Daylighting and ramps are, indeed, good design — respectively, they save building owners money by conserving energy and allow access to people with disabilities. So is centrally locating a generously sized grand staircase that encourages able-bodied people to walk rather than ride an elevator — it could be one of the key weapons in the battle against obesity.
With regard to active design, SCUP member Jim Kalvelage of Opsis Architecture is quoted: "Some of it we do naturally — it's kind of how we think about stuff. I can think of a lot of great examples of what it means in terms of the interconnection of indoor and outdoor space, or the design of stairs that make you want to go up the stairs instead of taking the elevator. One of the very first recreation centers I worked on was a two-story building on a sloping topography, so it used a ramp to move between floors so that people were actually interacting with the building instead of coming down an elevator."
