Multi-Objective Building Envelope Optimization through a Life Cycle Assessment Approach
2019
This work describes a methodology for the identification of the optimal features for the envelope of a residential building. The optimization process allows minimizing operating energy consumption, investment costs and life cycle energy and environmental embodied impacts. A dynamic model for the estimation of building energy consumption during its use phase has been employed, while literature data were adopted for embodied energy and global warming potential impacts. The considered variables refer to the envelope of the building, i.e. external walls and roof insulation and external walls thermal mass. The model was obtained combining EnergyPlus building energy simulator and MOBO, a versatil…
Green Roofs’ End of Life: A Literature Review
2023
Green roofs are increasingly being used in urban settings because of the many benefits they are capable of providing. Because of their widespread use, the issue of how to conduct proper disposal of green roofs once they have reached their end of life is beginning to be raised. The present study is a review of the scientific literature published between 2007 and 2022. Specifically, the contribution of this review study is to clarify whether a waste scenario exists and if so, identify the methodological frameworks and/or criteria used in green roof-related studies to establish the end-of-life scenario of a given green roof, which will then be used to analyze its environmental and economic per…
Green roofs for smart cities: experimental determination of the “fractional vegetation coverage” of six vegetated species
2015
Towards a de-carbonization of European countries, green roofs are becoming popular, due not only to aesthetic reasons but also to energy and environmental issues. Indeed, especially in summer periods, the building cooling demand might be sensibly cut thanks to such passive components often chosen for planning smart cities. To properly model the energy performances of buildings equipped with these components, a particular attention must be paid to radiative exchanges occurring among soil surface, leaves and outdoor surroundings. These thermal exchanges depend on parameters, like the “fractional vegetation coverage” whose literature data do not seem particularly suitable for the simulation ne…
Role of green coverings in mitigating heat island effects: an analysis of physical models
2013
Worldwide, governments are introducing several rules and standards in the aim of limiting the quantity of primary energy for air conditioning of buildings and supporting the use of renewable source of energy for generating thermal and electric energy to be utilized in buildings such as the European Directive on the Energy Performance of Buildings [1]. Along with these interventions, another important action takes currently place in the building sector, that is the introduction of passive structural components of the envelope, able to reduce the requirements of energy for air conditioning purposes. Among these building components, the so-called green roofs are becoming more and more interest…
Passive components for reducing environmental impacts of buildings:analysis of an experimental green roof
2020
The reduction of the environmental impacts related to the building sector is a matter of outmost importance concerning the sustainable utilization of resources related to human activities. Such sector is in fact responsible for about 40% of both release of pollutants in the atmosphere and energy consumption. When trying to reduce buildings’ environmental impacts, as well as to limit their energy consumption, building envelope passive systems can be used. Amongst these, green roofs have been gaining global attention due to their benefits in terms of resilience and sustainability, in order to mitigate the unfavourable urbanization effects. Research on the green roof has been indeed increasing…

Travisamenti pretori in tema di esonero dalla responsabilità contrattuale tra causalità e vicinanza della prova
2020
La nota censura la pronuncia in commento a causa della scelta di addossare la prova della causalità materiale al creditore anche nell'ambito delle obbligazioni di facere non professionale, con ciò facendo segnare la piena equiparazione sul piano della causalità della responsabilità contrattuale alla responsabilità aquiliana. The note censures the judgment in question due to the choice of placing proof of material causation on the creditor also in the context of the obligations of non-professional facere, thereby marking the full equation in terms of causality of contractual liability with aquilian liability.
Durata e prescrizione nella garanzia per i i vizi della vendita
2020
Il saggio analizza due recenti sentenze della Corte di cassazione in tema di onere della prova e di decorso del termine di prescrizione in materia di azioni edilizie nella vendita. L'analisi tenta di dimostrare che la soluzione di entrambe le questioni dipende dall'esatta qualificazione giuridica del vincolo del venditore come garanzia, intesa come attribuzione di utilità senza cooperazione. Su queste basi è possibile pervenire a conclusioni diverse e più solide rispetto a quelle cui perviene la Corte di cassazione. The essay analyzes two recent judgments of the Court of Cassation regarding the burden of proof and the expiry of the limitation period for the claim in the field of actions aga…
BREVI NOTE SULL'ONERE DELLA PROVA NEL PROCESSO TRIBUTARIO
2019
La regola dell’onere della prova costituisce un pilastro fondamentale in ogni disciplina processuale. Essa si sviluppa in una molteplicita' di principi attraverso i quali il processo persegue la sua funzione, la ricerca della verita'. Nel processo tributario l’applicazione della regola dell’onere della prova non sempre appare ispirata al principio del giusto processo ed al contribuente a volte è richiesto di offrire una prova che va oltre le sue possibilita'.
