An interactive computational approach to 3d layout design of single-family houses by evolutionary algorithms

Sakaryalı, Anıl
Customized design is an important feature for single-family houses (SFH). Differently, current stage of the housing industry is generally limited to the standard houses by tract developments. In this way, design tools for non-expert users can provide a strong alternative to the current mode of house production. Certain generative design tools can provide customized house solutions according to the requirements of occupants. A certain problem in this case is the presented level of interaction for the non-expert occupants. A study on the current generative approaches to non-expert design tools showed that generative approaches present a limited interaction for the user due to the limits of their solution space and the required level of expertise for their operation. This research aims to develop a user-friendly design tool for non-expert designers that can work with appropriate solution spaces. In this way, this research presents a new evolutionary computational design tool, Ho-Gen (House Generator), which assists in the design exploration of single-family house layouts through an interactive work process. Ho-Gen is capable to generate multi-floor SFH layouts with geometric and topological criteria. Ho-Gen’s interactive interface allows the designer to guide the generation process within the intermediate states to make changes in the problem definition together with the possibility to modify generated solutions. Ho-Gen is tested with two conceptual SFH layout problems with a varying number of layout elements in an increasing level of complexity. The results show that Ho-Gen can generate a variety of valid layouts for the conceptual stage in architecture.


A generative typology for critical regionalism: An urban design perspective
Kar, Zeynep Elif; Çalışkan, Olgu; Urban Design in City and Regional Planning Department (2021-7-09)
Traditional cities have evolved through a series of local codes from material use and architecture of the buildings to the syntactic structure of settlement pattern. The building rules embedded within the multi-layered nature of the traditional urbanism characterizes traditional towns in specific manners. Various combination of the rule sets in specific manners, therefore, is the main factor in the characterization of different urban contexts and their evolution, accordingly. In this regard, any design act ...
An immersive performative architectural design tool with daylighting simulations: a building information modeling-based approach
Akin, Sahin; Ergun, Oguzcan; Sürer, Elif; Gürsel Dino, İpek (Emerald, 2020-11-01)
Purpose In performative architectural design, daylighting is a crucial design consideration; however, the evaluation of daylighting in the design process can be challenging. Immersive environments (IEs) can create a dynamic, multi-sensory, first-person view in computer-generated environments, and can improve designers' visual perception and awareness during performative design processes. This research addresses the need for interactive and integrated design tools for IEs toward better-performing architectur...
An investigation into building occupant behavior of different household typologies in architecture
Erol Ağırsoy, Meliha İpek; Gürsel Dino, İpek; Department of Architecture (2022-2)
Humans who directly interact with the built environment are a significant parameter of the architectural design process. The uncertainty in occupant behavior is a variable parameter of sustainability in architecture. Human building interaction affects energy consumption and creates an unpredicted result for the building's calculated energy use. The interaction between the occupant and the building is significant for establishing new areas of architectural inquiry. The study aims to observe the influence of ...
Rethinking the urban block in Turkey: A study with reference to siedlung typologies and perimeter housing
Özyol, Betül Gül; Balamir, Aydan; Cengizkan, Ali; Department of Architecture (2002)
Urban residential environments in Turkey from 1965 onwards are formed through the application of the detached apartment block In satellite towns, the point block dominates the housing environment. The prospect this type provides in formation of the public realm, variety of plan layouts for diverse occupants, is of vital importance and an issue of inquiry. This study aims at re-thinking the apartment block in Turkey, [its transformation from Kiraevi to the anonymous block, through the examples of two cases f...
Research by design in architectural design education
Yüncü, Onur; Aközer, Emel; Department of Architecture (2008)
Research by design refers to the design of architectural research as an integral part of architectural design processes. In 1980s, it emerged as a third way in design research that was dominated until then by the methods of natural sciences and humanities. With this new formulation of design research, a methodological and epistemological transformation occurs, leading to the integration of practical knowledge into architectural research. The primary epistemological question transforms from knowing what desi...
