PATRIMONIO ARCHITETTONICO E TIMELESS TIME : PER UNA PERMANENZA TEMPORANEA
2018
Com’è avvenuto per le precedenti rivoluzioni industriali, la digitalizzazione non ha sortito effetti soltanto nei processi e nei prodotti tecnologici. Tra le sue dirompenti conseguenze sulla società e sugli individui, l’emergere di una diversa concezione del Tempo sta già condizionando il campo operativo e soprattutto teoretico dell’ambiente costruito connotato da significati culturali. Inusitate forme di memoria mettono in crisi la visione tradizionale di patrimonio, fondata su una visione lineare del tempo che separa nettamente il Passato dal Futuro, lasciando al Presente un mero ruolo da passatore. Superata la presunta immutabilità, ambizione di ormai obsoleti obiettivi conservativi rigi…
Energy savings for indoor lighting in a shopping mall: A case of study
2018
The paper presents an application of energy saving in the final users. In particular, the case of study evaluates the energy consumptions of a big shopping mall, located in the middle part of Italy, illuminated by fluorescent lamps. In order to reduce the energy demand, the case of study shows a first solution based on LED lamps; a second step considers the adding of a building automation system, maximizing the energy saving, thanks lighting sensors that module the luminous flux taking in count of natural lighting through skylights.
Smart lighting in a historic context: a case study
2017
Purpose The purpose of this paper is to address a project for lighting an old town in Italy. Its originality lies in the holistic approach that aims to fulfil several objectives. One is to reduce energy consumption by using efficient lamps and advanced control systems; the second one is to make the network viable and useful for many purposes by integrating ICT devices; the third one is to provide a new identity to the older part of the city by using new technologies and design concepts; while the last one is to ensure street and pedestrian safety according to codes and standards. Design/methodology/approach The plan of the city of Bagheria and the stock of luminaires of the city are analys…
Scenarios of Climatic Resilience, Economic Feasibility and Environmental Sustainability for the Refurbishment of the Early 20th Century Buildings
2019
This paper aims to examine the theme of energy retrofit within the circumscribed field of refurbishment interventions on load-bearing masonry buildings built in the early 20th century. These include a remarkable share of the fabric of many European cities and, in particular, they can be found in geographical areas characterized by a Mediterranean (mild) climate. The main objective is to increase the climate resilience of the buildings by verifying the economic feasibility and the environmental sustainability of the interventions at the same time observing the specific architectural features of the buildings. We put forward alternative retrofit solutions carrying out synoptic comparisons of …
The Waterfront Theorem: an integrated and creative planning approach
2016
Waterfronts are sensitive interfaces between land and sea, creative interfaces between urban and environmental components, social interfaces between nodes and networks. They not only coincide with the areas of infrastructure that are gathering on the coast, not only with the shoreline or the environmental components of the coastal territories. They are hired by the project as complex interaction of crossing flows, stratified identity of urban communities: fundamental element of the environmental system, synthesis of landscape, space and community, a place of solidification of the identity of the social, cultural and economic community (Carta, 2009). The management of urban interface of wate…
Visually low-impacting methods for the measurement of parameters related to IAQ risk indicators in exhibition halls
2021
Microclimate for cultural heritage plays a fundamental role in the degradation process of artefacts exhibited in museums. Generally, the Indoor Air Quality (IAQ) monitoring inside museums is based on conventional measurements of thermo-hygrometry parameters and longtime averaged measurements of atmospheric pollutants’ concentration. Unfortunately, all these approaches require electric supply and are usually characterized by a noticeable visual impact on the exhibition space, which clearly negatively affects the visitors’ experience. This paper intends to revisit and discuss a methodology (and its test application on field, to estimate the risk of damage of three artefacts displayed in an ol…
Life cycle energy performances and environmental impacts of a prefabricated building module
2018
Abstract The paper explores the energy performances and environmental impacts of a prefabricated building module located in Messina (Sicily, Italy) through an approach that combines both the non-steady state building simulation and the Life Cycle Assessment methodology. The building uses renewable energy technologies and is usable in emergency situations or as simply temporary housing. Results show that the building module causes the emission of 1.5 t of CO2eq/m2 and consumes 29.2 GJ/m2 of primary energy during its life cycle. The building achieves the Net Zero Energy Building target even if it has relevant environmental impacts in the materials production stage (72% on average of the total…
The Museum of Engines and Mechanisms. More Than a Century of History of Technology
2015
The Museum of Engines and Mechanisms of the University of Palermo has preserved more than 300 pieces, which collectively narrate the evolution of science and technology in the field of fluid machines and their components and testify to the development in scientific disciplines, technologies and industrial applications over the course of more than a century. A rigorous chronological path through the various typological groups allows for a historical walk through the last 150 years, in the area of automotive, airplanes and marine engines; hydraulic machines and stationary engines; mechanical measurements and laboratory devices for scientific and educational purposes. The collection is availab…
Special Issue “Smart Urban Lighting Systems”
2020
The design and operation of multifunctional infrastructures for public lighting as well as their impact on the urban environment and citizens’ life is today of great interest. The cost of energy for public lighting is often an issue for the budget of municipalities. Furthermore, researchers’ and designers’ attention is increasingly focused on aspects of public lighting not directly valuable through economic factors. Starting from the “quality” of the light environment, looking at citizens’ visual comfort, the light has to be considered as an instrument to improve the urban context and objects therein (including buildings). Indeed, urban degradation (lack of infrastructures, maintenance, ser…
Architectural Perspectives in the Cathedral of Palermo: Image-Based Modelling for Cultural Heritage Understanding and Enhancement
2015
Palermo off ers a repertoire of both artistic and architectural solid perspective of great beauty and in large quantity. This paper addresses the problem of the 3D survey of these works and their related study through the use of image-based modelling (IBM) techniques. We propose, as case studies, the use of IBM techniques inside the Cathedral of Palermo. Indeed, the church houses a huge and rich sculptural repertoire, dating back to 16th century, which constitutes a valid field of IBM techniques application. The aim of this study is to demonstrate the e ffectiveness and potentiality of these techniques for geometric analysis of sculptured works. Indeed, usually the survey of these artworks …
