TETRA – Leuven (BE)
Analysing a lighting control system
TETRA Research Project – LEUVEN (BE)
The IWT TETRA project, “Analysis of energy savings of three daylight control systems in a school building” by the Catholic University of Leuven (Ghent Technology Campus), is a monitoring project in which long-term practical measurement of energy consumption in ten classrooms was carried out.
B.E.G. is one of twenty partners in the research project. In order to research daylight and occupancy control, B.E.G. products were installed in two areas:
- Heilig-Hart & College, Halle: PD2-KNX occupancy detectors connected with the building control system via the KNX bus. Room usage registered by the occupancy detectors can also be used for other building functions, e.g. control of heating.
- Don Bosco, Haacht: As people often forget to turn off the light in shared rooms, the PD4-M-TRIO-DALI/DSI occupancy detector was installed in one classroom. This detector can control three channels, of which two are dimmable. For classrooms, which generally have a window side and a wall side, this is ideal. The side of the room furthest from the window can thus be regulated to have more artificial light than the window side.
The study showed that intelligent lighting control can save 18-46% of energy use.
