Summary

The conventional approach to indoor air quality (IAQ) control uses outdoor air to dilute and remove indoor contaminants and mechanical filters to capture particles. Standards and codes specify outdoor air flow rates and minimum particle filtration requirements.  
 
The energy use associated with reliance on outdoor air has long been considered a barrier to improving IAQ. The concept of Equivalent Clean Air (ECA), which condenses the effects of all IAQ controls into a single measure, has the potential to overcome energy-focused objections to setting higher IAQ standards – IF air cleaners can be used effectively and safely in place of increased outdoor air.  

This webinar will describe: 

• How ECA is defined; 
• Review existing air cleaning technologies used to produce ECA; 
• How ECA is used in ASHRAE 241, Control of Infectious Aerosols; 
• How ECA can be generalized for use in minimum acceptable air quality standards such as ASHRAE Standard 62.1.
