Economic sustainability scenarios for the redevelopment of sports facilities: a proposal for the “Fausto Coppi” Motovelodrome in Turin
Full text linkThe recovery of sports facilities, especially those considered particularly interesting from an historical and cultural perspective, appears today as one of the main challenges to the enhancement of the architectural heritage. In fact, alongside the issues linked to the maintenance of their formal characteristics, the conversion of these spaces into flexible, multifunctional and modern facilities is central to ensuring the economic sustainability of their management, increasingly entrusted to private investors.
This paper presents a hypothesis for the enhancement of the Fausto Coppi Motovelodrome in Turin, a famous facility which was a landmark for cycling and sports lovers in the past century. Together the enhancement of the existing structures, the design proposal provides for the addition of a new building for sports and commercial use. The methodology applied aims at evaluating the benefits of the proposal through a preliminary estimate of the construction costs and the definition of a catchment area and of a possible management scheme, with its costs and revenues. Finally, by simulating alternative scenarios, the incidence of the increase of the commercial surface on the revenues is explored. Lastly, by pointing out which possible future scenarios are plausible for the recovery of the site, the main design proposal relates to the Feasibility Study and the Call for the assignment of the Motovelodrome, published by the Municipality of Turin in February 2020
Adaptation, Mitigation, and Smart Urban Metabolism towards the Ecological Transition
Full text linkThe paper discusses the relationship between adaptation and mitigation in different dimensions (temporal, spatial, economic, political, psychological, social, and finally architectural), to highlight the existing or potential links. The perspective the one of the systemic and multi-scale design approach, capable of integrating its benefits. This strategy is based on widespread technological awareness, on smart metering, and on available IoT technologies, which can be integrated into buildings to govern the metabolism of matter and energy of the urban system. The essay relates disciplinary and specialized scientific approaches, making a synthesis focused on the theme of the relationship between global warming, ecological transition, enabling technologies, and perception of the risks associated with climate change in progress
IoT in Building Process: A Literature Review
Full text linkThe pervasive diffusion of digital technologies opened up to new concepts in managing and monitoring the processes occurring in our society. Information and Communication Technologies (ICTs) become enabling tools to rethink our way of living, consuming and producing goods and services. Among these, the Internet of Things (IoT) represents the disruptive technology that may redefine the stages of the building process to meet renewed environmental challenges. This new technological paradigm imports in the Architecture, Engineering and Construction (AEC) sector new and not-tectonic instances. In this context, the paper maps the experiences related to the use of IoT for managing the building process. Through a systematic literature review, the article highlights the potential benefits generable by a widespread integration of IoT in the AEC sector. In particular, the article has three purposes: defining the IoT infrastructure for its proper application in the AEC sector; identifying IoT main application domains; investigating the integration modalities
Smart Construction Objects.Tools for reprogramming the city
Full text linkThe focus on the concept of Smart Cities in the shift towards circular development models derives from the ability to govern increasingly complex phenomena and processes. By introducing data-driven approaches, the information produced by ICT technologies allows us to ‘reprogram’ the functioning of the urban system, as a complex ecosystem in which matter and energy are continuously transformed. Starting from the analysis of research experiences carried out at the European level, this paper aims to explore potential and real barriers related to Smart Construction Objects in urban processes. Technological-digital integration, the use of data, and the emergence of new economic management models based on services are investigated with reference to façade systems, as components able to generate and share information to govern the input and output of the urban metabolic system
Environmental sensing and simulation for healthy districts: a comparison between field measurements and CFD model
Full text linkAtmospheric Particulate Matter (PM) is considered among the main risk factors for cardiovascular, respiratory, and carcinogenic diseases. Besides, heat waves accounted for 68% of natural hazard-related deaths in Europe between 1980 and 2017 and many climate models project a global rise in climate hazards. Environ-mental Monitoring (EM) is a key resource to control health determinants, addressing threats arising from unhealthy external conditions. Forecasting models may need data coming from pervasive distributed sensor networks and computational simu-lations. Moreover, district-scale Environmental Sensing (ES) and Environmental Modelling Simulation (EMS) may identify criticalities and specific strategies to miti-gate climate risk affecting physical health. This paper compares the output from ES, by field measurements during a “climate walk” joined by more than 60 people, with EMS, by a Computational Fluid Dynamic software (CFD). The assessment has been performed on a real urban district. For on-site measurements, data were acquired by low-cost IoT-based sensors developed by the authors. For simulations, we used ENVI-met, a prognostic non-hydrostatic CFD. Potential Air Temperature and PM 10-2.5 concentration parameters have been measured and simulated on a specific winter day. Results are presented and discussed through a visualisation matrix making the comparison direct. The analysis of the results pointed out the role of ES and EMS for high-resolution scenarios assessment. Although real-time moni-toring needs extensive infrastructure at the urban scale, the use of low-cost sensors and a citizen science approach could provide precise input data to support even more accurate models, towards a healthy district site-specific design perspective. This may finally contribute to achieving the Sustainable Development Goal 11.6, aiming at reducing the adverse environmental impact of cities, thus paying particular attention to air quality
Verso uno Smart Community Welfare per una risposta al disagio abitativo. Towards a Smart Community Welfare as a response to the housing emergency
Full text linkL’implementazione di una rete abitativa sociale richiede l’adozione di politiche di welfare in un quadro normativo nazionale condiviso, nonché di modelli organizzativi, progettuali e comunitari, abilitati dalla pervasività delle ICT, tali da consentire un cambio di paradigma nella struttura dualistica del mercato immobiliare. In seguito ad un’analisi condotta su più livelli e al coinvolgimento di enti gestori di Housing Sociale, emergono linee guida programmatiche –
nell’ambito delle policy per la casa – e progettuali – nell’ambito dello spazio fisico e digitale in grado di favorire relazioni socio-assistenziali peculiari – rispetto alla promozione di un network abitativo sociale alternativo, attraverso un approccio in grado di integrare gli ambiti considerati (Smart, Community, Welfare).
The implementation of a social housing network requires the adoption of welfare policies within a shared national regulatory framework, as well as new organisational, design and community models, enabled by the pervasiveness of ICT, in order to allow a paradigm shift in the dualistic structure of the real estate market. Following an analysis conducted on several levels and the involvement of local social housing authorities, we identified guidelines that are both programmatic – in the context of policies for the home – and project-related – regarding the physical and digital space, able to foster peculiar socialcare relationships. In this perspective, the integration of the domains considered (smart, community, welfare) could promote an alternative social housing network
Introduzione. Processi circolari e settore delle costruzioni: ricerche e riflessioni / Introduction. Circular processes and the construction sector: research and considerations
No full textIl nodo dell’istituzione di processi circolari nel settore delle costruzioni è da tempo centrale nella riflessione dei ricercatori, sia per la rilevanza quantitativa dei rifiuti da C&D sia per le sue potenzialità nella prospettiva della transizione ecologica. Il ciclo di raccolta dei materiali di scarto da demolizioni, manuten-zioni e cantieri è oggi fortemente strutturato ed efficace nella prevenzione della dispersione nell’ambiente. Tuttavia, stentano ancora ad affermarsi vere e proprie filiere produttive circolari capaci di trasformare il rifiuto, come materia prima seconda, in nuovi prodotti con sostanziali riduzioni delle pressioni sull’ambiente in termini di minori fabbisogni di energia e sfruttamento di materie prime non rinnovabili. Le motivazioni sono molteplici: dalla riduzione del valore economico del materiale riciclato, alla complessità intrinseca del “sistema edificio”, alla varietà di processi tecnologici coinvolti nelle filiere produttive dei prodotti della costruzione
From CFD to GIS: a methodology to implement urban microclimate georeferenced databases
Full text linkThe objective of this paper is to present a methodology for the integration between a Computational Fluid Dynamics (CFD) microclimate simulation and a Geographic Information System (GIS). The first workflow involves the attribution of spatial coordinates to the point data extracted from the CFD, the implementation of a SQLite database, and the connection to the database for visualizing and using information on environmental and comfort variables. The second workflow involves the georeferencing of the CFD raster output, the attribution of an ID to the point data, the creation of a point grid in a GIS environment, and the merging of these with the point data on the microclimate. For demonstration purposes, the methodology is tested on a real case study using ENVI-met and ArcGIS Pro
