The reliable detection of CO2 is key for demand controlled ventilation (DCV) in buildings, which allows for energy savings up to 30%. Presently, optical detection methods are only in use for a small percentage of building ventilation systems due to the relatively high cost of these sensing systems. A reliable low cost CO2 sensor would allow for widespread use of DCV. Siloxanes are particularly suitable for the detection of CO2 due to their ability to...
