I am in the process of documenting LEED O&M credits for a museum that is building an addition. In this case, the historic utility bills do not reflect energy consumed in this new area of the building.
First question: Is LEED O&M the correct rating system for an addition?
Second question: How do I document this prerequisite if there are no utility bills that reflect the energy consumed in this space?

To certify under EBOM you need at least 12 months of utility data. As it is unlikely that the addition would have separate main utility meters, you can provide 12 months of sub-meter data for all energy sources for the addition, together with 12 months of main meter data and the required number (3) of utility invoices.
If you don't have sub-meters installed FOR ALL ENERGY SOURCES for the addition, then you need to install them and wait for 12 months while you collect data.
It's difficult to comment on whether O&M is the correct rating system without additional information. If this is a NEW addition, then it is likely NOT the correct rating system. If the addition has been operational for several years then it likely IS the correct rating system.
