So, perhaps death and disability due to Covid are just treatable symptoms of a bad attitude...

According to the latest CDC wastewater data, 35 states have very high or high levels of COVID-19.

According to the latest CDC COVID-19 wastewater data, we are currently in the second-biggest surge of the pandemic.

It will peak in the next week, with ~2 million infections per day. During this surge, ~100 million people total (~1 in 3 people in the US) will likely get COVID.

This was called a foul against Penn State and it cost PSU the game. What a joke.

...and we don't assume that because the earthquake happened last week we don't need to worry that there might be another one sometime.

I asked an engineer, “are many of your colleagues still concerned about designing structures strong enough that they don’t collapse?”

Answer: “Yes. Licensed engineers are legally required to protect the public welfare.”

It’s not that difficult.

Beware the potential for systematic reviews to rigorously reach the wrong conclusion.

This is an exciting step towards improving indoor air quality, taken by Rep Bill Driscoll Jr for Massachusetts! You can choose what to eat and drink... you can choose your friends... but you can't choose what air to breathe! Everyone deserves healthy air.

In-operation regulation is needed.

'Powers said the legislation lays out the framework under which rules and regulations will be created to gather information about indoor air quality and make it public. He and Levine hope the standards might be a model for other cities.'

'Stop' is an optimistic expectation, but ASHRAE 241 will help. I look forward to a stimulating conversation tomorrow. Thanks to everyone for their interest, not in this chat, but in making IAQ better and limiting the damage done by airborne diseases.

I'll be participating in a GSA/NASEM webinar on July 27 that may be of interest to some. 'Enhanced Ventilation and Cleaner Air in Buildings.' Also speaking - Brian Gilligan (GSA), Vivian Loftness (Carnegie Mellon), Kevin Keene (PNNL).
