"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!" 😉

"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."
