Within contemporary architecture, the art of daylighting design ? despite its many recognized advantages in comparison with electric lighting ? still encounters skepticism, primarily because it is usually developed and articulated more intuitively, rather than technically. Innovative daylighting applications have added sparkle and interest to buildings. The sun?s rays have been captured to create magnificent plays of forms in light. People perceive daylight as an essential element of life. But architects, lighting designers, and clients alike, often underestimate the importance of daylight for human well-being and energy performance of buildings. It is undisputed that modern architecture requires a creative, but well-planned approach that allows for the integration of many aesthetic, technical, and social or historical factors. If integrative planning is neglected, especially in the early phases of the design process in which the cornerstone for good daylighting design is laid, problems may arise for the building user later on, resulting in reduced occupant comfort, and higher expenses for installation and operation of environmental control or HVAC systems. Architects, lighting designers, engineers and clients are therefore advised to consult with each other at the earliest possible time to explore all potential alternatives for cost- and energy-effective building design. This brief discourse describes some of the fundamental issues for daylighting design and provides tools and ideas for approaching daylighting design with an open mind and an appreciation for basic human needs.
