The COLEOPTER (COncertation LocalE pour l’Optimisation des Politiques Territoriales pour l’Energie Rurale) project develops an integrated approach to the energy efficiency of public buildings that links technical, social and economic challenges. COLEOPTER addresses two energy efficiency challenges in buildings: difficulties for rural municipalities to act and carry out work despite the positive local impact (i.e., energy savings and local employment) and a lack of awareness of building challenges, which leads to irrational use of energy/water and low renovation rates.

Papachristou, Ioanna Anna; Rosas Casals, Martí
The paper presents a methodology employed to measure the subjective dimension of quality of life (QoL) responding to subjective well-being (SWB), based on the perceptions of people using and interacting with the urban and social space. To check the levels of satisfaction, two surveys were created using the fundamental human needs of the Human Scale development paradigm as study categories. The selected places constituting the case study refer to two different scales of the same urban area corresponding to i) Vila de Gràcia neighbourhood and ii) Virreina square, of the Gràcia district of Barcelona (Spain). Results show scores per need and in total (SWB) are lower for the neighbourhood scale. The classification of questions per need favours theidentification of potential problems and can be used to implement measures of improvement. By using combined intervention axes we prove that an average 20% increase in SWB is possible for both cases.

La isla Lesbos ( Grecia) constituye un lugar fronterizo importante de paso de flujos internacionales de migración procedentes del Asia y África y dirigidos hacia el Norte - Occidente de Europa. Este trabajo explora las percepciones de la gente de su capital, Mitilene. La investigación se centra i) en 200 encuestas y entrevistas semidirigidas, realizadas durante los meses de julio y agosto de 2015 en cuatro barrios de la ciudad, con diferenciaciones históricas y socio-espaciales y ii) en un trabajo de observación participativa entre 2015-2018. Para el procesamiento de los resultados se han generado y analizado redes semánticas de palabras que aparecen juntas en el discurso de las personas entrevistadas. Los resultados demuestran que las políticas de migración, el vínculo con el lugar de residencia y su proceso de formación social e histórica (eco-paisajes vividos), el estatus social en el trabajo, la edad y el género, influyen de una manera compleja en las percepciones de los y las habitantes de Mitilene sobre el tema de la migración. Actualmente y después del acuerdo entre EU y Turquía y los sucesivos cambios en las políticas migratorias, se nota un cambio a la opinión de los habitantes que ya se podría caracterizar como socialmente construida.; Lesvos Island (Greece) is an important border crossing point for international migration flows originated from the Asia and Africa and directed towards the North - West of Europe.

The effects of climate change are significant on groundwater recharge. In regions with 15 socioeconomic structures highly dependent on this kind of water source, expected positive 16 and negative variations in temperature and precipitation respectively, will have a negative 17 effect on the recharge of groundwater and, consequently, on the future well-being of their 18 inhabitants. In this paper we aim at estimating the effect that changes in climatic 19 parameters will have on groundwater recharge in one of these areas: the Yucatan Peninsula 20 (Mexico). We apply a monthly water balance model to five distinct Global Circulation 21 Models in the near horizon (2015-2039), with RCP 4.5 and 8.5. In average terms, our 22 results estimate a current recharge between 118 ± 33 mm per year, which represents around 23 10 % of the total annual precipitation, and a reduction of 23% of groundwater recharge, a 24 result which clearly threatens the future socioecological equilibrium of the region.

WP5 Final report
Horta Sellares, Frederic; Arranz Piera, Pol; Pérez Foguet, Agustí; Giné Garriga, Ricard; Velo García, Enrique
The European bioenergy sector requires a wide promotion for strong investments in regional sustainable supply chain solutions. SMEs are central in the value chain in local bioenergy markets, as they are operating throughout all the stages of bioenergy mobilisation, from forestry management to energy plants or even energy commercialisation to final consumers. One of the major barriers that SMEs face when assessing potential bioenergy operations is the difficulty to access adequate financing; WP5 within project SECURECHAIN aims to analyse such difficulties and contribute to overcome them. The specific objectives of WP5 are:
• O5.1 Carry out targeted market feasibility surveys, pre-checks and develop a risk assessment tool to support the implementation of priority SSCM pilot projects
• O5.2 Mentor companies’ capital call strategies tailored to investor types and upgrade corporate finance disclosing in accordance with International Financial Reporting Standards (IFRS)
• O5.3 Foster lobbying actions and dialogue between financial players and bioenergy market actors to promote the portfolio of investment proposals
This deliverable D5.3 is the final report of the activities within WP5, mainly about period 2 from September 2016 to July 2018. The market pre-check (T5.1) was carried out in phase 1 and reported in deliverable D5.1. The risk assessment analysis (T5.2) performed, the continuous financial mentoring (T5.3) being worked out with the SME business projects, and the roadshows (T5.4) that have been attended, as well as planning activities that were performed during the final year of the project, are documented in this report.

The study of one of the components, the heat accumulator, of Low Thrust Cryogenic Propulsion systems (LTCP),
is of scientific interest in the framework of ISP-1 project [1]. This device stores thermal energy from the fuel cell
that provides electrical energy to the whole system. This thermal energy is employed for the pressurization of the
propellant tanks. Two different types of heat accumulators are present in the LTCP system: the High Temperature
Accumulator (HTA) and the Low Temperature Accumulator (LTA). A numerical model is being developed [2] in
order to predict the thermal behavior of the LTA and having a tool for its design in the next future. Experimental
results of ISP-1 partners of DLR are being used for the validation [3], [4].

Papachristou, Ioanna Anna; Rosas Casals, Martí
Where we live affects all aspects of our life and thus our happiness. In recent years, and now for more than half of the population of the Earth, our place of residence or activity has been increasingly transformed into an urban one. However, while the impact of happiness studies has grown in importance during the last twenty years, we note that concepts like subjective well-being or happiness itself find it difficult to penetrate the planning and design of cities and truly affect the field of urban studies. In this paper we map the temporal evolution of the fields of happiness and urban studies into dynamic networks obtained by paper keywords co-word analysis. In order to reproduce the changes in its topology, a one-parameter spatial network model is presented. The results suggest an explanation for the level of penetration of these two fields in particular, but they also explain how different related academic or scientific fields evolve and pervade each other as a function of “conceptual distances” which in this case are mapped into Euclidean ones. The results and methodologies developed in the context of the happiness and urban studies keyword network could be useful for a systematic study of other complex evolving networks.
