"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!" 😉

#CO2 reading of 534 ppm* in my #Brooklyn apartment this AM—one adult (me) and two cats. One window cracked open -2 inches. Not bad!

Note: reading was taken after I’d been rushing around doing household chores (i.e. vacuuming, washing dishes) for 30 minutes, so I suspect I would’ve gotten a lower reading if I’d been sentient.

*Accuracy of CO2 monitor estimated +/- 50 ppm

#CO2 reading of 1018 ppm* on #NYC #MTA bus in #Brooklyn this AM—6 other riders (all unmasked), me (#N95), plus the bus driver (unmasked). One window open.

The past week, #NYC #MTA buses have been consistently packed with maskless people, including many small children with wet coughs. Truly an unfortunate time to have no other options besides public transit 😖
