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.

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.

Stricter ENB criteria and efforts to enforce a comprehensive view, not only the energy needs associated with housing, but also the place of residence, mode of transport, etc. show that the current situation is not systematically resolved. Meeting the new criteria in existing buildings, many of which have not even undergone basic insulation, will be very challenging, albeit necessary.

This article deals with valuation using BIM. The aim of this article is to appraise the construction using the BIM model in cost approach. The article deals with the description of BIM implementation and the need for BIM in construction. It contains a description of valuation methods, including the valuation of selected structures by individual methods. The individual methods are compared with the cost approach using RTS BIM.

Increasing or decreasing the heat factor of the heat pump does not reduce or increase the energy consumption in direct proportion, as the specific example shows. Instructions are also provided on how to evaluate the advantage of heat pumps with different heating factors.

The construction industry is the primary source of environmental impacts, especially the carbon footprint. Life cycle assessment (LCA) as an analytical method is used for quantifying the environmental impact of the investigated residential building. Life cycle costs (LCC) from the point of view of the circular economy create an economic model prioritizing reuse and recycling. The aim of this paper is to assess the residential building in terms of carbon footprint, using LCA analysis and circular economy, using LCC analysis. The residential building emits 1 756 tons of CO_2e , which represents 41.35 kg CO_2e/m²/year. The total estimated life cycle cost of the building in nominal terms is 1 694 699.61 €. This is the average total life cycle cost of 1 995.21 €/m².

The article deals with the principles of calculating the monthly method of supplied energy for heating. Describes in a clear form the individual mechanisms of calculation according to the relevant standards. It is designed for the needs of energy specialists and the professional public.

The article deals with the principles of monthly calculation of heat demand for heating and cold for cooling according to ČSN EN ISO 52 016-1. The article clearly presents the individual calculation mechanisms for the needs of energy specialists and the professional public.

The assessment of the energy performance of buildings depends on a large number of calculations, which must comply with the applicable legislation. The article presents the related structure of legal regulations, including standards and their brief characteristics.
