1. ENERGY EFFICIENCY
The desirable, all-natural (and extremely hard) way to light an office
Chris Meek is a Seattle architect who tries to go all day without turning on a light bulb. It sounds like a joke -- get by on sunlight in a cloudy city -- but he pursues the goal with a single-minded, almost obsessive determination. Meek, 43, is the director of the University of Washington's Integrated Design Lab, and one of a small brain trust of architects and researchers who are trying to return daylight to its role as a chief source of illumination for the world's office buildings.
