The invention is an airborne infection control monitoring, condition data collection, testing and reporting system. The system includes new sensors and other equipment needed to collect HVAC data, the placement of the sensors in the HVAC system, software needed to retrieve the data, and the algorithms used in analyzing the data to the required building design specifications. The proposed method and system would collect current room condition data and apply it to a virtual ventilation, room and equipment structure to efficiently determine if the building's rooms meet the air balance and infection control requirements.
