Dan Koenigshofer, P.E., MSPH, HFDP, SASHE, and John Roberts, P.E., MSPH, HFDP, LEED AP BD+C, have been recognized with the 2018 Journal Paper of the Year by the ASHRAE Journal. The American Society of Heating, Refrigerating and Air-Conditioning Engineers seeks to advance the arts and sciences of heating, ventilating, air conditioning and refrigerating to serve humanity and promote a sustainable world. The organization has more than 50,000 members worldwide.
In their article entitled “Do OA Economizers Make ‘Cents’ in Hospitals?,” Koenigshofer and Roberts detail the costs and savings of utilizing outside air economizers in hospital ventilation systems. They concluded that these systems do not make “cents” in hospitals. The findings have major implications for building codes throughout the U.S. North Carolina has changed its code to no longer require these systems.
