HOW TO CLASSIFY HOSPITAL AND MEDICAL
OFFICE SPACE IN EPA'S PORTFOLIO MANAGER
The U.S.. EPA's ENERGY STAR measurement and tracking tool, Portfolio
Manager, allows you to track and assess energy performance and
receive an ENERGY STAR energy performance score for:
1.	Hospital campuses,
2.	Free-standing hospitals, and
3.	Free-standing medical office buildings.
The hospital or medical office must comprise more than 50 percent of
the total facility square footage to receive an ENERGY STAR score. The
following illustrations provide guidance on how to define a healthcare
facility for accurate benchmarking within Portfolio Manager.
HOSPITAL
The term "Hospital" accounts for all clinical and non-clinical spaces
located within a campus or building, including medical and administra-
tive offices, dormitory, hotel, retail spaces, and skilled nursing. The
graphics below depict the two ways to properly categorize space to
benchmark a hospital campus or free-standing hospital.
Hospital campus (multiple buildings):
In Portfolio Manager, during the "Add a Property" step, all hospitals
and hospital campuses should select "A hospital composed of a single
facility or collection of facilities" for the Property Type.
A hospital campus includes all related buildings that are connected by
corridors or walkways, or which are in close proximity to one another.
When defining the "Hospital (General Medical and Surgical)" in the
Space Use section of Portfolio Manager, the space attributes must be
the aggregate of all of the buildings on the campus. Specifically, when
calculating the floor area, aggregate the floor area of all buildings on
the campus, including supporting functions such as: stairways, connect-
ing corridors between buildings, medical offices, exam rooms, labo-
ratories, lobbies, atria, cafeterias, storage areas, elevator shafts, and
any space affiliated with emergency medical care or diagnostic care.
Additionally, if medical office space is located on the campus, it should
be included in the gross square footage of the campus.
Computer data centers and parking garages or lots are secondary
spaces that, if present, must be entered in Portfolio Manager as a
secondary space. See Secondary Spaces below for more information.

Hospital Definition
Hospital types that are eligible to be scored in
Portfolio Manager include general medical and surgi-
cal hospitals, critical access hospitals, and children's
hospitals. These facilities provide acute care service
intended to treat patients for short periods of time,
including emergency medical care, physicians' office
services, diagnostic care, ambulatory care, surgical
care, and limited specialty services such as rehabili-
tation and cancer care. Hospitals that use more than
50 percent of the gross floor area or have more than
50 percent of their beds set-up and staffed for use for
medical services such as long-term care, psychiatric
care, and/or specialty care are not eligible to receive
an ENERGY STAR score at this time. However, these
facilities can receive a weather normalized energy
use intensity by benchmarking under "Other" in
Portfolio Manager.

A free-standing hospital:
In Portfolio Manager, during the "Add a Property" step, all hospitals
and hospital campuses should select "A hospital composed of a single
facility or collection of facilities" for the Property Type.
When defining the "Hospital (General Medical and Surgical)" in the
Space Use section of Portfolio Manager, the sum of all square footage
and energy usage for the hospital and supporting functions should be
included in the aggregate, gross square footage and energy consumption
of the hospital.
Computer data centers and parking garages or lots are secondary
spaces that, if present, must be entered in Portfolio Manager as a
secondary space. See Secondary Spaces below for more information.
| MEDICAL OFFICE BUILDING	
Medical office building total gross square footage should include floor
area for all supporting functions, such as ambulatory surgical centers,
food facilities, lobbies, elevator shafts, and stairways.
Computer data centers and parking garages or lots, if present, must be
benchmarked as secondary spaces.
If a medical office building is part of a hospital campus and is sepa-
rately metered, it must be entered as part of the hospital campus
square footage, but it can also be entered separately in Portfolio
Manager as a free-standing medical office building to receive its own
ENERGY STAR score.

Medical offices with ambulatory surgical centers (ASCs) may not receive
a valid score due to the limitations of the dataset used to derive the
ENERGY STAR score. Portfolio Manager may score medical office build-
ings with ASCs lower than those without ASCs.
Medical office space within a traditional office building can also be
defined as a secondary space. See the Quick Reference Guide for
Office Space for details on benchmarking an office building with less
than 50 percent medical office square footage.

Medical Office Building Definition
Medical Office Building applies to buildings in which
more than 50 percent of total facility space is used pri-
marily to provide diagnosis and treatment for medical,
dental, or psychiatric outpatient care.
| SECONDARY SPACES	
Parking, data centers, and pools have different energy profiles than
hospitals or medical office buildings and must be identified separately
as secondary spaces. The aggregate square footage of secondary
space must be less than 50 percent of the total gross square footage of
the hospital or medical office building for the facility to receive a valid
ENERGY STAR score.
1. Parking Lots and/or Garages
Enter the characteristics under the "Parking" space type, including
gross square footage. The aggregate square footage of secondary
space parking structures (e.g., garages) must be less than 50 percent of
the total gross square footage of the hospital or medical office building
for the facility to receive a valid ENERGY STAR score. There are no
restrictions on the size of parking lots. If the parking or garage
space is sub-metered, do not enter the square footage or energy
use in Portfolio Manager.
2.	Data Centers
Enter the characteristics of this space under the "Data Center" space
type. A data center is for sophisticated computing. It should not be
used to represent a server closet or computer training area. If the floor
area of a data center is greater than 10 percent of the total floor area
of the facility, the facility is not eligible for an ENERGY STAR score.
3.	Swimming Pools
If the facility has a swimming pool, enter the characteristics of this
space under the "Swimming Pool" space type.
