Question #

W3.1a — Tracking Whole-Building Use

Question

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

Applicability

Applicable to Office and Healthcare buildings

Answer

Enter what is available:

    • Average Water Use Intensity (WUI), before Covid (2017 to 2019): ______ L/ft2
    • Average Water Use Intensity (WUI), during Covid (2020 to 2022): ______ L/ft2

Description

Tracking building performance ensures that the building operations and management team can identify issues and opportunities for improvement, track progress toward goals, implement corrective actions and inform larger water management strategies.

Requirements

To generate the whole building water use intensity, WUI (L/ft²):

    1. Enter whole building water-use data under the Benchmarking section of the BOMA BEST portal (bomabesthub.com) or in the Energy Star Portfolio Manager portal
    2. Enter any 12-month average WUI under the Answer section, over the 2017 to 2019 years before Covid
    3. Enter any 12-month average WUI under the Answer section, over the 2020 to 2022 years during Covid
    4. If whole-building water 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. For any sub-meters referenced, provide details, such as make, model, location, photo and year of installation

Documentation
