Publication Diversity and Variation in China's Yao Ancient Wood Frame Structures Through Genetic Algorithms(2022) ;Afonso, Filipe ;Jedenov, Kirill ;Januario, Pedro GomesAlmeida, PauloThis study, focusing on the China's Yao minority community, investigates the feasibility to create a generative computational method to replicate the diversity of the existing Yao traditional wood buildings, addressing the critical issues currently facing computational design methods, in the attempt to adapt genetic-generative algorithms to the study of local ancient architecture. The project develops a computational tool to generate a network of three-dimensional prototypes, or building structures, derived from traditional wood frame village houses. It studies possible housing structures that illustrate some of the key working methods available in digital systems such as �generating' and �compositing' taking as a starting point computational strategies oriented towards geometry and where a set of local variables play a decisive role: available local technologies, use of raw materials, and the dimensioning of timber components based on data collected from Yao architecture. - Some of the metrics are blocked by yourconsent settings
Publication Post-disaster Temporary Housing System based on Generative Design Method(2021) ;Afonso, FilipeLu, Jun C.In the current context of frequent natural disasters in China, this paper chooses to combine computer generative design methods with post-disaster modular temporary housing as a research topic, and studies the architectural generative design method and the temporary resettlement of disaster victims from a new perspective. Architecture is being nowadays radically rethought in the design processes it employs, moving away from the traditional approach of individual 'signature' buildings or from a simply functional design, to the logics of nonlinearity, in which evolutionary intelligence plays an important role. This is a way of creating architectural structures as a result of a programmed system. In particular, the paper aims to develop and explore computer programming processes to quickly generate a modular housing combination method to provide an efficient and scientific post-disaster modular temporary housing design proposal. This research will provide new possibilities for temporary housing settlements for disaster victims in China and a new approach in computational architectural design under this context. - Some of the metrics are blocked by yourconsent settings
Publication Potential for the design of an energy saving facade system using agglomerated cork: Implications in subtropical climates(Jiaotong Liverpool University, 2019)Afonso, FilipeAgglomerated cork is a known material by its contribution to the sustainment of the environment, not only because it is a wholly natural material, without chemical additives, but also because its industrial process of production results from the lowest quality residues of cork or industrial waste material, unsuitable for other applications. It is a reusable material, this means, the cork facade elements can be converted into a new agglomerated material, demonstrating a huge potential for adaptation to existing buildings following a reversible process. It is durable, lightweight, water resistant, low-cost material, some of the properties that may qualify it as suitable for application in large surfaces of vertical construction façades. The aim of this article is to analyze the mechanical, thermal and acoustic characteristics of cork composites against site-specific climatic conditions of subtropical climates and its suitability as an external coating system for residential buildings with the goal to reduce the energy consumption for cooling the inner environment. In high-density cities like Guangzhou, Shenzhen and Hong Kong the majority of the buildings starting from the 1960s until early 21st century (Brach & Song 2006), did not integrate thermal insulation systems into external walls, producing a high level of heat transfer through the external façade from the outside environment during spring and summer seasons. Due to the extremely fast urban growth of the modern Chinese city, little importance is given to the quality of the external walls in current residential building construction. For at least during six months each year the consumption of energy due to air conditioning in Guangdong province is extremely high. The study concluded that substantial energy could be saved by implementing an external coating upgrade to existing buildings. Additionally, this study details the result obtained through software for energy simulations (Design Builder, ENVI-met) demonstrating the potential of this project to produce homogeneous and comfortable inside temperatures, which cools the indoor ambient temperature in summer time. - Some of the metrics are blocked by yourconsent settings

Publication Study of the Compositional Rules of Design in Chaoshan Traditional House: A Computational Approach(Association for Computing Machinery, 2022)Afonso, FilipeThis study is an attempt to understand and describe the compositional principles of Chaoshan traditional houses (CTH) through a computational space syntax. In this approach, the space syntax is used to describe and verify the compositional rules of Chaoshan houses. Chaoshan rural residence is a classical Lingnan style building in Chaoshan area of eastern Guangdong province, associated with Teo-Swa people, a Han Chinese minority. This study takes the example the prototypes existing in the village of Zhupu, Haojiang District, Shantou city as a case study, to analyse the spatial form of the residences. The Zhupu village houses date from the Qing Dynasty - Qianlong period, around 1700 AD. The hypothesis of this study is that CTH buildings are a result of a space compositional rule system that can be described and replicated through a computational design methodology. This study will establish a computational architectural syntax, and is the first stage of an extended research work on the evolution of Chaoshan residential types. The understanding of this evolution may help, as future work, to develop urban strategies for adaptation of the CTH heritage buildings to the contemporary living conditions. As the result of this study is a computational 3D graphics modelling algorithm, the ability of the system to generate the house layouts is not limited to the reconstruction of existing typologies of CTH and its variations. The same algorithm will allow the generation of new housing schemes, with adaptation to design variables extracted from a particular site and region.
