ASHRAE approves groundbreaking Standard to safeguard indoor spaces from disease transmission. The new ASHRAE Standard 241- Control of Infectious Aerosols is a major step forward in reducing the risk of infectious disease spread in buildings. bit.ly/3pkMDAg.

We’ve known how to prevent dust and sand storms for nearly a century, but these storms will likely grow in intensity as farming expands and climate change intensifies

Our study on sources and concentrations of diverse air pollutants in homes and optimal sensor positioning. See the open-access publication to learn more: doi.org/10.1016/j.envres.202…
Kudos to Viviana González and Yale colleagues Krystal Pollitt and Elizabeth Lin for pulling this off.

Older adults emit at least twice as many aerosol respiratory particles per minute than young adults, whether at rest or while exercising, according to a study with implications for viral transmission dynamics. In PNAS: ow.ly/iAAi50OuqgR

The ASHRAE project committee that is developing Standard 241P Control of Infectious Aerosols approved a public review draft today. It will be posted soon for a two-week public review.

This week we welcomed Jie Zhao, PhD VP at Delos Labs for a show on how modern buildings are integrating IEQ controls, lighting, acoustics and more to make work environments healthy and high performing.

How do we design buildings to reduce infectious aerosol transmission risk? In collaboration with @SafeTraces @ProfKAHamilton @StanDeresinski and Peter Cook we demonstrate a method of scaling a QMRA model with aerosolized synthetic DNA measurements, pubs.acs.org/doi/10.1021/acs…
Cool story! Extra cool because I got to tag along 😉

Very nice new study “proving” viable sars2 virus in bioaerosols
Of course, this was obvious as soon as the 1st superspreader events happened
Many scientists were yelling it
Took far too long to be accepted by public health agencies & impact policy

Meet Shelby Buckley, an environmental engineering student in @CUEngineering that recently studied the impacts of climate change up close during a five-week trip to the Arctic aboard an icebreaking ship.

I ❤️ low-cost sensors for PM air pollution (eg PMS5003, SPS30). But they have serious limitations. They cannot see particles > 1 micron.
PM1 👍🏻 😀
PM2.5 🧐
PM2.5-10 👎🏻😬
PM10 👎🏻 ☹️
Networks like #PurpleAir should stop reporting PM10 and coarse PM. doi.org/10.1021/acs.estlett.…

Indoor air pollution made visible! Five days of filtering particulate matter = noticeably dirty filter. Better on the filter than in our lungs! Now that its ASHRAE volunteer service is done, this #CorsiRosenthalBox is off to a new home. Many more particles to catch!

#CorsiRosenthalBox in the wild at the @ashraenews conference. Getting enhanced IAQ in the committee meeting of the Guideline for Enhanced IAQ! ASHRAE friends, join us in International Ballroom B to keep the construction going. 7 am onward each day. DM me!

📢 New paper alert ! 📢
Q: How might we eliminate race/ethnic disparity in PM2.5 exposures nationwide?
Major result: Clean Air Act's most powerful tools can't resolve these disparities. But there is a different approach that could have huge EJ benefit.
