Energy Saving Plan by MRBAS System

The energy savings rate will vary depending on which system you are using in your building. Save energy by designing an optimal system.

We have compared and analyzed power saving rate when applying ON/OFF system, Dimming System, DALI Dimming + individual loudspeaker control system among MRBAS lighting control solutions.

The analysis of the system estimates the hours that employees spend intensively at 10 hours per day, since ON/OFF system can not control individual, it is divided into zones. The dimming system is also designed to control the dimming control by dividing the circuit into zones rather than individual luminaire controls. The DALI Dimming control system was designed as a way to control the individual lighting in office and meeting room, executive room, and to control the dimming by configuring circuits in the window as zones. By using schedule control considering commuting time, cleaning time and lunch time, we can control lighting of the entire area at 50% and 25% of the working time and lunch time. The window control was set so that the illuminance sensor senses the illuminance of the downlight in the window area and controlled 30~70% dimming. In the executive room, meeting room, lounge, etc., is the occupancy sensor and the window side illuminance sensor are installed, and the occupant is automatically detected by detecting the absence of the occupant. The executive room and conference room are set up to enable the SCENE control so that any effect can be produced. In the office area, dimming control is set up by stepping on the individual LED lights by detecting occupant’s absence by applying occupant detection sensor. By setting the dimming control function, the LED lighting intensity is maintained at 80%, and the efficiency is set to be 80% or less. Based on what you set up like above. As a result of comparing and analyzing the energy saving situation, the DALI + Dimming System shows the highest energy savings.
