Models for Generating Daylight and Sunlight Availability Data for the United States

摘要

The exteroir illuminance level and the frequency and duration of sunlight are important elements in the design, analysis, and evaluation of daylighting systems in buildings. The daylighting laboratory of the Solar Energy Research Institute (SERI) is establishing daylight and sunlight availability data for select US cities. An overview of the mathematics and a sample of the daylight and sunlight availability data are presented. (ERA citation 08:001878)
