|Title:||Multizone Modeling of Strategies to Reduce the Spread of Airborne Infectious Agents in Healthcare Facilities|
|Published:||February 01, 2013|
|Abstract:||Control of airborne infectious agents in hospitals is critical both to effective health care and to the control of direct and indirect health care costs. Current hospital design guidelines focus on ventilation rates, room pressure control and air filtration to control the spread of airborne infectious agents. Studies indicate, however, that there is much variability in hospital design strategies used by engineers to control airborne pathogens. This study focuses on a number of questions concerning current hospital design practices and provides an overview of the tools and methods that can be used to answer some of these questions. Multizone airflow and contaminant transport simulations are used to examine different control strategies and some related issues of design and application. Design issues associated with room pressurization, filtration, and ultraviolet germicidal irradiation (UVGI) are also reviewed.|
