Daylighting Analysis and Simulation Tools in Architectural Design - Review of Tools and Compatibility with Architectural CAD Platforms

Purpose: This research is a review of current and past daylighting simulation tools from the perspective of the Architect, one of the key stakeholder in the integration of the science of daylighting into architectural practice. The review is evaluated based on criteria identified through existing literature. First, a review of integration and interoperability with mainstream architectural CAD platform is initiated and second an evaluation of select tools were performed based on a simple simulation task involving a typical classroom. Method: Over fifty daylighting simulation tools are categorized based on its integration and plotted on an “integration matrix” to illustrate compatibility with mainstream architectural software. The matrix is used as a basis to identify daylighting simulation tools for further evaluation. Evaluation of the tools are based on functionality, ease of use, and visualization. Result: Findings include recent increase in available daylighting simulation tools in the form of plug-ins to existing architectural CAD platforms. In addition, the integration matrix provides valuable information to architects and designers in the selection of Daylighting Simulation Tool, one of the key hurdles that designers face in the implementation of daylighting in architectural design practice. Furthermore, the evaluation of the tools provides information in the aid and development of future Daylighting Simulation Tools.
