Dec. 8, 2011: Demand-Controlled Ventilation Expected to Boost Sensor Demand

WELLINGBOROUGH, United Kingdom — IMS Research’s latest report, “The EMEA and Americas Markets for Building Automation Controllers, Software and Sensors - 2011 Edition,” forecasts double-digit growth, in shipments, of sensors used for demand-controlled ventilation in buildings over the next five years.

Buildings are increasingly becoming air tight which causes a reduction in the air quality, notes the report. Higher levels of carbon dioxide (CO2) can cause drowsiness and create an inefficient working environment. Most traditional ventilation systems ventilate for the maximum capacity of the room whether occupied or not. By using sensors to determine the number of people in the room, the ventilation system can ventilate appropriately and efficiently.

William Rhodes, market analyst at IMS Research, said, “Demand-controlled ventilation (DCV) is not a new phenomenon but has certainly seen a substantial increase in usage over the past 18 months. As governments and businesses look to generate energy savings, it is likely that DCV will continue to gain traction in the coming years and become the de facto standard for ventilation systems.”

The most common building automation sensor used for DCV is CO2. IMS Research estimates over 850,000 CO2 sensors were used in building automation systems across EMEA (Europe, Middle East, and Africa) and the Americas in 2010. The use of CO2 building automation sensors for DCV is forecast to see double-digit growth over the coming five years. However, some vendors have started to advocate the use of volatile organic compound (VOC) sensors as an alternative to CO2 as an efficient method of DCV.

Rhodes said, “There are definite advantages of using VOC sensors for DCV. VOC sensors can pick up odors and smells that CO2 would have otherwise missed. However, following extensive research, the general industry consensus is that VOC is an expensive solution and that it is not as effective as CO2 for DCV. VOC sensors are likely to be increasingly used for DCV, but mainly installed in kitchens and within or around toilets where they can detect organic compounds, including odors and smells.”

The 2011 report indicates that although steady growth is forecast for building automation temperature, humidity, pressure, and occupancy sensors, growth from air quality sensors will be much faster over the coming years.
