Cost-efficiency assessments of marine monitoring methods lack rigor—a systematic mapping of literature and an end-user view on optimal cost-efficienc…
2021
Global deterioration of marine ecosystems, together with increasing pressure to use them, has created a demand for new, more efficient and cost-efficient monitoring tools that enable assessing changes in the status of marine ecosystems. However, demonstrating the cost-efficiency of a monitoring method is not straightforward as there are no generally applicable guidelines. Our study provides a systematic literature mapping of methods and criteria that have been proposed or used since the year 2000 to evaluate the cost-efficiency of marine monitoring methods. We aimed to investigate these methods but discovered that examples of actual cost-efficiency assessments in literature were rare, contr…
Neutralidad y honorabilidad del árbitro: : De la ética a la diligencia
2021
One of the main principles of arbitration is that the arbitral tribunal must be independent, impartial, neutral and diligent in carrying out its duties throughout the arbitration proceedings. However, the sophistication and complexity of arbitration as an extra-judicial dispute resolution procedure can undermine confidence in the efficiency of the system. In this regard, the professional (arbitral) ethics and the honourability of the arbitrator are of major importance. This article aims to highlight the importance of the neutrality of the arbitrator, the integrity of the arbitration and the reputation of this procedure
A laboratory setup for the evaluation of the effects of BACS and TBM systems on lighting
2015
The paper focuses on the evaluation of the impact of Building Automation Control Systems (BACS) and Technical Building Management (TBM) systems on the performance of the lighting system in a residential building. In particular, this work shows a laboratory setup, installed at the DEIM of the University of Palermo, for simulating a typical apartment. The paper describes the laboratory, the lighting system and the BAC system installed and the test facility for evaluating the electricity consumption in presence and in absence of automation. The laboratory has been built within a research project funded by the Italian Minister of University and Research in the framework of the PON Smart Cities …
Acciones para mejorar la eficiencia energética en los edificios en Europa: estado del arte sobre los standards técnicos
2022
The paper is aimed at reviewing the state of the art of the European technical normative implementation during the last decades concerning the building energy efficiency. Indeed, it is well acknowledged that the present building stock is largely obsolete and inefficient: in the European context alone, around 75% of the buildings is not energy efficient and most are expected to be in use until 2050. Consequently, buildings require not only a general rehabilitation, to extend, or even avoid, its end-of-life time, but also a complete afterthought of their energy performance. That is extremely urgent to improve the overall sustainability of the construction sector that, alone, is one of the mai…
Characterization of cooling loads in the wine industry and novel seasonal indicator for reliable assessment of energy saving through retrofit of chil…
2020
Abstract The food sector is a major consumer of energy and growing efforts are being made in the search for solutions that will guarantee the efficient and sustainable use of energy resources. Among the different sectors, wineries are attracting particular interest due to the continuous growth of the global market and production. Surveys conducted in the winemaking sector have highlighted the importance of performing accurate energy audits and have identified the installation of efficient refrigeration systems as a promising solution in a variety of cases. Unfortunately, the savings achievable by efficient cooling technologies are often estimated using simplified approaches which do not tak…
A Case-Study of Green Roof Monitoring: The Building of Council for Agricultural Research and Economics in Bagheria, (Italy)
2018
The energy saving in building goes on as an important challenge in the policy of Developed Countries. While the issue of energy building efficiency in heating season has deeply been investigated for a long time, the issue of energy building efficiency in cooling season is relatively recent. Moreover, considering the increase of electric consumption for air-conditioning in summer, mainly due to the growing quality of life, the research of technologies for reducing energy building consumption during this season becomes essential. The green roof represents a technology useful to reduce the energy consumption during the cooling season. In this work the authors report the results of a monitoring…
The urban and environmental building code as implementation tool
2014
The frame within which the work is placed refers to the actions necessary to achieve the objectives of the coverage of the consumption of energy from renewable sources compared to the gross final consumption, posed to Regions by 2020, and that can be implemented through various actions involving local gov-ernments including the revision of the Building Regulations municipalities in a sustainable view. Theseactions are increasingly being recognized as energy plan-ning tools for the territories where administrations have committed to the Euro-pean project Covenant of Mayors. The discussion shows how the adoption by the Regions of Guidelines for sustainable Municipal Building Regulations can b…
Efficiency of Telematics Systems in Management of Operational Activities in Road Transport Enterprises
2020
Implemented in road transport enterprises (RTEs) on a large scale, telematics systems are dedicated both to the particular aspects of their operation and to the integrated fields of the total operational functioning of such entities. Hence, a research problem can be defined as the identification of their efficiency levels in the context of operational activities undertaken by RTEs (including more holistic effects, e.g., lowering fuel/energy consumption and negative environmental impacts). Current research studies refer to the efficiency of some particular modules, but there have not been any publications focused on describing the efficiency of telematics systems in a more integrated (holist…
Analysis a DSP Implementation and Experimental Validation of a Loss Minimization Algorithm Applied to Permanent Magnet Synchronous Motor Drives
2004
In this paper a new loss minimization control algorithm for inverter-fed permanent-magnet synchronous motors (PMSM), which allows to reduce the power losses of the electric drive without penalty on its dynamic performances, is analyzed, experimentally realized and validated. In particular, after a brief recall of two loss minimization control strategies (the "search control" and the "loss-model control"), both a modified dynamic model of the PMSM, which takes into account the iron losses, and a "loss-model" control strategy, are treated. Experimental tests on a specific PMSM drive employing the proposed loss minimization algorithm were performed aiming to validate the actual implementation.…
Life Cycle Assessment of a compact Desiccant Evaporative Cooling system: The case study of the “Freescoo”
2016
Abstract The paper aims at exploring the performances of a compact Desiccant Evaporative Cooling system called “Freescoo” (Free Solar Cooling) in comparison to standard conventional technologies. The Freescoo – that aims at applications in the residential sector and in small office buildings and includes a photovoltaic–thermal system – is analyzed, its monitored performance discussed and reported: under cooling conditions an Energy Efficiency Ratio of 12.8 is calculated, that reaches 50.7 if also photovoltaic generation is considered. To assess the performance of the proposed system a Life Cycle Assessment study was performed to investigate the system covering all its life, from the product…
