HOW TO CLASSIFY HEALTHCARE SPACE
IN PORTFOLIO MANAGER
The EPA energy performance rating system—Portfolio Manager—is
designed to benchmark the energy performance of:
1)	acute care and children's hospital campuses,
2)	free-standing acute care and children's hospitals, and
3)	free-standing medical office buildings.
The acute care hospital, children's hospital, or medical office space
must be at least 50 percent of the total healthcare property to use
the rating system. These space types are designated as "primary
space" and cannot be defined in the same benchmark with another
primary space type. The following illustrations provide guidance on
how to define your healthcare property for accurate benchmarking.
ACUTE CARE AND CHILDREN'S HOSPITAL
The graphics below depict the two ways in which a healthcare campus or hospital can be benchmarked using EPA's rating system.
• An acute care or children's hospital campus (multiple-
buildings): The sum of all square footage and energy usage of all
buildings and supporting functions (such as administrative offices,
skilled nursing, long-term care, medical offices, exam rooms, lobbies,
cafeterias) is included in the aggregate, gross square footage for the
campus. The campus includes all related buildings that are connect-
ed by corridors or walkways or are in close proximity to one another.
If medical office space is located on the campus, it should be includ-
ed in the aggregate, gross square footage for the campus. Computer
data centers, parking garages or lots are secondary spaces that can
be benchmarked with an acute care or children's hospital.

Acute Care or Children's Hospital Campus
• A free-standing acute care or children's hospital: The sum of
all square footage and energy usage for the hospital and support-
ing functions is included in the aggregate, gross square footage for
the hospital.
Free-Standing Acute Care or Children's Hospital
Acute care and children's hospitals are facilities that
typically provide a variety of services within the same
building or among multiple buildings on a campus, includ-
ing emergency medical care, physician's office services,
diagnostic care, ambulatory care, and surgical care.

| MEDICAL OFFICE BUILDING
If separately metered, a medical office building can also be bench-
marked as a free-standing facility. The floor area for all supporting
functions, such as ambulatory surgical centers, food facilities, lob-
bies, elevator shafts, stairways, are included in the total gross
square footage.
Medical office space can also be defined as a secondary space with-
in a traditional office building. See the Quick Reference Guide for
Office Space for additional details on benchmarking an office build-
ing with less than 50% medical office square footage.

SECONDARY SPACE
Medical office space is primarily used to provide
diagnosis and treatment for medical, dental, or psychiatric
outpatient care.
Currently, the rating system is unable
to benchmark:
•	Healthcare campuses where the hospital
square footage is less than 50 percent of the
total conditioned space of the campus
•	Hospitals that are not acute care or children's
•	Medical office as a free-standing facility if the
energy is not separately metered
Secondary space such as computer data centers, ambulatory surgical
center, parking lots or garages, has a different energy profile than
primary space and must be identified separately in the rating system.
The aggregate square footage of secondary space must be less than
50 percent of the total gross square footage of the hospital, hospital
campus, or medical office. Although the rating system provides
"other" as a secondary space, it is not intended for benchmarking
healthcare space.
