summary The focus on efficiency has grown over recent years, and nowadays it is critical that buildings have a good performance regarding different criteria. This need prompts the usage of algorithmic approaches, analysis tools, and optimization algorithms, to find the best performing variation of a design. There are many optimization algorithms and not all of them are adequate for a specific problem. However, Genetic Algorithms are frequently the first and only option, despite being considered last resort algorithms in the mathematical field. This paper discusses methods for structural optimization and applies them on a structural problem. Our tests show that Genetic Algorithms perform poorly, while other algorithms achieve better results. However, they also show that no algorithm is consistently better than the others, which suggests that for structural optimization, several algorithms should be used, instead of simply using Genetic Algorithms.

title Towards an Interactionist Model of Cognizant Architecture - A sentient maze built with swarm intelligence
source Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 2, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 201-208

summary Cognizant Architecture is a term used to define sentient and smart structures broadly. In this paper, an 'Interactionist' model of cognizant architecture is proposed as a method of investigating the development process by inverting the conventional concept of maze design. The proposed 'Cognizant Maze' aims to achieve user-architecture micro-interactions through delighting the users, presenting a physical activity equally attractive to kids and adults alike, and activating mind-enticing visual effects. Like many previous innovations, nature is what inspires us in the maze-making process. In modelling the cognizant maze, we develop the concept and workflow of prototyping a form of swarm intelligence. We are particularly interested in exploring how simulated behaviours of swarm intelligence can be manifested in a maze environment for micro-interactions to take place. Combining parametric modelling and Arduino-based physical computing, our current interactive prototyping shows how the maze and its users can 'think, act and play' with each other, hence achieving an interactionist model of cognizant architecture. We reflect that the lessons learned from the Cognizant Maze experiment may lead to further development of cognizant architecture as a propagation of swarm intelligence through multi-layered micro-interactions.

summary This paper explores the impacts of the Internet of Things (IoT) on the field of interactive architecture and the ways this novel technology enables realignments toward inclusive and critical practices in the design of computational systems across different scales. Specifically, it examines how the integration of IoT in the design of architectural surfaces can encourage interaction between local and remote users and increase accessibility amongst contributors. Beginning with a survey of media facades and the superimposition of architectural surfaces with projected images, the paper outlines a historical relationship between buildings and the public realm through advancements in technology.

The paper next reveals ways in which IoT can transform the field of interactive architecture through the documentation and analysis of a project that stages an encounter between local and remote Wikipedia contributors. The installation creates a feedback loop for engaging Wikipedia in real-time, allowing visitors to follow and produce content from their interactions with the gallery’s physical environment. Light, sound, and fabric contextualize the direction and volume of real-time user-generated event data in relation to the gallery’s location, creating an interface that allows participants to dance with dynamic bodies of knowledge.

By incorporating IoT with the field of interactive architecture, this project creates a framework for designing computational systems responsive to multiple scales and expanding our understanding of computational publics.

title Incorporating Form Diversity into Architectural Design Optimization
source ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 640- 649
doi https://doi.org/10.52842/conf.acadia.2017.640
summary In this study, we introduce a new approach that incorporates form diversity into architectural design optimization, which will potentially accommodate designers' aesthetic judgment into the whole building optimization process. Form diversity is defined here as the level of difference in building geometric forms. We developed a form comparison algorithm to lead to a reasonable number of optimal design solutions of highly diverse forms. This allows for a post-optimization articulation of preferred solutions, and helps satisfy the aesthetic criterion in parallel to the measurable objectives. The methodology involves experimenting and prototyping. Experiments were done at different progress levels of the optimization tasks to test the feasibility of the system’s framework. A prototype framework was developed using parametric modeling, energy simulation, daylight simulation, Pareto optimization, and Multi-Objective Genetic Algorithms. The initial results demonstrate that the system has the capability to successfully work as desired with possible improvements. Comparison of results before and after shape comparison is discussed.

summary Mangalabas (Goodwill House) is a historic multi-court mansion in Farashganj, Old Dhaka, Bangladesh. The spatial layout combines multiple courtyards, demonstrating how the courtyard is an integral part of traditional Bengali houses and vernacular buildings. During the British colonial period, Mangalabas and many other multi-court mansions were built in Dhaka by combining the native spatial organization of courtyard buildings with imported European elements (Rahmam and Haque, 2001). This typology is unique to Bangladesh and offers configurations with spatial, social, and environmental values that are often missing from contemporary housing in Dhaka. This paper revisits the vernacular essence of Bengali courtyard-based living and presents a 3D voxel-based interpretation of Mangalabas to promote the potential of this building form. The research focuses on inferring shape rules of the volumetric composition to understand the programmatic relations between the courtyards and overall massing. Voxels are used to represent these relationships in a straightforward way and to strategize for the computer implementation of grammar in future work. The current study sets a foundation for understanding this Bengali housing type and the logic of its building form as a basis for designing new housing prototypes that learn from this vernacular.

title Robotic Plaster Carving: Formalizing subtractive detailing of plaster surfaces for construction and crafts

summary Plaster has been a fundamental material in numerous interior and exterior applications in architectural construction due to its fire-resistant properties and capabilities for intricate detailing. Moreover, prior to the widespread adoption of computer-aided design tools, plaster played a crucial role in historic preservation and architectural education (Mankouche & Schulte, 2012). While the use of decorative plaster elements in architectural construction has waned in popularity, the renewed interest in plaster within the context of advanced robotic fabrication offers a compelling basis for research. This paper presents an investigation into robotic plaster carving for adding detail and texture to plaster surfaces. Within the scope of this study, we identify and systematically examine various fabrication and material parameters for emergent geometries and fabrication defects, subsequently formalizing this robotic workflow for diverse applications in construction and crafts. Among these parameters, we primarily concentrate on toolpath geometry, tool orientation, carving speed, carving profile, and aggregation of carving strokes. Through this bottom-up approach, our objective is to enhance the understanding of tool-material interaction during the fabrication process and achieve improved control over the resulting artifact. Building on these insights, we demonstrate how the proposed robotic plaster carving workflow can be employed for subtractive surface detailing in architectural construction and digital crafts.

doi https://doi.org/10.52842/conf.caadria.2019.1.815
summary This paper discusses the characteristics of and relationships between the most common building energy performance tools for simulating and visualising the thermal behaviour of buildings at the early stage of building design. The necessity for the latter and the importance of using relevant tools in practice are discussed. By highlighting existing gaps in these tools, a complementary component has been suggested that could assist building scientists in evaluating energy simulation results. The proposed energy performance data visualisation (EPDV) component is an under-development plugin (SlowLoris) that is intended to be added to the existing Grasshopper add-ons. This EPDV component provides users with simultaneous but different visualisation styles of monthly energy reports for individual floors and thermal zones. As an example, this paper uses a 2-storey building model to show the applicability of the plugin to analysis of energy simulation results.

title Bamboo Concrete Shells - An Adaptable Construction Method Using Onsite Materials in a Remote Location

doi https://doi.org/10.52842/conf.caadria.2017.445
summary This paper proposes an on site construction support system using digital techniques to solve the issue of logistical inconvenience on remote islands, where industrialized construction methods are absent. Transporting heavy machinery is costly and difficult in isolated rural areas. In addition, introducing materials from outside creates a heavy ecological footprint when building. Locally produced construction materials resolve many of these issues. To test the potential of building within these constraints a case study site on an isolated island of Japan, named Kuchinoerabu, was chosen. A concrete shell structure was created using locally sourced bamboo as reinforcement. Through the study, several technical issues are revealed. Significantly, there is broad variation in the material properties of bamboo, and reducing errors when using unskilled labor is difficult. The system nominally manages the following functions: 1) Synchronizing data between CAD and the materialized form; 2) Checking errors between the target form and the one that was actually produced; 3) Inputting material characteristics on site. 4) Making a structural analysis, and reflecting its execution during construction. These functions minimize the margin of error, and aid an unskilled labor force to work more accurately.

title Adaptable Design-Construction Method for Remote-Location - Experiment with Reverse-Engineering System to Expand the Possibilities of Natural Materials with Bamboo Concrete Shell as a Case Study

summary In this paper, the aim is to develop a construction system that utilizes digital technology which measures the completed shape and checks its degree of safety. This is because in the case of conventional construction, it is assumed that drawing and structure are consistent by using advanced construction techniques. However, it cannot always be assumed that there are correct composition parts and advanced construction techniques in all geographical areas. Under such conditions, and through the use of digital technology, it can be easier to integrate the errors that occurred while the structure is being built as part of the construction process rather than to try to make the structure consistent with the original design.

summary From the beginning of digital revolution, structural surfaces drew significant attention as a realm that interweaves formal explorations, form-finding and structural optimization. However, after successful experimentation in the virtual domain, it became evident that some of the main challenges lay on how to translate these structural forms into architectural assemblies at the scale of buildings. The development of digital fabrication is crucial in this task, as means to overcome traditional constraints such as need for modular pieces, scaffolding and optimal assembly sequences.This research focuses on digital workflows that combine form finding with robotic fabrication, surface tessellation and panelization. In the past years, the use of digital tools to assemble identical modules into complex formations has achieved significant results for loadbearing walls. Expanding this line of research, the proposed fabrication system carries these experiments on additive fabrication into the production of structural surfaces. The assembly sequence involves a two-step fabrication: off-site panel manufacturing and on-site assembly. The main components of the system consist of two triangular ceramic pieces that provide structural resistance, refined surface finish, and formwork for thin reinforced-concrete layer. Panelization strategies reduce the requirements on-site work and formwork.The paper describes background research, concept, construction process, methodology, results and conclusions.

summary For years, lack of public participation has affected the quality of design and planning. The developing cities constantly face the anti-development sentiments on the part of local residents because of controversial decision of development. Rapid development of information technology provides us with a chance to mend the delay of communication with the public in design procedure. It makes it possible to get the resident's reaction to a new project. Unlike a purely CAD-based environment, computer application to urban design is based on a blend of computer-aided design, spatial information system, and interactive multimedia. It is the combination of geometric, geographic, and annotated information and the need of data integration by collaboration and meanwhile it provides opportunities of participation. Due to the position at the crossover of architecture, landscape architecture, and planning, urban design attempts to control the proceeding in both design improvisations and socio-economic policies. In this proceeding, public participation plays an important role in exchanging opinions with the masses. In the situation of participation in China, we can synthesize some useful methods of public participation in the urban design by means of computer simulation, computer communication, and diverse software and tools, etc.

summary "The introduction of digital tools in the production of architecture undoubtedly constitutes the main force behind contemporary architectural innovation. In addition, the interaction of digital technologies with analog craft manufacturing -a rather unexplored field of study- suggests a wide range of novel opportunities. This research focuses on developing a framework for deploying digital design techniques to the production of bricks under vernacular technology as a medium of achieving geometrical variations and functional complexity in domestic-scale projects. Solid clay bricks are embedded in traditional ceramic-construction culture. Thus, this investigation faces the challenges of making a feasible innovative system in a country where digital fabrication is not an economically viable option, and engaging a design that can be easily implemented with current hand-labour. Consequently, the new bricks would be massively introduced in the construction market, allowing novel formal and functional possibilities for designers.

summary Due to the global energy deficit, building energy consumption has become a significant issue in recent years. Many researchers have focused on building energy consumption simulations to manage energy consumption accurately and provide a comfortable indoor environment for occupants. In building energy simulations, accurate input of building parameters is essential. As important thermal parameters, the thermal transmittance (U-value) of building envelopes can affect building operational energy consumption. In most building energy simulation studies, the U-value was set to the theoretical U-value which was a fixed value. However, the U-value constantly varies due to several environmental impacts, especially fluctuating air temperature and relative humidity (T/RH). Thus, the U-values are dynamic in actual situations, and inputting dynamic U-values into building energy simulations can reduce the gap between the simulation and the actual situation. In this study, the dynamic U-values of conventional cavity envelopes in temperate zones were predicted by an artificial neural network (ANN) model. Firstly, the in-situ dynamic U-value measurement was conducted in Sheffield, the UK, from summer to winter in 2022. The heat flow meter method was applied, and the tested envelope was a conventional cavity envelope widely used in the UK. The indoor and outdoor T/RH were measured and recorded as well. Then, the measured data were applied to train the optimal ANN model. The input parameters included the indoor and outdoor T/RH, and the output parameter was the dynamic U-value. Finally, the prediction results obtained by the optimal ANN model were closely correlated with the measured dynamic U-value. This quantitative study of dynamic U-values examined the relationship between dynamic U-values of conventional cavity envelopes and environmental factors, which can provide reliable information for improving the inputting patterns of building parameters and the accuracy of the building energy simulation.

summary The key aim of this paper is to develop a computational method for mapping architectural space used for visual openness analysis. We suggest that the result will offer possibilities for quantitative design analysis particularly on spatial quality influenced by architectural elements. The proposed method consists of two stages: determination of subdivided enclosed spaces and measuring quality using visual openness parameters on each subdivided enclosed space. We advise new approach to determine subdivided enclosed spaces on architectural plan by determining two factors: bounded space and circulation space. Computational procedures applied to analyse architectural plan and then determine map of subdivided enclosed space by analysing relationship of these two factors. The concept underlying this method is that architectural space is composed of subdivided enclosed spaces, which each of them have distinct physical properties and therefore become possible to develop mapping of evaluation regarding the quality of architectural space. Our finding on orthogonal architectural plan provides ranking index of subdivided enclosed spaces that could help for analysing spatial quality of architectural space.

summary In the 70s-80s Kenneth Frampton, defined the phenomenon of "critical regionalism" in contemporary architecture. He pointed out that the most interesting objects arise at the threshold between local and global architecture. These are objects that are open to modern technology in various fields of science, and at the same time remain rooted in the local tradition of building , thus to create a space that is approved and understood locally. The article presents two examples of buildings (the Ma³opolska Garden of Arts in Krakow and the Polish Pavilion EXPO 2005 Aichi in Japan, Europe - Far East Gallery in Krakow) that look for their individual contextual sources, turn to experiments with traditional materials, try to find lost threads of handicraft tradition, and at the same time reach for modern technologies with respect for the natural and cultural environment.

summary To assess an environmental design, augmented and diminished reality (AR/DR) have a potential to build a consensus more smoothly through the landscape simulation of new design visualization of the items to be assessed, such as the green view index. However, the current system is still considered to be impractical because it does not provide complete user experience. Thus, we aim to improve the robustness of the AR/DR system and to integrate the estimation of the green view index into the AR/DR system on a game engine. Further, we achieve an improved stable tracking by eliminating the outliers of the tracking reference points using the random sample consensus (RANSAC) method and by defining the tracking reference points over an extensive area of the AR/DR display. Additionally, two modules were implemented, among which one module is used to solve the occlusion problem while the other is used to estimate the green view index. The novel integrated AR/DR system with all modules was developed on the game engine. A mock design project was developed in an outdoor environment for simulation purposes, thereby verifying the applicability of the developed system.
