The availability of financial resources has been pointed out as one of the determining factors for the investment in renewable self-consumption solutions for the energy transition in the European Union. In economic terms, the barriers to investment are related to low levels of profitability and difficulties in accessing financing in some European regions. These barriers must be overcome to foster a sustainable energy transition. However, this topic of analysis is still underexplored in the literature to date. This study provides a characterisation of the financial resources applied to self-consumption from an economic–financial approach to the decision-making investors in a case study in Spain from a novel focus on the subject. The relevance of alternative financial resources as a mechanism to reduce existing barriers is revealed through the analysis of the active role that installers play in making investment decisions, facilitating the growth of self-consumption. The alternative financial channels and the bank intermediation for renewables are topics of interest to promote the energy transition towards a low-carbon economy.

Innovative and sustainable energy technologies are needed in the transition of energy toward a circular economy. Because of the use of renewable energy and carbon utilization, power-to-gas could be a cutting-edge technology that supports the circular model in future sustainable energy markets. However, this technology faces new technical and socio-economic challenges. The use of power-to-gas is limited because of barriers that limit the mobilization of investment capital. In addition, social and economic impacts on the territories in which these facilities are located are under study. In this context, the aims of this paper are: (i) To explore the determinants and barriers for power-to-gas technology to enhance the understanding of investment in innovative energy technologies; and (ii) to support effective policymaking and energy companies’ decision-making processes. This study defines and measures, from a circular economy perspective, the main impacts of the deployment of this technology on a territory in terms of volume of investment, employment generation, and CO2 capture. The study also provides a simplified methodology to contribute to the analysis of the use of power-to-gas. Finally, it improves the knowledge of the socio-economic impact of this cutting-edge technology for the transition of energy to a zero-emission scenario.

Renewable distributed energy and self-consumption are promising and sustainable solutions in the energy-transition scenario for moving toward a circular economy. In this future scheme, prosumers are expected to play a leading role in the forthcoming sustainable energy market, facing new technical, economic, and financial challenges as energy producers at a small scale. In fact, the adoption of photovoltaic (PV) self-consumption systems requires mobilizing capital for investment and their interaction with the market. In this scenario, the aim of this paper was to explore insights into the decision-making process of prosumers to enhance the understanding of self-consumption deployment and to support effective policymaking. This study contributes to the state of the art by defining and classifying determinants of the energy prosumers’ decision-making process and their relevance using a heuristic approach. Potential measuring tools and methods are analyzed through a specific case study of Spanish prosumers.

El modelo de enseñanza tradicional ha perdido su utilidad en un mundo cada vez más digitalizado y globalizado. Por ello, en los últimos años se está cuestionando seriamente el papel que jugarán las universidades en las próximas décadas. Si no crean valor añadido a las clases presenciales, perderán alumnos y podrían llegar a desaparecer. El modelo pedagógico de aula inversa podría ser la respuesta natural a muchos de los retos a los que debe enfrentarse la Universidad si quiere seguir manteniendo su posición de liderazgo en la sociedad.El presente trabajo recoge y compara las experiencias sobre aula inversa llevadas a cabo en varias asignaturas del área de Máquinas y Motores Térmicos de la Universidad de Zaragoza durante los últimos tres cursos académicos. A partir de la experiencia adquirida, se recogen pautas para planificar adecuadamente la aplicación de aula inversa, tanto en sesiones de laboratorio como en clases magistrales.

The diffuse nature of road transport and the heterogeneity of heavy vehicles have hindered the implementation of emissions accounting systems. Even though there are emission factors in well-known databases, these factors have commonly been designed in industrialized countries, which might have geography, type of roads, and operating conditions different to other countries. This paper proposes a method for the energy consumption and emissions estimation based on vehicle operating conditions in regions with different topology, such as Colombia, Malaysia, and Spain, as case studies. Moreover, the environmental impacts of fuel production in each country are calculated. The diesel consumption on mountainous roads for a full loaded rigid truck in Colombia was 45 L/100 km, compared to averages between 22–26 L/100 km from other sources usually applied. In contrast, the diesel consumption for an articulated truck on a hilly road in Spain from both the proposed method and generic databases coincided in 31 L/100 km. The vehicle speed, load, and road gradient also generated large variations up to 145% in the air pollutants’ estimation. This study contributes to the need for more research about emission factors and tools that facilitate and reduce uncertainty in the environmental accounting in freight companies in different geographies.

Self-consumption energy facilities are presented as viable and sustainable solutions in the energy transition scenario in which many countries are immersed. However, they rely on dispersed and private investments in the territory. Given the uneven growth in the number of self-consumption facilities in Europe, the main objective of this study is to identify and measure the investment determinants in self-consumption facilities. To this end, the main influential incentives and barriers are identified through the aggregate analysis of the regulatory framework for self-consumption in several European countries, and the empirical characterization of Spanish facilities as a multiple case study, to define the common features of the investments made. The technical, economic, and financial characterization of real self-consumption facilities in climatic zones of southern Europe is a significant contribution of the present work. There are few samples of this type in the studies published to date, which have mainly been prepared from case studies or statistical data without identifying particular facilities. Cost-related variables have been identified as the most important variables in private investment decisions, and potential influential factors on these variables that could be regulated have been pointed out as relevant. It is also worth highlighting the elaboration of an analytical framework based on this conceptual approach, which has been proven to be useful to depict regulatory scenarios and to compare the positioning for the development of self-consumption systems in different countries. A model that transfers the influence of the determining factors to the deployment of self-consumption under specific regulatory scenarios has been developed and applied to the case of Spain. As a general reflection, to increase the adoption of this kind of technology and encourage consumers to make private investments, policies for renewable energy must consider self-consumption and microgeneration as the main axis, by increasing the availability of energy when necessary. For instance, the promotion of energy storage from these kinds of facilities could receive priority treatment, as well as rewarding the electricity surplus in the interests of security of supply in a period of energy transition towards a new, more sustainable model. Incentive schemes, aids to compensate for the additional costs resulting from the battery storage or easing restrictions in terms of contracted power would foreseeably increase the rates of adoption of the technology, favoring its faster development in terms of research and development and product innovation.

The actual energy consumption and simulated energy performance of a building usually differ. This gap widens in social housing, owing to the characteristics of these buildings and the consumption patterns of economically vulnerable households affected by energy poverty. The aim of this work is to characterise the energy poverty of the households that are representative of those residing in social housing, specifically in blocks of apartments in Southern Europe. The main variables that affect energy consumption and costs are analysed, and the models developed for software energy-performance simulations (which are applied to predict energy consumption in social housing) are validated against actual energy-consumption values. The results demonstrate that this type of household usually lives in surroundings at a temperature below the average thermal comfort level. We have taken into account that a standard thermal comfort level may lead to significant differences between computer-aided energy building simulation and actual consumption data (which are 40–140% lower than simulated consumption). This fact is of integral importance, as we use computer simulation to predict building energy performance in social housing.

Flipped classroom model (FCM) and educational videos have been applied in several subjects related to thermal engineering. Results have been evaluated by questionnaires, observation in the classroom and also number of videos visualization. In general, students evaluate positively the application of the new methodologies, although some suggestions for improvement have been obtained. In particular, the use of videos can reduce some of the difficulties of FCM related to previous preparation by students. Finally, students’ marks have been compared to number of videos watched, and a positive (although weak) trend has been seen.

In Europe, the proportion of social housing is high, and such houses tend to be inhabited by below average-income households, which are particularly vulnerable to energy poverty. This article proposes a new methodological approach for defining an index for household energy vulnerability assessment. This method can be used to improve the management of social housing. After establishing a heuristic framework for household energy poverty–which stems from different causes such as income, the characteristics of the residence, energy installations, and the energy-consumption habits of household members–multi-criteria analytical methods, based on the aggregation of indicators which reveal the conditions leading to energy poverty, have been applied, and effective means of intervention are proposed. The method is also applied to a sample of social houses and thus validated as a useful tool in decision-making processes which concern the management of social housing from a household energy-poverty perspective.

Domestic solar hot water systems (SHWS), which are used to reduce domestic energy use, represent one of the most widely known technologies of solar thermal applications. Taking into account the sizing of these systems during its design phase, it is also important to consider the effects on the environment of their use from a life cycle perspective. An evaluation method based on the Life Cycle Assessment (LCA) methodology is used in this paper to analyse the environmental implications of SHWS considering the production, use, maintenance and end-of-life stages. As a case study, 32 different types of SWHS to meet the hot water demand (HWD) of 2 dwellings and 2 hotels, located in the region of Aragón in Spain, are studied. The aim of the case study is to compare the environmental performance of SHWS and to select the best environmentally friendly solution while considering their energy pay-back time (EPBT).\ud \ud From an environmental point of view, comparing the results obtained in all cases studies, e.g., in terms of kg CO2 eq, the use of biomass as fuel for the auxiliary system in each SHWS considered provides the greatest environmental benefit in comparison with the other fuels, usually followed by the use of natural gas. However, in terms of the EPBT, because biomass is the fuel with lowest environmental impact and associated embodied energy, the avoided embodied energy due to the solar contribution in SHWS is the lowest in the biomass case, thereby resulting in a higher value of the EPBT.This paper was developed from the results obtained in the framework of the "UrbiLCA" project co-financed by the European Regional Development Fund (ERDF) - SUDOE Interreg IV B, the ECOURBAN project "Methodology for the energy and environmental impact assessment and the ecodesign of urban areas", co-financed by the Spanish Ministry for Science and Innovation (Spanish National Plan for Scientific Research.

Sustainable transportation infrastructure and travel policies aim to optimise the use of transportation systems to achieve economic and related social and environmental goals. To this end, a novel methodology based on life cycle assessment (LCA) has been developed in this study, with the aim of quantifying, in terms of CO2 emissions equivalent, the impact associated with different alternatives of waste collection systems in different urban typologies. This new approach is focussed on saving energy and raw materials and reducing the environmental impact associated with the waste collection system in urban areas, as well as allowing the design and planning of the best available technologies and most environment-friendly management. The methodology considers a large variety of variables from the point of view of sustainable urban transport such as the location and size of the urban area, the amount of solid waste generated, the level of social awareness on waste separation procedures, the distance between houses and waste collection points and the distance from the latter to the possible recovery plants and/or landfills, taking into account the material and energy recovery ratio within an integrated waste management system. As a case study, two different waste collection systems have been evaluated with this methodology in the ecocity Valdespartera located in Zaragoza, Spain, consisting of approximately 10,000 homes: (i) a system based on traditional truck transportation and manual collection, and (ii) a stationary vacuum waste collection system. Results show that, when operating at loads close to 100%, the stationary collection system has the best environmental performance in comparison with the conventional system. In contrast, when operating at load factors around 13% the environmental benefits in terms of net CO2-eq. emissions for the stationary collection system are around 60% lower in comparison with the conventional one.

This paper demonstrates how to achieve energy savings in the construction and operation of buildings by promoting the use of life cycle assessment techniques in the design for new buildings and for refurbishment. The paper aims to draw on the application of a specific methodology for low energy consumption, integrated planning, environmental performance evaluation of buildings, and design for sustainability and LCA techniques applied to buildings. The ENergy Saving through promotion of LIfe Cycle assessment in buildings (ENSLIC) methodology based on LCA for use in an integral planning process has been promoted to stakeholders who require a means to optimize the environmental performance of buildings. Feedback from the stakeholders has facilitated the creation of simplified LCA guidelines, a systematic approach guiding the user through the alternative options regarding software choices, their strengths and weaknesses, the databases available, the usefulness of different indicators, aggregation, definition of limits and options for simplifying the process. As a result, this paper presents the applied results of a case study where this methodology is implemented serving as an energy savings evaluation tool for decision makers, end-users, professionals involved in the different stages of construction, etc. Finally, it is demonstrated how LCA can facilitate comparisons between different buildings, showing the influence of all variables on a building’s life cycle environmental impact and showing the potential for energy savings. Removing market barriers to sustainable construction is actually stricter and this is good news for promoting higher energy efficiency in buildings.

It is widely accepted that eco-innovation is the direction to make progress towards a sustainable innovation. Public and private actors seem to share a common point of view and agreement on the benefits of implementing eco-innovation. If this is the case, why eco-innovative activities are still exceptional and exemplary instead of being the usual reasoning and inspiring driver for all kind of actions? Going in depth into the reasons why eco-innovation techniques are not broadly spread, the main one is the lack of internalization of this attitude in all the everyday actions taken by companies and employees in the form of social responsibility. Definitively, society as a whole is responsible for the eco-innovation promotion. Large companies have long ago incorporated Social Responsibility into their strategic planning and invest on innovation as a competitive advantage. However, they are reluctant to contribute to the eco-innovation. Therefore, universities and technology centers (TCs) have to play this role and link the private sector, specially medium, and small size companies, with the society needs. However, Universities are not often leading the eco-innovation initiative. Currently, in the case of Spain, it is observed a huge gap between the scientific research efforts made by the Public University and the academic offering and the real needs of the private companies. In fact, mixed structures as TCs are needed in order to overcome this disconnection, increasing opportunities for subsequent cooperation in eco-innovation projects. This paper points out the causes of the Spanish R&D and innovation lag, and highlights the reasons of the disconnection between public and private research for innovation, while giving hints on what is working fine and what needs to be reviewed to catch up with the R&D reference countries in Europe.
