A majority of schools, 56 percent, reported that various environmental factors, taken together, did not interfere at all with the delivery of instruction in permanent buildings, while the remainder reported at least some interference: 33 percent reported minor interference, 9 percent reported moderate interference, and only 1 percent reported major interference.
In permanent buildings, heating and air-conditioning were the most frequently reported interferences, with less than half of schools reporting that air-conditioning did not interfere at all with instruction. Air-conditioning interfered to a moderate or major extent in permanent buildings in 16 percent of schools; heating interfered to a moderate or major extent in 13 percent of schools. Schools reported less severe interference from heating and air-conditioning in portable buildings, with 11 percent of schools reporting moderate to major interference from air-conditioning, and 9 percent reporting the same from heating.
In portable buildings, acoustics or noise control was reported to be a moderate or major problem in 18 percent of schools, compared to 12 percent for permanent buildings.
The size or configuration of rooms was reported as moderate or major interference in portable buildings by 16 percent of schools. The interference was less severe in permanent buildings, with 13 percent of schools reporting moderate or major interference.
Portable buildings also had more severe interference from ventilation and indoor air quality than permanent buildings. Ventilation in portable buildings was a moderate to major problem in 14 percent of schools; 11 percent of schools had moderate to major interference from ventilation in permanent buildings. Indoor air quality interfered with instruction to a moderate or major extent in portable classrooms in 12 percent of schools; permanent buildings had moderate to major interference from indoor air quality in 10 percent of schools.
