This ASHRAE manual provides those involved in the design, installation, and commissioning of HVAC systems for hospitals with a comprehensive reference source for their work. The text covers environmental comfort, infection control, energy conservation, life safety, and operation and maintenance, providing design strategies known to meet applicable standards and guidelines. It also contains information on disaster planning and provides "best practice" recommendations on temperature, humidity, air exchange, and pressure requirements for various types of rooms found in hospitals. A chapter on terminology begins to define several medical terms for the design engineer. ASHRAE Special Project 91.
