Il lavoro rappresenta il primo studio sistematico sulla produzione di tetradrammi da parte di Leontinoi, le cui emissioni, tra le maggiori testimonianze dell’arte incisoria siceliota, si concentrano tra gli anni Settanta e Venti del V secolo a.C. La ricerca affronta la coniazione di centosessantadue serie di tetradrammi, commentate attraverso la ricostruzione delle sequenze dei conii, l’analisi stilistico-formale dei tipi monetali, il confronto con i nominali minori, nonché lo spoglio dei ripostigli noti, offrendo nuovi elementi e considerazioni nell’ambito degli studi di numismatica e arte siceliote. The book contains a completely new systematic study on the tetradrachms struck by Leontinoi in the 5th century BC. Among the greatest testimonies of the Greek art in Sicily, the one hundred and sixty series of tetradrachms collected here are commented on through the recognition of die-sequences, the figurative analysis of coin types, the relationships with minor denominations, and, finally, through an upgraded survey on the most important coin finds of Sicily.

Maintenance budget appraisal and allocation is a fundamental activity for the definition of an effective Facility Management (FM) strategy. Once the maintenance policy is set by the assets’ owner, facility managers are asked to compare different maintenance strategies (i.e. preventive vs. corrective) in order to provide a reliable and cost-effective maintenance budget. This can be hindered by unavailability of data for maintenance of building components. Nowadays, Building Information Modelling (BIM) provides plenty of data, but procedures are seldom focused on maintenance costs appraisal and this frequently leads to an intensive data re-elaboration. The objective of this research is to provide a precise maintenance budget appraisal according to different maintenance strategies through the Facility Condition Index (FCI), calculated starting from data stored into an Industry Foundation Classes (IFC) model. Data are stored in IfcAsset elements, using the related property sets. To overcome calculation needs, some additional attributes may be associated to elements and stored in custom property sets. The results of this research are a set of data, procedures and tools that allow the quantification and planning of maintenance expenditure, allowing a proper budget allocation. These procedures and tools answer the need of both designers during new constructions (to prepare the maintenance plan, as required by current Italian laws for public buildings) and asset managers during the digitisation of existing buildings (to store maintenance data and to rely on better appraisals). In this paper a demonstration is presented, with the purpose of showing the proposed methodology and tools. The demonstration has been carried out on some of the architectural and Mechanical, Electrical, Plumbing (MEP) components that mainly contribute to the annual maintenance expenditure., IN_BO.

Rating systems are assumed as instruments to endorse architectural quality, reliability, energy efficiency, economic convenience and finally expose a sustainability label. Moreover, these tools can be tied to a BIM model. The aim of this research is to set up a lean methodology to fulfil CESBA requirements through Construction to Operations Building information exchange – COBie in project on existing buildings adopting the BIM Bronze approach by UK Ministry of Justice - MoJ. This will allow to develop a semantic model and to extract sustainability reports in a post-construction phase, thereby minimising the cost of gathering information on existing buildings. An illustrated example regarding energy criteria of CESBA protocol will be presented to further the proposed approach., TECHNE - Journal of Technology for Architecture and Environment, TECHNE 13 (2017): Theories Practice Design

Aim of this research is to deliver a system of procedures and instruments that allows comparing different scenarios of restoration and retrofit of existing buildings applicable each time a relevant decision about the asset has to be made. The system developed takes advantages of Building Information Modeling (BIM) and Analytical Hierarchy Process (AHP), thus to focus on main clients’ needs. Decisions about real estate assets are frequently made by managers with incomplete and scattered data, not sufficient to fully support the decision making process. Using a BIM model as a central repository of information could strongly support to compare objectively different scenarios and consequently to decide the application of a multi-criteria matrix involving management, energy, economic and social issues. BIM and BEM (Building Energy Modelling) techniques have a wide potential and analysis capabilities; however, they are often adopted without an integrated framework, causing missing performances and costs overrun. The result is a system enabling to analyze the asset, to produce BIM and BEM models ready to include life cycle data, to evaluate feasible alternatives and scenarios and to extract relevant performance indicators for decision makers’ support. An existing office building in Milan representing an awkward field for intervention is the case study for the system application. While the tools and software adopted are commonly used, the system of procedures developed by the authors can be considered as an ensemble of workflows otherwise typically used independently. Using them together enhance the decision process providing data on which to set up a strategic plan of the refurbishment considering costs, continuity in occupancy and energy efficiency.
