Daylighting based parametric design exploration of 3D facade patterns

Abstract

A building $fa\varsigma ade$ plays an important role in reducing artificial lighting by introducing natural light into the interior space. A majority of research and current technology heavily focuses on the optimization of window properties such as the size, location, and glazing with the consideration of external shading device, as well as the building wall in order to obtain an appropriate natural lit space. In the present research, 3-dimensional enclosed approach that can replicate the conventional $fa\varsigma ade$ ade is proposed. It explores two objectives, daylighting performance and electricity generation, by means of paramedic modeling and simulation based multi-objective optimization method. The study was simulated under the environmental setting of the geographical location of Incheon, Korea without any urban context. Using the proposed methods, optimal solutions were derived and investigated based on the achieved daylighting and generated electricity. The generated 3D $fa\varsigma ade$ performed better than the optimized 2D facades in both objectives and it is proven that it is statistically significant.
