In instances where tenant data cannot be gathered, or the LEED-EBOM applicant does not have control over tenant operational practices, the project team may exclude up to 10% of the building’s gross floor area for any credit. See page xxii of the Reference Guide for further information.
For MRc2 specifically, non-participating tenants in excess of the 10% exemption must be included in the credit calculations. Project teams should assume that any tenant that does not provide data is 0% compliant with sustainable purchasing criteria. The total purchasing level of non-participating tenants must be estimated using the data collected from participating tenants. Estimated data can be extrapolated on a per-square-foot or per-occupant basis, or by using another appropriate calculation. The estimated purchasing level should then be aggregated into the data collected for the rest of the building to generate building-wide purchasing values. See the Documentation Toolkit tab and pages 264–265 of the Reference Guide for additional calculations guidance.
