Item PVSITES: Supporting large-scale market uptake of Building-Integrated Photovoltaic technologies(Institute of Electrical and Electronics Engineers Inc., 2018-11-26) Weiss, Ingrid; MacHado, Maider; Challet, Simon; Román, Eduardo; Tecnalia Research & Innovation; SISTEMAS FOTOVOLTAICOSThe identified large potential for energy savings in buildings led the European Commission to adopt Directive 2010/31/EU, mandating that all new buildings in Europe must be Nearly Zero Energy Buildings (NZEB) by 2020. Renewable energy technologies and in particular the integration of photovoltaic systems in the built environmentoffer many possibilities to enable NZEB realizations. However, a continuous development of the building-integrated photovoltaics (BIPV) market in the next years necessarily demands the compliance with strict requirements in terms of design flexibility, aesthetics, durability, cost reduction, grid integration, testing standards and operation & maintenance. Within thiscontext, a European consortium of 15 partners contributes to the Horizon 2020 PVSITES project, developing BIPV technologies and systems for large-scale market deployment. The project demonstrates an ambitious set of BIPV solutions, specially tailored to provide a comprehensive and robustanswer to market demands. This paper focuses on some of the major results achieved at the time of writing. These include a detailed BIPV market and regulatory framework analysis and recommendations for the standardization of BIPV products. Novel developments of glazed crystalline silicon modules for BIPV integration are presented, with both opaque and see-thru variations. Also included are the selection of a battery technology best suited for inclusion in a custom-made building energy management system (BEMS), as well as a BIMcompatible software tool to assist the design of BIPV projects by architects and construction actors.Item Standardized toolchain and model development for video quality assessment - The mission of the Joint Effort Group in VQEG(IEEE Computer Society, 2011) Staelens, Nicolas; Sedano, Iñigo; Barkowsky, Marcus; Janowski, Lucjan; Brunnström, Kjell; Le Callet, Patrick; FACTORYSince 1997, the Video Quality Experts Group (VQEG) has been active in the field of subjective and objective video quality assessment. The group has validated competitive quality metrics throughout several projects. Each of these projects requires mandatory actions such as creating a testplan and obtaining databases consisting of degraded video sequences with corresponding subjective quality ratings. Recently, VQEG started a new open initiative, the Joint Effort Group (JEG), for encouraging joint collaboration on all mandatory actions needed to validate video quality metrics. Within the JEG, effort is made to advance the field of both subjective and objective video quality measurement by providing proper software tools and subjective databases to the community. One of the subprojects of the JEG is the joint development of a hybrid H.264/AVC objective quality metric. In this paper, we introduce the JEG and provide an overview of the different ongoing activities within this newly started group.Item Volatile fatty acid platform - A cornerstone for the circular bioeconomy(2021-05-01) Velghe, F.; De Wilde, F.; Snellinx, S.; Farahbakhsh, S.; Belderbos, E.; Peral, C.; Wiedemann, A.; Hiessl, S.; Michels, J.; Pierrard, M. A.; Dietrich, T.; Alimentación SostenibleAnnually, the EU produces more than 100 million tonnes of urban biowaste, which is largely under-valorized and in some cases even still landfilled without any energy or material recovery. If Europe wants to be ready for the future, it will need to make better use of this large biomass potential within a circular economy approach. The research project funded by the European Commission under the Horizon 2020 programme entitled 'VOLATILE - Biowaste derived volatile fatty acid platform for biopolymers, bioactive compounds and chemical building blocks' aimed to produce volatile fatty acids (VFAs) from biowaste for reprocessing into products, materials or substances to close the material loop. During the project, the partners were able to obtain average volatile fatty acid yields of 627 g COD/kg organic matter (OM) for food waste, 448 g COD/kg OM for separately collected vegetable, garden and fruit waste (VGF) and 384 g COD/kg OM for the organic fraction of municipal solid waste (OF-MSW) at concentrations ranging from 12 to 48 g/L, 6 to 40 g/L and 13 to 26 g/L, respectively. A membrane filtration cascade consisting of micro-, ultra- and nano-filtration followed by reverse osmosis was identified as a feasible way to purify and concentrate the VFA effluent, making them a suitable carbon source for further fermentation processes. Besides technical optimization, socio-economic and legal aspects associated with this platform technology were also studied and show that although this technology is still in development, it is providing an answer to changing societal and market expectations both regarding organic waste treatment and bio-based production strategies. Based on the current technological, economic and market evolutions, it is expected that the VFAP will play an important role in organic waste treatment in the coming years.
