The present paper highlights a quantitative method to maximize energy efficiency based on the minimum energy consumption and maximum quality of life from consumption behaviors. Quality of life is expressed by utility, which is a Constant Elasticity of Substitution (CES) function of demands for composite goods, car trips and public transport trips. Individual energy consumption is estimated by the demand of goods and we applied this method to Nagasaki to evaluate energy efficiency. Our results showed that 28,154 kcal of energy is needed to support the life of one individual per day in Nagasaki. Furthermore, we found that 76% of energy was used for composite goods and 24% was used for mobility goods. To achieve maximum energy efficiency, our results highlight that energy should be reduced by increasing the consumption of composite goods and public transport trips, while simultaneously decreasing the consumption of car trips. Compared to residents in urban and suburban areas, individuals in Central Business Districts (CBD) were found to have higher energy efficiency. Findings in Nagasaki suggest three policy implications: First, eco-energy consumption patterns should be encouraged to decrease energy use, while maintaining quality of life. Second, mixed land use is attributed to increased energy efficiency. Lastly, the energy efficiency of mobility could be improved though increasing the attraction of public transport.

The article is devoted to assessment of quantitative and qualitative human capital reproduction in energy-efficient economy provided by research of correlation between dynamics of energy consumption and transformation of life quality. The purpose of the research is to assess the role of energy-efficient economy in shaping of the conditions for human capital reproduction as a way of investment into its qualitative development. To achieve this purpose transformation of traditional spheres of sustainable development together with the implementation of the energy-efficient economy approaches in terms of maintaining of quality of human capital are considered. We conduct a study comparing several dependencies: development of productive powers - increasing requirements for the quality of human capital; ensuring effective reproduction - improving the quality of life, improving the quality of life associated with the economic system; GDP – energy consumption; GDP - CO2 emissions. The object of the study is dynamics of indicators characterizing the above dependencies, a number of the countries – members of the OECD – having an expanded human capital reproduction. Examined countries demonstrate correlation between energy efficiency of economy and quality of human capital with rather a wide variability of chosen indicators. Results of the research may become a base for forecast of development of studied indicators and their factors.

The Quality of Life of Suburbanities: A Case Study of the Gdańsk Agglomeration The article explains the meaning of the concept of ‘quality of life’, placing emphasis on its subjective dimension. As the concept is more and more discussed in the literature, the author intends to examine the satisfaction within public spaces for which local government is responsible. According to research made in Canada it is worth measuring not only satisfaction as such but also the importance of its constituent dynamics. Therefore, a survey made in the suburbs of the Gdańsk agglomeration asked respondents about their satisfaction with public transport, roads, environment, etc., including questions about the relative importance of such issues. The combination of satisfaction and importance provide the overall quality of life. At the end of the paper the author considers if there is a chance to improve the quality of life through a brief analysis of local governments expenditure.

Abstract Introduction In Finland the employment rate of people with foreign origin backgrounds appear to be 10% lower than in general population (73.7%). Contradictory, higher levels of self-perceived quality of life (QOL) has been reported among the same population. This secondary data analysis aims to examine the association between level of employment and quality of life from the survey on work and well-being among people of foreign origin in Finland (UTH, 2014). Methods People of foreign foreign origin, living in Finland were included in statistical analysis (n = 2,987). Pearson Chi-squared (χ2) and likelihood ratio (LR) testing as well as logistic regression analysis were used to study the association between independent variable 'employment' and the dependent variable of 'quality of life'. Results Employment showed increased odds for 'good' QOL. However, when comparing the two gender groups, the odds of having 'good' QOL in employed men were higher (OR: 2.17 CI 2.11 - 2.24) compared to employed women (OR: 1.50 CI 1.45 - 1.53) respectively. When adjusted for sociodemographic and confounding factors, the levels of strength of the association between employment and quality of life remained. Conclusions Women with foreign origin backgrounds seem not to have equal benefits of employment and/or equal access to labour markets in Finland. Validation about barriers of entering the labour market in Finland are further needed. Policy implications and actions are needed to improve equal access and benefits of employment for better well-being for women with foreign origin backgrounds. Key messages Women with foreign origin backgrounds seem not to have equal benefits of employment and/or equal access to labour markets in Finland. Policy implications and actions are needed to improve equal access and benefits of employment for better well-being for women with foreign origin backgrounds.

Energy consumption in the world increases, so the measures in order to improve energy efficiency must be found. The aim of 2012/27/EU Energy Efficiency Directive targets is to decrease energy consumption for a final energy consumer by 1.5% every year, but there is no definition how these targets could be achieved by an individual member state. This article presents the analysis how these targets could be achieved by the means of individual heat metering by heat cost allocators for every flat thus decreasing an energy consumption for a final consumer. Statistical analysis of identical buildings with individual metering by heat cost allocators and without them is presented. Heat cost allocators do not decrease energy consumption by themselves, so this article presents a technical solution and a set of additional equipment, i.e. thermostatic valves, balance valves, hot water meters and remote data collection system that must be installed. The final results show that the targets of 2012/27/EU Energy Efficiency Directive in Lithuania can be reached, because the buildings with individual heat cost allocators consume about 20–30% less of heat energy. Pasaulyje energijos vartojimas auga, todėl turi būti rastos energetinio efektyvumo pagerinimo priemonės. 2012/27/ES Energijos Efektyvumo Direktyvos tikslas yra sumažinti galutinio energijos vartotojo energijos suvartojimą kasmet po 1,5 %, tačiau nėra nurodyta, kaip kiekviena valstybė narė šiuos tikslus galėtų įgyvendinti. Šis straipsnis pristato analizę, kaip šie tikslai galėtų būti pasiekti, kiekviename bute įrengiant individualios šilumos apskaitos šilumos daliklius, kad sumažėtų energijos vartojimas atskiruose butuose. Pateikta statistinė identiškų pastatų su šilumos dalikliais ir be jų analizė. Šiluminei energijai taupyti neužtenka vien tik šilumos daliklių, todėl straipsnyje pateiktas techninis sprendimas – būtinų įdiegti techninių priemonių paketas, kurį sudaro tokios priemonės: termostatiniai ventiliai, balansiniai ventiliai, karšto vandens skaitikliai, belaidė reguliaraus duomenų nuskaitymo sistema. Galutiniai analizės rezultatai rodo, kad 2012/27/ES Energijos Efektyvumo Direktyvos tikslai Lietuvoje gali būti pasiekti, nes pastatai su individualia šilumos apskaita ir įrengtais šilumos dalikliais vartoja apie 20–30 % mažiau šiluminės energijos nei pastatai be tokios apskaitos.

The Impact

Since the inception of microcredit programmes, various studies have been carried out to assess their impacts. Earlier studies seemed to highlight this on the participants’ income and consequently poverty. However, recent impact studies of microcredit programmes have been looking into participants’ quality of life. Thus, this study attempted to investigate the impact of Amanah Ikhtiar Malaysia’s microcredit programme on the participants’ quality of life and analyse the differences between the new and old participants. This study took on a different perspective by examining aspects of personal attitude, subjective norm, perceived behavioural control, as well as entrepreneurial intention and behaviour. In selecting the samples, a probability sampling (disproportionate stratified) technique was employed. The hypotheses were tested using cross-sectional data of 638 Amanah Ikhtiar Malaysia participants. The findings of the study showed that all the hypotheses were significant and supported, where there was significant influence between participants’ personal attitude and entrepreneurial intention, participants’ subjective norm and entrepreneurial intention, participants’ perceived behavioural control and entrepreneurial intention, participants’ perceived behavioural control and entrepreneurial behaviour, participants’ entrepreneurial intention and entrepreneurial behaviour, including participants’ entrepreneurial behaviour and participants’ quality of life. On the contrary, the findings of the study revealed no difference in the quality of life between new participants and old participants. This study may contribute to the policy implications of Amanah Ikhtiar Malaysia’s microcredit programme, especially in improving training and guidance.

The article analyzes domestic and international experience in the field of energy efficiency and energy security. Thus, it was important to adopt the Law of Ukraine "On the Energy Efficiency of Buildings", which introduced mandatory certification of buildings by energy consumption classes. The study of sources on the issues of effective energy consumption showed that issues related to improving the energy efficiency of buildings and structures are acquiring special relevance; the use of foreign models to improve the energy efficiency of the housing stock. Specific organizational and economic measures are highlighted that will help improve the energy efficiency of the national economy. The Swedish experience of using a modern cost model for the full period of operation ("General Concept") is studied, which aims to assess the economic results of investments in measures to improve the energy efficiency of the housing stock. The main principles of the modern cost model of the full operation period and the criteria for determining the number of necessary energy efficiency measures are considered. Analyzed "hard" (physical condition of the building) and "soft" (user behavior) measures that provide for the integrated energy efficiency of the building. The stages of the analysis according to the cost model of the full operation period are considered. The typical for Sweden ranges of the duration of energy efficient measures and the requirements for the internal rate of return, which depends on the general economic situation in the country and the terms of the loan, have been investigated.  Based on the results of the energy audit of the ten-story building selected for the study and taking into account the experience of Sweden, a number of measures to improve energy efficiency are proposed and a calculation is given to ensure the energy efficiency of a residential building in Ukraine. Based on the results obtained, it can be concluded that there is a positive trend in this implementation. With the integrated use of all measures that will even allow you to save more, you can significantly improve the energy efficiency of the existing housing stock in Ukraine.
