It doesn’t get much more sensitive in HVAC design than designing ventilation systems for the schools that our youth occupy during their learning years. These students are the future of America. These are the youth whom we want and need to be in optimum learning environments.
There are studies that have been done on noise levels in classrooms. Students may be hindered from hearing the teacher if the noise level of an HVAC unit is too loud. There are also studies and debates on how much ventilation air is acceptable. Without proper ventilation, the IAQ may reach the point of restricting learning abilities of the students. Without proper ventilation, the CO2 levels in the classrooms may rise to a point that the students become tired and are less able to learn.
