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

We propose an on-the-fly statistical learning method to make a qualitative reduced-order model of the dynamics of a premixed flame quantitatively accurate. This physics- informed data-driven method is based on the statistically optimal combination of (i) a reduced-order model of the dynamics of a premixed flame with a level-set method, (ii) high-quality data, which can be provided by experiments and/or high-fidelity simulations, and (iii) assimilation of the data into the reduced-order model to improve the prediction of the dynamics of the premixed flame. The reduced-order model learns the state and the parameters of the premixed flame on the fly with the ensemble Kalman filter, which is a Bayesian filter used in the data assimilation of high-dimensional dynamical systems, e.g., in weather forecasting. The proposed method and algorithm are applied to two test cases with relevance to reacting flow and instability. First, the capabilities of the framework are demonstrated in a twin experiment, where the assimilated data are produced from the same model as that used in prediction. Second, the assimilated data are extracted from a high-fidelity reacting-flow direct numerical simulation (DNS). The results are analyzed by using Bayesian statistics, which provide the uncertainties of the calculations. This method opens up new possibilities for on-the-fly optimal calibration of computationally cheap reduced-order models when experimental data become available, for example, from sensors.

ON 16 NOVEMBER 2000, the final report of the World Commission on Dams (WCD) was launched in London, in the presence of South Africa’s former president Nelson Mandela. This represented a remarkable milestone in the history of dam policy and politics. During its two-year existence, WCD had conducted the most extensive review of research and evidence regarding the planning, impacts, and management of large dams. It had engaged with numerous stakeholders around the globe. It also made comprehensive recommendations about how to improve dam planning and management.

Over the past few years, remarkable developments in piezoelectric materials have motivated many researchers to work in the field of vibration energy harvesting by using piezoelectric beam like smart structures. This paper aimed to present the most recent application of a dual function piezoelectric device which can suppress vibration and harvest vibration energy simultaneously and a brief illustration of conventional mechanical and electrical TVAs (Tuned Vibration Absorber). It is shown that the proposed dual function device combines the benefits of conventional mechanical and electrical TVAs and reduces their relative disadvantages. Conversion of mechanical energy into electrical energy introduces damping and, hence, the optimal damping required by this TVA is generated by the energy harvesting effects. This paper presents the methodology of implementing the theory of 'electromechanical' TVAs to suppress the response of any real world structure. The work also illustrates the prospect of extensive applications of such novel "electromechanical" TVAs in defence and industry. The results show that the optimum degree of vibration suppression of an electronic box is achieved by this dual function TVA through suitable tuning of the attached electrical circuitry

One of the distinguishing features of the civil aero-engine market is its high competitiveness. The costs and risks associated with new projects are such that the difference between two apparently equally attractive options could result in success from one and a threat to the survival of the company from the other. To conceive and assess engines with minimum global warming impact and lowest cost of ownership in a variety of emission legislation scenarios, emissions taxation policies, fiscal and Air Traffic Management environments, a Techno-economic and Environmental Risk Assessment (TERA) model is needed. TERA incorporates multi-disciplinary modules for modelling gas turbine and aircraft performance, estimation of engine weight, noise and emissions as well as environment impact and operating economics. The TERA software is integrated with a commercial optimiser and provides a means for cycle studies. It is to be expected that new legislative and fiscal constraints on air travel will demand an extension to the customary range of asset management parameters. In such a business environment there is potential for TERA to develop into a useful tool for aircraft and engine asset management. This paper presents a description of this tool as well as gives some results from scenario studies.

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.

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
