Feasibility of a Unique Skylight Design for Day and Night Illumination of a Large Volume Room

The feasibility of a unique daylighting approach using a skylight with clerestory windows, also known as a roof monitor, and an outdoor lighting array will be evaluated. The design will illuminate a room 100 feet wide, 100 feet long and 75 feet high, equivalent to a large auditorium located at 40 degrees north latitude. Comparisons will be made to flat skylight wells for the same volume. The design will be shown meet lighting requirements that satisfy Illuminating Engineering Society of North America (IESNA) standards for day and night for tasks of low contrast and small size (i.e. criteria F). The design will be tested with AGI32 version 1.7 software created by Lighting Analysts, Inc of Littleton Colorado. Results will show the unique skylight meets IESNA criteria F during the daytime with an assist by external lighting as daylight is reduced by the setting sun.
