The authors main idea is to build energy plus buildings by means of architectural processes to design passive houses according to the Darmstadt Standard with additional equipment powered by renewable energy. The article presents a comparative financial analysis of passive house buildings with an additional source of power to charge electric cars in Poland and the United States. The analysis is based on market data while also taking into consideration inflation and increases in energy costs. The methodology is based on the calculations required by USA banks for obtaining credit. The emphasis is also on the distinction between commonly used term passive house and the term passive house in accordance with the Darmstadt Standard. The authors are introducing a new terminology to define buildings wrongly named as “passive”. Now Authors will name them Pseudo-Passive Buildings. The research shows that it is profitable to construct nearly zero-energy buildings with photovoltaic installation and the discounted rate on return of investment does not exceed the mortgage length.

Purpose: The article presents the issues of metallurgist skills in the conditions of implementing the key technologies of Industry 4.0. The purpose of the paper was to propose a skills framework for a metallurgist in the context of Industry 4.0. Design/methodology/approach: The paper consists of an introduction and two substantive parts. The first part deals with the role of the human factor in Industry 4.0. The second part is about the skills of a metallurgist (the general framework of skills 4.0) in the transformation of metallurgical enterprises to Industry 4.0. The paper is part of the current research on skills of operators in Industry 4.0. The study uses a qualitative descriptive method referring to a critical analysis of literature about skills of the future. The article briefly reviews selected theoretical approaches to the operator-technology skills in the reality of Industry 4.0. Findings: The main result of the analysis was to bring closer the current, yet poorly scientifically recognised research about the place of human factor in the Industry 4.0 together with the structure of skills for the restructured employment in the steel industry. Research limitations/implications: In the conditions of the fourth industrial revolution and strong popularisation of the concept of Industry 4.0, enterprises must be able to reorganize human resources (HR). A new package of knowledge, new skills of employees are needed to perform tasks efficiently and to cooperate with new technological solutions of production and control and monitoring systems of manufacturing and service processes. The topic about human factor (HF) in Industry 4.0 is very actual and it will be developed according to wider and wider implementation of new (smarter) technologies in enterprises. Practical implications: Presented framework of human skills can be used to improve the skills profile of a metallurgist 4.0 (a worker in smarter steel mill). Social implications: In developing of new skills of employees in smart steelworks, besides steel mills, is needed an educational ecosystem, that joins different educational and science organizations. Originality/value: Reorganization of employment in Industry 4.0 is a new research field but very actual in the realized transformation process of enterprises. The paper is a form of introduction to discussion about new skills of operators in smart production.

Professional burnout is one of the significant factors affecting the productivity of the workforce. This has become more common during the COVID-19 pandemic due to the decrease in the psychological safety of employees. Working from home can also negatively affect work-life balance, leading to burnout. Undetected and untreated burnout leads to a decrease in worker productivity and eventually depression and other psychological problems. It is important to create and monitor working conditions to prevent professional burnout. Preventing burnout is always easier to achieve than treating the damaging symptoms. This paper will examine the factors contributing to professional burnout as well as some strategies for mitigating professional burnout. The article identifies the factors of occupational burnout after the COVID 19 pandemic based on the experiences of employees from Poland and the USA. The aim of the work is to indicate the first results of research in the field of occupational burnout, which are conducted on the basis of surveys. The questionnaire summary was prepared according to the model of research on burnout in relation to the pandemic situation. The presented results concern research for both production and service companies. And they are the basis for recognizing the factors responsible for occupational burnout for these employees.

Wypalenie zawodowe jest jednym z istotnych czynników wpływających na produktywność siły roboczej. Pojęcie to stało się bardziej powszechne ze względu na czas pandemii COVID-19, co miało bezpośredni związek ze spadkiem bezpieczeństwa psychicznego pracowników. Praca w domu może również negatywnie wpływać na równowagę między życiem zawodowym a prywatnym, co stanowi podstawowy czynnik prowadzący do wypalenia zawodowego. Niewykryte i nieleczone wypalenie prowadzi do spadku produktywności pracowników, a ostatecznie do depresji i innych problemów psychologicznych. Ważne jest tworzenie i monitorowanie warunków pracy, aby zapobiec wypaleniu zawodowemu. Zapobieganie wypaleniu jest zawsze łatwiejsze do realizacji niż leczenie szkodliwych objawów. W niniejszym artykule zostaną zbadane czynniki przyczyniające się do wypalenia zawodowego, a także niektóre strategie łagodzenia wypalenia zawodowego. W artykule dokonano identyfikacji czynników wypalenia zawodowego po pandemii COVID 19 na bazie doświadczeń pracowników z Polski i USA.
