The Energex Energy Management System

Using a combination of infrared occupancy sensors and a switching control microprocessor, the Energex energy management control system knows when a room in your building is empty for more than 30 minutes.

Once triggered, the energy saving controls switch into ‘Conservation’ mode in the empty room until an individual returns – reducing energy waste and utility costs.

When occupants return to the room , the energy management control system returns room temperature to the occupant’s preferred settings.


Every Energex energy management control system is custom designed for each property and specific HVAC unit, and interfaces with any cooling, heating and ventilation system, including:

  •     PTAC (Packaged Terminal Air Conditioner)
  •     PTHP (Packaged Terminal Heat Pumps)
  •     Baseboard heaters
  •     VAV Boxes
  •     FCUs (Fan Coil-Based Units)
