One of the greatest challenges facing the European Union is the conversion of the existing residential building stock into nearly zero-energy buildings (NZEBs) by 2050 through energy renovation, given that the residential sector is one of the largest consumers of final energy and that approximately two-thirds of existing dwellings were built before 1980. The objective of this study is to assess the energy, environmental, and economic impacts of the energy renovation of thermal envelopes of existing multi-family buildings in the hot and temperate climate zones of Spain by using life cycle cost analysis (LCCA) to determine the optimal thicknesses of insulation to be added to the walls, roof, and first floor framework of the buildings and replacing existing building openings to achieve NZEBs. Four thermal insulation materials are considered with four different heating and cooling systems and ten different models. With the methodology developed, the best energy renovation solutions are estimated and then thermally simulated. In total, 67 of the 576 proposed energy renovation solutions achieve NZEBs. This study fills in the gap between LCCA estimates and reality.

This paper deals with the exergy analysis of a thermal power plant using different fuels, including biodiesel. The main goal is to understand the effect of design parameters and chemical dissociation of combustion products on energy and exergy efficiencies. Mass, energy and exergy analyses are made of the main components of the system, considering six different sources of irreversibilities: combustion chamber, heat transfer process, steam condensation, flue gas emission to the atmosphere, pump and frictional reheat at the steam turbine. Grassmann diagrams highlight the exergy flows and where the potential improvements exist. Results are obtained through ThermoCombustion, a virtual lab for combustion processes. The exergy analysis shows that the maximum source of exergy destruction is the boiler, followed by chimney exhaust, then steam turbine, and the condenser. Unlike the traditional methods, in this work, it was possible to distinguish between the irreversibilities thermal (due to the heat transfer) of the intrinsic irreversibility of the adiabatic combustion (associated with the chemical reactions and the viscous friction) in the steam boiler. The exergy loss distribution indicates that boiler irreversibility yields the highest exergy loss in the power plant. The use of the fuels with a simple molecular structure containing oxygen molecules will reduce the exergy destruction. The destruction of exergy in the reactive process decreases if the combustion temperature is increased, although this would lead to increases in NOx emissions. The regenerative cycle reduces total irreversibilities, increasing exergy efficiency.

The residential sector of the European Union consumes 27% of the final energy of the European Union, and approximately two-thirds of the existing dwellings in the European Union were built before 1980. For this reason, the European Union aims to transform the existing residential building stock into nearly zero-energy buildings by 2050 through energy renovation. The most effective method to achieve this goal is to increase the thermal insulation of opaque elements of the thermal envelope. This study aims to assess the energy, environmental and economic impacts of the energy renovation of the thermal envelopes that are typical of the existing multi-family buildings of the 26 provincial capitals in the cold climate zones of Spain. To achieve this goal, the insulation thickness to be added to the walls, roof and first floor framework is optimized by a life cycle cost analysis, and the existing building openings are replaced, thus minimizing both the total heating costs and the total heating and cooling costs. The study uses four thermal insulation materials for four different heating and cooling systems in 10 different models. The results obtained will be used to propose energy renovation solutions to achieve nearly zero-energy buildings both in Spain and in similar Mediterranean climate zones.

At present, LNG vessels without reliquefaction plants consume the BOG (boil-off gas) in their engines and the excess is burned in the gas combustion unit without recovering any of its energy content. Excess BOG energy could be captured to produce H2, a fuel with high energy density and zero emissions, through the installation of a reforming plant. Such H2 production would, in turn, require on-board storage for its subsequent consumption in the propulsion plant when navigating in areas with stringent anti-pollution regulations, thus reducing CO2 and SOX emissions. This paper presents a review of the different H2 storage systems and the methods of burning it in propulsion engines, to demonstrate the energetic viability thereof on board LNG vessels. Following the analysis, it is identified that a pressurised and cooled H2 storage system is the best suited to an LNG vessel due to its simplicity and the fact that it does not pose a safety hazard. There are a number of methods for consuming the H2 generated in the DF engines that comprise the propulsion plant, but the use of a mixture of 70% CH4-30% H2 is the most suitable as it does not require any modifications to the injection system. Installation of an on-board reforming plant and H2 storage system generates sufficient H2 to allow for almost 3 days’ autonomy with a mixture of 70%CH4-30%H2. This reduces the engine consumption of CH4 by 11.38%, thus demonstrating that the system is not only energy-efficient, but lends greater versatility to the vessel.

The European Union, through the Energy Performance of Buildings Directive and the Energy Efficiency Directive, has been establishing requirements and expectations regarding energy savings and efficiency in buildings. The objective of this study is to explore energy rehabilitation solutions for educational buildings of the 1980s in cold climate zones of Spain by applying the corresponding adaptation of the European legislation, which is the Basic Document for Energy Saving of the Technical Building Code. The evolution of regulation is studied using three cases, and 12 proposals for achieving nearly zero-energy educational buildings are studied. The analysis of the results obtained shows how changes in energy and environmental policies affect those buildings. Regarding the baseline building, average reductions of more than 66% in non-renewable primary energy consumption and of more than 71% in CO2 emissions were observed. Additional reductions of at least 10% in non-renewable primary energy consumption and 8% in CO2 emissions are achieved with the alternatives proposed to achieve nearly zero-energy educational buildings. The knowledge of the sector is deepened with this study, which allows the design of future energy rehabilitation policies and promotes policy changes.

The European Energy Performance of Buildings Directive can contribute to developing energy savings and efficiency regulations in the growing Latin American residential sector. This research focuses on evaluating the impacts of aspects that are related to the use of solar thermal energy to partially meet domestic hot water needs using Spanish and Chilean regulations as a reference. The objective of this work is to evaluate the characteristics of the thermal solar systems that are necessary to comply with the regulatory requirements of both countries and the possibility of replacing these systems with electric heat pumps in multifamily buildings in the main Chilean communes. The best regulation for maximizing the solar thermal energy in the different solar climate zones and the main characteristics of the electric heat pumps that would achieve the same primary energy savings or the same CO2 emissions reductions as thermal solar systems were identified. It is clear from studies of this type that the existing legislation can be significantly improved. It is necessary to broaden the understanding of the other aspects of the European Energy Performance of Buildings Directive for its possible implementation in Latin American countries.

In Spain, the regulation of energy savings in buildings has evolved in parallel with the Energy Performance of Buildings Directive (EPBD). With the upcoming Basic Document on Energy Saving of the Technical Building Code (CTE-DB-HE 2018), nearly zero-energy buildings (NZEBs) are addressed for the first time, including both new buildings and renovated buildings. The goal of the present work is to present the innovations of the forthcoming modifications introduced by the implementation of the EPBD 2010 in Spain, highlighting the energy rehabilitation possibilities offered, with a goal of achieving the classification of all buildings as NZEBs by 2020. To illustrate these modifications, a complete case study is analyzed, in which the improvements introduced with respect to the previous regulation are checked against the new renewable energy contribution requirements for the production of domestic hot water, energy demand limits and energy consumption limits of the upcoming CTE-DB-HE 2018. In this way, we clarify how the energy consumption of the residential building stock is expected to be reduced and how policies that favor building energy rehabilitation can be encouraged to achieve the European goals for 2020 and 2030.

To mitigate the effects of global warming, the European Union must reduce its dependence on foreign fossil fuels to produce energy. Biomass from forests and agroforestry residues are a readily available source of domestic renewable energy. However, further technological developments must be made in order to foster its use in machines and thermal engines. The present study analyses the current situation of biomass energy in Spain as well as its future prospects, potential challenges and opportunities moving forward. This analysis is performed through a review based on bioenergy resources, technology and management to provide recommendations and carry out a more comprehensive energy assessment. Non-food biomass resources are intended to be useful in the development of bioenergy industrial sector. This study is applied to Spain due to its remarkable forests and wealth of agricultural areas. The methodology is based on three phases of energy conversion: resources, technology and management. The main achievements are pathways definition from resource to bioenergy application in Spain. Bioenergy advances offer management drive forces to meeting the energy and environmental challenges in the European Union.

Self-sustaining systems are considered by researchers, policy makers and investors to be one of the most interesting technologies in the world. The proportion of energy being derived from biological sources is increasing due to processes for converting wood biomass. In rural areas in Europe, bioenergy can effectively alleviate energy dependence on external energy resources for green energy development. An applied bioenergy study was conducted in Ezcaray, Spain, a forested village representative of rural areas in cold climate zones in southern Europe. The present study aims to evaluate and use existing forest resources and assess their thermal potentiality and replicability in remote areas via self-sustaining systems for distributed thermal production. Knowledge gaps and technology options for assessing and meeting sustainability criteria are analyzed. The implemented methodology considers a combination of mass, energy and costs from the source to the bioenergy heating system, and it assesses the techno-economic feasibility of such systems against boilers using different fuels. Two proposals were studied, namely, starting a pellet mill for the thermal system market and replacing existing boilers with biomass in self-sustaining systems. The first proposal is profitable, with a selling price equal to or higher than 146.04 €/t. In the second proposal, the non-renewable primary energy consumption in the studied households was between 13- and 15-times higher with fossil fuel boilers than with biomass boilers. In both cases, thermal systems in rural areas may effectively alleviate dependence on non-renewable energy to increase green energy use in Europe by 2020.

This article offers reasons to defend the use of generic behavior models as opposed to specific models in applications to determine component degradation. The term generic models refers to models based on operating data from various units, whereas specific models are calculated using operating data taken from a single unit. Moreover, generic models, used in combination with a status indicator, show excellent capacity for detecting anomalies in the equipment and for evaluating the effectiveness of the maintenance actions, resulting in lower development and maintenance costs for the operating firm. Artificial neural networks and moving means were used to calculate the degradation indicators, based on the remainders in the model. The models were developed from operating data from fourteen wind turbines monitored over several years, and applied to the detection of faults in the bearings on the non-drive end of the generator. The use of generic models may not be recommendable for detecting faults in all cases, and the suitability will depend greatly on the context of the methodology developed to detect each type of fault, according to the element causing the fault and the fault mode, since each methodology requires a greater or lesser degree of precision in the model.

In the residential sector, biomass offers great potential to achieve the goals of the Europe 2020 strategy for climate and energy. With their policies, the different countries of the EU encourage actions in building stock such as the replacement of boilers with more efficient boilers and a greater use of renewable energy. This article explores the substitution of central fossil fuel boilers (heating oil, liquefied petroleum gas, and natural gas) with central biomass boilers to cover all heating and domestic hot water needs in multi-family buildings in Spain. Typical buildings from five cities located in each different climate zone of peninsular winter were chosen for this study. A thorough energy, environmental, and economic analysis is conducted. A reduction by as much as 93% in primary non-renewable energy consumption can be achieved, and CO2 emissions can decrease as much as 94%, resulting in better and higher energy performance certificate ratings. Despite the required investment, savings in all cases studied are achieved. The savings are greater with the increasing severity of winter weather, with a substantial reduction in energy costs.

The construction industry generates a considerable amount of waste. Faced with this undesirable situation, the ready-mix concrete sector, in particular, has invested energy and resources into reusing its own waste in its production process as it works towards the goal of more sustainable construction. This study examines the feasibility of incorporating two types of concrete waste, which currently end up in landfill, into the production process of ready-mix concrete: the waste generated during the initial production stage (ready-mix concrete waste), and waste created when demolition waste is treated to obtain artificial aggregate. The first phase of the study’s methodology corroborates the suitability of the recycled aggregate through characterization tests. After this phase, the impact of incorporating different percentages of recycled coarse aggregate is evaluated by examining the performance of the produced concrete. The replacement rate varied between 15% and 50%. The results indicate that recycled aggregates are, indeed, suitable to be incorporated into ready-mix concrete production. The impact on the final product’s performance is different for the two cases examined herein. Incorporating aggregates from generic concrete blocks led to a 20% decrease in the produced concrete’s strength performance. On the other hand, using recycled aggregates made from the demolition waste led to a smaller decrease in the concrete’s performance: about 8%. The results indicate that with adequate management and prior treatment, the waste from these plants can be re-incorporated into their production processes. If concrete waste is re-used, concrete production, in general, becomes more sustainable for two reasons: less waste ends up as landfill and the consumption of natural aggregates is also reduced.

We have studied decompression processes when pressure changes that take place, in blood and tissues using a technical numerical based in electrical analogy of the parameters that involved in the problem. The particular problem analyzed is the behavior dynamics of the extravascular bubbles formed in the intercellular cavities of a hypothetical tissue undergoing decompression. Numerical solutions are given for a system of equations to simulate gas exchanges of bubbles after decompression, with particular attention paid to the effect of bubble size, nitrogen tension, nitrogen diffusivity in the intercellular fluid and in the tissue cell layer in a radial direction, nitrogen solubility, ambient pressure and specific blood flow through the tissue over the different molar diffusion fluxes of nitrogen per time unit (through the bubble surface, between the intercellular fluid layer and blood and between the intercellular fluid layer and the tissue cell layer). The system of nonlinear equations is solved using the Network Simulation Method, where the electric analogy is applied to convert these equations into a network-electrical model, and a computer code (electric circuit simulator, Pspice). In this paper, numerical results new (together to a network model improved with interdisciplinary electrical analogies) are provided.
