Performance assessment of demand controlled ventilation controls concerning indoor VOC exposure based on a dynamic VOC emission model [PDF]

open access: yes, 2019
The performance assessment of ventilation systems often focusses only on CO2 and humidity levels. The indoor Volatile Organic Compounds (VOC) emissions of building materials or other products is thereby overlooked.
