Daylighting Brings Big Savings to Code Compliance

Daylighting Brings Big Savings to Code Compliance - Leviton Blog

What do ASHRAE 90.1, Title 24 and IECC 2012 energy codes and standards all have in common? They all require daylighting!

Daylighting is one of the best methods of lighting control—not only does it save energy by utilizing natural light in a space, it also makes buildings more pleasant places to visit and work in! The cost and satisfaction benefits of daylighting are outstanding, and the required energy techniques are easy to implement with state-of-the-art Leviton solutions.

Daylighting is an energy management technique that reduces overhead lighting use by:

  • Utilizing the ambient (natural & artificial) light present in a space
  • Dimming or switching OFF lighting when sufficient ambient light is present or when the space is unoccupied
  • Utilizing zones to stagger the dimming and switching of lighting loads depending on their distance from ambient light sources, such as windows and skylights

  • Health benefits of correct lighting

Make your building a better place to be AND earn continuous energy savings? It’s no wonder that this excellent technique is driving energy codes!

Want to see daylighting in action? Check out our interactive demo, which shows the capabilities of the Integrated Room Control (IRC) in commercial and education applications.

The IRC is a daylighting workhorse designed to make energy code compliance a snap. This easy-to-install, room-in-a-box solution comes packed with an entire suite of capabilities that meet codes and slash energy bills:

  • Daylighting: Automatically adjusts electric light levels based on the amount of daylight in the space
  • Dimming: Delivers multiple light levels other than full-ON and full-OFF for more pleasant, flexible and economical lighting
  • Demand response: Reduces lighting loads during peak levels of energy use, which are more costly
  • Plug load control: Automatically switches receptacle outlets OFF based on occupancy sensor signals to prevent unnecessary power draw
  • Partial-ON control: turns lights ON partially via manual switch or occupancy sensor when a space is occupied
  • Partial-OFF control: automatically reduces lighting in a space by at least 50% when a space is occupied
