data under the Benchmarking section of the BOMA BEST portal (bomabesthub.com) or in the Energy Star Portfolio Manager portal
    2. 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
    3. If any spaces were excluded, describe the methodology applied
    4. For any sub-meters referenced, provide details, such as make, model, location, photo and year of installation
    5. Indicate whether any energy is generated on-site and whether that use has been sub-metered

Documentation

    • Data Verification Checklist printed from Energy Star, or screenshot from BOMA BEST Benchmarking section showing the normalised Energy Use Intensity
    • Narrative of benchmarking methodology and sub-meter data, if available

Adapted BB3 Question

Question 01.02.01 — Do you benchmark energy performance using either BOMA BEST or ENERGY STAR Portfolio Manager portal?
