The aim of the research is to obtain optimal ranges of thermal envelope for the desired energy classes, which will contribute to a more economical and rational approach to the design of buildings, as well as to prove that with the increase of thermal envelope there is an increase of the energy class. The model on which the research was formed and applied is a typical semi-detached house in Belgrade. By comparing the results of the reference family house, the framework parameters for the satisfaction of a certain energy class have been formed, based on the fulfillment of the energy efficiency requirements established by national regulations.

This article identifies and compares the housing preferences of seniors and pre-senior citizens in Poland. In addition, the attitude of residents of large cities in the Wielkopolskie Voivodeship towards senior citizens’ housing was determined. Surveys were conducted in the two largest cities of this region. The influence of the potential behaviors of this group of society on the development of housing was also examined. Results showed that differentiation of housing preferences was visible primarily when choosing the type of development and size of the dwelling. Seniors preferred smaller units in multi-family housing construction. Pre-senior citizens, on the other hand, were more likely to think about living in a single-family house. The location of a new dwelling was also important. Seniors, more often than people aged 50–59, chose a location in the city center. Pre-senior citizens, in contrast, more often decided to live in a rural area or outside the city center. Moreover, the attitude of seniors towards senior citizens’ housing is undecided, which may indicate that many people may change their housing preferences in the future and decide to move.

Energy efficiency of existing buildings is a concept to manage and restrain the growth in energy consumption and one of the crucial issues due to the magnitude of the sector. Educational buildings are in charge of about 15% of the total energy consumption of the non-residential building sector. However, not only operational but also embodied energy of a building should be reduced to get the overall benefits of energy efficiency, where, using energy efficient architectural measures and low emitting materials during every retrofit action can be a logical step. The majority of buildings in Turkey and EU was built earlier than the development of the energy efficiency in the construction sector, hence, without energy retrofit, consume an enormous amount of energy that can be averted significantly by the implementation of some even not advanced retrofit measures. Furthermore, demolishing of a building to construct a new one is not a rational approach concerning cost, time and environmental pollution. The study has been focused on the impact assessment of the various architectural scenarios of energy efficiency upgrading on the Life Cycle Energy Consumption (LCEC) and Life Cycle CO2 (LCCO2) emission. Within the scope of the study, a primary school building is selected to be analysed. Through analysis, the total embodied and operational energy use and CO2 emission regarding the life cycle phase of the building is quantitatively defined and investigated in the framework of life cycle inventory. The paper concentrates on the operation and embodied energy consumption arising from the application of a variety of measures on the building envelope. An educational building with low LCCO2 emissions and LCEC in Turkey is proposed. To exemplify the approach, contributions are applied to a case study in Istanbul as a representative school building. The primary energy consumption of the case study building is calculated with a dynamic simulation tool, EnergyPlus. Afterwards, a sort of architectural energy efficient measures is implemented in the envelope while the lighting and mechanical systems remain constant. The energy used in the production and transportation of materials, which are the significant parts of the embodied energy, are taken into account as well.

The Impact

One of the strategies of the European Green Deal is the increment of renewable integration in the civil sector and the mitigation of the impact of climate change. With a statistical and critical approach, the paper analyzes these aspects by means of a case study simulated in a cooling dominated climate. It consists of a single-family house representative of the 1980s Italian building stock. Starting from data monitored between 2015 and 2020, a weather file was built with different methodologies. The first objective was the evaluation of how the method for selecting the solar radiation influences the prevision of photovoltaic productivity. Then, a sensitivity analysis was developed, by means of modified weather files according to representative pathways defined by the Intergovernmental Panel on Climate Change Fifth Assessment Report. The results indicate that the climate changes will bring an increment of photovoltaic productivity while the heating energy need will be reduced until 45% (e.g., in March) and the cooling energy need will be more than double compared with the current conditions. The traditional efficiency measures are not resilient because the increase of the cooling demand could be not balanced. The maximization of installed photovoltaic power is a solution for increasing the resilience. Indeed, going from 3.3 kWp to 6.9 kWp for the worst emission scenario, in a typical summer month (e.g., August), the self-consumption increases until 33% meanwhile the imported electricity passes from 28% to 17%.

AbstractThe Republic of Serbia must make significant efforts to promote and exploit renewable energy sources and increase energy efficiency in all energy sectors to ensure energy security and economic competitiveness, reduce the negative impact on the environment from energy production and use, and contribute to global efforts to reduce greenhouse gases. Within the paper several issues of integration of recently realized CHP plant are introduced and discussed. Firstly, the legal and energy policy issues in the Republic of Serbia regarding connecting CHP to the grid are presented. The challenges and technical solutions for CHP connection to the grid, as well as power quality issues and the role of the CHP plant during the restoration of power supply during the maintenance of the substation and unplanned loss of high voltage supply, are presented and discussed. Finally, the impact of prospective massive integration of CHP on the energy balance and CO2 emission reduction in the province of Vojvodina in Serbia is investigated and discussed. Since it is the first CHP plant realized in Serbia, it is crucial that experience be shared to all potential stakeholders in the future energy efficiency projects.

Shared leadership and proactivity in the New Ways of Working Shared leadership and proactivity in the New Ways of Working Increasingly, employees are experiencing so-called New Ways of Working (NWW), facilitated by advanced ICT. They must deal with more autonomy and responsibilities in combination with flexibility in time and location of work. It has been argued that NWW combine well with novel leadership styles, such as shared leadership, although this relationship has not been studied before. Similarly, the expected consequences of NWW on proactivity of employees and teams requires academic investigation. This paper reports on a study on the impact of NWW implementation on shared leadership and the proactivity within SNS REAAL (a large banking and insurance company in the Netherlands). The case study is particularly interesting since NWW employees (N = 51) are compared with non-NWW employees (N = 77). The results confirm that NWW have a positive, significant relationship with team proactivity behaviour. In addition, the implementation of NWW can have an indirect impact on the individual proactivity of employees, which is only effective if team proactivity is promoted. Merely implementing NWW will not result in shared leadership. The findings suggest that NWW characteristics, such as an open feedback culture, more autonomy, and internal entrepreneurship, are most effective in the pursuit of proactivity and shared leadership.

This chapter discusses the influence individuals have in the ICT standards development process. The chapter draws upon ideas underlying the theory of the Social Shaping of Technology (SST). Looking through the SST lens, a number of non-technical factors that influence ICT standards development are identified. A literature review on the role of the individual in ICT standards setting and a case study of the IEEE 802.11 Working Group (WG) show that in a standards body's WG, the backgrounds, skills, attitudes, and behaviour of the individual WG members are crucially important factors. Yet, the case study also shows that in most cases employees tend to represent the ideas and goals of their respective employer. The chapter observes that the non-technical factors are ignored all too often in the literature. It argues that a better understanding of the impact and interplay of these factors, specifically including the skills and attitudes of the WG members, will have significant implications both theoretical and managerial.

Additional opinions—that is, dissenting opinions, separate opinions, and declarations—are, by definition, the primary institutional mechanism through which judges can express their individual views on a particular decision, as distinct from the judgment or decision proclaimed on behalf of the institution. Therefore, within the public sphere they are the principal institutional manifestation of the individual—and thus the individuality—of the judge. Consequently, for those who seek to understand the impact of certain personal characteristics upon how a judge discharges their professional functions and, in turn, the wider institutional and systemic implications of the participation of individuals bearing those characteristics, the study of additional opinions would seem a useful analytical enterprise. Using gender diversity at the International Court of Justice as a case study, the purpose of this chapter is twofold: first, to explain the relationship between diversity and additional opinions, and second, to explore the methodological potential, and challenges, that the study of additional opinions entails.
