Before considering artificial lighting, all designs – zero energy or otherwise – should make the most of natural lighting opportunities. After natural lighting has been optimized, identify horizontal work surfaces where task lighting is needed, such as kitchen counters, bathroom vanities, hobby areas, and offices. Next identify specific architectural elements or artworks that require accent or focal-point lighting. Once those specific locations have the proper lighting, consider general or ambient lighting to fill in additional spaces. Indirect lighting using valances and wall sconces can be an effective and attractive way to accomplish this.
