Energy savings and exposure to VOCs of different household sizes with a smart ventilation system

Assessment methods to assess smart ventilation, in most countries focus only on comfort as criteria for the indoor air quality (IAQ), (Guyot et al., 2019). This is an issue as in doing so, pollutants that are known to cause harm to the human health are not taken into consideration while the exposure to VOCs will be elevated if the smart ventilation system lowers the ventilation flowrates to save energy (De Jonge and Laverge, 2021).

Metal Oxide Semiconductor sensors to measure Volatile Organic Compounds for ventilation control

The application of Metal Oxide Semiconductor (MOS) sensors measuring Volatile Organic Compounds (VOC) gains increasing attention in the ventilation community because of their low price and claimed ability to supplement or even substitute CO2 sensors for demand controlled ventilation (DCV). Even though there are many “Indoor Environmental Quality” meters available on the market, in which these sensors are used, the amount of scientific studies focused on their reliability and applicability is still limited.


It is well known that volatile organic compound (VOC) emissions from construction materials and officeappliance occasionally have influence on human health. It is a social request that manufacturersreduce VOC emissions from their products. To measure emissions from materials, a high-precisionchamber is required that can control environmental conditions such as ventilation, temperature,humidity, air flow, and VOC concentrations.
