|CARBON DIOXIDE SENSOR USAGE IN THE POWER CENTER FOR THE
PERFORMING ARTS| Carbon dioxide (CO2) sensors can be installed
in areas that have infrequent or irregular occupancy patterns,
such as auditoriums and classrooms. The sensors allow the
ventilation system to be controlled by the concentration of CO2
present in the space, thereby reducing the amount of ventilation
required during unoccupied times. As the space becomes occupied,
the sensors will detect an increase of CO2 and adjust the amount
of outside air needed. CO2 sensors, as well as other energy
saving equipment, were installed in the Power Center for the
Performing Arts on the University of Michigan's Ann Arbor Campus
in 1994. Overview of Procedure The system is designed to work
efficiently in large open spaces including auditoriums,
classrooms, or conference rooms. Placement of sensor locations
within a given space is critical for the system to work
properly. If the sensors are not located correctly, fluctuations
in temperature and overall comfort w
