MESSA A PUNTO DI UN SISTEMA SOLARE FOTOVOLTAICO-TERMICO PVT A BASSA CONCENTRAZIONE

Lo sfruttamento intensivo della risorsa solare può contribuire sensibilmente alla riduzione delle emissioni di gas clima alteranti. La crescita e la diffusione di impianti solari dipendono anche dalla capacità dell'industria di costruire e mettere in commercio collettori solari di nuova concezione ad alta efficienza energetica. Il presente lavoro descrive la realizzazione e la messa a punto di un circuito di prove sperimentali, presso il Dipartimento di Ricerche Energetiche ed Ambientali dell'Università di Palermo, relativo ad un impianto solare costituito da collettori solari parabolici lineari a debole concentrazione caratterizzati dal fatto di riunire in un’unica tecnologia chiamata CPVT…

Integrated approach to the assessment of waste management systems within the SEA framework

This paper addresses the problem of evaluating the environmental performances of Urban Waste Systems. Specifically, the paper refers to the crucial problem of environmentally analysing the Urban Waste System Management Process. The application of the Dashboard of Sustainability has been deliberately suggested. The method has been selected because of its intrinsic simplicity and because it can provide the simultaneous evaluation of indicators which refer to different fields, such as the Environment, Economics and Quality in Institutional Services. The method has been applied to the city of Palermo. The results obtained have been compared to a couple of ideal scenarios.

Life cycle assessment of a solar thermal collector: sensitivity analysis, energy and environmental balances

Abstract Starting from the results of a life cycle assessment of solar thermal collector for sanitary warm water, an energy balance between the employed energy during the collector life cycle and the energy saved thanks to the collector use has been investigated. A sensitivity analysis for estimating the effects of the chosen methods and data on the outcome of the study was carried out. Uncertainties due to the eco-profile of input materials and the initial assumptions have been analysed. Since the study is concerned with a renewable energy system, attention has been focused on the energy indexes and in particular the “global energy consumption”. Following the principles of Kyoto Protocol, …

New exergy criterion in the “multi-criteria” context: a life cycle assessment of two plaster products

This paper deals with the exergy analysis (EXA) of plaster materials and ranks the environmental burdens due to the production of such materials. The calculation of the exergy loss during the whole examined process represents a relevant index, looking at the technology improvement of a process, as a suitable tool in aid of the trade-off of alternative materials in the decision making. A life cycle inventory is performed for building plaster products and the matrix method is used. The authors extend the application of EXA to life cycle assessment, conducting an exergetic life cycle assessment, and propose an exergetic index in the framework of multi-criteria decision making. An exergy balanc…

Application of Environmental Management Systems (EMS) to Natural Parks and reserves

Natural parks and reserves have to face problems concerning the conservation of their natural resources. Citizens and firms often perceive the institution of new protected areas more as a bind or a restriction to their activities than an added value of the territory. Following the principles of sustainable development, it is necessary to integrate the environmental protection with the needs of neighbouring urban areas and production sites. The implementation of an Environmental Management System (EMS) according to international standards (ISO 14001, EMAS) can support the Park administration in their complex management activities. This paper analysed the criticisms related to the application…

POEMS: A Case Study of an Italian Wine-Producing Firm

Over the last decade, researchers paid much attention to concepts such as Design for Environment, Extended Producer Responsibility, Responsible Chain Management, and Eco-design. Many management tools and standards (such as EMAS, ISO 14001, LCA, EPD, Ecolabel) have been developed to support companies in the evaluation and management of their environmental performance and to pursue continual environmental improvement. The more recent development of the aforesaid fields looks at interorganizational environmental management. Such an approach can complement the more traditional intraorganizational corporate environmental management approaches and tools. A typical example of this new trend is the…

Life cycle assessment of a solar thermal collector

Abstract The renewable energy sources are often presented as ‘clean’ sources, not considering the environmental impacts related to their manufacture. The production of the renewable plants, like every production process, entails a consumption of energy and raw materials as well as the release of pollutants. Furthermore, the impacts related to some life cycle phases (as maintenance or installation) are sometimes neglected or not adequately investigated. The energy and the environmental performances of one of the most common renewable technologies have been studied: the solar thermal collector for sanitary warm water demand. A life cycle assessment (LCA) has been performed following the inter…

Is the transfer function method reliable in a European building context? A theoretical analysis and a case study in the South of Italy

Abstract The available tools for dynamic simulation of the buildings thermal behaviour are manifold, and the most modern ones, known as TRNSYS, are founded upon the use of the Z-transform (ZT) set also called transfer function method (TFM). The transfer function method (TFM), recommended by American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), is one of the most modern tools available to solve heat transfer problems in building envelopes and environments. TFM utilises Z-transforms to solve the equation system that describes the heat transfer in a multi-layered wall. Due to an analogy with an electric circuit, it is possible to write the equation system in a mat…

A web-based autonomous weather monitoring system of the town of Palermo and its utilization for temperature nowcasting

Weather data are crucial to correctly design buildings and their heating and cooling systems and to assess their energy performances. In the intensely urbanized towns the effect of climatic parameters is further emphasized by the "urban heat island" phenomenon, known as the increase in the air temperature of urban areas, compared to the conditions measured in the extra-urban areas. The analysis of the heat island needs detailed local climate data which can be collected only by a dedicated weather monitoring system. The Department of Energy and Environmental Researches of the University of Palermo has built up a weather monitoring system that works 24 hours per day and makes data available i…

Eco-sustainable energy and environmental strategies in design for recycling: the software “ENDLESS”

Abstract This paper describes a model, named “ENDLESS”, useful to address the design process towards more eco-compatible solutions. In particular, this tool can support the designer in the choice of the product with an higher recyclability potential from a set of different alternatives. The model takes into consideration a Multi-Attribute Decision-Making method and allows calculating a “Global Recycling Index” (GRI) starting from a set of energy, environmental, technical and economic indicators. A weight is assigned to each parameter following the experience of the designer; a sensitivity analysis is then performed to state how the different assumptions can affect the final results. The mod…

Life cycle assessment of building materials: A comparison by electre methodology

There is a growing awareness that in selection of building materials the designer must also consider environmnental impacts, either in global and local scale. Unfortunately, design community has an inadequate knowledge about the factors that affects environmental consequences of producing and operating buidings. To increase understanding on selection criteria and comparison of building alternatives in an “energy and environmental point of view”, is a significant goal for restraining gloabl enevironmental degradation. An interesting approach for assessing comparable products is the so called “multicriteria decision making”, but there is much debate about aggregation of criteria and weights a…

Transferability to LDC of Some European standards concerning the environmental certification of products and services

Goal and Scope. Western developed countries (DC) are currently involved in an important process of releasing new rules and standards devoted to the environmental certifications of urban systems, in order of accomplishing the requirements established by the international protocols (Kyoto, among them), aimed at the reduction of greenhouse gases emitted in the atmosphere and at the limitation of the environmental impact as well. Within this frame, the European Union is giving a rising importance to the so-called 'Integrated Product Policy' (IPP), that is an integrated approach of the environmental policy, aiming to an improvement of the environmental performance of products and services during…

Single thermal zone balance solved by Transfer Function Method

We present an algorithm that uses the Z-transform operator to face the problem of heat transmission in a single thermal zone composed by multilayered walls. The method is very flexible and could be adopted to calculate the transfer function coefficients able to simulate the thermal behaviour of a room in free floating. Knowing the transfer function coefficients, it is possible to simulate the dynamic profile of each inner surfaces temperature and furthermore of the inner air temperature. The proposed algorithm is fully described granting maximum clarity. The explicitness of all steps of the calculus make possible the definition of a method that is able to vary all of the calculus parameters…

A decision support system to compare different strategies for achieving the Italian Kyoto Protocol commitment

Abstract: In order to meet the Italian Kyoto Protocol commitment, in 2002 the Interministerial Committee for Economic Planning (CIPE) approved the national allocation plan for the reduction of Greenhouse Gases (GHGs), envisioning various alternative scenarios. In this paper an extended impact assessment of the plan is accomplished and some further options are conceived and analysed in order to find an optimal trade-off among the different economic, environmental and social items at stake. After the selection of a set of independent indicators, nine different scenarios for the GHG reductions were evaluated and they were sorted according to the principles of the multicriteria analysis. The re…
