Ventilation standards are set by NIOSH and ASHRAE, IL State Board of education uses those standards to determine if ventilation is appropriate. Its often based upon number of air changes per hour for the occupancy of the rooms/buildings, and the minimum and maximum temperature that can be maintained at that occupancy.
I don't know the details of the ventilation assessments of each building ,but I recall the school board held a public meeting in one of those un-airconditioned schools this summer, so people can get a sense of what its like to be in an unconditioned space with a bunch of other people.
So a guy misspoke and the entire school district will be held untrustworthy in perpetuity. Its not uncommon for public officials to misstate their understanding of the codes. happens more frequently than it should.
I get that D150 has lots of problems and made lots of mistakes and has completely lost the public trust.
But is it realistic to think that the district can maintain its entire infrastructure of 24 schools and associated buildings, parking, roofs, ventilation, at current funding levels in perpetuity?
