Lighting Design & Daylighting
Energy-efficient lighting is seriously misunderstood by many in the green building industry. Long associated with CFLs and poorly lit spaces, today’s energy-efficient lighting uses state-of-the-art LEDs, controllers, and optics to direct light just where you need it.
Outdoors, LED streetlamps use advanced sensors and are optimized for maximum efficiency, yet they produce little light pollution that could disrupt local wildlife.
Indoors, LEDs can be integrated into DC power systems via power-over-ethernet cables. The color can be changed to help increase worker productivity, improve patient moods, or mimic natural outdoor light to help maintain our natural circadian rhythms.
New forms of LED and OLED lighting are revolutionizing how we light our buildings.
