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

1. 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
   6. Calculate WUI for the building based on the utility data available and floor area

Water consumption data derived from landlord-installed meters, read manually each month is acceptable.

• Table showing past years’ water data of whole-building water use
• Calculation method used to determine the 12-month average and WUI

OR

• Documentation demonstrating that the owner does not manage the utilities (e.g. lease agreement)

OR

• Narrative indicating that W3.1b is being pursued
