Enhancing Health by Filtration of PM2.5 & Infectious Aerosols
The health impacts of PM2.5 including particles from wildfire smoke, indoor combustion, and other sources of PM2.5 will be reviewed including a recent report from the National Academies of Science, recently revised standards and practical approaches to reduce exposure.
The harm from PM2.5 as well as key chemical contaminants will be reviewed with a path to reducing ventilation and improving IAQ while saving energy using the IAQP procedure will be described.
Filtration requirements of various ASHRAE standards including ASHRAE 62.1 Ventilation for Acceptable Indoor Air Quality, ASHRAE 62.2 Ventilation for Acceptable Indoor Air Quality in Residential Buildings, and ASHRAE 241 Control of Infectious Aerosols will be compared. Additional ASHRAE standards including ASHRAE 90.2 High-Performance Energy Design of Residential Buildings, and others will be reviewed for filtration requirements.
A special emphasis will be placed on ASHRAE 241 Control of Infectious Aerosols and how equivalent clean airflow per person for infection risk mitigation can be calculated or measured directly (using Normative Appendix C). Data showing the opportunity for energy savings and decarbonization in commercial buildings while providing enhanced control of infectious aerosols will be presented.
