Deep Energy-Zero Emission Renovation attraverso la circolarità delle risorse idriche nei Distretti Urbani
No full textLa neutralità climatica entro il 2050 è un obiettivo prioritario e ridurre le emissioni di gas serra, aumentare l’efficienza energetica, e migliorare i processi di circolarità delle risorse sono gli imperativi che ricorrono negli strumenti normativi ed economici attuali. La presente Tesi, a partire dal tema centrale della mitigazione delle cause del cambiamento climatico, si pone al centro delle linee di Ricerca volte alla neutralità climatica focalizzandosi, attraverso l’applicazione dei principi della circular economy, quale presupposto alla green economy, sulla Deep Energy-Zero Emission Renovation attraverso il miglioramento dei processi di circolarità delle risorse idriche nella loro integrazione con quelle energetiche e sull’ottimizzazione della gestione all’interno dei Distretti Urbani, per misurarne la capacità effettiva di contribuire a ridurre le emissioni di gas serra in fase di uso e distribuzione da rete idrica. A partire da una sistematizzazione e da una sintesi delle informazioni acquisite ed elaborate durante tutto l’iter di Ricerca, la parte conclusiva della Tesi di Dottorato porta a delineare la fase di output divulgativo-scientifico dei risultati della Ricerca: il tool di calcolo e le linee guida, a servizio degli utenti finali e degli esperti del settore, per operare nei Distretti Urbani collocati in zone che subiscono un impatto di media criticità sui parametri climatici, al fine di migliorare il processo di circolarità della risorsa idrica e di ridurne in termini quantitativi le emissioni climalteranti correlate, con interventi che coinvolgano la dimensione dell’acqua, del suolo e dell’energia, in un’ottica sistemica di Decarbonizzazione del patrimonio edilizio esistente e dei Distretti Urbani
Evoluzione urbana e sociale dell’edilizia popolareIl caso INCIS Decima e UNRRA Casas San Basilio a Roma
Get PDFThe neighbourhoods of economic and social housing, conceived as a place of evolutionary progress of society have become today often places of abandonment, social and economic degradation, many of them downgraded to ‘dormitory districts’. The need to catalogue, census the problems encountered by the inhabitants of these areas responds to the request for housing policies aimed at the redevelopment of these spaces, the energy upgrading of buildings, infrastructure and open spaces. These aspects are associated with current issues in the national, European and global landscape; according to the 2019 Global Status Report for Buildings and Construction, produced by the Global Alliance for Buildings and Construction ‘GlobalABC’, the construction sector is responsible for 36% of final energy consumption and 39% of total carbon dioxide emissions worldwide, 11% of which come from the production of construction materials such as steel, glass and cement. These considerations provide an opportunity to intervene on the existing building stock with urban requalification projects. This text aims analysing two public housing districts which differ in their historical evolution, typology, structure and economic-social conformation: the INCIS District in Decima (L. Moretti, A. Libera, L. Cafiero, 1957-1965), located south of the EUR District, born from a new urban vision of the concept of residence and the UNRRA Casas San Basilio District (M. Fiorentino, 1951-1955), at km 12 of via Tiburtina, built in implementation of the financing program deriving from American aid to European countries. The regional and national legislative panorama, such as the Ecobonus 110% and the Three-Year Plan for Public Housing of the Lazio Region, provide valuable incentives in the field of regeneration, recovery and reduction of energy consumption of existing building envelopes
Refurbishment and electrification in the hotel sector: four hotels in the historic centre of Rome
Get PDFAccording to the European Renovation Wave, the European building stock is obsolete and changes very slowly: more than 220 million housing units and 85-95% of the existing buildings will still be in use in 2050 and are absolutely not energy efficient. To cut emissions by 55% by 2030, the EU should reduce greenhouse gas emissions from buildings by 60%, their final energy consumption by 14% and energy consumption for heating and cooling by 18%. It is therefore urgent for the EU to focus on making buildings more energy efficient, less carbon intensive throughout their life cycle and more sustainable. From this framework comes the need for an adaptation not only of residential buildings but also of hotel facilities, which, on a national scale, make up about 45% of the accommodation facilities. In particular, the offer of accommodation facilities must be constantly adequate and the structures must be upgraded so that they always remain usable and comply with current regulations from the accessibility, seismic-structural and energy point of view. In this research, four hotels located in the historic centre of Rome have been analysed as case studies. Starting from an analysis of the current state, a series of interventions on the building envelope and systems have been studied, evaluating energy savings and the reduction of polluting emissions. With regard to the systems, the total electrification of the heating and domestic hot water preparation systems has been hypothesised, with the introduction of storage systems, also in view of participation in Demand Response programs
Criticity Mapping and Integration Quantity Evaluation of Solar Installations in Mediterranean Heritage Territories
No full textThe study aims at evaluating the applicability of the LESO-Quality-Sensitivity-Visibility (QSV) method for the assessment of active solar installations on Mediterranean architectural heritage. To this purpose, 10 significative case studies with the integration of photovoltaic and solar thermal system have been evaluated using this method. This assessment is compared with the results of expert enquires realized on the same case studies by the Heritage Authorities, to define potentialities, limits, and possible modifications. Finally, the integration of the two methodologies with international policies allows the definition of an articulated set of formal characteristics that solar systems in heritage contexts should have. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024
Active solar heritage architecture: lessons learned from international experiences

The case studies are assessed from a quantitative and qualitative point of view, verifying the presence of common trends, patterns, and key success factors and identifying emerging technologies, prototypes, and solutions. Their sensitivities, criticalities, and potentials are discussed and compared to identify emerging technologies, prototypes, and solutions. In the end, five design projects are presented and illustrated in detail, considering their specificities, positive and negative aspects, and lessons learned from direct interaction with the designers
Widespread Industrial Heritage in Fragile Sites as a Resilient Resource: A Life Cycle and NetZero Approach to Regeneration
No full textThis chapter examines a research area focused on experimenting with adaptive reuse strategies of the industrial and disused heritage widespread in fragile contexts. Experimentation, through environmental technological design with a life- cycle approach, aims to de ne interventions and integrations in architectural and landscape heritage compatible with the updated functional, construction, economic- productive and energy-environmental needs, in a condition of continuous variability also determined by the multiple actions of climatic, natural and anthropic risks. The keywords that emerge refer to the founding themes of the research centred on little- known, widespread and small- and medium-sized architectural heritage, with lim- ited material and functional interest, serial, often dif cult to be recognized, but whose value lies in the historical, technological, social and scienti c testimony of the factory, of the machinery and of the infrastructures, that can be considered as the result of experiments and innovations which have contributed to determine the char- acteristics of the contemporary territory. The research questions concern the strate- gies and tools to integrate and balance the demands of transformation with those of protection, with adaptive reuse actions to support the transition towards a historical heritage that is “ecologically resilient” according to a NetZero approach (zero soil- energy-CO2-waste) aiming at the adaptation and mitigation and at the same time at the climate neutrality of these complex urban or peri-urban systems. Strategies and principles declined in concrete interventions set in complex, sensitive and fragile scenarios that host a widespread industrial heritage throughout Italy, as in the case study of the Ex SAI in Passignano sul Trasimeno
Historical analysis and refurbishment proposal of the “Red schools” in Viterbo
Get PDFTo hinder climate change, EU legislation requires that by 2020 each European state achieves the objectives set by the 2020 Climate and Energy Package. Particular attention is paid not only to new constructed buildings, the so-called Near Zero Energy Buildings, but also to the existing building stock: in Italy in fact, in addition to the National Action Plan to increase the NZEB buildings (PANZEB), the Strategy for Energy Renewal of the National Real Estate Park (STERPIN) is planned. The aim of the thesis work is a primary school built in 1938 within the historical centre of Viterbo. The work touched on three different areas of design: the design of the internal and external spaces, annexed to the school building, finding solutions for a flexible and functional distribution in line with the theories of modern pedagogy, moving from a school of homologation to a school of diversity enhancement.
This was joined by a study concerning the original elevations and constructive features, bearers of historical and aesthetic values, which resulted in the proposal for conservative restoration of the Terranova plaster and the original iron-window profiles.
Finally, attention was paid to energy upgrading and efficiency, in line with regulatory provisions.
The interventions did not only concern the building envelope (through a thermal upgrading of the original iron-windows, the insulation of the flat roof and the indoor thermal coat of the perimeter walls), but also the system (through the replacement of the boiler with a heat pump, integrated with the photovoltaic system placed on the roof, the inclusion of thermostatic valves and lighting design with the replacement of fluorescent lamps with LED ones)
Integrating Technological Environmental Design and Energy Interventions in the Residential Building Stock. The Pilot Case of the Small Island Procida
Get PDFThe next decade will see severe environmental and technological risks, pushing our adaptive capacity to its limits. The EPBD Case Green directive, to counter this phenomenon, emphasizes accelerating building renovations, reducing GHG emissions and energy consumption, and promoting renewable energy installations. Additionally, it calls for deadlines to phase out fossil fuels and mandates solar system installations. This research provides a comprehensive perspective on the opportunities for and challenges of incorporating renewable energy into the built environment. It focuses on the 2961 residential buildings on Procida, a small island located south of Italy, to efficiently utilize energy resources and lay the groundwork for sustainability. Beginning with an analysis of the territorial, urban, historical–conservation, structural, and geological context, in addition to environmental assessments, the research develops a classification and archetypalization system using in-house software. This system aggregates data on the island’s residential buildings, analyzes their current state, and formulates various intervention scenarios. These scenarios demonstrate how integrating technological–environmental design interventions, such as upgrading the building envelope and enhancing bioclimatic behavior, with energy retrofitting measures, such as replacing mechanical systems and installing solar panels, can improve the overall performance of the existing building stock and achieve energy self-sufficiency
Halving of consumption and energy efficiency of the “Mario Pagano” National boarding school in Campobasso
Get PDFIn the national context, Italy with the Integrated National Plan for Energy and Climate (PNIEC) intends to achieve an indicative target of reducing consumption by 2030 equal to 43% of primary energy and 39.7% of final energy compared to the reference scenario of 2007 while with the National Recovery and Resilience Plan (PNRR), the ecological transition will have to be the basis of the new development model on a global scale. To start it up, it will be necessary to drastically reduce emissions of climate-altering gases in line with the objectives of the European Green Deal. Secondly, it will be necessary to improve the energy efficiency of production chains, civil settlements and public buildings and the quality of air in urban centres and water. In light of these ambitious objectives, particular attention is paid to existing buildings: this research has been focused on the is the National Boarding School “Mario Pagano”, an 8,700 m2 school built in 1899, located in the historical centre of Campobasso (Molise).
The effects of the intervention proposals have been simulated in order to evaluate energy savings and the reduction of CO2 emissions. The research is also supported by an economic evaluation that prove the economic sustainability within a period of about 15 years
