Nosocomial diseases are diseases that originate within hospital or healthcare facilities. Those types of diseases pose significant risks to patients staying within hospital or healthcare facilities as patients are often elderly or already have compromised immune systems. Often, the diseases are airborne or waterborne and frequently spread through the building’s utility systems, such as the heating, ventilation, and air conditioning, (HVAC), or water system. This report describes a proof of concept to identify parts of an HVAC system that may be affected by a contaminate, and which rooms within the building are at risk of spreading the contaminate. The implementation involved converting CAD data to file geodatabase feature classes which are in turn used to build a geometric network. Tracing analysis is then used to identify rooms and HVAC vents likely affected by a contaminate based on an input room. The tool developed for this project can both identify which rooms may be affected by a pollutant but also generate a list of rooms to sample when developing a preventative testing schedule.
