Lighting And Daylighting

strategic design of a structure to optimize the amount of light required by a space in the daytime, and, by extension, to optimize temperature and airflow. Successful daylighting design often requires the use of many geometric concepts, including lighting power density, illuminance levels, contrast ratios, window to wall ratios, ceiling to skylight area percentages, and reduction in glare; it also includes technology in shades and drapes East- and west-facing windows should be avoided, as they can cause glare and maximize heat in summer and minimize it in winter.
