We have multiple tenants in our building, some of which are nonresponsive to requests for purchasing records. Can we exclude their purchases?

The LEED-EBOM 2009 rating system offers a 10% floor area exemption option for multitenant buildings. In instances where tenant data cannot be gathered, or the 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 prerequisite or credit. See page xxii of the Reference Guide for further information.
