Popular options include:
• Ultraviolet germicidal irradiation (UVGI): UVGI uses
short-wavelength ultraviolet light to kill or inactivate microorganisms and can be installed near ceilings or within HVAC equipment.
• Bipolar ionization (BPI) and needlepoint bipolar ionization (NBPI): BPI and NBPI produce a stream of ions that attract viral particles to cling together, improving the effectiveness of filter systems. Studies regarding the application of BPI and NBPI to mitigate the risk of pathogens such as SARS-CoV-2 are ongoing.
Importance of Energy Efficiency
HVAC systems typically account for approximately 40% of the energy usage in commercial buildings. Upgrading an HVAC system to improve IAQ will likely increase energy consump- tion. To minimize HVAC operating costs when incorporating IAQ upgrades, make sure to comply with the latest guidelines for ASHRAE 90.1, which provides minimum energy efficiency requirements for building design and local energy codes.
Recommendations
tractor familiar with CDC ventilation guidelines, ASHRAE Standard 62.1 and ASHRAE 90.1. If new HVAC equipment is needed, make sure that the manufacturer performance claims are verified by an independent, third-party, certified ratings program. Trade associations such as the Air Movement and Control Association (AMCA) and Air Conditioning Heating Refrigeration Institute (AHRI) have excellent performance certification programs in place to ensure that manufacturers’ products perform as specified.
Using ESSER Funds to maximize HVAC system operation, mitigate the risk of COVID-19 and improve IAQ will ensure students can safely attend school in a healthy environment that maximizes their ability to learn.
