In the climate change era, the tendency to utilize computer-aided strategies in architectural design enables the incorporation of the influences of ambient conditions into the design process. Such a design strategy can consequently contribute to creating nature-based, sustainable architectural, and urban solutions. In this paper, it will be shown that the built environment can be designed, already from the first concepts, to affect and consequentially improve the local wind microclimate by addressing the unfavorable wind effects and proposing solutions for transforming them into an advantage. Utilizing the iterative Research Through Design (RTD) approach, the proposed data-driven wind-oriented shape optimization is introduced in a case study located in Stockholm. Three complex architectural shapes, resulting from the wind-oriented design approach, are parametrically designed in Grasshopper for Rhino and subsequently analyzed in a Computational Fluid Dynamics (CFD) plug-in Swift for Grasshopper.

The focus of this paper is that we want to give a brief introduction about the idea of Parametric Design (PD) and the use of data to inform the design process. The digital fabrication is not covered in detail in this document. In the case study “Live Building” explains a sensory process. The project shows how to collect data, transformed and transported into a shape. Innovation is not only the approach of the draft, but the systematic procedure and the resulting diversity of solutions. The search for the geometric shape and the key to the concept will be answered in detail.

Parametric design is a paradigm for the more effective use of computers in architectural design and practice. Rather than focus on design as a holistic process of formal synthesis, the more localised issue of design development will be discussed, especially with regard to the resolution of complex geometry. The triforium of Gaudí's Sagrada Familia is taken as a case study. Parametric variation is used to define surface geometry consistent with the surviving fragments of plaster models, and what we know of Gaudí's technique.

Abstract:. Recent trends and rapid developments in computing gives tremendous impact in many disciplines beside computer science. Architecture is one of disciplines that have undergone an evolution in paradigm as a result of this development. Parametric design is one of the approaches used in architectural design which lead to the advance circumtances in design process. This approach adopts some of designer-friendly programming language where architects can utilize unlimited computation abilities from computers in search of design solutions by designing their parametric definitions or rules. This article will discuss about the parametric approach to the design of multi-storey building buildings. The case study in this research is the design competition of ASEAN Secretariat building (ESAC) organized by Ikatan Arsitek Indonesia (IAI) Jakarta. The Grasshopper platform is used to explore for building form (form-finding) that maximize the view toward its site. A simple radiation analysis is also conducted in this design process using the plug-in called Ladybug + Honey bee and Multi-Objecive Optimization using Octopus plug-in, to look for minimal radiation that is affected by the location of the building form. Keywords: Parametrik desain, Grasshopper, Ladybug + Honey bee, Octopus Abstrak: Tren dan perkembangan yang pesat dalam komputasi banyak mempengaruhi disiplin lain diluar ilmu komputer. Arsitektur adalah salah satu disiplin yang banyak mengalami perubahan dalam paradigma pemikirannya akibat dari perkembangan ini. Parametrik desain merupakan salah satu pendekatan yang digunakan dalam desain arsitektur. Pendekatan ini mengadopsi bahasa pemrograman dimana arsitek dapat memanfaatkan kemampuan menghitung yang tidak terbatas dari komputer dalam mencari solusi desain dengan merancang definisi parametriknya. Artikel ini akan membahas mengenai pendekatan parametrik pada desain bangunan gedung berlantai banyak. Studi kasus pada penelitian ini adalah sayembara desain gedung sekretariat ASEAN Jakarta yang diselenggarakan Ikatan Arsitek Indonesia (IAI) Jakarta. Platform Grasshopper digunakan untuk mencari gubahan masa yang dapat memaksimalkan view dan bentuk terhadap tapaknya. Analisa radiasi sederhana juga dilakukan pada proses ini dengan menggunakan plug-in Ladybug + Honey bee dan Multi-Objecive Optimization dengan menggunakan plugin Octopus, untuk mencari radiasi minimal yang dipengaruhi oleh bentuk dan letak bangunan yang didesain.

Construction of new design scheme in new countryside settlements should be closely around the "people-oriented and environment-centric" design concept under eco concept, with it building a sustainable village living environment system. This paper through a large number of field research and scientific research, uesd rural settlements in Guanzhong area as case study, under eco-design strategy to construct design mode of settlements planning and architectural design. And used the typical village - “Donghan”village as an example in keeping with the practice of the mode. It would have certain theoretical and practical guiding significance for the sustainable development of ruralcountryside settlements.

Target Performance

In this paper, we present a performance-based approach to building configuration design to improve the urban ventilation potential at the conceptual design stage, and we demonstrate its application through a case study. The target performance optimized was the ventilation potential of a district, including a region of interest at a spatial scale of hundreds of meters. To estimate this performance, we used computational fluid dynamics (CFD), coupled with an evolutionary algorithm, to optimize the design alternatives to produce the building configuration most suitable for a given set of site conditions. Three calculation components must be assembled for a CFD-based design optimization: an optimizer, a geometry/mesh generator, and a CFD solver. To provide links between the calculation components, we utilized an in-house parametric design program. A case study was conducted to test the applicability of the proposed design method to identify the optimal solutions that minimize adverse effects on the ventilation potential of the surrounding area. For a configuration of buildings in a dense urban area, the proposed design method successfully improved the design alternatives. The results show that the urban ventilation potential in the case of the optimized building configuration is 16% greater than that of the initial building configuration.

This paper aims at discussing the potentials of bottom-up design practices in relation to the latest developments in Information and Communication Technologies (ICT) by making an in-depth review of inaugural cases. The first part of the study involves a literature study and the elaboration of basic strategies from the case study. The second part reframes the existing ICT tools and strategies and elaborates on their potentials to support the modes of participation performed in these cases. As a result, by distilling the created knowledge, the study reveals the potentials of novel modes of ICT-enabled design participation which exploit a set of collective action tools to support sustainable ways of self-organization and bottom-up design. The final part explains the relevance of these with solid examples and presents a hypothetical case for future implementation. The paper concludes with a brief reflection on the implications of the findings for the future of architectural design education.

A computational fluid dynamics (CFD) model of a 600 MW opposed swirling coal-fired utility boiler has been established. The chemical percolation devolatilization (CPD) model, instead of an empirical method, has been adapted to predict the nitrogen release during the devolatilization. The current CFD model has been validated by comparing the simulated results with the experimental data obtained from the boiler for case study. The validated CFD model is then applied to study the effects of ratio of over fire air (OFA) on the combustion and nitrogen oxides (NOx) emission characteristics. It is found that, with increasing the ratio of OFA, the carbon content in fly ash increases linearly, and the NOx emission reduces largely. The OFA ratio of 30% is optimal for both high burnout of pulverized coal and low NOx emission. The present study provides helpful information for understanding and optimizing the combustion of the studied boiler
