Digital Addressable Lighting Interface

Around 40% of the energy consumed globally is related to buildings. Artificial lighting consumes a significant part of all electrical energy consumed. In offices from 20 to 50 percent of total energy consumed is due to lighting. And most importantly, for some buildings over 90 percent of lighting energy consumed can be an unnecessary expense through over-illumination.

In most cases, someone switches on and off lights at the start and at the end of the day. Other more sophisticated buildings (few of them) implement some sort of automatic control of lighting making this switching on and off by automatic control based on presence detection or calendar/hourly basis. And other even more sophisticated ones (very few of them all) implement really effective lighting control providing just the appropriate light level in any part of the building at any time, having in consideration many variables like daylight coming from outside, presence of people in each area, the required light level according to workplaces, etc.
