Urban Heat Island Effect on the Energy Consumption of Institutional Buildings in Rome

The urban heat island (UHI) effect is constantly increasing the energy consumption of buildings, especially in summer periods. The energy gap between the estimated energy performance - often simulated without considering UHI - and the real operational consumption is especially relevant for institutional buildings, where the cooling needs are in general higher than in other kind of buildings, due to more internal gains (people, appliances) and different architectural design (more transparent façades and light walls). This paper presents a calculation of the energy penalty due to UHI in two institutional buildings in Rome. Urban Weather Generator (UWG) is used to generate a modified weather file, taking into account the UHI phenomenon. Then, two building performance simulations are done for each case: the first simulation uses a standard weather file and the second uses the modified one. Results shows how is it necessary to re-develop mitigation strategies and a new energy retrofit approach, in order to include urbanization ad UHI effect, especially in this kind of buildings, characterized by very poor conditions of comfort during summer, taking into account users and occupant-driven demand

Establishing a core outcome set for peritoneal dialysis : report of the SONG-PD (standardized outcomes in nephrology-peritoneal dialysis) consensus workshop

Outcomes reported in randomized controlled trials in peritoneal dialysis (PD) are diverse, are measured inconsistently, and may not be important to patients, families, and clinicians. The Standardized Outcomes in Nephrology-Peritoneal Dialysis (SONG-PD) initiative aims to establish a core outcome set for trials in PD based on the shared priorities of all stakeholders. We convened an international SONG-PD stakeholder consensus workshop in May 2018 in Vancouver, Canada. Nineteen patients/caregivers and 51 health professionals attended. Participants discussed core outcome domains and implementation in trials in PD. Four themes relating to the formation of core outcome domains were identified: life participation as a main goal of PD, impact of fatigue, empowerment for preparation and planning, and separation of contributing factors from core factors. Considerations for implementation were identified: standardizing patient-reported outcomes, requiring a validated and feasible measure, simplicity of binary outcomes, responsiveness to interventions, and using positive terminology. All stakeholders supported inclusion of PD-related infection, cardiovascular disease, mortality, technique survival, and life participation as the core outcome domains for PD

Riqualificazione energetica nel settore terziario Casi di studio e strategie d'intervento.

A livello Europeo, il 40 % dei consumi elettrici viene dal settore terziario. Lo stato dell’arte sul settore terziario in Italia è privo di approfondimenti dettagliati e studi specifici che sappiano descriverne l’attuale consistenza e stato conservazione, con conseguente valutazione del potere energivoro dello stesso e del potenziale di risparmio ottenibile da strategie d’azioni mirate sul patrimonio esistente.Gli edifici strategici ed in particolare gli edifici strategici pubblici, inoltre, alla luce della congiuntura economica attuale e delle nuove urgenze ambientali dell'UE, devono ricoprire un ruolo esemplare, nell'avviamento di un programma di riqualificazione energetica, che possa costituire un volano per l'innovazione di prodotto e di processo.studio in via di sviluppo si pone l'obiettivo di fornire strumenti operativi di intervento sul parco edilizio oggetto d'indagine, definendo caratteristiche di consistenza e di utilizzo effettivo degli immobili, il regime di funzionamento e di consumo e, infine, le linee di intervento da seguire

Deep Renovation: Key Action For Active Protection Of Modern Heritage. The Case Of Architecture For The Service Sector

Energy renovation is instrumental for reaching the EU 2020 goals and smart districts are integral parts for the development of Smart Cities in the next future. At building scale, every structure runs differently and energy consumption profiles depends not only on climatic locations and technological quality of buildings, but also on occupancy levels and different types of public utility buildings (school, healthcare and homes for the elderly, office, university). A new smart regeneration approach will represent the central focus beyond a simple technological concept of Smart Building, where the buildings should be seen as part of a larger system of energy networks and whose diffusion within the city could be linked with the concept of urban energy network and physical “nodes”. Currently good practices and projects aims to promote the adoption of the key technology and to identify and remove barriers to deployment, still today approaches to record non-residential assets in a comparable structure have not been successfully implemented yet and data are fairly poor. An integrated approach is proficient to reveal the performance of the innovation, its technical requirement, as well as prerequisite required in terms of existing infrastructures, technical expertise, regulatory requirements and financial costs involved. An ongoing research from the PDTA Dept. is promoting a set of exemplary of public utility buildings and a portfolio of material, industrialized systems, smart and energy equipment solutions to be used in refurbishment projects, in order to stimulate a whole vision of the smart efficient buildings and different scenarios according the boundaries of a smart district level in Rome Municipality

Riqualificazione tecnologica integrata come strumento di valorizzazione e di tutela attiva del patrimonio città consolidata. Deep renovation as tool for development and active protection of the consolidated city heritage

Il contributo propone la sintesi di diverse attività di ricerca pluriennali realizzate con il sostegno della Sapienza e la collaborazione di vari Enti territoriali e alcuni privati sulla riqualificazione integrata dell’architettura per il settore terziario. Gli esiti delle ricerche condotte pongono le basi per la costruzione di una metodologia replicabile di analisi e valutazione preliminare utile a indirizzare gli interventi di riqualificazione profonda del patrimonio per il terziario. Nelle varie fasi della ricerca svolta sono stati selezionati alcuni casi di studio sul territorio nazionale, affrontati come campo di verifica teorica degli assunti della ricerca, e come verifica effettiva di opzioni progettuali di riqualificazione integrata, di edifici prevalentemente destinati al direzionale, alla formazione e alla ricerca.This paper is the synthesis of multi-year research activities carried out with the support of Sapienza University in collaboration with some local authorities and private entities on integrated refurbishment planning of tertiary buildings. The outcomes of research are aimed at the construction of a replicable methodology for the preliminary analysis and evaluations useful for deep renovation of tertiary building heritage. During the various steps of the study, there were selected pilot buildings throughout the country, addressed to validate theorical assumptions of research, and to check actual strategies of integrated refurbishment of buildings mainly used for directional, educational and research activities
