PORTFOLIO MANAGER ¦ SPACE CLASSIFICATION GUIDE ———- HOSPITALS & MEDICAL OFFICE BUILDINGS ENERGYSTAR 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. Data Center 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.

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. Hospital Illustration of Free-Standing Hospital 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. Illustration of Free-Standing Medical Office Building Office Medical Building Parking Lot 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.
