Title: Air Conditioning for the Environment of Care
The time has come for the public to begin reoccupying buildings all across the country, yet there still remains great concern about the possibility of transmission through the air of various pathogens (especially SARS-CoV-2) among individuals in both private and public sectors.
The ASHRAE Position Document on Infectious Aerosols outlines HVAC-system recommendations for various buildings and facilities which are aimed at reducing occupant exposure to airborne disease. Practices addressed include ventilation-related strategies comprised of dilution, airflow patterns, pressurization, temperature/humidity distribution-and-control, filtration, and other “best practice” approaches.
This presentation will provide a basic understanding of these recommendations. It will also include an expanded discussion that covers suggested HVAC system upgrades that (when combined with more traditional approaches) may result in superior environmental quality, health, safety, and comfort for occupants within building structures of all types.
Topics addressed will include:
- The latest ASHRAE guidelines and recommendations.
- Mechanical filtration upgrades.
- Proper humidity design & control.
- UVGI systems for coil, in-duct, and upper room use.
- Bipolar Air ionization & other advanced IAQ technologies.
- Ozone considerations, concerns, and regulations.
- Specific COVID-19 recommendations.
