title PARAMETREE: An Algorithmic-Parametric Tool for Evaluating the Contribution of the Trees on Rainwater Management
source Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1447–1461
summary This paper explores the application of an algorithmic-parametric tool that uses urban forestry as a design strategy to reduce the occurrence of flooding. The study was carried out following three main stages: (1) a literature review on the capacity of rainwater retention in tree species with dense canopies; (2) the creation of an algorithmic-parametric tool using C# scripting in Grasshopper to calculate the influence of the trees in reducing the runoff coefficient; and (3) a simulation using Rhinoceros and Grasshopper to verify the performance of such tool. The results show a new method of calculation to estimate the runoff formation in urbanized areas as well as it confirms the contribution of the trees in mitigating flooding.

summary Hospitalization is, for the patient, a neuropsychophysiological stressor, thus pertinent theories point to architectural stimuli as a tool for the homeostasis restoration and consequent well-being. Furthermore, they compile advantages to the patients’ treatment and highlight, mainly, the natural environments benefits, which is elucidated by the Biophilia theory. Through literature review and analysis of applied research in national and international hospitals, extracted from indexing databases of scientific production in the 2000-2020 timeframe, it was found that these areas [a] promote stimuli that enhance emotions and positive feelings; [b] act to restore stress and anxiety; [c] reduce pain, analgesic intake and length of stay; and [d] increase patient satisfaction. By sharing the results of this research, the objective is, in addition to stimulating future research on the organism behavior in the environments, to indicate perspectives for hospital ambiences.

summary Research in the field of additive manufacturing with concrete has gained enormous momentum in recent years. In practice, the first fully functional and habitable buildings have been realized. While these lighthouse projects have proven the general feasibility of 3D printing in construction, in the future it will be a matter of further expanding the potential of 3D printing, addressing important topics such as functional integration (reinforcement, piping, fasteners), material gradation (load-bearing, insulating) as well as disassembly and reuse.

As part of an international competition organized by LafargeHolcim Ltd. and its partners Witteveen & Bos, COBOD and Fondation des Ponts wich focused on realigning a traditionally manufactured residential building to concrete 3D printing technology, a team of students and researchers have developed a concept for a modular, function-integrated panel system for individualized wall and ceiling elements. The system is characterized by the fact that the integrated modular structures are printed flat on the floor and precise connections and structural joints are subtracted while the concrete is still in its green state.

summary This study selects four urban roughness parameters of building density, FAR, building dispersion ratio, and green rate to study the wet and cold microclimate in the winter night. According to the combination of 7 points measurement and 36 grids ENVI-met simulation, this study obtains microclimate research data. The significants of the winter night wet and cold microclimate is focused on improving the somatosensory temperature, and this study splits the target into two related directions, one is to extend the duration of comfortable temperature and humidity, another is to expand the comfortable area of temperature and humidity. By coupling analysis of urban roughness and the comfortable ratio, this study found out 11 relationship lines between urban roughness and nighttime microclimate in NanPing village. These laws offer the design strategy for NanPing Villages future development from three directions. These also provide a solution to achieve a low carbon, sustainable built environment.

summary Current approaches to smart cities have focused on implementing technologies to harvest and analyse data through sensors and artificial intelligence to improve urban performance from the top-down. However, cities are complex systems of interconnected layers that change at different speeds. More persistent layers, like networks and occupation, must have smartness embedded in them through smarter design processes. In recent years, there has been an increase in digital tools for urban design, applying computational design methods and data analytics strategies, enabling collaborative and evidence-based approaches that support sustainable urban design. A critical evaluation of their potential to inform design is necessary to aid practitioners to choose and adopt these novel strategies and tools in practice. This paper presents a critical review of selected data-driven design cloud platforms, focusing on data-driven urban design approaches that can enable the use of ICTs to steer cities into a smarter future from the bottom-up.

summary The sand table is a tool of expression of urban planning.With the development of computer science and technology,virtual reality technology is playing an important role in many aspects of urban planning and design,as well as,the virtual sand table.This article analyzes the limitations of the current urban planning sand table from designers and other participants perspectives. It analyses the advantages of applying interactive technology in a sand table for urban planning and proposes using such interactive technology in the future. This paper will also investigate three aspects of interactions: human-computer interaction technology, collaborative interaction technology, remote visual interaction technology. The application of interactive technology on the virtual sand table, on the one hand, can carry out a multi-angle forward-looking analysis of the problems of urban construction and improve the efficiency of planning and approval, and development; on the other hand, it can increase public participation in urban planning and design.

summary In continuation of our previous research (Hussein, et al., 2017), this paper examines the kinetic transformable spatial-bar structures that can alter their forms from any free-form geometry to another, which can be named as Free-form transformable structures (FFTS). Since 1994, some precedents have been proposed FFTS for many applications such as controlling solar gain, providing interactive kinetic forms, and control the users' movement within architectural/urban spaces. This research includes a comparative analysis and a critical review of eight FFTS precedents, which revealed some design and technical considerations, issues, and design and evaluation challenges due to the FFTS ability to deliver infinite unpredictable form variations. Additionally, this research presents our novel algorithmic framework to design and evaluate the infinite form variations of FFTS and an actuated prototype that achieved the required movement. The findings of this study revealed some significant design and technical challenges and limitations that require further research work.

summary As Chinese cities entering a so-called organic renewal era, building projects runs with much more constraints from high-density and high-rise surroundings. Such a situation makes the technical review in any urban planning bureau time-consuming and error-prone, which conflicts with the developers profits and citizens rights. This study introduces a preliminary system being developed for the planning bureau of Huangpu District, Shanghai. It has covered 21 code items among 44 computational ones of the local planning codes last year, which automatically generates technical reviews upon developers submissions. Due to the feasible level of BIM application in domestic projects, a set of strategic approaches, such as the standardization of CAD drawings and the reconstruction of an internal building information model, are adopted rather than developing the system on any BIM platform directly. Two examples of technical reviews about distance-checking between buildings and length-checking of facades are demonstrated, in which officers reached confidential judgments in seconds rather than several days conventionally.

summary This study was conducted to test the effectiveness of a virtual filter that digitally compensates for age-related changes in color perception. Many elderly people experience declining color perception. Medical studies have been conducted on how elderly peoples lenses affect their color perception. However, digital practical method for improving elderly peoples color perception need to be developed. Subway map is a good example of many elders daily experience. To adapt virtual filters to subway maps colors, standard short-wavelength colors, namely purple and green, were selected for variance independence (VI) because colors with short wavelengths of 400-600 nm on visible light are difficult for elderly people to perceive. Standard color VIs of subway lines and VI transferred to artificial lenses were measured with a spectrophotometer. CIE LAB and RGB; Color value on virtual filter (VD) was analyzed from VI. This virtual filter was developed based on artificial lenses using Dynamo. A visual programming algorithm was developed to adjust the color of a virtual filter through an interface. The results showed that virtual filters can be used to help elderly people detect short-wavelength colors. Therefore, virtual filters should be incorporated into lenses for use by the elderly.

title Using ENVI-met to Simulate the Climatic Behavior of Green Elements in Urban Spaces

summary The urban environment is nothing but the product of the permanent interaction between the physical elements that make up the urban space and the corresponding climatic factors. This relationship is similar to a chemical reaction, hence the difficulty of anticipating and dealing with such complex relationships. As a result, designers resort to the use of simulation software. Designers in the area of urban design must be fully aware of the ways to use these programs optimally and check the impact of the use of green elements within urban spaces in advance during the design process before practical implementation. This paper aims to integrate the design of urban spaces with the simulation of climatic behavior using ENVI-met climatic simulation software. It also aims to determine the impact of using the optimal ratio of green elements in urban spaces on the thermal comfort of their users (using two example urban spaces at the American University in New Cairo and Princess Noura University in Riyadh).

title Leaf Coverage Quantification for the Design of Vegetated Shading Geometries Using Algorithmic Modeling, Coupled with Imaging Software

summary One of the most significant parameters for obtaining positive benefits from vegetation is the leaf area index. This parameter influences the shading of the plant, acting as a solar control device in the architecture. In this sense, this work aims to collect average parameters of the percentage of leaf cover of climbing species, in a high tropical climate, through digital mapping and pixel counting, using the image software ImageJ for digital image processing and analysis. With these parameters, it will be possible to simulate the shading of the vines and predict their growth. This simulation can help designers make decisions such as mesh configurations, planting spacing, and regular maintenance. The research hopes to fill a gap in the literature on specific data on leaf cover of climbing species, which can serve as an input to the algorithmic modeling of green facades in architecture.

title A Chained Machine Learning Approach to Motivate Retro-Cladding of Residential Buildings

summary This paper investigates how a novel approach to visualisation could help address the challenge of motivating residential retrofitting. Emerging retrofitting research and practice emphasises retro-cladding - the upgrading of the exterior facade of a building - using a modular approach. We present a machine-learning based approach aimed to motivate residential retrofitting through the generation of images and cost/benefit information describing climatically specific additions of external insulation and green roof panels to the façade of a Danish type house. Our approach chains a series of different models together, and implements a method for the controlled navigation of the principle generative styleGAN model. The approach is at a prototypical stage that implements a full workflow but does not include numerical evaluation of model predictions. Our paper details our processes and considerations for the generation of new datasets, the specification and chaining of models, and the linking of climatic data to travel through the latent space of a styleGAN model to visualise and provide a simple cost benefit report for retro-cladding specific to the local climates of five different Danish cities.

summary Parametric Sustainable design of the indoor environment of double green façades buildings focus on the development of office building structure in Egypt and achieved indoor thermal comfort at a low level of energy use. The goal of this paper is to study parametric design from a wide perspective in order to classify its advantages and evaluate its skill to support Sustainable design. As building construction sector is the largest energy consumer, Operation hours of air conditioners is speedily increasing in the office buildings area through summer season, which already accounts for 50% of energy consumption in Egypt. This study was carried out based on the simulation in Design Builder (6) software. The case, studied in the article is for office building, newly erected building with surface area of 25, 500 m2 is considered as the basis for the parametric Sustainable study. The new energy model was simulated resulting in about 70% in HVAC consumption and approximately 75% for whole building energy consumption. Analysis results showed that parametric optimization of building envelope at the design stage is a practicable approach to reducing energy consumption in office building design.

summary The developments of digital technology applied to architecture in the recent decades has allowed for direct communication from the studio to fabrication. However, this process is typically dependent on complicated computational processes, enlarging the distance from the benefits of the traditional drawing approaches employed by architects. This research intends to explore possibilities of reenacting the drawing as a means of computational generative design which feeds automated systems of construction. By using a Cobot directed by an algorithm which reads a simple drawn curve on paper, an automated brick wall is built, as demonstrated in two exhibitions. This mixed approach allows for technology in architectural design and construction to be more accessible to a wider audience, while blurring the boundaries between concept and materialization.

summary This paper explores the development of Augmented Spaces that involve embedding within the built environment, digitally responsive recognition of human presence. Contemporary digital media provides the opportunity to enhance physical space with the property of immediate interaction, which results in a high level of user engagement and responsivenenss. Through the addition of digital media, emotional and reflective value can be added to the built form. If space is designed to be reactive, rather than passive, a dialogue can be established between the user/inhabitant and the environment. We report on the establishment and analysis of a set of prototype digital interventions in urban space that react to human presence. One is in a building threshold space; one an urban street. We describe the development of a digital particle system with two inputs; the first being the geometry that generates the particles and the second being the geometry that displaces the particles. The research goals that we report on are driven by three over-riding response criteria, Visceral, Behavioural and Reflective.

summary The material qualities of ceramic roof tiles have provided new formal interpretations that induced a new functional use—a wall. By disassembling ceramic roof tiles from roofs and assembling them into walls, its circularity potential was enlarged. This paper explores the potential use of ceramic roof tiles, as a single element type, in the definition of wall design systems and patterns of composition that comply with design for manufacture, assembly and disassembly (DfMA-D) requirements, through the development of a shape grammar and implementation through parametric models. The new shape grammar extends the compositional patterns already produced and the redefinition of the connection systems by incorporating DfMA-D requirements into the shape grammar rules sets new combinatorial patterns aligned with European Union goals for building circularity. The parametric models automate the generation of design solutions and extend the design process to the assembly and disassembly stages using robotic fabrication techniques.

source Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)

summary . In practical robotic construction work, such as laying bricks and painting walls, obstructing objects are encountered and motion planning needs to be done to prevent collisions. This paper first introduces the background and results of existing work on motion planning and describes two of the most mainstream methods, the potential field method, and the sampling-based method. How to use the probabilistic route approach for motion planning on a 6-axis robot is presented. An example of a real bricklaying job is presented to show how to obtain point clouds and increase the speed of computation by customizing collision and ignore calculations. Several methods of smoothing paths are presented and the paths are re-detected to ensure the validity of the paths. Finally, the flow of the whole work is presented and some possible directions for future work are suggested. The significance of this paper is to confirm that a relatively fast motion planning can be achieved by an improved algorithmic process in grasshopper.

summary Short Stack is a bare minimal structure using only laminated sheets of structural metal decking for all elements of its structure and enclosure. The project operates under a simple principle. Structural metal decking is a one-way system that resists loads well in one direction, but not in the other. When this decking is stacked into rotated sections and tensioned together, the resultant sandwich of corrugated metal is resistant to loading in every direction. These sandwiches become walls, floors, and roofs to a temporary structure. The compounded effect at the edges of the rotated and cropped decking is one of filigree or an ornamental articulation. The sandwich, which is mostly hollow due to the section of the decking, provides a sense of airy lightness that is at odds with its bulky mass. The structure, therefore, teeters between being unexpectedly open and at once heavy. The economy of the project is in its uniformity and persistent singularity. By maintaining a single palette of material and using a plasma cutting CNC bed to cut each section of the decking, the structure is simply assembled. The digital intelligence that lies underneath the apparent formal simplicity of the project is two-fold. Firstly, each sheet of metal decking is different from the next. Because of the locations of bolt-holes and constant variability of rotation and cropping of each sheet, it is a project that expresses uniformity rather than articulation through discretization. Secondly, the project appears solid and monolithic but is hollowed structurally to minimize the weight of the assembly. Parametric tools are implemented to maximize material efficiencies by hollowing the interior of each sandwich for load optimization. The project is presently in prototyping and documentation and will go into construction in Spring 2021 on a site in downtown Denver.
