Environmental and bioclimatic urban redevelopment: case study of the ancient Mura Latine area in Rome
No full textL'articolo espone i risultati della ricerca chiamata "Caratteristiche bioclimatiche, energetiche ed ambientali del quartiere San Giovanni in Roma, il caso studio delle mura Latine", una ricerca rivolta alla verifica dell'applicabilità dei metodi di analisi e stima del comportamento bioclimatico di un tratto di tessuto urbano caratterizzato da valori storici ed archeologici nel centro di Roma. Lo studio punta anche a sviluppare le strategie progettuali per aumentare la prestazione energetica, ambientale e bioclimatica complessiva, grazie anche all'utilizzo di simulazioni informatiche per orientare il passaggio dalle analisi al progetto.The paper illustrates the synthesis of the research entitled "Bioclimatic environmental and energy characteristics of the San Giovanni district in Rome", a research meant to check the applicability of methods of analysis and to evaluate the bioclimatic behavior of an urban tissue characterized by historical and archaeological values near the centre of Rome. The study is also meant to develop the design strategies to be applied to improve the overall bioclimatic, energy and environmental behavior of the area; it is based on bioclimatic simulation programs as tools to develop methods for tuning transition between analysis and design. Such use is also included in the paper from the point of view of the need to know the appropriate issues to be explored through the use of urban environment simulation in the delicate phase of transition between analysis and design, making the calculation time-efficient, with respect also to the great flexibility of the design in its early stages. Another topic in the paper is explanation of bioclimatic analyses and their inclusion in the initial stages of the design process with no need for specific technical support by expert software users, who are rarely involved by designers in the early design stage for the above-mentioned initial flexibility of the project, or for economic and schedule reasons
Multiscale analysis of minor historical centres and planning of urban regeneration interventions through the integration of Heritage BIM and GIS tools and platforms
No full textThe paper deals with the topic of the regeneration of minor building stock in the context of small Italian historical centres, through the use of ICT (Information and Communications Technology) methodologies and tools for the management and development of sustainable intervention strategies. The problems of accessibility and urban decay were at the core of the following project proposals, aimed at recovering public spaces and implementing new logistic services and infrastructures in Artena, a medieval village in the south of Rome. A methodological approach based on multiscalarity, has allowed the development of a holistic and integrated information model through the interoperability of BIM and GIS tools, aimed at defining strategies for sustainable recovery of the city by reinforcing its resilience and improving its accessibility
Heritage-BIM: the integrated management of the historical centres, the case study of Artena
No full textThe article deals with the use of digital technologies to support the management and regeneration of minor buildings, in particular that of small Italian historical centers, represented by the case study of the medieval village of Artena, located south of Rome. The design of the interventions on the village was accompanied by the parallel design of a new methodology based on the integrated use of GIS and BIM systems and logics. The development of a methodological approach based on multiscalarity and the design of a holistic and integrated information model, supported by a specific Common Data Environment (CDE), led to the definition of strategies for the recovery of the village, according to the themes of the resilience and accessibility
Natural ventilation and passive cooling for energy efficiency of residential buildings in Mediterranean climate
No full textThe upcoming new energy requirements for European buildings impose Nearly Zero Energy standards within few years. In order to
achieve such a result, new buildings will need to combine high performance envelopes, energy-efficient active energy systems, on site
renewable energy production and passive systems. The latter seem the most difficult to be widely implemented in the conventional
buildings, despite their proven effectiveness. Particularly, natural and hybrid ventilation systems in Mediterranean climate have a huge
potential in terms of energy savings and indoor comfort improvement. The main obstacles for a wider use of such systems lie probably in
difficulties and uncertainties inherent in the design and in the predictability of actual performance. The article describes a methodology
to overcome these problems and presents two case studies that illustrate the process and give an example of the possible results.
The design process is articulated through the use of analysis and simulation tools, progressively more detailed. So the general strategies are adapted to the climate and the main building features; site and general building design depend on the microclimate specific
characteristics; detailed design and systems calibration are defined on the basis of internal CFD and sub hourly energy simulations.
Likewise, other aspects of passive design, such as solar systems, are determined through a similar process of progressive deepening
by means of specific simulation tools.
The case studies, two public housing buildings in Tuscany (Italy), are designed on a high energy standard, with passive solar systems, natural and hybrid ventilation strategies, high-efficiency systems, integrated photovoltaic modules and, in one instance, a solar
cooling system. The design process and the estimated performance are illustrated with particular regard to ventilation and cooling
systems. The buildings are expected to have very low energy consumption and a high quality standard for the indoor comfort, showing a good potential for these strategies in Mediterranean climate. Namely, the cooling needs are reduced by a quantity between 74
to 100%, meaning that an effective ventilation systems (combined with other strategies, can get to completely eliminate the need of
mechanical coolin
From Heritage BIM to BPS, A Computational Design-Based Interoperability Approach
No full textThe article deals with the fundamental issue of the interoperability between BIM and BPS in the complex context of historic buildings conservation. As the current tools for the transition from BIM to BPS follow a black-box approach in which it is difficult for the experts to intervene efficiently without doing several parallel operations, this paper proposes a semi-automatic approach that uses Computational Design (CD) to manage the data flow between the two environments. This allowed an interdisciplinary team of BIM, BPS, CD and conservation experts greater control on the scientific coherence of the single operations involved in the process
Integrated numerical analysis and Building Information Modeling for Cultural Heritage
No full textThe use of numerical simulation applied to heritage buildings triggers a tremendous increase in complexity and at the present time, few studies focus on this issue and the problems of their calibrations. The difficulties are affected by many factors: the complex geometry involved, the nonstandardization of building elements, the inertial behaviour of the wall masses, the importance of moisture transport; in short, the complexity of managing the design workflows in a conservation project of historical buildings.
The integration of numerical simulation and Building Information Modeling is not yet automated and relies heavily on the manual steps and the individual experience. The research analyses the high potential of the use of the simulation of building performance, and the computational design along with Heritage Building Information Modeling, with the aim of pushing the three technologies to their potential limits, and promote their evolution towards an easier practical application. The paper presents
an experimental HBIM workflow applied to a case study of a building located in an Italian historic centre and discusses a number of problems that still exist in the application of these workflows. They range from finding a correct set of information necessary for the analysis to the lack of interoperability that still exists between the software, up to the difficulties of the methodological approach. The results show that through a combination of recent open source software constantly evolving, it is possible to overcome some of the obstacles that prevent an effective interoperability between individual software, paving the way for an increasing number of useful solutions in the built heritage conservation.The use of numerical simulation applied to heritage buildings triggers a tremendous increase in complexity and at the present time, few studies focus on this issue and the problems of their calibrations.
