The U.S. Department of Energy (DOE) has just completed its second public comment period for the "2010 Energy Star for Windows, Doors, and Skylights Revised Draft Criteria and Report," pushing the window and door industry further toward tighter energy performance requirements for windows, doors, and skylights that bear the Energy Star label.

A new way to bring natural light into interior spaces, Huvco’s Parans Fiber Optic Skylight system collects sunlight through lenses on outdoor panels (shown), then funnels the light through optical cables to luminaires. The system’s daylight collectors mount on roofs or façades. The thin, flexible optical cables, which are routed through walls and ceilings, have high light transmission that lets sunlight efficiently reach far into buildings; the luminaires are designed to recreate the feeling of sunlight. Hybrid luminaires that combine natural light and electric light are available. 800.832.6116. More
The solar-powered dimmer for the manufacturer’s Energy Star-qualified tubular skylight allows users to control the amount of light entering through the skylight and does not require hard-wiring. The solar panel charges four AA NiMH batteries that power a three-button control that operates the dimmer. The control also serves as a two-LED nightlight. 800.635.4968. More
SageGlass electronically tintable skylights allow control of the amount of light and heat that enters a room. Applying a safe, low-DC voltage via a control switch, remote, or automatic timer causes the electrochromic layers on the skylight to darken, and reversing the voltage polarity causes the layers to lighten. The skylights have a whole-unit U-factor of 0.49 and an SHGC of 0.10 when the skylight is dark or 0.47 when it is clear. SageGlass is available in select sizes of model FS and model VSE skylights, which are deck-mounted and have wood frames, as well as in select sizes of the aluminum FCM and wood VCE skylights, which are curb-mounted. The skylights are Energy Star–qualified. 800.888.3589. More
Anything that makes it easier for pros to incorporate natural light—a key component to any green home—gets our attention. Huvco’s fiber-optic system takes daylight to the darkest of places, illuminating interior rooms, closets, and bathrooms. Optical lenses on exterior-mounted solar panels capture sunlight, then channel it through thin, flexible, fiber-optic cables to interior rooms. Luminaires within the room recreate the feeling of sunlight. Also available are hybrid luminaires that combine daylight distribution with an electric light for times when the sun isn’t shining. According to the company, exchanging half a building’s electrical lighting for this system can lower energy costs 20% to 25% and greenhouse gas emissions 10% to 15%. 800.832.6116. More
