Rethinking Ephemeral Architecture. Advanced Geometry for Citizen-Managed Spaces

Abstract

In recent years there have been a high amount of citizen initiatives that address the complex problems of the contemporary city. There are empty or disused spaces that have been reused for urban gardens, for social use, to encourage integration and civic activities activation, etc. Traditional architectural processes do not provide realistic solutions to these initiatives that, along with limited financial resources, have led to the emergence of architectures and self-constructed facilities, almost as an emergency mode, without necessary planning, media and constructive knowledge. The democratization of technology, thanks to laboratories of digital production, combined with knowledge of the properties of different surfaces through the CAD-CAM tools, offers new opportunities for the development of a lightweight, flexible and low impact architecture, very according to the needs of citizens' initiatives that naturally arise in our cities. The new existing scenario contemplates the figure of the architect, or engineer, not only as an agent of the market, but as a professional able to propose efficient solutions to problems from within, bringing their specific knowledge and serving as bridges between the new technological solutions and the challenges of society.

Architectural Graphics Research: Topics and Trends through Cluster and Map Network Analyses

“…Regarding topics, the predominance of an architecture research field concerning its artistic nature has been confirmed, in which the most repeated concepts are art, form, idea or drawing. Meanwhile, digital manufacturing is one of the graphic analysis research fields that architects are not exploring and that could be used to manufacture high-detail models [49], to produce ephemeral elements [52] or to develop mechanical prototypes.…”

“…The third field incorporates the topics of design and manufacturing (see Table 3). Research is related to the process and the possibilities of modeling through CAD software, and its subsequent materialization through digital manufacturing [47], the design of methods for the automatic analysis of the parts that will be physically obtained after modeling to improve performance for subsequent uses [48], the preservation of aerospace heritage through low-cost manufacturing techniques for high-precision models [49] (see Figure 3), 3D scanning for the production of elements, such as prostheses [50], or food to design its packaging [51], and even the generation of ephemeral architecture [52].

Energy Benefits of Tourist Accommodation Using Geodesic Domes

“…The speed of the execution of their structure allows for the transport and construction of resistant shelters, even those with military applications. Moreover, no in-depth studies of spherical trigonometry or stereographic projections [49] are required for their design or construction. This is why, in recent years, their use as accommodation has proliferated so much.…”

Digital Fabrication and Mass Customization in temporary structures: a systematic review of literature

“…Em dois artigos as pesquisas foram desenvolvidas usando um conector de peças estruturais para estruturas de forma não-estândar (Crolla et al 2019;Adrita;Widyowijatnoko, 2016); um trabalho apresentou um modelo computacional para CM de estruturas em madeira (Mork et al, 2019); em duas pesquisas foram desenvolvidos o objeto arquitetônico a partir de superfícies planas (Martín-Pastor et al 2017a;2017b); um trabalho trouxe um modelo que utilizou elementos construtivos padrão para desenvolver uma estrutura não estândar (Schimek;Stavric;Wiltsche 2013).…”
