Comfort in classrooms engenders learning and countless factors contribute to the quality of an educational environment. A longitudinal study measuring classroom conditions, including indoor air quality, lighting, and acoustic components has amassed data from 220 schools in the Eastern Nebraska area. Measurements logged at time intervals no longer than 5 minutes were taken for two full days in each classroom, three times in a year. Using this data, the relationships over time that acoustic factors have with indoor air quality, thermal comfort, and lighting factors are explored. Correlations are investigated between average measured values, time and spatial variation of measured values, and spectral composition of the acoustic metrics. Besides correlations between the assorted measured quantities, other relationships between the design of the building mechanical and lighting systems and resulting acoustic conditions are discussed; for example, do heat pumps or VAV boxes contribute to significantly different acoustic conditions?
