This report documents the development and use of the graphic module LITE, a subsystem of the Computer-Aided Engineering and Architectural Design System CAEADS. LITE was developed to assist U.S. Army Corps of Engineers USACE in-house lighting engineers in performing the required analysis during the concept design phase. The program can do Illuminating Engineering Society IES Zonal Cavity calculations internally and, in addition, can build a Conservation of Electric Lighting CEL-1 input deck for comprehensive daylighting studies. Also described is the LCHG program which was developed to maintain the luminaire data base file used by LITE for illuminance calculations. The LCHG program relies on textual rather than graphic interaction with the user. The data base is independent of any other project and can store an unlimited number of luminaires. The program is written in FORTRAN 77 and uses Tektronix 4109, 4014, and 4113 terminals of graphic representations. It is to be field-tested on selected USACE DistrictDivision Harris computers beginning in early FY87.
