The integration of Grid-Connected PV systems into buildings or public areas is one of the most usual applications of the photovoltaic solar energy in developed countries. Since early 2009, the University is working on an ambitious project, the so-called UNIVERSOL project, where its main goal is to convert the University Campus in a big public area which combines the PV electricity generation with the common uses of a university place. The aim of this paper is to show to the scientific community the main results of this project and that the methodology proposed for the “large urban-area photovoltaic potential” estimation can be easily exportable to other locations with similar characteristics, so the photovoltaic generators integration examples proposed in this project, and the software tools used to represent it, can be helpful for other designers, taking into account that this project has been adapted to the new Spanish legislation. 26th European Photovoltaic Solar Energy Conference and Exhibition; 4068-4072

La variabilidad anatómica presente en los cerebros de pacientes limita la realización de análisis estadísticos acerca de la presencia o ausencia de una patología. En este artículo, presentamos una aproximación para la clasificación de imágenes de Resonancia Magnética (MR) cerebral de sujetos sanos y afectados por una patología. El enfoque se basa en un mapa de saliencia, el cual extrae regiones de cambio relativo en tres diferentes dimensiones: intensidad, orientación y bordes. Las regiones de interés obtenidas se utilizan como patrones para la clasificación de sujetos utilizando máquinas de vectores de soporte. El desempeño de la estrategia propuesta fue evaluado en un conjunto de 198 imágenes de MR extraídas de la base de datos OASIS y divididas en cuatro grupos, reportando una tasa de precisión promedio de y una tasa de error igual (Equal Error Rate) promedio de .

The aim of this report is to demonstrate and evaluate the potential of tall wheatgrass (Elytrigia elongata) to avoid GHG emissions and obtain lower economic costs in marginal areas of Spain. Our research built scenarios based on experimental plots (2 and 3 years growth) in 3 locations of Spain with completely different climate conditions (provinces of Girona, Soria and Palencia). In our experiences, we achieved an adequate establishment and biomass production, and assumed a rank of biomass yields until the end of the life cycle that is usually accepted to be about 15 years in many other studies in United States, Argentina and Eastern Europe where tall wheatgrass is extensively cultivated in marginal areas for sheep livestock production. Using our experimental plots and statistical information for economic inputs costs, we built 5 different scenarios per region considering a large range of biomass yields of tall wheatgrass. The analysis included a comparison with annual grasses economic costs calculated for a wide range of biomass yields of a previous study. We estimated GHG emissions savings for tall wheatgrasses and used our previous study (which had GHG emissions savings as well). Savings were calculated replacing natural gas electricity with electricity from biomass combustion in real power plants in Spain. In a wide range of yields, the results suggest that marginal areas might present a better performance with tall wheatgrass compared to annual winter grasses (cereals whole plant cuttings), thus producing biomass yields with higher GHG savings and lower economic costs at the farm level.

Climate Adaptive Facades are considered promising breakthroughs for the reduction of energy consumption, as energy exchange is enabled when the weather conditions offer benefits instead of threats. So far, conventional building envelops enhance thermal performance through opaque fa��ade components and static insulations. Therefore, natural resources from the building environment remain untapped. Little research has been done in Adaptive Opaque Facades, even if their dynamic behaviour shows a strong potential to exploit environmental resources. For the successful development of these innovative fa��ade systems, a balance between sophistication and benefit is necessary. To manage this objective, the implementation of Smart and Multifunctional Materials in the envelopes seems promising, as they are able to repeatedly and reversibly change some of its functions, features or behaviour over time in response to environmental condition. Consequently, to trigger the response of the envelope, no external actuator or complex software management would be necessary. Nevertheless, these materials do not fulfil all the fa��ade requirements by themselves. Thus, they need to be combined with other adaptive technologies and building elements. This paper shows an initial definition of different fa��ade configurations that include reactive materials which enable the adaptiveness of Opaque Fa��ade Systems. The desired results are new facade roles suitable for a temperate climate, according to the potential of these multi-performance materials in the external layer of the envelope: the dynamic temperature change of the external cladding through the solar reflectance change and the enhancement or prevention of thermal loses through Shape Changing Ventilated Facades. To achieve these new high performances, an ideal approach to the thermal behaviour of each fa��ade layer was done and required physical properties of each elements were highlighted. As a result, we propose a mapping of potentially suitable combination of reactive materials with other building elements that might enable the holistic adaptive thermal performance.

Concerns about climate change, diminishing social acceptance of traditional fuels, and technological innovations have led several countries to pursue energy transition strategies, typically by massive diffusion of renewable electricity supplies. The German ‘Energiewende’ has been successful so far in terms of deploying renewable power, mainly by applying particular feed-in tariffs, and by bundling public, academic, industrial and political support. So far though, only few EU member states proceed with a similar transition. In March 2014 CEOs of Europe’s major energy companies publicly opposed a fast and thorough transformation of electricity supplies to become fully renewable. In April 2014 the European Commission published new state aid guidelines, generally mandating renewable energy support mechanisms (premiums, tenders) of lesser performance than regularly adjusted, specific feed-in tariffs. The new guidelines are likely to be pernicious for the fast deployment of renewable electricity supplies. In light of these challenges, this position paper highlights two implications of power sector transitions. First, the engineering-economics theory of power generation systems needs fundamental revision, mainly since a growing share of power sources no longer function on command. Second, and based on the experience in Germany, the paper sketches out a strategy for a thorough transition of the power sector, which, in the end, also entails normative judgements. Deep changes in energy systems and associated ways of living require societal consensus building based on ethical considerations.

The integration of grid-connected PV systems into buildings or public areas is one of the most usual applications of the photovoltaic solar energy in developed countries. The University of Jaén (Spain) is a pioneering public organism in the field of grid-connected PV systems, as it proves the milestones developed by its IDEA research group in the last decades. The University is working in an ambitious project, the so-called UNIVERSOL project, where the necessary tasks are being carried out in order to evaluate the “photovoltaic potential” of the Campus of the University. For the implementation of this project, there are participating diverse research groups from the University of Jaén, which gives the project a multidisciplinary character. The different tasks assigned in the Universol project will let us obtain a Large-Scale deployment of photovoltaic systems in building integration, so it will convert this Campus in a big public area which combines the PV electricity generation with the common uses of a university place. 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 5212-5216

This paper presents a description of an open-source simulation tool (features, models and calculation procedures) that has been developed under the support of the European project called PVCROPS. The main advantage of this tool is that it uses as input just parameters guaranteed by the manufacturers of the different components of a PV plant. This way, it can be used in contractual frameworks to establish the expected energy yield of a PV plant, to check the actual performance of the PV plant with quality contractual procedures linked to SISIFO, and to assign responsibilities in the case of underperformance. The tool provides, among other simulation results, the energy yield, the analysis and breakdown of energy losses, and financial analysis. Furthermore the software can generate a technical report with the results obtained in the simulation. 31st European Photovoltaic Solar Energy Conference and Exhibition; 2190-2192
