Tips for Daylighting with Windows:ProvisosThese guidelines cannot answer all questions for all projects, however they aim to address the most frequently raised questions for most projects. These guidelines are primarily applicable to typical commercial buildings with office-like occupancy (includes schools, laboratories and other working environments), standard construction, and windows as the primary source of natural light (skylights are not addressed in this version). These guidelines are primarily applicable to new construction. They may apply to some retrofit projects, if used with caution. These guidelines were developed for California climates and latitudes, however advice may be appropriate in other regions. These guidelines are distinguished from existing material in their how-to focus and their explicit support of design integration. Background material (basic principles, for example) is not included. The design professional is ultimately responsible for all design decisions. The user is assumed to have a basic knowledge of lighting and daylighting principles. Advice is given in a simplified, rule-of-thumb format. More detailed and accurate assistance is best provided by an expert consultant or an advanced computer tool.
