3D DIGITAL MODELS FOR A WIDESPREAD MUSEUM: THE RENON’S “BAUERNHÖFE”
2019
Abstract. The aim of the paper is to study the characteristics of different 3D digital models (point clouds, mesh, CSG, BIM) for the realization of a museum of historical buildings widespread in the territory of South Tyrol through the 3D modeling of several farmhouses between the towns of Collalbo, Longomoso and Siffiano, in the Renon area. Therefore, moving from a defined case study, the paper proposes a workflow for model choice, use, and sharing considering also users profile.The objective is to create a system that allows, the sharing, both on site and remotely, of farmhouses digital models, information, images and documents found during the research. The purpose is to enhance the terr…
THE VIRTUALIZATION OF CH FOR HISTORICAL RECONSTRUCTION: THE AR FRUITION OF THE FOUNTAIN OF ST. GEORGE SQUARE IN VALLETTA (MALTA)
2020
Abstract. Improving accessibility to Cultural Heritage (CH) is an increasingly urgent challenge today. It is not only a matter of physical inaccessibility but also temporal, considering that part of CH now lost. Fortunately, the most modern technological tools are helping to break down both space and time barriers. In facts, recent advances in representation, 3D modelling and survey methodologies opened new scenarios for valorization and conservation of CH. In particular, the improvement of quality in resolution and sensor sensitivity of cameras allowed to achieve the right level of 3D reconstruction through digital photogrammetry procedures. In the same field, terrestrial laser scanners (T…
MAIN FEATURES OF A 3D GIS FOR A MONUMENTAL COMPLEX WITH AN HISTORICAL-CULTURAL RELEVANCE
2018
Abstract. The last achievements of technologies in geomatics especially in survey and restitution of 3D models (UAV/drones and laser scanner technologies) generated new procedures and higher standards of quality in representation of archaeological sites. Together with Geomatics, the recent development of Information and Communication Technologies (ICT) strongly contribute to document and the Cultural Heritage (CH). The representation and documentation of CH using these new technologies has became necessary in order to satisfy different needs: – for restorers in order to acquire a deep knowledge of the cultural good and to define possible strategies of restoration; – for the conservation of …
THE MAIN PORTAL OF THE CATHEDRAL OF MONREALE: FIRST GEOMETRIC ANALYSIS AND INTERPRETIVE ASSESSMENT OF ARCHITECTURAL FEATURES
2017
Abstract. Nowadays, 3D documentation of architectural assets is becoming a demanding task for the valorisation of Cultural Heritage especially after a restoration project. The 3D documentation can be used for detailed analysis of specific elements, for monitoring the state of conservation and for valorisation actions. The paper describes the results of the 3D close-range photogrammetry survey of the main portal of the Cathedral of Monreale (Palermo, Italy). The Cathedral is one the most important monumental complexes in Sicily that, for its high historical and artistic importance has been inscribed on UNESCO’s World Heritage List since 2015. The main portal of the Cathedral has been recentl…
IMAGE-BASED MODELING TECHNIQUES FOR ARCHITECTURAL HERITAGE 3D DIGITALIZATION: LIMITS AND POTENTIALITIES
2013
Abstract. 3D reconstruction from images has undergone a revolution in the last few years. Computer vision techniques use photographs from data set collection to rapidly build detailed 3D models. The simultaneous applications of different algorithms (MVS), the different techniques of image matching, feature extracting and mesh optimization are inside an active field of research in computer vision. The results are promising: the obtained models are beginning to challenge the precision of laser-based reconstructions. Among all the possibilities we can mainly distinguish desktop and web-based packages. Those last ones offer the opportunity to exploit the power of cloud computing in order to car…
Sustainability in the restoration and management of the historic architecture in Palermo
2015
This research investigates the energy and environmental sustainability in the restoration and conservation of historic buildings. It focuses on the architectural heritage of Palermo, which can be a significant case study for the Mediterranean area. Its objective is to analyse the current energy performance of this historic architecture and its potential for energy improvement. Therefore, it aims at proposing a methodology to combine the enhancement of energy and environmental performances of the historic architecture of Palermo with the need of its material and aesthetic conservation, in the frame of the current regulations.
Rebuilt the space using stone or brick vaulted systems: catching the contemporary challenge of construction tradition
2019
In the recovery and restoration sites, as well as in the versatile word of university research about construction history, its not infrequent to study stereotomy for the re-proposal of stony or tiled vaulted systems, sometimes complex for their constitutive geometry, equipment, preliminary/subsidiary carpentry works. It represents a didactic study-key also in Engineering and Architecture Schools, through laboratories that teach to future designers a know-how that can be easily spent in their professional repercussions.
Innovative, Translucent and Multi-functional Components for the Building Envelope: technological and performance optimization
2017
The paper describes the actions aimed at the technology and performance optimization of an innovative, multi-functional building component made of precast and pre-stressed glass blocks useful for the construction of sustainable building envelopes able to reduce the energy consumption and to produce clean energy from the sun. The design optimization of different sub-components and the choice of the right materials for guaranteeing their good response in terms of mechanical resistance, thermal and acoustic insulation, light transmission, electricity production, integration with other components, dimensional coordination, are particularly described.
Architecture in iron in the city of XIX century Roof structures of theatres and covered markets in Palermo
2016
In post-unification Palermo, components manufactured abroad were usually used for complementary iron structures (greenhouses and skylights, projecting roofs, staircases…), whereas, for more demanding works, more weight was given to the contribution of producers with experience gained in the field of metal construction. Analysis is here carried out on the works of greatest importance, from the roofs of the two major theatres to the roofing of food market structures; the finest technicians were employed and a critical debate was triggered in the city with regard to formal, static and building aspects.
Strategies, Technologies and Novel Components for the Architectural Integration of Photovoltaics
2015
La ricerca riguarda l'integrazione architettonica del fotovoltaico (FV) per il retrofit energetico del patrimonio edilizio esistente e la costruzione di edifici a energia zero (ZEB). L'obiettivo è lo studio e la successiva definizione di strategie, tecnologie e componenti innovativi per l'involucro edilizio che integrino il fotovoltaico, con particolare attenzione verso le tecnologie fotovoltaiche di nuova generazione. Il lavoro si concentra anche sull'ottimizzazione energetica e sull'analisi delle prestazioni di un componente innovativo per il BIPV (Building Integrated Photovoltaics, letteralmente fotovoltaico integrato negli edifici) utile alla costruzione di involucri edilizi sostenibili…
