When I was a student I had a little room and one time I had a co2 monitor in my room for a few days. The monitor had 3 leds, green yellow and red. While sitting in the room for three consecutive hours (at the computer) the co2 would slowly rise from green to red and after opening the window for a while it was back at green. Now the interesting part is that I felt a strong correlation between tiredness and high co2 levels (I was surprised how strong this effect was) and that opening the window really did help. Since then I thought that every classroom needs such a device.
- faceplanted 7y agoWould definitely be an interesting longitudinal study to put a sensor in a set of classrooms, some of them with a your light system to suggest opening a window, and some of them not being told about the sensor, which would just log data as a control. You could compare grades and long term success in people in those classes. Even in the short term it would be interesting to see if it affects any education metrics.
- antcas 7y agoWe should also pump in enough CO2 to equalize an open window room and control for CO2 level vs psychological affects of a breeze and an open window.
