• Air Cleaning: Air cleaners such as germicidal ultraviolet air disinfection may also be considered to supplement ventilation and filtration. Technologies and specific equipment should be evaluated to ensure they will effectively clean indoor air without generating additional contaminants or negatively impacting space air distribution by creating strong air currents. • Temperature and Humidity: It is desirable to set the thermostat at the higher end of the comfort zone, 7578ºF and maintain relative humidity between 40-60%. • Energy Use Considerations: In selecting mitigation strategies, consideration should be given to energy use as there may be multiple ways to achieve performance goals that have greatly different energy use impact. Control changes and use of energy recovery to limit or offset the effect of changes in outdoor air ventilation rate and filter efficiency may reduce or offset energy and operating cost penalties.
• Water System Precautions: Buildings that have been unoccupied could have stagnant water, and water systems should be flushed to remove potential contaminants. Utilizing ASHRAE Standard 188 and Guideline 12 can help minimize the risk of water-borne pathogens such as legionella.

About ASHRAE Founded in 1894, ASHRAE is a global professional society committed to serve humanity by advancing the arts and sciences of heating ventilation, air conditioning, refrigeration and their allied fields. As an industry leader in research, standards writing, publishing, certification and continuing education, ASHRAE and its members are dedicated to promoting a healthy and sustainable built environment for all, through strategic partnerships with organizations in the HVAC&R community and across related industries. ASHRAE is celebrating 125 years of shaping the built environment.
“The task force’s approach to protecting indoor air quality in polling place is practical, and can help safeguard voters, poll workers and other building occupants as most sites are shared locations that serve many different purposes,” said Luke Leung, ASHRAE Epidemic Task Force commercial/retail team lead. ASHRAE’s Epidemic Task Force has developed guidance and building readiness information for different operating conditions and several building types, including commercial, residential, educational, and healthcare facilities.
