Simplified Methods for Generative Design That Combine Evaluation Techniques for Automated Conceptual Building Design

Smart design and construction have emerged as pivotal forces in the construction industry. Numerous studies have been conducted in the realm of design optimization, using artificial intelligence data-driven approaches and optimization theories. This increase in research has sparked interest in generative design, a process that automatically generates algorithm-based design alternatives, thereby reducing human effort and time by a significant margin. The objective of this study was to explore the potential of generative design to boost productivity within architectural practices and reduce redundant and unnecessary tasks for an aging construction workforce. Specifically, it illustrates the process of selecting superior alternatives by generating various three-dimensional layouts, using a generative design methodology. This occurs during the creation of a building layout concept with subsequent partial evaluations. The methodology of this study was mainly divided into four stages: objective setting, design algorithm development, the establishment of evaluation methodology, and the comparison of the results' values. The findings of this study confirmed that the design algorithm and evaluation methodology form a single loop, generating a multitude of design alternatives that satisfy the algorithm designer's evaluation criteria.

Automated summary

Smart design and construction play a crucial role in the construction industry. Generative design has been found to enhance productivity by automatically generating design alternatives based on algorithms, reducing human effort and time. This study explores the potential of generative design in enhancing productivity and reducing redundant tasks, using a methodology that involves generating three-dimensional layouts and evaluating them.
