High-Efficiency Lighting:

Lighting accounts for as much as 10 to 15 percent of the energy used in a typical commercial building. Much of this consumption is unnecessary due to the use of inefficient incandescent bulbs or lights left on in rooms while unoccupied. Available lighting technologies can substantially reduce this energy use without sacrificing comfort or convenience.

Automatic Control for Indoor/Outdoor Lighting:

Activity sensors detect occupancy within a certain area and switch lights off when no movement is detected for a specified period of time. The two types of sensors are ultrasonic and infrared. Ultrasonic sensors detect sound while infrared sensors detect heat and motion.

Outdoor lighting is used by many commercial buildings on a nightly basis for safety, security and aesthetic reasons. Automatic controls such as motion and photo sensors provide the same function while reducing the energy use by as much as 90 percent.

Compact Fluorescent Lamps (CFL’s) vs. Incandescent Light Bulbs

CFL’s are energy efficient alternative to incandescent bulbs most commonly used to light our homes and offices today. CFL’s use approximately 66 percent less energy while providing the same amount of illumination. In addition CFL’s last about 10 times longer for added convenience.

  • Improved comfort; efficient lighting technologies produce less waste heat and thus improve comfort in cooling dominated climates.
  • Lower utility bills; Installing high-efficient lighting in most used fixtures (about 1/3 of all fixtures) in a commercial building will reduce lighting energy consumption by half.
  • More convenient; The life spans of fluorescent and compact fluorescent lamps are at least 10 times longer than incandescent light bulbs. This result in fewer annoying burnt out bulbs and subsequent lamp replacements. This is also beneficial in hard to reach places such as stairwells and rooms with high ceilings.
