I left my #Aranet4 monitor on the table in a hotel conference room during a meeting today. A fairly large room, around 30 people, but at least twice that would have fit comfortably. The room was overly air conditioned in the morning, and I suspect someone asked the staff to adjust the thermostat for the afternoon session ... which apparently further reduced the ventilation.
I was the only attendee masked.

#CO2 trace going to #GundamFactory #RX78F00:
* 0900-1200 riding the #JR to #Yokohama: levels peaking into 1800 ppm -- wear KN95+ mask
* 1300-1400 lunch indoors: peaks ~800 ppm
* 1400-1500 Dock tour! : < 600 ppm (outside levels)
* 1500-1600 Gundam Lab indoors: ~700 ppm
* JR back: > ~1000 ppm -- wear KN95+ mask -
"Bars in Belgium could be among the healthiest places to have a drink, come July. That’s when a new law goes into effect, requiring public venues to meet air-quality targets and display real-time measurements of carbon dioxide concentrations — a proxy for how much clean air is piped in."

#Aranet4 data logger capabilities allows one to simply calculate air changes per hour (ACH) by taking CO₂ decay data and plugging it in to a typical decay rate function.
The local facility manager continues to say these meeting houses are safe, to code and highly energy efficient! I agree only with the latter, 'energy efficient!" 😉

CW: covid, airplane ventilation
I think we made it through without #covid despite the over-3000 #covidCO2 #flight last week! #WearTheDamnMask (It's been 7 days, and all three of us are still feeling fine and negative on serial antigen tests.)
I wonder how everyone else is doing, though, considering that there was a lot of coughing and we were some of the very few people wearing snug KN95 #masks. 🥺

CW: covid, airplane ventilation
Airplane ventilation is still an issue. We took a half-full #United flight from Denver late on Dec. 28th, and CO2 (and temperature) spiked during boarding and especially de-icing. We were in KN95s but most (including crew) were not; lots of coughing. Levels dropped to around 1000 during the flight. #covidCO2 #CovidIsNotOver

On Wednesday I felt safe eating inside the Just Salad because I got low CO2 readings. Still, I thought I'd miscalibrated my PTH-8, since it gave low readings at Just Salad and Stumptown Coffee, and in the Admin Hub.
Then I took the 7 train home. There were delays due to a broken rail, so the train was very crowded, and the CO2 levels went up over 2000! Fortunately, they went down a bit once we got out of the tunnel and people started getting off the train... #covidCO2

"On a visit to a college town, we documented the highest level we saw: 3,500+ ppm CO₂. That was in a piano bar, an older building where the ventilation was poor; windows and doors were not cracked open. The number soared as more people entered the bar."

@JohanEmpa I tried it, and it reached the limit of this detector (3000 ppm), indicating as "HI". After removing from the bag, it took a while (3-5 minutes) to get back to the initial level of ~600ppm. #CovidCO2
