This paper describes the extension to the urban scale an already applied and developed procedure for individual buildings, which aims to maximizing the exploitation of the existing building components and materials, in a life cycle perspective. The outcome is a tool by which a first survey can be carried on an urban area to guide further refurbishment process.

The digitalization supports this new approach, as the implementation of Building Management Systems (BMS) in Building Information Modelling (BIM) environment allows to link the information collected to a database. The contribution is focused on a case study of the University of Cagliari, the Mandolesi Pavilion, and it is aimed at implementing and improving energy audit procedures by the use of Building Information Modelling.

Through the management of information related to internal and external conditions combined with the design and context data, the built network lead to assess the correct strategy for an adequate hygrothermal behaviour (choosing between active and passive systems for control of indoor air-quality). The expected benefits are a healthy environment, the stable performances of materials, the containment of maintenance costs, the reduction of the use of passive systems in order to cut CO2 emissions.

In this perspective, some research lines have emerged referring to the concepts of smart, intelligent, and green/sustainable buildings. Starting from this analysis, the article aims to highlight how it is possible to synthesize both the environmental quality aspects and the integrated control of a building in the concept of bright green buildings, and how thus a wider conceptual reference framework is necessary: identified in the Bright City based on the implementation of a City Information Modeling (CIM). This methodological framework allows managing the urban transformation operations in an integrated way and represents a synthesis of the current paradigmatic references: sustainability, smartness and resilience.

As past evidences showed that no programmatic action can deal with the unpredictable nature of many risk dynamics, we tried to survey on how the current approach for safety management in the construction industry could be improved. In our previous research the use of Bayesian networks elicited from subjective knowledge were preliminarily tested. Those networks might be meant as a reliable knowledge map about accident dynamics and they showed that a relevant ratio of occurrences fall in "hardly predictable hazards" class, which cannot be warded off by programmatic safety measures. This paper reports the second outcome of our research project, which focused on the development of first elementary fragments, regarding the occurrence of a possible "hardly predictable scenario". Instead of experts' contributions (who, over their carrier, seldom incurred in accidents), we used "legal cases" as an accurate source of information. They suggested which categories of "hidden hazard scenarios" are more likely to happen. We found that the most frequent hidden hazard scenarios are linked to operator's negligence and abnormal behavior, e.g. irregular removal of scaffolding's components, unprotected openings, improper use of PPE, etc. Every pattern determined by legal cases has been formalized by a fragment (i.e. elementary network) of the overall Bayesian network. Finally, all the elementary networks were integrated into a comprehensive intelligent tool for realtime hardly predictable hazards prevention. The final setup, asked for interfacing these intelligent models to a low-level sensor network and used to feed them with inputs about the current state of the context, is discussed too.

The research aims at understanding how to organize and structure the compliance of the building, in order to anticipate users' needs and how the centrality of these requirements can influence the definition of new retrofit models. Firstly, the proposed workflow has been tested on a pilot building with the same use: the eLUX lab, e.g. the Smart Campus Demonstrator at the University of Brescia and then, an adaptation of the developed cognitive concept has been applied to the “Mandolesi Pavilion”, an icon building at the University of Cagliari Campus. This adaptation and the main features transferred to from the experience in Brescia to Cagliari are here presented. ...

Essi sono, inoltre, in grado di rendere disponibile una grandissima quantità di dati sui consumi, le condizioni ambientali interne ed esterne ed i profili di utilizzo che possono supportare la pianificazione di interventi di riqualificazione energetica. In altri termini, i BEMS e i BACS, supportano la fase conoscitiva preliminare agli interventi di riqualificazione, definita "diagnosi energetica" e il monitoraggio ex-ante ed ex-post dell'edificio consente di definire dove l'intervento è maggiormente opportuno e di verificarne l'efficacia. D'altro canto, gli attuali sviluppi in tema di digitalizzazione delle informazioni del processo edilizio, che stanno portando ad una diffusione di metodologie e strumenti di Building information Management, introducono il concetto per cui questi possano fornire un ambiente di immagazzinamento, elaborazione e rappresentazione dei dati acquisiti dai sistemi sopra richiamati. La possibilità di interfaccia con un sistema BIM consente una maggiore correlazione con altre informazioni sull'edificio, come le tipologie costruttive, le modalità di gestione e manutenzione o la presenza di degrado, facilitando una pianificazione degli interventi più efficiente e completa.

The urge of working on built environment is however facing some crucial issues. The first is the lack of documentation on the construction history and on the real constructive layout of existing buildings (in terms of components, installations, plants, etc.). The second is the poor activity in surveying their current status, with reference to use (energy behaviour, real consumptions, etc.) and maintenance (conservation status, previous maintenance works, compliance with current regulations, etc.). These obstacles cause a deep inefficiency in the planning, programming and controlling of requalification and/or refunctionalisation works. Starting from these assumptions, this paper shows the findings of a research shared by the Politecnico of Milan and the Department of Civil and Environmental Engineering and Architecture of the University of Cagliari. It is aimed at testing the use of building information modeling (BIM) to structure the necessary knowledge to evaluate intervention scenarios. The research is focused on the Mandolesi Pavilion of the University of Cagliari, designed by Enrico Mandolesi. It is a highly stimulating architectural object because it incorporates values that require a conservative approach, but at the same time, like most contemporary buildings, it was designed and built for innovation and not for "long duration". The work has actually led to the realization of a BIM model of the case study. It represents the first prefiguration of an approach that develops from construction history and continues with advanced diagnostics on the statical and energy performances of the building. The model formalizes knowledge and information on a significant building, aimed at its management. It allows also the setting of intervention scenarios that can be evaluated with real-time simulations of cost, time and ROI.

La necessità sempre più attuale di procedere ad “adeguamenti normativi” rischia di rendere questo processo molto complesso se letto nei termini delle problematiche relative alla conservazione. il lavoro di ricerca intrapreso sul Padiglione Mandolesi ha l’obiettivo di indagare puntualmente le problematiche appena accennate, con la complicazione di dover lavorare alla conservazione del Moderno. Qui si propone di utilizzare, in alternativa alla verifica meccanicistica della rispondenza ai requisiti normativi legati alla gestione delle emergenze, una metodologia alternativa legata alla modellazione informativa e all’uso dei game engine attraverso la modellizzazione dei comportamenti umani. Lo studio è stato condotto utilizzando i due modelli di simulazione: agent based e narrative driven. Questi modelli presentano entrambi delle limitazion...

The variety of the different subjects involved in carrying out of the building processes, makes the development of integration and cooperation instruments necessary. Through the present work, we suggest a solution to such issues: focusing on Knowledge Management (KM) techniques means to rationally organize the considerable quantity of data/information and to capitalize the consolidated knowledge. A PA aiming at improving the management of the building processes can implement an internal knowledge map to establish and/or make explicit the company standard procedures. The article reports the outcomes of a theoretical research, a work-in-progress, in which the knowledge management techniques are combined with possible applicati...
