“…The project cost refers to the costs incurred by all the professions and all the construction stages associated with standard modules and the modular construction, including, but not limited to the manufacturing cost and the transportation cost, the land cost, the foundation cost and the on-site connection cost (Almashaqbeh and El-Rayes, 2021). Since the project cost differs from project to project, the estimation of the project cost can be made by taking advises from engineers and construction workers.…”

“…In some research, the project cost of modular buildings could be break down into various cost categories from different perspectives of design professions and construction stages, i.e. the cost of land, manufacture, transportation and crane lifting (Minunno et al, 2020;Almashaqbeh and El-Rayes, 2021). The cost of land varies greatly and is affected by factors such as neighborhood, soil quality and so on.…”

“…However, user interactions are highly dependent for devising topology rules and assessing alternative solutions. Secondly, the detailing design system of modular construction provides each module unit with attributes of economical features (Minunno et al, 2020;Almashaqbeh and El-Rayes, 2021) and engineering requirements from downstream production (Nauata et al, 2020;Jensen et al, 2012;Xu et al, 2020). However, cost optimization is not adequately explored if the features and requirements are not coordinated with the topology design system (Watson et al, 2022).…”

PurposeThis paper aims to propose a generative design method combined with meta-heuristic algorithm for automating and optimizing the floor layout of modular buildings using typical standardized module units, which are the room module, the corridor module and the stair module.Design/methodology/approachThe integrated framework involves the generative design method and optimization for modular construction. The generative rules are provided by geometric relationships and functionalities of the module units. An evaluation function of the generated floor plans is also presented by the combination of project cost and cost penalties for the geometric features. The multi-population genetic algorithm (MPGA) method is provided for the optimization of the combination of costs.FindingsThe proposed MPGA method is demonstrated fast and efficient at discovering the globally optimal solution. The results indicate that when the unit price of modules is high, the transportation distance is long, or the land cost is high, the layout cost, which related to the symmetry, the compactness and the energy is tend to be lower, making the optimal layout economical.Originality/valueThis paper presented an integrated framework of generative floor layout and optimization for modular construction by using typical module units. It fulfills the need for automated layout generation with repetitive units and corresponding assessment during the early design stage.

“…However, there exist only a few studies that focus on space organization. Most of them focus on energy performance optimization [48], nature-inspired interiors [49], automatic generation [50] or cost reduction [51]. These studies represent an important step in the achievement of passive building energy and comfort optimization, however, most of these studies concentrate only on layout development, without considering the complete and systematic space arrangement and as an effect the building body shape typology.…”

Algorithmic Generation of Building Typology for Office Building Design

Numerous office building design optimizations are in international research to reduce energy consumption, optimize costs and provide optimal comfort. However, there is a lack of knowledge on the effects of geometry and space organization. This study deals with space organization problems and searches for all possible optimal building space structure configurations in terms of energy and comfort parameters using a mathematical algorithmic method. The methodology is based on the formulation of feasible architectural rules and their translation into an algorithm that can generate 2D floor plans satisfying all boundary conditions. In the framework of an exemplary modeling procedure, a 4-story office building geometry generation was carried out, resulting in 17-floor plan versions and 7 different building geometries. The resulting building shapes were classified by energy-related geometry parameters (envelope surface/useful area) for the future step of the research, where the cases will be compared with the help of building simulations. With the help of the method, it was possible to significantly narrow the search space, but future improvements are needed for faster work for wider applicability.
