RETROFITTING DETENTION BUILDINGS OF HISTORICAL-CULTURAL INTEREST. A CASE STUDY IN ITALY
2021
Penitentiary buildings in Italy include many buildings of undoubted historical and architectural importance. These have been, or will soon be, subject to structural changes necessary to adapt their spaces to the current regulations of prisons. The idea of punishment itself has changed over the centuries, so it is a physiological necessity to adapt existing buildings accordingly. When, however, such buildings date back centuries, they should not be considered a mere container but a historical testimony rich in meaning for the entire nation. The characteristics of the materials, distribution, and what these buildings have represented for the city should be the object of study and protection, …
Towards a Holistic Approach to Retrofitting: A Critical Review of Stateof-the-art Evaluation Methodologies for Architectural Transformation
2017
The building sector is well known to be responsible for a considerable part of the total European energy consumption. In the endeavor to implement radical reductions, there is an identified potential in addressing the existing building stock through deep renovations. These renovations make up complex, highly interdisciplinary systems. They involve stakeholders across a broad spectrum of disciplines and potentially affect the lives of a large number of occupants. The involved people bring different understandings of value in sustainability into a project and judge the outcome according to this understanding. As a response to this, a number of sustainable assessment methodologies for the buil…
Towards a Holistic Methodology in Sustainable Retrofitting: Theory, Implementation and Application
2017
Sustainability paradigm foresees a balance of energy production and consumption with no, or minimal, negative impact on environment (within the environmental tolerance limits). It gives an opportunity to a country to employ its potentiality of the social and economic activities. An overview of recent researches about building renovation context demonstrates the lack of an appropriate methodology and decision support framework -by compounding the typical challenges of sustainable retrofitting from theory to implement stages- that takes into account the retrofitting projects throughout more comprehensive insights and perspectives. It calls, therefore, for a deep building renovation approach. …
STRATEGIE PER LA RIQUALIFICAZIONE ENERGETICA DELL’EDILIZIA SCOLASTICA IN CLIMA MEDITERRANEO
2018
Il patrimonio edilizio italiano è composto principalmente da costruzioni realizzate nel secondo dopoguerra, quando la speculazione economica e l’urbanizzazione hanno prodotto edifici con caratteristiche di scarsa qualità architettonica ed energetica. Agire sul rendimento energetico degli edifici esistenti, adattandoli alle caratteristiche richieste dalla normativa, a parità di condizioni di comfort, rappresenta una strategia importante per la riduzione dei consumi energetici e per la tutela dell’ambiente. Attraverso l’applicazione di tecnologie e metodologie innovative e la scelta di investimenti adeguati, il retrofit energetico può rappresentare, oggi, la principale opportunità di crescita…
Reaching net zero energy at the neighbourhood scale: feasibility studies in the south of Italy
2020
Il concetto di “edificio a energia netta zero” è stato recentemente implementato in tutti i regolamenti dei paesi europei. Tuttavia, l’approccio dettato dall’Europa si concentra principalmente sulla scala dell’edificio singolo, tralasciando alcuni aspetti riguardanti ad esempio l’interazione di generazione e carico tra edifici e le interazioni energetiche tra edifici. L’obiettivo di questo studio consiste nell’applicazione della definizione di net zero energy building ad un gruppo di edifici ubicati nell’Italia meridionale e caratterizzati da una destinazione d’uso variegata. Lo status quo di una ventina di edifici è stato simulato in ambiente energy plus e sono state successivamente selezi…
Energy performance of architectural heritage: characteristics of the historic buildings in Palermo
2015
The current researches on the energy and environmental improvement of historic architecture aim to develop strategies respectful of its aesthetic and material features. This requires a deep knowledge of the characters strictly connected to a local context. This paper focuses on the historic architecture of Palermo and analyses, among its features, those which particularly influence its energy and environmental performance. For this purpose the building typologies introduced by the urban regulations can be useful for a categorization on the basis of the most recent European researches.
Energy rehabilitation of a nursery school in Sicily: winter and summer behaviours
2004
Following a previous work, concerning the energy audit of a nursery school belonging to the public building park of the town of Palermo, some further analyses have been conducted. These mainly refer to the environmental performances of the school that are assessed with regards to different interventions involving the envelope (the glazed part, particularly) and the surrounding spaces. The interventions are hierarchised by means of suitable indicators concerning energy, environment and economy issues. Finally a simple graph is proposed that visually summarises these indicators for each proposed action.
Vegetation and Thermal comfort in temperate areas: proposal of an integrated methodology for urban and building retrofit
2014
The paper points out the main outcomes of a doctoral research carried out at the Department of Architecture of the University of Palermo, aimed at investigating the issues of environmental, social and economic sustainability related to the recovery of the existing building stock with focus on social housing. In particular, starting from the analysis carried out on a real case of the city of Palermo, through the use of specific simulation tools, the research provides a new methodology for the design and the assessment of the effectiveness of plants and Building-Integrated Vegetation systems used as a cost-effective solutions for urban and building retrofit, contributing to new knowledge and …
GLOBAL SAVING EVALUATION THROUGH A RETROFITTING ACTION
2014
The paper shows a work that was carried out by the authors as members of the PADesign Company, academic spin off of University of Palermo. Currently, energy retrofit of existing building has become an important goal, because it is now widely recognized that the buildings are one of the main causes of CO2 production and of non-renewable energy consumptions. To act on the energy performance of existing buildings (adapting their performances to those required by regulations) is an important strategy to reduce energy consumptions since they are much more than new buildings. Through the application of innovative technologies and methodologies and the choice of appropriate investments, the retrof…
Strength and ductility of RC jacketed columns: A simplified analytical method
2016
Abstract Reinforced concrete (RC) jacketing is a common method for retrofitting existing columns with poor structural performance. It can be applied in two different ways: if the continuity of the jacket is ensured, the axial load of the column can be transferred to the jacket, which will be directly loaded; conversely, if no continuity is provided, the jacket will induce only confinement action. In both cases the strength and ductility evaluation is rather complex, due to the different physical phenomena included, such as confinement, core–jacket composite action, preload and buckling of longitudinal bars. Although different theoretical studies have been carried out to calculate the confin…
