Energy Retrofit. A Case Study—Santi Romano Dormitory on the Palermo University

2021

Electrical and thermal consumption related to buildings, whether civil, commercial, public, or of any other kind, is very much in focus today. With today’s targets for energy savings, reduction of consumption, and environmental impact, it is necessary to carry out energy retrofits to modernize installations and their management. The realization of an effective improvement requires a careful analysis of the case study because each category of building has different requirements such as different load profiles and different installations and needs. This was carried out by studying the electrical and thermal load profiles. A good initial energy audit can provide the retrofit solutions capable …

Six-years-long effects of the Italian policies for photovoltaics on the pay-back period of grid-connected PV systems installed in urban contexts

2017

Abstract In this study the discounted pay-back (DPB) period of rooftop photovoltaic (PV) systems installed in urban contexts was investigated during the course of time with the aim of evaluating the effects of the different supporting policies enacted by the Italian government. The profitability of the investment in three Italian cities was observed from June 2010 to May 2016 by means of an exhaustive economic analysis based on the study of the variation of the costs and benefits during the lifetime of the investment. The analysis considered the disbursements for the PV system devices, maintenance and management, insurance, and wear of PV panels and inverters. Other significant parameters, …

FROM SCAN-TO-BIM TO HERITAGE BUILDING INFORMATION MODELLING FOR AN ANCIENT ARAB-NORMAN CHURCH

2022

Abstract. One of the most significant issues in Cultural Heritage is the management of ancient buildings to monitor their state of conservation or to plan actions in their maintenance; this issue can be now approached thanks to the use of the Scan-to-BIM process. This method allows the creation of parametric models into a BIM environment, which are capable of enhancing the geometrical representation of building elements and integrating different types of data.This paper shows the results of the research activities carried out by the Department of Engineering at University of Palermo (Italy) on applying the Scan-to-BIM approach to the survey and the modelling of an ancient Arab-Norman church…

Analisi dei dati dell’edificio esistente, 2. Redesign dell’edificio esistente, 3. Embodied energy dell’edificio esistente. 4. Partecipazione a gruppi di lavoro internazionali in seno alla task 40 dell’IEA. Gli indicatori sviluppati nel corso dei lavori…

The emergence of lean construction in the Norwegian AEC industry

2021

Lean construction has inspired the AEC industry globally over the last decades, and this manifests within a wide array of contexts. The purpose of this paper is to provide a narrative-based qualitative analysis of the emergence and impact of Lean construction on a national level, notably in the Norwegian AEC industry. The analysis is based on the concept of paradigm shift and on empirical knowledge in the form of narratives. The narratives of practitioners and researchers provide deep insights into how Lean Construction has inspired the Norwegian AEC industry and academia, respectively. The reflections indicate that the introduction of the Lean construction principles and tools in the Norwe…

Adaptive use patterns of secondary school classroom environments

2006

Purpose – The purpose of this research is to investigate how secondary school teachers adaptively make use of the classroom learning environment. The approach illustrates the intimate relationship between teaching style, learning style and the adaptive use of space as well as the preferences for different learning environments.Design/methodology/approach – A multi method study approach was used to carry out the research. Two main methods were used in the study. In the first method, trainee teachers recorded spatial observations (mapping). Maps of the chemistry classrooms were produced. The observers marked all fixed, semi‐fixed and flexible elements in the classroom space. The second method…

Comparative LCA of renovation of buildings towards the nearly Zero Energy Building

2018

The building sector is one of the key sectors to achieve the 20/20/20 targets of the EU as there is the potential to lead to significant energy savings reducing the EU’s total energy consumption by 5-6% and lowering CO2 emissions by 5%. One powerful mechanism to apply principle and criteria of nearly zero-energy buildings (nZEB). This work, done in the framework of the agreement between the Italian Ministry of Economic development and ENEA on the “Research of electric system” (Ricerca di Sistema Elettrico), has the aim to evaluate the environmental impacts of the technological improvements needed for enhancing the performances of an average building to a nZEB (or at least in the direction o…

Redescribing the Nation : Anti-Semitism as a tool of nation-building in the Hungarian Numerus Clausus debates, 1920-1928

2018

Abstract Boosting national spirit through projection of otherness is not a new phenomenon, at least in authoritarian regimes. Yet the role of anti-Semitism in the Numerus Clausus debates in the Hungarian parliament in 1920 and 1928 is worth deeper analysis, as it bore a peculiar role in the Hungarian interwar counterrevolutionary nation-building. The Numerus Clausus law of 1920 set ethnic quotas to university enrolment; the explicit argument for this was countering the Jewish ‘over-representation’ in Hungarian society. However, in 1928 the law was amended, abolishing (in principle) the said quotas; this time the arguments favoured national consolidation, where segregation was to be moderate…

Palais et fisc à l'époque carolingienne: Attigny

1982

Domaine rural acquis par Clovis II en 651, Attigny fut une résidence du maire du palais Pépin à partir de 749. Devenu un palais avec l'avènement des Carolingiens, il cessa d'être fréquenté après 931. La fonction essentielle de ce palais découle de sa situation géographique située à proximité de la voie romaine Reims-Trêves, la localité constituait une étape commode entre est et ouest du royaume franc, puis entre les royaumes de Francie occidentale et de Lotharingie. Le fisc d'Attigny, mentionné pour la première fois en 877, peut être connu par l'analyse de trois diplômes, dont deux très postérieurs à la période carolingienne. Il englobait au début du Xe siècle au moins trois mille cinq cent…
