  • identification of the environmental impact from the use of different materials in domestic solar hot water systems
    Applied Energy, 2013
    Co-Authors: Georgios Martinopoulos, G Tsilingiridis, N Kyriakis
    Abstract:

    The use of different materials for the same solar system component (collector, water tank, etc.) affects both the efficiency and the amount of Conventional Energy substituted by the system and hence the overall environmental impact of a Domestic Solar Hot Water System (DSHWS). The net environmental gain achieved by the use of DSHWS therefore is influenced, among others, by the materials and techniques used, up to 20% in some cases. In this paper, Life Cycle Analysis (LCA) of a variety of typical, for the Greek market, DSHWS is performed. Their environmental impact, as well as the influence from the use of different materials or/and manufacturing techniques on their impact, is identified. In all cases examined, the environmental impact of the solar systems is significantly lower compared to that of the Energy conserved. As thermal efficiency differs from system to system, their environmental performance is influenced mainly by the Conventional Energy substituted and to a lesser extent by the materials used for their production.

  • life cycle environmental impact of a thermosyphonic domestic solar hot water system in comparison with electrical and gas water heating
    Renewable Energy, 2004
    Co-Authors: G Tsilingiridis, Georgios Martinopoulos, N Kyriakis
    Abstract:

    A methodology for the environmental impact evaluation over the life span of a Domestic Solar Hot Water System (DSHWS) is presented. The results are compared to the environmental consequences of the Conventional Energy form substituted and the total environmental gain is calculated. For the purposes of this analysis, the “Eco-indicator ’99” Life Cycle Impact Assessment methodology was adopted and the materials and procedures of the DSHWS production and utilization are evaluated.

  • Analysis of Renewable Energy Situation in Jordan
    Energy Sources Part B: Economics Planning and Policy, 2007
    Co-Authors: Eyad S. Hrayshat
    Abstract:

    Abstract Jordan, like most developing countries, has problems, constraints, and difficulties that mandate increasing renewable Energy (RE) technology utilization. The most effective argument in favor of the adoption of RE technologies in Jordan is that its lack of Conventional Energy sources is complemented by abundant RE resources. Because RE technologies are not complex, require less operating and maintenance costs and are inherently more environmentally benign than Conventional Energy sources foster their consideration by Energy policy makers as essential components of the national Energy balance. The most prudent approach to address this strategic issue is to alleviate the problems, constrains, and difficulties associated with each of the above-mentioned influencing factors. This paper analyzes the current Energy situation in Jordan, and discuses the importance of increasing the role of RE technologies in the Energy mix. It also discusses some success stories in the RE technologies domain, analyzes th...

  • Analysis of renewable Energy situation in Jordan

    Abstract:

    Abstract Jordan, like most developing countries, has problems, constraints, and difficulties that mandate increasing renewable Energy (RE) technology utilization. The most effective argument, in favor of the adoption of RE technologies in Jordan, is that Jordan's lack of Conventional Energy sources is complemented by abundant RE resources. Because RE technologies are not complex, require less operating and maintenance costs, and are inherently more environmentally benign than Conventional Energy sources foster their consideration by Energy policy makers as essential components of the national Energy balance. The most prudent approach to address this strategic issue is to alleviate the problems, constraints, and difficulties associated with each of the above-mentioned influencing factors. This paper analyzes the current Energy situation in Jordan and discuses the importance of increasing the role of RE technologies in the Energy mix. It also discusses some success stories in the RE technologies domain, analyzes the barriers affecting their development, and suggests future courses of action in order to attain their maximum utilization potential. It is believed that this paper will benefit Energy policy makers in Jordan, as well as in other developing countries.

  • On thermal Energy storage systems and applications in buildings
    Energy and Buildings, 2002
    Co-Authors: Ibrahim Dincer
    Abstract:

    This paper deals with the methods and applications of describing and assessing thermal Energy storage (TES) systems in buildings. Various technical aspects and criteria for thermal Energy storage systems and applications are discussed and Energy saving techniques and environmental impacts of these systems are highlighted with illustrative examples. An Energy and exergy analysis of thermal Energy storage systems and their sub-processes is presented for system design and optimization. An illustrative example is also given to demonstrate how exergy analysis provides a more realistic and meaningful assessment than the Conventional Energy analysis of the efficiency and performance of a thermal Energy storage system.
