MOS VOC sensors gain increasing attention in the ventilation community because of their low price and claimed ability to supplement or even substitute CO2 sensors for demand control. Even though there are many “IEQ” meters available on the market, where these sensors are used, the amount of scientific studi`es focused on their reliability and applicability is still limited.

In this webinar, participants of IEA EBC Annex 68 presented research results, experiences and thoughts related to MOS VOC sensors. The aim of the webinar was to intensify discussion on the topic of low-cost sensors in the ventilation community.

This webinar was jointly organised by the IEA EBC Annex 68: “Indoor Air Quality Design and Control in Low Energy Residential Buildings” and the Air Infiltration and Ventilation Centre. The webinar was hosted by INIVE (www.inive.org).

Presentations & speakers:

• Introduction. Peter Wouters (AIVC, Belgium) & Carsten Rode (IEA-EBC Annex 68, Technical University of Denmark, Denmark)
• Can the TVOC-sensors be used for ventilation control? Nadja Lynge Lyng (Danish Technological Institute, Denmark)
• MOS VOC sensors’ properties and suitability for DCV control: analysis based on laboratory measurements. Jakub Kolarik (Technical University of Denmark, Denmark)
• VOC vs. CO2 controlled DCV: A case study. Jelle Laverge (Gent University, Belgium)
