Ambient air quality, the building envelope and its ventilation system determine a consider­able part of the indoor air quality (IAQ). But also indoor sources such as building materials and consumer products used indoors, affect the quality of the indoor environment. VITO identifies and quantifies the indoor sources and makes an accurate risk evaluation out of this.

But measuring indoor air quality and ventilation rates often requires eco-unfriendly substances or complex and expensive equipment. Luckily, Sarah Lima Paralovo (PhD VITO/UGhent) is developing a simple method to measure ventilation rates.
