Studies indicate demand-controlled ventilation offers energy savings of up to 70% by
ensuring constant levels of indoor air quality and low operating costs. With Siemens
sensors, optimized indoor air quality and maximized energy savings are achieved by
measuring CO
2
and VOC (Volatile Organic Compounds) and implementing demand-
controlled ventilation strategies.
Like all Siemens sensors with active output signals, the indoor air quality range has a
built-in self-monitoring capability for all measuring variables. The non-dispersive infrared
CO
2
sensor experiences less than 1% drift per year for the first two years of operation and
negligible drift thereafter, so no calibration is necessary. In addition, the sensors can be
switched to a special service mode, offering additional convenience for project
development and commissioning.
These sophisticated sensors are housed in an aesthetically appealing modular housing to
meet the specifying recommendation of architects and eliminate the need to install
multiple room sensors close to each other.
