A campus is a collection of two or more buildings that act as a single property. They are generally owned and operated by the same party.
In order to be eligible for ENERGY STAR Certification, a campus of buildings must be a single, cohesive property with a single shared primary function. There are five property types that can earn ENERGY STAR certification as a campus: K-12 School, Multifamily Housing, Hospital, Hotel, and Senior Care Community. For other property types that exist as a campus (such as an office park made up of multiple office buildings, or a lot containing several warehouses), each individual building must be benchmarked and certified individually.
Metering configuration is not a factor in determining whether buildings function as a campus or not. Buildings that are separately metered may be considered a campus. And buildings that share meters may be considered individual properties (sub-metering would be required for certification in this case).
For purposes of ENERGY STAR Certification, the following are examples of properties that would not qualify as a campus:
- Two office buildings that share a central plant and are not sub-metered. Regardless of metering configuration, offices are not eligible to apply for certification as a campus. Sub-metering would be required for certification in this case.
- A K-12 School that sits on the same property as the school's District Office. Even if they share a plot of land and are owned by the same organization, the District Office serves a distinct and separate function from the K-12 School. Unless the Office building contains classrooms used by the school, these buildings would need to benchmark and certify separately.
For properties eligible to certify as a campus, a good guideline for determining whether a set of buildings is truly a campus is to ask whether the property’s operations would be substantially affected if one of the buildings were to be relocated. In the second example above, neither the K-12 School nor the District Office would be affected if the office were to move to another location 5 miles away, so they do not constitute a true campus (unless, as noted above, the District Office building contained classrooms used by the school). For a hotel consisting of multiple buildings, however, it would substantially affect the operations if a building containing guest rooms were to move 5 miles away from the building containing the restaurant, concierge, etc., so those buildings would be considered part of a cohesive campus.
