Lighting typically accounts for up to 40 percent of the energy used in commercial buildings. Lighting controls make it possible tc eliminate energy waste through better control of how and when lights are used without affecting employee productivity. A combination of daylighting, occupancy sensors, scheduling timers and dimmer controls can reduce unnecessary use of lighting hy 20 to 90 percent.
Daylighting design is the science of balancing and augmenting natural daylight with electrical lighting. By measuring the distribution of natural light in building workspaces, designers define light zones within buildings that are automatically controlled with daylighting controls. This is an effective way to maximize potential energy savings by leveraging natural daylight when it is available.
Quality, glare free lighting not only reduces energy usage and expense, it improves employee comfort, safety and productivity.
Occupancy Sensors use passive infrared and/or ultrasonic sensing technology to provide cost-effective lighting control that switch or dim lights based on human occupancy. Sensors are a simple yet effective way to make buildings more energy efficient.
Occupancy sensors are most effective in areas with irregular or light employee usage patterns and can reduce wasted energy by 35-45%
Dimmers are used to adjust the lighting output with the dual benefit of providing optimized lighting for employees while using the least amount of energy necessary. Dimmers can adjust lighting over a continuous or stepped range depending on the technology and lighting systems installed.
Dimmers can reduce up to 60% of the energy used per lighting fixture while sill offering an appropriate amount of light.
