In relation to the baseline water usage for buildings with respect to their certificate of occupancy dates, for buildings dated 1995 or later, the baseline is set at 120% of the water use that would result if all fixtures met the code requirements. This guideline is part of the LEED Operations and Maintenance Rating System's approach to evaluating water use in buildings and setting a baseline for comparison and improvement.References:LEED v5 O+M: Existing Buildings beta version

Evapotranspiration data is used in the calculation of landscape water requirements, which is a key component of the Outdoor Water Use Reduction credit under the LEED AP Operations + Maintenance (LEED AP O+M) V4.1. This credit encourages strategies that reduce outdoor water use, and using evapotranspiration data can help to more accurately estimate the water needs of the landscape, thereby reducing unnecessary water use1.
