The article thoroughly describes the role of a corporate ecologist in complying with environmental regulations within businesses. In addition to traditional areas such as waste management, packaging materials, chemicals, and accident prevention, it now focuses on ESG reporting. It emphasizes trends towards sustainable waste management and the circular economy. The text analyzes strategies for waste prevention, trends, and innovations in their processing. Finally, it highlights the importance of education and awareness in this field.

IT systems in companies are often incompatible and their data communication is very complicated. A unified, integrated operating environment ensures real online communication not only of technological devices, but also technology for quality monitoring, systems for order planning, service and maintenance, as well as energy management.

The constantly evolving environment of industrial companies, influenced by the advent of new technologies, also affects maintenance. The aim of this paper is to present the possibility of managing maintenance with the help of an information system. Its functionalities allow the implementation of all strategies, i. e., in addition to corrective and planned maintenance, it also uses preventive diagnostic maintenance.

The resulting value of the heating factor of a combination of two heat pumps, in which the first heat pump is the heat source for the second heat pump, can be determined fairly easily in common technical application practice. The procedure and the resulting formula are given in the article.

The paper relates the results of efficiency tests of specific application methods of surface and air remediation in the indoor environment of buildings, the scope and supply of which have significantly expanded in connection with the ongoing SARS-CoV-2 epidemic. The tests were focused on the most frequently offered procedures, i.e. on the use of open and closed (air purifiers) sources of UV-C radiation, fumigation (use of biocides) and ozonation. Special attention is paid to fulfilling the wording of related EU laws and regulations and compliance with safety principles in the application of these procedures in the work and municipal environments. We also give examples of numerous problems and shortcomings in the application of these technologies.

This article focuses on common issues faced by owners and operators of buildings and technical equipment. Key themes include the lack of proper documentation, failure to meet legislative requirements, and frequent mistakes in safety procedures. The author thoroughly discusses various aspects, including missing documentation, insufficient authorizations and training, and non-compliance with safety standards. The article also emphasizes the importance of proper documentation management and compliance with current legislative requirements to ensure safe and efficient operation.

The paper presents the concept of maintenance engineering as understood in the new European standard EN 17666:2022 Maintenance - Maintenance engineering - Requirements. The standard introduces maintenance engineering as a discipline that uses competencies, methods, techniques and tools to develop and support maintenance to ensure that (maintenance) item is able to perform its required functions in a safe, sustainable and cost-effective manner throughout its life cycle.

The presented set of four communications deals with the risk management in favour of safety applied to the operation of pipelines. It respects current professional knowledge and presents it in the concept promoted by the UN, the European Union, the OECD and others. The fourth part contains a conclusion, characteristics of new aspects addressed by the professional sphere for practice and a list of used literature.

The presented set of four communications deals with the risk management in favour of safety applied to the operation of pipelines. It respects current professional knowledge and presents it in the concept promoted by the UN, the European Union, the OECD and others. The third part summarizes the findings on the checklist methodology and provides examples for pipelines.

The presented set of four communications deals with the risk management in favour of safety applied to the operation of pipelines. It respects current professional knowledge and presents it in the concept promoted by the UN, the European Union, the OECD and others. The second part summarizes the knowledge and principles of risk management and lists the sources of risks for the pipeline.

The presented set of four communications deals with the risk management in favour of safety applied to the operation of pipelines. It respects current professional knowledge and presents it in the concept promoted by the UN, the European Union, the OECD and others. The first part introduces terms used in engineering practice, which deals with risks and safety and introduces knowledge that is relevant to pipeline safety.

Modifications of a large number of older family houses to classification class E or class D energy efficiency can be implemented by measures on the side of the building envelope even without changes to heat sources, if this obligation is introduced. Roughly, it is expected after 2030.

Design engineering using standard objects brings new possibilities to water management design practice. Similar to CAD tools in the past, integrated engineering now represents the gateway to the world of digitization of water management units and can be understood as an effective pre-step before the introduction of BIM, enabling the creation of digital twins and operational optimization. These new procedures can open the gates of perception of the project and management of the whole in hitherto unknown levels. Due to emerging legislative and business trends in the Czech Republic, we can expect an increased demand for digitally processed projects in object architecture, enabling an interconnected approach to the creation and management of documentation in individual phases of the life cycle of a technological unit.

This paper discusses the feasibility of long-term monitoring using modern sensors and systems. New technologies are making long-term monitoring more accurate simpler and more successful. Currently there are many buildings that are monitored for a long time with its subsequent condition assessment, and thanks to the installed sensors and systems it has been possible to detect hidden and emerging defects and damages. Based on the current condition of the structure, it has been possible to carry out timely repairs or maintenance of the building which ultimately saves economic and time costs for the building, ensures safety and increases the life and durability of the building.
