Electronics From GreenBuild
LEDs, lighting control, green screens and occupancy sensors shown at green building show.

Most of the electronics products from the Greenbuild in Chicago focused on lighting and shading applications. Here are the highlights.

Philips Solid-State Lighting Solutions showed an LED downlight, the eW Downlight SM Powercore, which will be available in March. (It was also featured in the previous entry, “LEDs a Near Fixture.”) The 7.5-inch square light and fixture is less than 2 inches thick and produces 600 lumens of light in 2700K or 4000K temperatures. The product is still in development, but I’m told the energy consumption will probably be in the 12 to 15-watt range.

Lutron’s new Grafik Eye QS improves upon its previous six-load controllers with a better button layout and pinpoint control of dimming, but also built-in inputs for occupancy sensors and three zones of Lutron’s Sivoia shading systems. A built-in astronomical clock helps with scheduling automated shade or light control to help save energy costs. Cost is about $1,000.

Draper has introduced a line of Greenguard-certified projection screens that emit low volatile organic compounds (VOCs) that can affect breathing and health. The screens are certified by third-party green-product certifier Greenguard Environmental Institute. The screens are available in four fabrics: Matte White, M1300, HiDef Gray and High Contrast Gray, and won’t be priced at a premium over existing screens, says Draper Green Buildings Coordinator Clint Childress.  Draper is absorbing the higher costs of producing these screens, which Childress says stems largely from the certification process. Draper has also launched its new green website,

Lightolier Controls showed its IntelliSight Occupancy Sensor, which can easily replace a standard switch in a bathroom, closet, attic, garage, or other space where a light is apt to be left on. It features manual or automatic on, and automatic off options from 30 seconds to 30 minutes. The IntelliSight can service a 4,000-square-foot open area, and has a sensing technology that can learn from mistakes, so it won’t turn on or off lights automatically. It can handle loads of 5 watts to 2,000 watts. Cost is $60.

Duo-Gard showed its decorative LED IllumaWall panels that diffuse small LEDs with polycarbonate and resin panels. (Also covered in “LEDs a Near Fixture.” The panels can be used in entryways, clerestory applications, and decorative light walls. The panels aren’t cheap at about $6 per square foot, before you add the LEDs.

Lucid Design Group markets a very cool and slick Digital Dashboard that can compute your energy savings for systems such as solar and other sources. We featured it in our Green Home of the Year, though the system is intended to monitor commercial buildings like apartment complexes. It’s not intended for the residential market yet, but it may be in homes quicker than the company thinks.

Wattstopper/Legrand, MechoShade and Somfy Systems were also exhibiting at the Greenbuild Expo. Wattstopper also produces occupancy sensors and lighting controls, MechoShade does window treatments and a green EcoVeil shade. And Somfy Systems produces motorized window and window treatment systems.
