Abstract
A design aid tool for testing and development of daylighting systems was developed. A
simplified ray tracing software was programmed in Lisp for AutoCad. Only fully
specularly reflective, fully transparent and fully absorbant surfaces can be defined in the
software. The software is therefore best suited to evaluation of light transmission through
specularly reflective daylighting systems. A graphic and numeric display of arrays for
each incident angle aids the user in the ray tracing analysis. The results are automatically
written to a text file for easy import and analysis in a spreadsheet.
