Abstract
This research explores the applicability of a performance oriented design approach for form exploration of double skin tower structures inspired by cellular morphologies. Taking advantage of computer aided design and simulation this paper explores the structural and environmental potentials of using Voronoi space divisions in conception of double skin facades for tower structures. The geometry of the double skin structure is created by parametric modelling following the principles of cellular division. Optimization software is employed as a genetic based tool for exploration of design alternatives. The software combines parametric modelling, finite element performance simulation, and a genetic algorithm coupled with database storage of solutions. A SQL database is used to store all of the evaluated design alternatives. The exploration of desired solutions is then performed through database sorts and queries, pallet of well performing design alternatives are generated through the exploration process.
