Energy poverty is a problem that affects all member states of the European Union to a varying degree, including Poland, where about 9% of the population is at risk of energy poverty. The article aims to show the changes in energy poverty in Poland in 2010–2018. The specific goal, however, is to evaluate government measures aimed at reducing energy poverty through investments based on renewable energy sources. To present changes in the level of energy poverty in 2010–2018, the authors proposed a new synthetic measure that unifies several different measures used by researchers and allows for a comprehensive assessment of this phenomenon. The conducted research showed that in 2010–2018 there was a slow but visible decrease in the level of energy poverty in Poland. In addition, the article indicates investments in renewable energy sources that may have a positive impact on reducing the scale of energy poverty in Poland. The programs implemented with national and EU public funds, which finance investments in renewable energy sources in Poland, are also presented.

Purpose The purpose of this study is to design a zero-energy home, which is known to be capable of balancing its own energy production and consumption close to zero. Development of low-energy homes and zero-net energy houses (ZEHs) is vital to move toward energy efficiency and sustainability in the built environment. To achieve zero or low energy targets in homes, it is essential to use the design process that minimizes the need for active mechanical systems. Design/methodology/approach The methodology discussed in this paper consists of an interfacing building information modeling (BIM) tool and a simulation software to determine the potential influence of phase change materials on designing zero-net energy homes. Findings BIM plays a key role in advancing methods for architects and designers to communicate through a common software platform, analyze energy performance through all stages of the design and construction process and make decisions for improving energy efficiency in the built environment. Originality/value This paper reviews the literature relevant to the role of BIM in helping energy simulation for the performance of residential homes to more advanced levels and in modeling the integrated design process of ZEHs.

Abstract This paper provides an empirical analysis of deploying renewables in Africa's five most populous countries for 2001-2019. It analyzed these factors to see how they impact deploying renewables by employing panel data using the pooled ordinary least squared(OLS) at frim level analysis to increase energy security and to reduce energy poverty. After the analysis, we proved that access to clean fuels and technologies for cooking needs the study countries to deploy renewables as most Africans cook with polluting fuels having detrimental health implications. The analyses further revealed that these countries generate a chunk of their electricity from fossil fuel sources, making it imperative to jettison fossil fuels and embrace renewables cheaper and environmentally friendly. The analysis also showed that the Quality of regulation in a country is vitally important to scaling up renewables in the study countries since the right policy tools underpin the transition. Furthermore, the lack of Electrification is important to developing renewal energy sources in the study countries. Sub-Saharan Africa has about nearly 600 million people not having access to electricity. Thus deploying renewables will bridge the access gap. Cleaner energies will be the panacea to the study countries’ energy insecurity situation and bridge the access gap. The study countries have the technical and theoretical potential for all the renewable energies needed to ensure sustainable consumption. What is needed is to institute cornerstone financial policy de-risking instruments to crowd in private capital since the renewables sector is perceived as a high-risk area.

Special Case

An agent- based model of social dynamics is introduced using a deformable fitness landscape, and it is shown that in certain clearly specifiable situations, strategies that are different from utility maximization outperform utility maximizers. Simulation results are presented and intuitive interpretations of the results provided. The situations considered occur when individuals' actions affect the outcomes for other agents and endogenous effects are dominant. The Tragedy of the Commons is merely a special case of this. Arguments are given that constraints are to be encouraged in some circumstances. The appropriate role of constraints in various types of society is assessed and their use justified in identifiable types of situations.

Abstract LC refining of mechanical pulps has proven to save energy in the production of TMP pulps. However, the specific role of LC refining as part of a TMP system has not been thoroughly studied since it is difficult to conceive any particular system at industrial-scales and impractical at pilot-scales. In this study, pressure screening and LC refining models that describe fibre length distributions, together with correlations to predict refining power were used to model three basic refining systems. From the simulation results, the impact of important variables such as reject ratio, refiner gap and refining net-power was studied. Performance curves of length-weighed average fibre length were generated from simulation results and were used to assess each system behaviour and also to make comparisons between systems. Data from an industrial scale TMP mill sub-system was gathered and compared to simulation results showing relative errors between 0–18 % on the predicted variables.

AbstractIn this paper, we study the role of inlet gas temperature and jet to bed cross-section ratio on hydrodynamics and circulation patterns of particles in a spout-fluid bed. The system is modeled using CFD-TFM approach based on Eulerian-Eulerian method. Simulation results are validated by experimental data measured by (Link 2008. “PEPT and Discrete Particle Simulation Study of Spout-fluid Bed Regimes.” Aiche Journal 54 (5): 1189–202). First, the sensitivity analysis of simulation results versus the most significant parameters are conducted to find the optimum values for each parameter. Subsequently, the role of inlet gas temperature and cross-section ratios are studied in detail. The simulation results clearly demonstrate that increasing the inlet gas temperature raises particles’ velocity in the bed and affects the circulation pattern in annulus region. Additionally, it is shown that higher gas temperature leads to existence of hot spots in the annulus region. In case of jet to bed cross-section ratio, using larger ratios results in higher velocities and lower pressure drop along the bed.

Simulation Results

We demonstrate a design method of focusing-control device, which consists of single metallic nano-slit surrounded with the grooves at the metal exit surface. According to the principle of the constructive interference, the grooves are positioned to scatter the SPPs to the radiation lights with desired phases. The role of SPPs in the focusing control is investigated, by applying the design method in the four different types of metal film. The simulation results indicate that the focusing effects are dependant on the types of metal film, the metal film which supports the SPPs with a long propagation length can form an apparent focus spot, and the reason is discussed.
