Classroom Air Quality and Temperature (11-06-19)

Research conducted at the University of California, Davis, indicates that the temperature and air quality in K-12 classrooms may be degrading students’ ability to learn.  A press release from Davis, reporting on a study from UC Davis and Lawrence Berkeley National Laboratory (Berkeley Lab) published in Building and Environment,states that “Roughly 85 percent of recently installed HVAC systems in K-12 classrooms investigated in California did not provide adequate ventilation. . . . researchers visited 104 classrooms . . . that had been retrofitted with new heating, ventilation and air conditioning, or HVAC, units in the past three years. . . . ‘Previous research has shown that under-ventilation of classrooms is common and negatively impacts student health and learning,’ [quote attributed to Rengie Chan from Berkeley Lab]. . . .ASHRAE, a global professional society that sets standards for building performance, specifies a minimum ventilation rate for classrooms of 15 cubic feet per minute per person. . . .researchers found only about 15 percent of classrooms met the ventilation standard.. . . thermal comfort impacts student performance. . . . about 60 percent of the classrooms were warmer than the recommended average maximum temperature range of 73 F.”
