Additional future work will involve the expansion of the knowledge-base to include daylighting performance metrics such as illuminance on vertical planes, glare, or solar thermal gains. The addition of such metrics will allow users to obtain more complete information about daylighting performance and will aid in the design of more comfortable environments. The addition of these new metrics will necessitate further investigation of search or optimization methods for use within the expert system, particularly since illuminance and glare goals may conflict. Validation of the method over a variety of geometrical cases and against traditional optimization methods will also be completed.
