Controlled Ventilation
Ventilation is an important part of maintaining a comfortable,
healthy, productive environment for people. Improper
ventilation can have a negative impact on occupant health
and performance, increase the risk from litigation, and/
or waste energy. Demand-controlled ventilation using CO2
sensors prevents energy losses from over-ventilation while
maintaining indoor air quality. The most energy savings
potential is in buildings where occupancy fluctuates during
a 24-hour period. Numerous organizations now require and/
or recommend CO2-based ventilation control in different
commercial HVAC applications. Some utility companies also
offer rebates to building owners for installing CO2 sensors.
Wall mount sensors are used to control a specific area such
as a conference room, classroom, meeting hall, etc. The
Telaire 8000-R Ventostat series are easy to install and have a
clean, modern look that suits most indoor environments.
