Good daylighting strategies--the use of natural light to brighten up a home's interior--are increasingly in demand, especially for builders who work in urban and suburban neighborhoods where trees and nearby buildings often obstruct sunlight. Daylighting also is fundamental to green building: By limiting the need to turn on lights during the day, a well-designed, daylit building is estimated to reduce lighting energy consumption by 50 percent to 80 percent, according to the U.S. Green Building Council (USGBC).

Products that improve natural lighting definitely piqued reader interest this year: A translucent, insulated wall panel (No. 50) and three multi-panel glass door systems (Nos. 12, 74, 75) show up on the Top 100 list. In addition, the ODL remote-controlled Solar-Powered Dimmer (No. 86) helps homeowners control daylighting from tubular skylights and Andersen's 100 Series windows (No. 54) feature special glazing to prevent unwanted heat gain.

Technology also continues to weave its way into windows and doors with innovations that address convenience, security, and energy efficiency. Case in point is No. 52, the Schlage LiNK wireless-controlled door lock system that allows homeowners to control whole-house automation via the Internet. --Jennifer Goodman
