How? We use CO2 readings. People exhale a lot of CO2. How high CO2 concentrations go in a room is affected by the ventilation rate, occupancy of the room, activity of the individuals, and age. https://t.co/McbXYFZv3l For this classroom which had 17 3rd graders and 1 teacher, to meet code of 7.5 CFM/person, we expect the steady-state CO2 concentration (i.e. horizontally flat section) to be just below 1500ppm (see red line) The blue line is the CO2 curve associated with the more modern ASHRAE 62.1-2022 ventilation standard for classrooms of ~13-15 CFM/person, which is code in most places.

Show Kindness and Thanks: Printable Notes from Kids

  There's a lot going on in our state and world (with more to come). Our teachers and leaders need kindness and thankfulness during this time. Even if we don't agree on everything with some leaders, they still play a role in protecting our kids. And obviously our teachers and school administration and staff need support and love right now (and always). Their job is so hard and they are so amazing. So, let's show everyone the power of kindness. Let's spread LOVE. We think it would mean a lot to everyone. Handwritten notes from kids. Simply follow this link , print it out and hand over to your kids! Fill one out for yourself, too. Or, write a note on the back.
