HVAC systems in health care facilities provide a broad range of
services in support of populations who are uniquely vulnerable to an
elevated risk of health, fire, and safety hazard. These heavily regulated,
high-stakes facilities undergo continuous maintenance, verification,
inspection, and recertification; typically operate 24 hours/day, 7 days/
week; and are owner-occupied for long life cycles. Health care HVAC
systems must be installed, operated, and maintained in spatial and
functional conjunction with a host of other essential building services,
including emergency and normal power, plumbing and medical-gas
systems, automatic transport, fire protection, and myriad IT systems,
all within a constrained building envelope. Health care facilities and
services are characterized by high rates of modification because of the
continuously evolving science and economics of health care, and
consume large quantities of energy and potable water. The often unique
environmental conditions associated with these facilities, and the
critical performance, reliability, and maintainability of the HVAC
systems necessary to their success, demand a specialized set of
engineering practices and design criteria established by model codes
and standards and enforced by authorities having jurisdiction.
