The lighting of learning environments is an important focus in designing new schools and renovating older schools. Studies long have shown that appropriate lighting levels and daylighting improve learning; now, climbing energy budgets have spurred school administrators to seek more efficient use of lighting. Electricity rates are expected to rise over the next several years. That makes efficient lighting design and control strategies even more critical. New school designs are taking advantage of rapid improvement in lighting-control strategies and illumination systems, and existing schools can be retrofitted to realize savings. The author discusses three most prevalent energy-saving tactics: (1) increased use of daylighting; (2) maximum controllability; and (3) prudent selection of lighting equipment.
