Abstract

This Guide applies to small healthcare facilities up to 90,000 ft2 in areas including acute care, outpatient surgical, small critical access, and inpatient community hospitals. These facilities typically include all or some of the following types of space usage: patient rooms, surgery, emergency department, radiology, administration, dining and food preparation, post anesthesia care unit (PACU), and recovery. The primary focus of this Guide is new construction, but recommendations may be similarly applicable in their entirety to facilities undergoing total renovation and in part to many other healthcare renovation, addition, remodeling, and modernization projects (including changes to one or more systems in existing buildings). The small healthcare facilities included in the scope of this Guide are facilities smaller than 90,000 ft2 defined as • small acute care hospitals, • small inpatient community hospitals, • critical access hospitals with 25 beds or fewer, • outpatient surgical facilities, • freestanding birthing centers (similar to outpatient surgical centers), • gastrointestinal endoscopy facilities (similar to outpatient surgical centers), • renal dialysis centers (similar to medical office buildings), • primary care outpatient centers, • small primary (neighborhood) outpatient facilities, • freestanding outpatient diagnostic and treatment facilities, • freestanding urgent care facilities, or • medical office buildings (greater than 20,000 ft2). Included in the Guide are recommendations for the design of the building envelope; fenestration; lighting systems (including electrical lights and daylighting); heating, ventilation, and air-conditioning (HVAC) systems; building automation and controls; outside air (OA) treatment; and service water heating (SWH). Additional savings recommendations are also included but are not necessary for 30% savings. These additional savings recommendations are discussed in the Bonus Savings section of Chapter 5 and provide recommendations for process/plug/phantom loads, renewable energy systems, alternative hot water systems, alternative HVAC systems, and electrical distribution. The recommendation tables do not include all the components listed in ASHRAE/ IESNA Standard 90.1-1999. Though this Guide focuses only on the primary energy systems within a building, the underlying energy analysis presumes that all the other components are built to the criteria in Standard 90.1 and ASHRAE Standard 170, Ventilation of Health Care Facilities. Certain aspects of energy-efficient design, including steam heat, vehicles and other maintenance areas, and sewage disposal, are excluded from this Guide. Significant energy efficiency opportunities may be available in these areas, and Guide users are encouraged to take advantage of these opportunities and treat them as "bonuses" beyond the 30% target. In addition, the Guide is not intended to substitute for rating systems or references that address the full range of sustainable issues in healthcare design, such as acoustics, productivity, indoor air quality (IAQ), water efficiency, landscaping, and transportation, except as they relate to energy use. Nor is it a design text. The Guide assumes good design skills and expertise in healthcare and hospital design.
