HVAC SYSTEMS
• HUMIDITY CAN BE ALTERED
• OUTSIDE AIR BE ADDED OR REMOVED
• TEMPERATURE CAN BE ALTERED
• FILTRATION CAN BE DONE
• CO2 CAN BE CONTROLLED

SENSORS
THERMISTORS (20ºC to 24ºC)HUMIDITY SENSORS (50% RH to 65% RH)CARBON DIOXIDE SENSORS ( 450 ppm to
650 ppm)OCCUPANCY SENSORS
(ASHRAE standards)

ENERGY ANALYTICSFault Detection in building systemsContinuous energy monitoring and real time or close-
to-real time alertsIdentifies anomalies and patterns in building data
Where does the data come from??Sensors and Controllers
