Fresh Air Ventilation System for Kindergartens and Schools

Lack of ventilation causes bad indoor air quality. In order to build a better environment, kindergartens, schools and universities should choose a good fresh air ventilation system. The performance standard for school buildings is based on the requirement to control the carbon dioxide that results from the respiration of occupants. This is the key indicator of ventilation performance for the control of indoor air quality. Therefore ventilation standards requires that the concentration of carbon dioxide in all teaching and learning spaces, when measured at seated head height and averaged over the whole day should not exceed 1500ppm. The whole day refers to normal school hours (i.e. 9.00am to 3.30pm) and includes unoccupied periods such as lunch breaks. Airwoods has rich experience in the fresh air ventilation system design of kindergartens, schools and universities. Following are some classic cases for reference.
