Lighting is responsible for no less than approximately 40% of a building’s energy consumption. By using it more efficiently, you can save a lot!
The following possibilities are also available to users of Eleqtron lighting controls and presence detectors to work even more efficiently with less energy:
- It is very easy to save electricity by dimming the lighting based on daylight. This is already possible just with the stand-alone presence detectors with integrated daylight measurement. Dimming by 10% will easily save you 20% of the energy consumption!
- Usually, you can easily and cheaply switch the central lighting on and off automatically with the alarm panel. This can be done by connecting the panel to the lighting controls.
- Benefit even more from the features of Qneqt presence detectors. For example, PRM type presence detectors can be set to a threshold value on the basis of the light intensity measured. Subsequently, the detector switches off the lighting as soon as the threshold value is exceeded (sunny/clear weather). That makes it even more energy efficient! Setting the detection sensitivity changes the sensitivity of the detector.
High detection sensitivity means that the lighting is switched on quickly, with the slightest movement. With low sensitivity, more movement is necessary to activate the detector.
Lighting can be switched off more quickly if there is no activity in the space by decreasing the time-out setting of the presence detector. Please note that this will increase the number of switching cycles!
- With ‘smart’ switching, you can save a lot on the energy costs for lighting in a parking garage. For the most efficient control, the fixtures must be wired alternately, distributed over different strands. If this is done, a 50% – 50% control can be set on odd and even days. The contacts for each section (control address) can then be switched on and blocked, so that they do not ‘react’ to a timer control during maintenance and/or events.
- In combination with PIR type (Passive Infrared Detection) presence detectors, it can easily be avoided that the lighting switches on when this is undesired. These detectors work on the basis of heat displacement. Failures may e.g. occur if there is not enough distance between the detector and the ventilation grate. With a minimal grate opening, convection flow may occur causing the detectors to be activated unnecessarily. We recommend increasing the distance between the detector and the ventilation grate. Other ‘heat generators’, such as freestanding heating elements, improperly closed windows, photocopiers, scanners and other equipment, can cause the same fault. Positioning this equipment differently will probably resolve the failure.
