Ledalite’s Ergolight Office Lighting Reduces Energy Consumption by up to 80%

May 10th, 2009 by  

Building managers and environmental passers-by always scream when they see office lights on in the middle of the night, illuminating someone’s cubicle for hours when they’re not there. Ledalite’s Ergolight Controls System has been designed to take care of that problem, as well as increase office energy efficiency. It’s such a good solution, that it was recognized by the David Suzuki Foundation as one of their climate change solution case studies. Designed to help building designers and architects achieve LEED certification, depending on the set-up, customers can decrease their energy consumption by up to 80%.

Ergolight uses an integrated system of lighting fixtures, sensors and computer software to achieve these eye popping energy reduction results. Using daylight sensors, occupancy sensors and software-based personal dimming controls at each workstation, Ergolight is a pretty active system.

So how does it work? Basically, each fixture is connected to the building’s electrical system and then to one another via network cable. This whole network is then connected to a central control unit that users can interact with through their workstation (i.e. raise or dim the lights).

The real energy savings lie in the integration of daylight savings and occupant sensors into the overall lighting system. The daylight sensor monitors light levels on the desktop and gradually adjusts lamp output to compensate lighting changes throughout the day. The occupant sensor does exactly what you think it does: it turns off lights in areas that aren’t being used. Brilliant!
