Co-evolutionary Building Design Simulation for Structural Optimization with Facade Openings
State-of-the-art MDO approaches mainly apply pareto frontiers and/or weighted sum methods for detailed optimization problems; nevertheless, these approaches can be too restricted for optimizing conceptual building design. Namely, these approaches start from the (implicit) assumption that design search spaces do not change over time; they cannot generate building design alternatives that were not defined prior to the start of the process. However, design requirements evolve and are not defined in advance (Abraham & Jain, 2005). Maher (2000) developed a co-evolutionary model that enables interaction between two design search spaces, so requirements can evolve.
During this final colloquium two alternative procedures are presented for structural optimization via simulation of co-evolutionary design processes of conceptual building spatial design. Both procedures generate building spatial design representations with facade openings: (1) generates a new pattern of facade openings every simulation cycle; and (2) initializes facade openings only once at the start of a simulation. The results of a parameter study with these alternatives show that facade opening patterns can contribute to building spatial design optimization regarding the minimization of total strain energy.
