Alexandra Dragan, Ph.D., P.E., receives an ASHRAE Symposium Paper Award for her paper, Comparative Analysis of HVAC Systems That Minimize the Risk of Airborne Infectious Disease Transmission.

Most tuberculosis (TB) contamination occurs from unknown and unsuspected TB carriers, according to published statistical data.It can be found in many areas of a health-care facility where, based on building code requirements, air is not exhausted to the outside but recirculated to other areas of the facility.Although any system exhausting instead of recirculating the air greatly minimizes the risk of contamination, all-exhaust systems are not used because of their increased energy consumption.As an alternative method, recirculated air is HEPA filtered.
The paper presents the results of a life-cycle cost analysis performed on a health-care facility using five alternatives, recirculation, HEPA filtration or 100% exhaust applied to the waiting rooms and HEPA filtration and 100% exhaust applied to the entire building for three locations.
