  1. Off to work I go! I am so grateful to my clients that understand that I crash sometimes. #POTs sucks. However, my supportive community rocks! I’m now taking appointments as early as 11am starting today! #CCBiz #CovidAware #HEPA #ASHRAE

  2. ‘First ever #ASHRAE standard on reducing the risk of indoor infectious #aerosol transmission sets new targets for building operators in terms of air system design, installation, operation, and maintenance.’

  3. The air filter recommendation tool at filters.cleanairstars.com now incorporates #ASHRAE 241 IRMM (Infection Risk Management Mode) targets.
    It’s important to understand the rated occupancy for your space and use this when entering the number of occupants, rather than how many occupants will actually be present in the space.

    See an example here for 15 occupants in a small US retail store context under 45dBA noise level.

    Hoping to see info here this month on the final draft of the #ASHRAE #IAQ pathogen mitigation standard.

    ASHRAE Standard 241P, Control of Infectious Aerosols provides minimum requirements for HVAC-related measures to reduce the risk of transmission of COVID-19, influenza, and other airborne viruses in offices, schools, hospitals during periods of high risk. The standard offers guidance for creating healthier environments in buildings where we work, live, and play.

    The scope is specifically about mitigating long range transmission. Nothing for short range transmission. Plexiglass is gone, thankfully.

    Right at the beginning, it gives you the equivalent outdoor air rates. Looks pretty good.

    They finally provide a table for MERV rating and pathogen removal efficiency.

    Existing building operation is addressed.
    Building Monitoring & Operations - This is where the biggest problem with ventilation occurs. It's designed one way and works for a couple of years. There is no oversight for HVAC mechanics/maintenance technicians. ASHRAE has guidelines for maintaining equipment, but this isn't legally enforced.

    In Appendix A, they create a standard for safe and effective use of electronic air cleaning equipment. For safety, they provide limits for all the main pollutants, instead of just ozone which is traditionally done.
    They require no statistically significant increase from formaldehyde and particulate matter (as well as others).

    Fair. I'll raise the ante and argue that INDOOR environmental protection be an #EPA purview. Pretty clear #cdc isn't going to champion the issue, and it's not just #osha of course.
    I'm cautiously curious about how the new #ASHRAE cmte pursues its work. And we mere mortals can't wait 6 months for their recs. I'll have #library #CO2Monitor loan program proposal submitted to East #TN libraries first week of January... Plz contact if interested!

  11. Where are the #IAQ engineer / scientist / PH and other eligible #HealthyAir warriors who will apply to participate on this #ASHRAE #airborne infection mitigation cmte ??
    Need not be ASHRAE member.
    December 23 application deadline!
