District-collected carbon dioxide data
Carbon dioxide builds up over the day in classrooms that are poorly ventilated. Portland Public Schools sometimes monitors or obtains carbon dioxide measurements using equipment that the district owns, or via contractors placing carbon dioxide monitors in classrooms. All schools had a smattering of carbon dioxide measurements taken before a return to in-person learning in the IAQ reports, but this data is not very useful because it was a one-time measurement when kids were not in class. Here is information about a subset of schools carbon dioxide data collected by PPS since March 2021 – other than the one-off measurement from the IAQ reports:
Boise-Eliot – no data collected between March 1, 2021 and Feb 10, 2023
