Abstract
The use of generative design has been suggested to be a novel approach that allows designers to take advantage of computers’ computational capabilities in the exploration of design alternatives. However, the field is still sparsely explored. Therefore, this study aimed to investigate the potential use of generative design in an architectural design context. A framework was iteratively developed alongside a prototype, which was eventually demonstrated in a case study to evaluate its applicability. The development of a residential block in the northern parts of Sweden served as the case. The findings of this study further highlight the potential of generative design and its promise in an architectural context. Compared to previous studies, the presented framework is open to other generative algorithms than mainly genetic algorithms and other evaluation models than, for instance, energy performance models. The paper also presents a general technical view on the functionality of the generative design system, as well as elaborating on how to explore the solution space in a top-down fashion. This paper moves the field of generative design further by presenting a generic framework for architectural design exploration. Future research needs to focus on detailing how generative design should be applied and when in the design process.
Highlights
The challenge for building designers is increasing as the act of balancing multiple requirements and needs imposed by clients and regulations on cost, space, esthetics, and sustainability becomes harder.Meeting these requirements and needs can require novel design solutions and expanding the design’s solution space beyond that of previous designs
The study in this paper first set out to develop a framework for generative design that could later be applied to the residential block case
This paper contributes by developing a framework for generative design and evaluating its potential through a demonstration using in the real-world case of residential block development
Summary
The challenge for building designers is increasing as the act of balancing multiple requirements and needs imposed by clients and regulations on cost, space, esthetics, and sustainability becomes harder. Meeting these requirements and needs can require novel design solutions and expanding the design’s solution space beyond that of previous designs. This process can involve both exploration and exploitation, depending on the project situation and the capabilities of the design team. The interest lies in probing an extensive set of solutions to find interesting regions within a design’s solution space. The goal of optimization is to find an optimal solution
