2/ "THE WORLD IS CHANGING around us, and buildings are at the center of that change. So much so that the decisions we make today regarding our buildings will determine our collective health for generations to come. Winston Churchill’s famous quote has never been more apt.
3/ You may know that quote; many in the building world do. But you may not know that Churchill wasn’t making some grand statement about the societal impacts of our urban fabric when he uttered this now famous phrase.
4/ What Churchill had in mind was something very specific and relevant to him: how the parliamentary chamber had shaped Britain’s government, and therefore its people (the “us” in “our buildings shape us”).
5/ In 1943, the Commons Chamber was destroyed after a German Luftwaffe sortie dropped incendiary bombs on it during the Blitz. If you’re not familiar with the British Commons Chamber pre-1943 (why would you be?), it was a fiercely intimate setting.
6/ The intimacy was in fact its key feature. In this room, there was nowhere to run or hide. You made your argument face-to-face with your colleagues. Friend and foe alike could see fear or conviction in your eye. They could smell your breath.
7/ The convenings were, by design, a raucous affair (and often filled with colorful vitriol).
8/ The fire from the Luftwaffe’s incendiary bombs tore through the chamber, turning it to rubble. There was immediate discussion of replacing it with a bigger, more expansive chamber hall. (One with enough seats for all, for starters!)
9/ The idea of a vast chamber with semicircular seating was floated. That’s when Churchill made his famous declaration, “We shape our buildings and afterwards our buildings shape us.”
10/ Churchill recognized that the building had shaped their debate, their society, them. The intimate quarters of the Commons had shaped Britain. He was vehemently opposed to the semicircle idea.
11/ Now compare this with the US House Chamber.
Expansive, regal even, and lacking in intimacy: the semicircle that Churchill disdained. The room is not a boxing ring like the British Parliament.
12/ The US chambers inspire civil, comfortable, but wholly detached debates. The people in the back are a hundred feet from the person speaking. They definitely can’t see the speaker’s conviction, fear, or passion. The building shapes the debate."
13/ Thanks for reading! There's more to the Churchill story (and this short story is part of a chapter titled, "The Global Mega-changes Shaping Our World, Our Buildings, and Us) #HealthyBuildings amazon.com/Healthy-Buildi…

2/ Note that is *NOT* the ASHRAE group announced in December that they would release new ventilation targets in 6 months. So…the groups are not talking? Was this inadvertently dropped? Not sure this group knows what a big deal this is by slipping in 3-6ACH. Or maybe they do?
3/ Interesting (to me):
-they went w ACH over other metrics like cfm/p
-the targets roughly align with what we’ve put out for the last 3 years, except they use a lower lower-bound of 3ACH instead of 4-6
1/ “A global outbreak was thus seeded from a single person on a single day on a single floor of a Hong Kong hotel.”
The 2003 SARS epidemic exploded when an infected healthcare worker, suffering from minor respiratory symptoms, went to Hong Kong for a friend’s wedding...
2/ ...and checked into a ninth-floor room in the Metropole Hotel. He fell severely ill the next day, went to a hospital and died shortly thereafter — but not before transmitting Sars to 16 other guests with rooms on the same floor.
3/ These inadvertent hosts carried SARS to Canada, Vietnam, Singapore and across China.
Investigators from the World Health Organization summed it up best: “A global outbreak was thus seeded from a single person on a single day on a single floor of a Hong Kong hotel.”
For anyone who thought of, and pushed, the JUUL and smoking cessation narrative, rather than as vehicle for addicting more (young) users...quite a partnership brewing...
Absolutely critical and not discussed enough. The failure of ASHRAE - *the* standard setting body for ventilation - to set a ventilation target during the pandemic for a respiratory virus that spreads entirely indoors in under ventilated spaces.
For those who do not know, ASHRAE did have a group working on this. Excellent scientists. They produced a ventilation target last year. Never saw the light of day. Why?
Some in my own field like to throw daggers every which way - WHO, CDC, frontline public health officials - but have not looked inward at the failings of our own field. Many have close ties to ASHRAE and that might be the reason. This is holding us back.
First class today and I brought up new #chatGPT policy. Sharing in case others find helpful.
Background: for one assignment students create a two-page summary for the public on a #HealthyBuildings topic.
🧵
2/ Answer basic questions: what is it? Why it matters for health? What are solutions. Topics can be anything (asbestos, VOCs, nano materials, green cleaners, SARS-CoV-2…)
3/ aside: Why only 2 pages? b/c it’s *hard* to write concisely for the public. It’s easy to spew out 5 pages.
--> SARS- CoV-2 and other respiratory pathogens transmit through inhalation exposure indoors, mostly in places with inadequate ventilation and filtration
--> Current building standards promote bare-minimum ventilation and filtration targets
That's why our @Lancet@Commissioncovid Task Force on Safe Work/School/Travel wrote this report, which proposes better ventilation and filtration targets
