occupancy or temperature during occupied hours. In homes and buildings where the HVAC fan operation can be controlled at the thermostat, set the fan to the "on" position instead of "auto," which will operate the fan continuously, even when heating or air-conditioning is not required. • Open outdoor air dampers beyond minimum settings to reduce or eliminate HVAC air recirculation. In mild weather, this will not affect thermal comfort or humidity. However, this may be difficult to do in cold, hot, or humid weather. • Improve central air filtration: • Increase air filtration to as high as possible without significantly reducing design airflow. • Inspect filter housing and racks to ensure appropriate filter fit and check for ways to minimize filter bypass. • Check filters to ensure they are within their service life and appropriately installed. • Consider portable high -efficiency particulate air (HEPA) fan/filtration systems to help enhance air cleaning (especially in higher risk areas such as a nurse's office or areas frequently inhabited by persons with higher likelihood of COVID-19 and/or increased risk of getting COVID-19). • Generate clean -to -less -clean air movement by re-evaluating the positioning of supply and exhaust air diffusers and/or dampers (especially in higher risk areas). • Consider using ultraviolet germicidal irradiation (UVGI) as a supplement to help inactivate SARS-CoV-2, especially if options for increasing room ventilation are limited. • In non-residential settings, consider running the HVAC system at maximum outside airflow for 2 hours before and after the building is occupied. Trane has provided a proposal to implement changes to the New Brighton Community Center HVAC that fall in line with CDC recommendations. That proposal along with the air quality assessment is included in the packet. Director Fink, Assistant Director Hicks and a representative from Trane will be attending and able to answer any questions. The cost of this proposal is $209,433. We propose that this project be funded using dollars from the Community Reinvestment Fund. L Jennifer Fi k, CPRP Director of Parks and Recreation
