Determinants of Lighting Quality I: State of the Science

Lighting quality may be the most talked about but least understood concept in lighting research and lighting design. Interest in lighting quality is currently high, judging from the occurrence of sessions and workshops a almost all major conferences (e.g., at the Commission Internationale de l'Éclairage session in New Delhi, India, in November 1995; at the Chartered Institute of Building Services Engineers 1996 National Lighting Conference in Bath, England, in March 1996; and at LIGHTFAIR INTERNATIONAL, in San Francisco, May 1996). The introduction of building energy codes and pressure to increase energy-efficiency has re-opened an old debate.
