Indoor Air Quality and HVAC Systems is a practical guide for understanding the relationship between the design, installation, operation, and maintenance of HVAC systems and achieving indoor air quality (IAQ). The book describes the individual components of HVAC systems and the role each plays in maintaining good indoor air quality. It also identifies the techniques available for evaluating the performance characteristics of ventilation systems (including the use of carbon dioxide monitors and sulfur hexafluoride tracer testing equipment). Other topics discussed include the determination of pathways of air movement through buildings and understanding pressure relationships, ventilation effectiveness, and efficiency. The book concludes with an overview of sources of air contaminants to be concerned about when performing an IAQ evaluation. Indoor Air Quality and HVAC Systems provides critical information for industrial hygienists, HVAC contractors and engineers, and building owners and managers.

Health care HVAC systems serve facilities in which the population is uniquely vulnerable and exposed 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 24/7, and are owner occupied for long life. The HVAC systems in health care facilities must be carefully designed to be installed, operated and maintained in coordination with specialized buildings services, including emergency and normal power, plumbing and medical gas systems, automatic transport, fire protections and a myriad of IT systems, all within a limited building envelope.
