Common Energy Saving Control Methods for Public Facilities

A enclosed public room is sometimes occupied and sometimes vacant. They are unlike large open public spaces and instead require the use of sensors and switches for the purpose of local control. Below are some of the more common methods applicable to such spaces, and which also the specialty of DAE. Set up simply requires a tablet computer with the appropriate interface converter.

  1. Manual on, sensor auto off – for places such as reception rooms, reading rooms, small offices, study rooms, labs, etc.
    1. Wall switches are installed that can be used by the occupant to turn the lights on or off as needed.
    2. If the occupant leaves but forgets to turn off the lights, the sensor will automatically turn the lights off after 10 minutes (adjustable) of not detecting the presence of the occupant.
  2. Manual on, delay auto off – for hallways, stairwells and other passageways.
    1. Multiple push button wall switches are installed along the length of the passage, the user can turn the lights on or off from any of these switches.
    2. If the lights are not turned off manually after 5 minutes (adjustable) the lights will automatically be turned off by the smart switch.
  3. Multiple access – large storage rooms, warehouses, and large data centers
    1. Multiple push button wall switches are installed in convenient areas that allows the user to turn the lights on and off.
  4. Centralized control during peak hours, local switch control during off-peak hours
    1. Peak hours – the lights are forcibly controlled from the control center and the local wall switches are disabled.
    2. Off-peak hours – The control center relinquishes control to the local wall switches, allowing the user to turn the lights on and off as needed.
  5. Centralized control during peak hours, local sensor control during off-peak hours
    1. Peak hours – Depending on whether the local area is daylit or not, the control center will then either forcibly turn the lights on or off, and the local sensors are disabled.
    2. Off-peak hours – The control center relinquishes control to the local sensors; people come, lights turn on; people leave, lights turn off.
