VAV system indoor air quality considerations for office spaces

This paper discusses indoor air quality considerations for office spaces when using VAV system. that provide various supply air rate according to the space loads, especially in multiple spaces, served by a common air handling unit. The ventilation rate procedure and the indoor air quality procedure (the monitoring contaminant concentration method) are used in order to ensure the indoor air quality. A design solution and ventilation control strategy at the fixed outdoor air rate for indoor air quality is provided.
