A BIM-Based Framework to Visually Evaluate Circularity and Life Cycle Cost of buildings

The Circular Economy paradigm seeks to shift products and systems from linear to “closed loop” life cycles applying specific business models and strategies to their designs and lifelines. The implementation of the circular economy in buildings depends on the efforts made by all the stakeholder involved in the life cycle of a building, where it can draw most of the benefits if the application of a circular business model is planned during the design phases. Building Information Modelling is an approach that helps designers in creating and managing semantically rich 3D-models describing the status of the building over its life cycle. In this paper, a BIM-based framework for evaluating the application of circular business models of buildings from the circularity and the life cycle cost points of views is proposed

Ripensare la gestione dell’azione pubblica per i nuovi bisogni abitativi: i casi delle trasformazioni urbane “interrotte"

Realizzare e gestire opere pubbliche efficienti, a impatto ambientale controllato e in grado di costituire contributi concreti al welfare urbano, rappresenta una sfida di innovazione e crescita del governo delle trasformazioni urbane, alla quale si è spesso risposto in modo inadeguato negli ultimi decenni nel nostro paese, anche a causa della crisi del comparto delle costruzioni avviatosi parallelamente alla più generale crisi finanziaria dal 2008. Il presente contributo, partendo dal caso studio di alcune “trasformazioni urbane interrotte”, intende proporre una riflessione critica sulle politiche e sulle modalità di intervento attuate in materia di gestione delle opere pubbliche, proponendo in alternativa modelli e forme innovative di azioni, orientate alla condivisione e alla circolarità, da intendersi come opportunità di cambiamento

Living Lab as enabler of new technologies in Public Administrations: The B@ARCA project

The research aims to assess whether the Living-Lab methodology can facilitate the introduction of new technologies within a Public Administration (PA). Previous research explored the challenges and benefits derived from the introduction of ICT into public organizations through the presentation of qualitative case studies. None of these works evaluates if, and eventually how, the introduction of new technologies in Public Administrations (PAs) can be facilitated by the Living Lab (LL). This paper attempts to close this gap by presenting the results of B@ARCA - BIM at ARCA, a research project where the development of Building Information Modelling (BIM) based methodologies and technologies and their introduction into a Public Organization has been carried out embracing the Living Lab methodology. In detail, the project objective is to equip the ARCA agency, the authority in charge of the management of the social housing asset in the Puglia Region, with innovative technological solutions useful to improve the maintenance work of the old and great heritage. The level of acceptance of the new technology, measured through quantitative questionnaires, resulted in increased after the completion of the Living Lab development activities. These initial results may encourage public administrations to use the Living Lab to expose their employees to not just BIM but also the series of new technologies needed for the digitization of the public administration

Building Information Modeling for Cultural Heritage: beyond asset modeling. A pragmatic comparison of literature case studies

The Building Information Modeling is an innovative approach based on two main pillars: new technologies and a collaborative work environment. It includes the creation of a digital container where all the information about the building and its lifecycle are dynamically allocated. Whilst the use of BIM in the management phase represents a unexpressed potentiality, the exploitation of the 3D virtual model could give a multiplicity of benefits, above all as regards big and historical buildings that are complex to manage. This paper wants to give a contribution to clarify what happens after modeling the cultural heritage with the principles of HBIM –Historical BIM- and managing its documentation. The authors analysed, with a pragmatic approach, a series of case studies documented in literature. The analysis led to highlight strengths and weakness of current approaches and a possible framework to overcome them

Accumulation and erosion of Mars south polar layered deposits from subsurface radar sounding

Mars’ polar regions are covered with ice-rich layered deposits that potentially contain a record of climate variations. The sounding radar SHARAD on the Mars Reconnaissance Orbiter mapped detailed subsurface stratigraphy in the Promethei Lingula region of the south polar plateau, Planum Australe. Radar reflections interpreted as layers are correlated across adjacent orbits and are continuous for up to 150 kilometers along spacecraft orbital tracks. The reflectors are often separated into discrete reflector sequences, and strong echoes are seen as deep as 1 kilometer. In some cases, the sequences are dipping with respect to each other, suggesting an interdepositional period of erosion. In Australe Sulci, layers are exhumed, indicating recent erosion
