Mediterranean Fish

<p>In this paper we propose a framework for energy audit and renewable energy utilization for a Mediterranean fish hatchery station. A concise literature review concerning the use of renewables in aquaculture is provided, followed by a step by step framework for energy audit in aquaculture stations. The developed framework is subsequently applied to a real case study concerning an aquaculture unit in Greece. A combined PV and Solar-Thermal panel project is proposed, based on the energy audit results. The well-known clean energy software RETScreen, developed by Natural Resources of Canada, has been utilized as an assessment tool of the proposed project. It was found that that the proposed project could not fully cover the electric and thermal load of the station; nevertheless, the project is economically viable and could de realized, provided that the necessary financial resources become available to the entrepreneurs.</p>

Technical Requirements

Airports are key components of the global transportation system and are the subject of continuous sustainability improvements. Promoting clean energy sources and energy-efficient practices can help attain major sustainability goals at airports around the world. Although small airports are greater in number, most of the “sustainability” attention has been given to large airports. Small airports are typically located in rural areas, making them excellent candidates for renewable energy. This paper focuses on the planning and selection of renewable energy systems as a strategic method to reduce energy use and increase electric power reliability at small-scale airport facilities. The target system may use a combination of renewable energy sources to produce electrical power for the on-site facilities. The framework details include methods of energy collection, power production, and energy storage that are environmentally sound. A small airport serving a dual role as a flight training facility was used as case study. In the case study, systems engineering methodology was adapted to the small airport/ renewable energy domain in order to effectively identify stakeholders and elicit user requirements. These, coupled with industrial standards, relevant government regulations, and a priori constraints, are used to derive the initial requirements that serve as the basis for a preliminary design. The proposed framework also contains provisions for an on-site assessment of existing airport energy needs, sources, providers, and location-specific assets and challenges.

Lime Plaster

Hemp-lime composite is a natural material, which is being increasingly used and studied in the construction sector, thanks to its recyclability, hygrothermal comfort and healthiness features. The aim of this paper is to test the benefits in terms of energy efficiency achieved through the use of hemp-lime composite as insulation in a possible refurbishment intervention. With the aim of extending the knowledge about the benefits achieved through from the integration of this natural material into construction production process, a real building in south of Italy was selected and a substitution of the standard gypsum-lime plaster with a hemp-lime one was simulated by means of a specific software (Termus® by Acca Sotware, Bagnoli Irpino, Italy), serving for the assessment of the energy performance. Case study analysis highlighted the good thermal insulation properties of hemp-based plaster, allowing thermal dispersion to decrease in the winter season and improve the summer performance of the walls by approximately 20% compared to traditional plaster. This results in a one-level improvement of the building in energy classification according to Italian regulation.

Educational Tool

Utilizing renewable energy systems as an educational tool for students creates not only a source for clean energy; it also provides a tangible way to increase their knowledge about science. Education is an essential element in the response to climate change. Students play an important role in addressing the issues of our planet, of which climate change is paramount. This case study examines why Georgia House Resolution 689 (HR689) did not pass in its original legislative form. Further, the study addresses how Georgia Power's opposition was key to getting the resolution pulled from the Debate Calendar resulting in a privilege resolution substitute. Suggesting that in regions of the Deep South passing any declaration which expressly supports alternative energy initiatives that increase awareness of climate change will be met with stiff opposition.

Development of creative and cultural sector, which is based on internal resources of the territory, can ensure competitive advantage; and several factors of competitive advantage based on resources can be defined. Those factors are human capital, tangible and intangible potential as well as financial resources. The purpose of this paper is to elaborate on the importance of creativity as competitive advantage factor and to assess unique resources (tangible, intangible potential, human capital, financial resources) potentially leading to innovation in two EU member states, Slovenia and Slovakia. The paper presents the case study analysis and comparison of current and potential future situation in creative and cultural industries in Slovakia and Slovenia. The results of the study suggest that the foundations for the development of the creative and culture sectors are quite different in those two countries, and Slovenia tends to exhibit stronger current and potential future position in those industries compared to Slovakia.

This document analysis the methods of stimulating renewable energy (RES) in various countries, describes the barriers and problems that hinder the development of alternative energy. Studies conducted in countries with a developed renewable energy sector will allow us to conclude that the development incentive systems (Feed-in-tariff (FIT), Renewable Energy Portfolio Standard (RSP), auctions, reverse auctions and various tax incentives) have had the required impact and the government of such countries has moved to establish parity between renewable and traditional energy, as well as to optimize the systems for promoting the development of clean energy. Green energy in countries that are actively developing renewable energy are building models and infrastructures based on the experience and methods of solving the problems of countries with a developed RES support system.

This article examines the barriers to brownfield redevelopment through a case study analysis of four cities in two Great Lakes states. Four key barriers are identified and investigated: legal liability, limited information, limited financial resources, and limited demand for the properties. Perceived liability emerges as a dominant barrier, and one that compounds the other three barriers. The article analyzes how and why liability perceptions affect stakeholder behavior and provides lessons learned for promoting brownfield redevelopment.
