Public residential buildings make a large portion of the European existing stock and they quite often require deep renovation interventions. A methodology for setting priorities and targeting regeneration investments should be defined relying on the increasing use of building information modelling (BIM) tools even for managing existing buildings. T...
La crisi sanitaria che ha colpito con grande vigore il nostro Paese ha palesato una serie di fragilità dei nostri territori urbani che non può lasciare indifferenti gli studiosi della città e dei suoi processi. Il grande numero di infetti che si sono riversati nei presidi ospedalieri ha di fatto congestionato il sistema sanitario anche per tutta un...
Nell’attuale contesto di crisi ambientale la riduzione dell’impatto del costruito è di grande importanza
e, nello specifico, appare fondamentale il tema della gestione sostenibile degli edifici
pubblici con valenze storiche. Tali edifici rappresentano elementi diffusi e vitali delle nostre città
sia da un punto di vista culturale, declinandosi in t...
The aim of this paper, in line with the 2030 European Agenda and 2021 Italian “Recovery and Resilience Plan” objectives, is to define an evaluation methodology and tool to support public administrations to detect buildings, currently unused or underused, that might be apt for transformation interventions. The focus is on historical Italian healthca...
In densely populated cities, the lack of green spaces has a negative impact on urban health. Green roofs are an innovative solution to introduce natural elements into compact urban contexts. This study proposes a holistic framework for the implementation of green roofs that takes into account the parameters that influence the choice of the most app...
Nature-Based Solutions offer a concrete opportunity to integrate nature into cities and strengthen their resilience, in response to global challenges related to climate change, biodiversity loss, and water management, which are exacerbated by urban expansion and its impacts on the built environment. This study aims to analyze various European polic...
Seismic risk in Italy is significant due to its high population density, the presence of large historic centres, the existence of diffused ancient hamlets in inner areas, and a built heritage consisting largely of old buildings. It is impera-tive to adopt strategic approaches focused on reuse, restoration, and adaptation to preserve historical and...
Public real estate management is a complex issue due to the large number of buildings involved and the general state of conservation. Many buildings are unused or underused and regeneration intervention are needed. The aim of the presented research is to define an evaluation methodology – based on digital twins of buildings – to support public stak...
The Covid-19 pandemic underlined the positive role of public green spaces for the physical and mental health of citizens forced into long periods of immobility and social distancing. In cities with high population density, these restrictions have underlined the need to increase public green spaces and their accessibility. Indeed, green spaces have...
In the frame of developing sustainable, reliable, and regenerative interventions on existing buildings, namely on large-scale public housing, the implementation of functional, technological, and effective strategies is devoted to thoroughly assessing the transformability of buildings using trustworthy performance indicators. With this aim, in the p...
This chapter offers a review of the main methods and approaches employed in the evaluation of existing buildings. Evaluating existing buildings is a crucial step in understanding their condition, identifying potential challenges, and determining appropriate strategies for improvement or redevelopment. With the increasing importance of sustainable d...
The regeneration of great-size suburban housing buildings is a holistic process that involves various disciplines and scales.
This chapter introduces the main indicators able to describe and evaluate in a rapid manner the seismic risk of housing buildings considered in this manuscript. The weakness of buildings is evaluated based on their probability of collapse and extent of damages while transformability evaluations are performed evaluating the effectiveness of retrofit...

This chapter describes the weaknesses and the main critical issues housing buildings, especially public social housing ones, are facing in terms of dwelling layout and dimensions, structural, and energetic behaviour. Data showing the global impacts of the housing sector and the distribution based on the period of construction are provided.
This chapter examines the case study of Rome, specifically focussing on the great-size housing complexes built during the 1970s and the 1980s. It explores aspects such as urban dimension, typology, construction techniques, prefabricated building components, and the energetic behaviour of the building envelope. The chapter provides valuable insights...
This chapter offers a comprehensive framework that explores various approaches to intervene in existing public housing, underlining the challenges that emerge from standard interventions and demolition/reconstruction processes. In addition, it presents a collection of best practices for large-scale housing regeneration. By examining these approache...
This chapter introduces the main indicators able to describe and evaluate the typological aspects of housing buildings. Indicators are divided into two main categories related to the analysis of weakness and transformability and applied on case studies selected within the framework of great-size public social housing buildings realised in Rome duri...
The paper deals with FE nonlinear analyses of Portuguese adobe masonry by means of nonlinear shell elements. A nonlinear constitutive model is calibrated and validated onto two different experimental full-scale case studies, before its application for structural analysis at building scale. The model proved to be able to capture in-plane failures as...
The seismic vulnerability assessment of monumental buildings is a complex task. Several uncertainties mine the reliability of evaluations. Within historical buildings, churches appear as particularly vulnerable objects, prone to instabilities and collapse when undergoing seismic loads. Global and local collapse mechanisms related to in plane and ou...
The reduced drainage capacity of the soils, common to various European realities, is also evident in Mediterranean urbanized contexts, such as the city of Naples, where the central areas suffer from scarce permeable green surfaces. The focus of this work is on the large monumental hospitals in the center which, due to their size, go beyond the buil...
In Italy the Covid-19 pandemic has revealed infrastructural and operational fragilities of the healthcare system, as well as a profound need for building modernization and upgrade as it emerges from the planned investments of the PNRR too. The Campania Region confirms the national trend in terms of consistency and age
of the healthcare real estate,...
The historical hospitals of Naples represent a significant heritage section of existing buildings. The city is an important case study, not only for the quantity of monumental hospital structures in the urban context, but for clear characteristics that define their values, from the artistic-cultural richness to the typological and constructive qual...
A large part of the Italian territory is characterized by a spatial organization structured in small towns, with natural and cultural resources, vast material and immaterial heritage, and economic potential. All features often mirrored by a limited accessibility to essential services (transportation, health, and education systems), depopulation and...
The COVID-19 pandemic has outlined the need to strengthen the resilience of healthcare systems. It has cost millions of human lives and has had indirect health impacts too. Hospital buildings have undergone extensive modifications and adaptations to ensure infection control and prevention measures, and, as it is happened following past epidemics, t...
The Italian public real estate counts many historic buildings, commonly underused
or degraded. In the Campania Region more than 1,900 structures built before 1980
have a recognised cultural value. Moreover, in the aftermath of the COVID-19 crisis,
a renovated interest in the field of healthcare services, architectural heritage and
climate change ha...
Even before Covid-19 although in the very center of the old town and historic center of Naples there were abandoned buildings and complexes, uninhabited and unused for decades. The cause is attributed to multiple reasons such as functional obsolescence, failure to adapt to intervening European standards in terms of hospital construction, technologi...
Even before Covid-19 although in the very center of the old town and historic center of Naples there were abandoned buildings and complexes, uninhabited and unused for decades. The cause is attributed to multiple reasons such as functional obsolescence, failure to adapt to intervening European standards in terms of hospital construction, technologi...
The history of cities is closely linked to the success of monumental hospitals (MHs). In Naples, MHs are several and varied; however, some recurring elements can be identified, such as the presence of an inner open space, with artistic and environmental value, around which these structures are organized. Over the years, MHs have been partially aban...
Nel corso del Novecento il numero di conventi ha seguito l’andamento del numero di religiosi.
Così, se in un primo momento si assiste ad una fase di costruzione di nuove “case religiose”,
dagli anni ’60 in poi in Italia, e analogamente nel resto d’Europa, si riscontra una riduzione del
numero di vocazioni con un conseguente abbandono di molti edifi...
Il patrimonio edilizio italiano, relativo agli ambiti ospedalieri e alle strutture socio-sanitarie, è – per
caratteristiche tecniche, costruttive e formali – quasi sempre complesso e difficilmente riconducibile
a schematismi tipologici di immediata lettura e comprensione. Molto spesso esso patrimonio è determinato
da processi costruttivi e “sedimen...
This article addresses seismic vulnerability assessment at an urban scale using mechanical methods, more specifically potential improvements by involving typological curves instead of standard capacity curves and by using accurate displacement demand determination for reliable building damage prediction. The impact in terms of damage grades is comp...
Nowadays, energy retrofit interventions on the existing building stock are of paramount importance towards energy consumption and emissions reductions in the construction sector. Such interventions are also crucial in the view of increasing cities resilience with respect to the intensification of frequent extreme weather events, such as cold spells...
La pandemia da Covid-19 ha posto importanti sfide, in tutto il mondo e in particolare nel nostro Paese, nella gestione del rischio sanitario, tali da richiedere misure urgenti in materia di contenimento e gestione della emergenza epidemiologica.
L’afflusso massiccio di pazienti, affetti da malattie altamente contagiose, ai dipartimenti di emergenz...
Nel panorama attuale, la riqualificazione energetica del patrimonio costruito è di fondamentale importanza per ridurre i consumi e le emissioni che provengono dal settore delle costruzioni. Questi interventi inoltre sono di primaria importanza anche per aumentare la resilienza delle città nei confronti dei fenomeni climatici estremi, sempre più fre...

The programs of 2030 Agenda define some objectives related to construction including the increase in housing, the promotion of social inclusion and the upgrading of healthcare structures. The main objective of the research is the definition...
Linee guida per la manutenzione e il recupero del patrimonio esistente Premessa. "Cento misure ed un taglio solo" è un detto in grado di sottolineare con forza la necessità, prima di agire, di valutare accuratamente. È in espressioni come questa che risiede il senso di "ripensare le progettualità e le modalità di intervento": la ricerca accademica...
La casa, i luoghi e i piani: l'eredità del I Peep Premessa. L'edilizia "popolare", nella storia, è stata un elemento centrale per l'evoluzione delle città europee. La sua affermazione, fin dalla fine del XIX secolo, parallelamente al miglioramento delle condizioni abitative delle classi operaie, coincise con l'affermazione di livelli elevati di qua...
Ein Grossteil der Todesopfer und Gebäudeschäden bei stärkeren Erdbebenereignissen weltweit ist auf den Einsturz von Mauerwerksgebäuden zurückzuführen. Dieser ist oft Folge eines Versagens der (tragenden und sekundären) Mauerwerkswände quer zu ihrer Ebene. Bei der Überprüfung der Erdbebensicherheit von Mauerwerksgebäuden mit flexiblen Deckenscheiben...
The nonlinear seismic displacement demand prediction for low-period structures, i.e., with an initial fundamental period situated in the plateau of design response spectra, is studied. In Eurocode 8, the computation of seismic displacement demands is essentially based on a simplified method called the N2 method. Alternative approaches using linear...
All the acceleration time-histories used in the computations are available for download. They are stored separately. A folder contains the 12 recordings after slight modification to match the corresponding design spectrum (for seismic zone Z2, i.e. agd=1 m/s2). The text files contain the acceleration time-histories in row(s) with a time step of 0.0...
Among the various natural hazards, earthquakes remain a major source of human casualties and economic losses. It is a well-known fact that earthquakes do not kill people; buildings that collapse during earthquakes kill people. Thus architects, civil engineers and urban planners should work in the way of transforming existing cities into resilient s...
Assessing seismic vulnerability at large scales requires accurate attribution of individual buildings to more general typological classes that are representative of the seismic behavior of the buildings sharing same attributes. One-by-one evaluation of all buildings is a time-and-money demanding process. Detailed individual evaluations are only sui...
After destructive earthquakes occurred in Italy between 2009 and 2016, the Italian Parliament approved in 2017 a new version of the Sisma Bonus, which includes Guidelines for the classification of the seismic risk of buildings. In Sisma Bonus, the seismic risk is evaluated through two methods: simplified or detailed. In this paper, the simplified a...
Recent events around the globe are evidence that earthquake action is still a threat for many structures. Low replacement and retrofitting rates of urban housing mean that many buildings do not comply with seismic actions defined in present-day seismic codes and thus, important post-seismic assessment activities are still to be expected. City-scale...
In Europe, computation of displacement demand for seismic assessment of existing buildings is essentially based on a simplified formulation of the N2 method as prescribed by Eurocode 8 (EC8). However, a lack of accuracy of the N2 method in certain conditions has been pointed out by several studies. This paper addresses the assessment of effectivene...
During the 70’s and 80’s, affordable housing production in Europe faced the huge
emergency caused by rising urbanization. In suburban areas of European main cities,
megastructures appeared, drawing visible marks in urban fabric. Megastructures were
planned to synthesize residential functions and all existing services of traditional city in
unique b...
In this study, the impact of typological capacity curves and modified N2 method are investigated independently. The results on the two case studies shows that both refinements contribute to enhance the seismic vulnerability assessment at urban scale. The influence of the two factors relies on the distribution of Swiss types in the general building...
Earthquakes do not kill people, buildings do. Transforming existing cities in earthquake resilient systems should be the main goal for researchers in the field of the seismic analysis of entire towns. Providing means for realistic disaster risk scenario can help decision makers in pre-and post-earthquake management and save lives and goods. Two mai...
This paper addresses seismic vulnerability assessment at urban scale. Particularly, it focuses on the differences in damage distribution obtained from the application of several simplified methods for displacement demand determination. The results obtained for two cities of Switzerland (Sion and Martigny) highlight the related impact. Displacement...
Earthquake-design approaches in regions with low to medium seismic hazard often focus on the
protection of inhabitants. Therefore, some structural damage is accepted. In addition, large parts of the building stock have usually been built without considering seismic limit states. Thus, earthquake events lead to large-scale post-earthquake assessment...
This paper addresses seismic vulnerability assessment at an urban scale by focusing on the displacement demand determination for building damage prediction.
The study is based on the comparison of urban seismic damage distributions obtained by the displacement demand computed using non-linear time-history analysis (NLTHA) with three simplified meth...
In Italy, after the destructions of World War II, due the particular development of economy and the political decision in the field of reconstruction, a government option for building construction industrialization comes up only at the beginning of ‘60s. A wide number of different proposals of building sector industrialization came from technicians...
L'articolo propone una lettura dell’ambiente costruito al fine di esaminare le caratteristiche proprie degli edifici esistenti in funzione della loro predisposizione a subire interventi migliorativi. Lo studio si basa sull’indagine delle caratteristiche tipologiche, strutturali ed energetiche dei complessi residenziali pubblici di grande dimen¬sion...
Seismic assessment of existing heritage buildings remains a challenging task. There is a high level of complexity and uncertainty compared with the assessment of standard buildings. Heritage masonry churches are usually prone to partial collapses during earthquake due to local loss of stability, and exhibit particular seismic vulnerabilities. An im...
Italian territory is particularly sensitive to seismic actions. The Amatrice earthquake on August 24th 2016 confirmed this aspect. Such an event, nothing but extraordinary, has been able to cause huge and tragic damages. The direct knowledge of building features is the only prior measure to face seismic events. In order to get a realistic scenario...
Nowadays in Rome public housing suburbs face several critical issues, both physical and social: buildings obsolescence, state of neglect of open spaces, inhabitant's sense of segregation and lack of social inclusion. These critical issues cause a huge reduction in inhabitant's quality of life. The regeneration of such areas should become one of the...
All’interno delle attività della ricerca ‘Abitare Tor Bella Monaca’ il gruppo di lavoro ‘Patrimonio Edilizio’ si è posto come obiettivo quello di investigare le conseguenze dirette che l’approccio alla città pubblica
della grande dimensione degli anni ’70 e ’80 a Roma ha avuto sulle caratteristiche tipologiche
e costruttive dell’edificato. Si è cer...
The large-dimension housing complexes in Rome have grown since the late ‘60s as a result of the 1st PEEP planning of 1964. The plan tried to face the large housing emergency caused by the rising urbanization (Albano, 2001). The peripheral areas of the city started to be filled with several neighborhoods in sharp break with the close urban fabric: h...
Urban development is facing new challenges to allow the evolution of the environment, in accordance to sustainability principles. In this context, decision makers have to answer to three main issues: how to intervene on the existing compact cities? How to combine and develop interventions on different scales? How to move from requalification to reg...
In the last decades, the issues related to the homelessness have been getting worst due to the reduction of investments dedicated to urban welfare. Emergency is the word which describes the current situation along with the lack of infrastructures at urban level. The first step to deal with this topic consists of analysing the former design solution...
The authors address the salient aspects of the interaction between domestic environment and health in the current housing, urban, environmental and socio-economic Italian context. The housing crisis that our country is going through is outlined, stressing the critical issues related to the different types of dwellings and the resulting quality of t...
INTRODUZIONE La crisi economica e finanziaria, che tutt'ora avvolge l'Europa, ha avuto come principale conseguenza, per alcuni stati membri, la forte contrazione della spesa pubblica. In Italia questa contrazione è andata a incidere in modo indifferenziato su diversi ambiti delle politiche di welfare, e in particolar modo si è concretizzata in una...
Nowadays, lack of affordable housing in Italy heightens emergency conditions of homelessness more than in the past. First of all, housing supply is very poor in terms of quantity and the present small amount, mainly designed for society of 70s, is inadequate to meet current needs. Secondly, public housing is not able to match today's requirements o...
Gli autori propongono l'articolazione di un quadro strategico di policy, per intensificare l’efficacia delle azioni ed implementare il livello di resilienza dell’ambiente urbano, dinanzi al fenomeno delle dismissioni, potenzialmente destabilizzante per gli equilibri economici, sociali e, non meno, per quelli pianificatori.
Sulla base delle criticità rilevate sono stati ela-borati i tre differenti scenari che non costitu-iscono soluzioni progettuali definite, ma che, con modalità e finalità distinte tra loro, tendo-no a mettere in luce le potenzialità del patri-monio di edilizia residenziale pubblica della città di Roma di proprietà dell' ATER. Gli scenari propongono,...
Questo scenario fotografa l'inadeguatezza del quadro normativo contemporaneo che impedisce all'ATER di assolvere la propria funzione sociale di fornire alloggi al maggior numero di utenti delle fasce deboli. Le simulazioni numeriche effettuate danno conto dell'esito di un ipotetico rilascio degli alloggi assegna-ti ad inquilini non più aventi dirit...
