PORTFOLIO MANAGER - SPACE CLASSIFICATION GUIDE 1 HEALTHCARE ENERGYSTAR 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. Other Healthcare Building Other Healthcare Building 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. Medical Office Building Parking Lot 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. »EPA www.energystar.gov/benchmark United States Environmental Protection Agency September 2005 xxx xxxxxx E-mail: buildings@energystar.gov ------- |
