Thinking about upgrading some of your outdated lights? Good idea. But if you really want to cut lighting expenses, you need to look at the whole picture. That means combining lighting and lighting controls.
Thinking about upgrading some of your outdated lights? Good idea.
New light sources are finding their way into all aspects of indoor and outdoor lighting and they offer huge savings. Digital light sources (LEDs) use 50-80 percent less energy to produce the same amount of light as incandescent or CFLs.
But if you really want to cut lighting expenses, you need to look at the whole picture. That means combining energy efficient lighting and energy conserving lighting controls.
Savings by the numbers:
The US Department of Energy estimates that upgraded lighting systems could save $50 billion in needless energy costs each year1.
In 2010, only 1% of commercial buildings used facility- wide lighting controls2.
Multiple lighting control strategies — cut energy consumption by as much as 70%.
Task Tuning — Average energy reduction: 36%
Tailors light to the task performed in that space so the space isn’t over-illuminated for the work performed there.
Daylight Harvesting — Average energy reduction: 28%
Uses light sensors to measure natural/ambient light and automatically adjust electric lighting based on a pre-set target.
Personal Controls — Energy reduction up to 25%
Users control a dimmer switch to adjust lighting levels for their comfort.
Occupancy and vacancy sensing controls — Average energy reduction: 24%
Sensors regulate lighting by detecting motion in a space. An occupancy sensor automatically turns lights on when a person enters a room and off when they leave. A vacancy sensor automatically turns the light off when a room is vacant. When a user enters the room, they have to manually turn the lights on.
Scheduling — Energy reduction up to 40%
Automatically adjusts lighting, equipment or other building management systems based on the time of day or astronomical event.
