Performance-based design designates the design process where performance index is the key to generate geometry. In this method, the geometry modification is connected to computational simulation processes and an optimization process is associated with the specific design problem. This work addresses the design of solar control elements, which have problems associated with the design program formulation, interoperability and slow computer simulation processes. The objective of the paper is to present a simplified model for fast optimization processes of solar control solutions based on thermal performance and daylighting requirements for the whole year. The multi-criteria optimization model presents three performance indexes: solar radiation in the window plane in hot periods, UDI (Useful daylight illuminance) and area of the shading devices. The computational model is based on the Radiance three-phase method that was up to 10 times faster than Daysim. The process uses parametric modeling through Grasshopper and presents a solution sensitive to complex geometries and choice of glass based on to assist the performance-based design process.
