Summary

The work focuses on the formal and functional value of materials for building enclosing elements. They form the skin of the building, giving it an identity and recognizability in which the designer leaves his mark. Closing elements also serve the important function of a filter with the external environment. In recent years, the construction of double facades with metal load-bearing structures and closure panels made of various materials has become widely used as a passive energy-saving systems system. In the perspective of new models of circular economy to which the construction sector will also have to adapt, the work proposes a critical reinterpretation and a rediscovery of tectonics architecture. Tectonics indeed deals with the understanding of the syntax of building components with their dual formal and functional value, eschewing the fashions of the moment based on the search for increasingly surprising formal solutions. The recognition of the essential link between the form and function of the individual building component and the understanding of the role it plays in the construction are necessary conditions for making buildings sustainable. The other important aspect is the choice of sustainable materials that can no longer be produced and used according to the models of the linear economy with the use of non-renewable raw materials and energy-intensive production processes. The work presents as a case study an innovative example of the use of perforated galvanized steel sheets with automated laser cutting in the construction of the double facade of the building of the company Intertronic in the industrial zone of the park technological of Valencia. Sheet metal is the production waste of an industry located a few kilometers away from the construction site that produces metal components for industrial machinery. The building built in 2004 with a project of the Architects Carmel Gradolí and Arturo Sanz received the Prize and recognition Official College of Architects of the Community of Valencia for its innovative and sustainable design.

Summary

This paper presents the experiences cumulated in three stages of design-build experimentations through the work of graduate theses on a building that is being redesigned and retrofitted since more than a decade by volunteer work, utilizing recycled materials and re-used components with criteria of environmental sustainability and ultra-low economic cost. The lessons learned have been valuable under several viewpoints. The paper described, in particular, the works that have been built in the first two editions of the workshops, seeking the traces of an evolution within the experience, and attempting some considerations about the challenges and opportunities stemming from component reuse in participated building rehabilitation.

Summary

The tertiary sector of Italy’s building heritage is outdated, energetically inefficient, and not suitable to address the challenges of the climate crisis or the changes in post-pandemic society. Its redevelopment is one of the main strategies of the Italian government’s policies, in accordance with the European Union’s guidelines, aimed at reducing land consumption and promoting economic recovery and energy transition.

The recovery of this building stock is essential from a perspective that considers waste not as rubbish, but as a resource to reduce inequalities, social exclusion, and respond to the new needs of living and working spaces. This article aims to investigate how recladding as well as energy and seismic retrofitting of buildings, applied through a multidisciplinary and integrated design approach, can constitute a valid strategy for the recovery of this building stock. This strategy will increase energy efficiency and structural stability, and functional flexibility, while at the same time giving these buildings a new architectural identity. This paper presents a pilot project carried out by a multi-disciplinary team of Sapienza University on an office building in Rome. The experiment is described in detail, highlighting the critical aspects and the potential of the integrated design approach.

Summary

The article provides an overall picture of architectures which, in terms of construction technologies and systems as well as materials and application techniques, have been identified during global events generally with a multi-year frequency of sporting interest such as, among the most media-relevant, the Olympic Games - winter or summer - the World Cup or the Continental Football Championship, and of international socio-political involvement such as the Universal Exhibitions.

The article intends to focus on the impact of such constructions within a complex and common planning process for which, in most cases, the aim is to decommission, move, convert or reuse them in relation to the strategies and provisions defined by the competent bodies. An approach aimed at sustainability in the broadest sense of the term whose general application struggles, more and more often, to identify the right direction in respect of social, economic, technological and environmental principles and performance.

In this sense, while embracing the undoubted avant-garde power of international events, these manifest weaknesses that inevitably constantly characterize any process of this magnitude and, therefore, there is an ongoing investigation into the possibilities of developing strategies for the recovery of elements and places through techniques capable of reducing their overall impact.

Summary

In the last few years, there has been an increasing number of projects on different scales made with reused or recycled materials. These can vary from building materials or construction elements to furniture, urban equipment, or large structures.

The most striking are those signed by well-known architects or internationally renowned architecture and design studios. However, there are interesting examples of circular economy applied to construction that the inhabitants develop in an autonomous, organic, and spontaneous way. This way of building can be found in several informal settlements, where emergency conditions lead people to self-build their homes with the few materials and resources available.

Generally, in informal self-built housing, the materials used are construction and demolition waste and everyday items that are in the last phase of their life cycle. While there is no doubt that the misuse of such materials can diminish the quality and comfort of housing, the reuse is a practice that can be improved through the relationship between the community and the professionals of the building environment.

This article aims to illustrate how a virtuous circular economy could be implemented in informal contexts by combining the knowledge and skills of the inhabitants with the expertise of the professional architect.

Summary

The built environment remains the biggest consumer of natural resources globally, with construction and demolition materials among the main sources of waste in developed countries. Technolgical advances in construction methods and materials alone are not sufficient to offset the environmental impacts of design and construction processes; thus, circular design strategies should be developed and implemented to extend the lifespan of buildings, construction components and materials, keeping resources in use longer and at their highest value. Stretching this approach, this paper discusses potentials and limitations of urban mining for turning products at the end of their useful life (classified as urban waste) into a source of ‘as-new’ building products. Challenging conventional building design approaches, the paper explores alternative construction methods with low-grade materials and interrogates the potential of using urban waste in high performance building construction.

A temporary seaside facility in Liguria (Italy) is presented as an example of urban mining-based design, where type of recoverable materials, distance from the building site, and collection time become additional, and yet critical, design criteria. Environmental and social impacts of urban mining at the city scale and further research opportunities are then discussed as possible venues to increase the uptake of this alternative design approach.

Summary

Enhancing local resources, rethinking the concept of waste, promoting low environmental impact architecture, fostering industrial symbiosis and cooperation among stakeholders, designing without waste are all actions that link to the goals of the 2030 Agenda (2015) and the European Green Deal (2019), urgent objectives at the attention of international policies. In this context, the article aims to present research that experiments with a circular approach to the design by activating new synergies among local actors through the design of a Circular Park in the Monferrato hills. The park tells the story of how waste from a specific territory can become a resource for that place and, through the dimension of physical-visual experience, it encourages future generations of citizens towards new values, by transmitting circularity.

In particular, the article describes materials and methods for designing the Circular Park, that led to the development of a micro-architecture, built with disused farm tools and equipment and agricultural waste recovered from local producers.

Moreover, the article highlights the importance of challenging new ways of teaching and learning, carried out in the field, and demonstrates how even a ‘small-scale’ intervention can be a promoter of local development, with transferable results to other contexts.
