This article addresses the transfer of data from a BIM model to Building Energy Modeling (BEM) environments using the gbXML format. A case study of a two-storey family house with a flat green roof is used to analyze the workflow, including data export from a BIM tool via a dedicated plugin and subsequent processing in external software provided by BIMTWIN. The modified gbXML model is then imported into energy assessment tools (e.g., DEKSOFT). The focus is on data quality and consistency, which often suffer from issues related to geometry, material properties, and the definition of constructions and openings. The model includes realistic construction assemblies and different approaches to modeling openings. The aim is to evaluate the usability of gbXML and identify critical points in this workflow.

Radiation emergency events represent a specific type of crisis that requires targeted and effective crisis management responses. Effective management of such situations requires rapid threat identification, coordinated response between government agencies, emergency services, and international organizations. This article focuses on the key factors of crisis management in the case of a radiation emergency, including prevention, public protection, and communication with the media and the public. Additionally, the role of international cooperation in managing cross-border radiation events is examined. By analysing past radiation emergencies and the lessons learned, this paper provides insights into improving crisis management systems and enhancing resilience in the face of such high-stakes incidents.

This article explores the potential for rental housing in existing single-family home areas in the suburbs of Prague through soft densification. It opens a discussion on the possible incremental transformation of these unsustainable locations, responding to their circumstances, including the current housing affordability crisis and demographic aging of the population. The aim of the research is to quantify the spatial reserves in the built-up areas of municipalities that would allow for the development of housing units without the need to occupy new land. Through GIS analysis, more than 31,500 plots in 40 municipalities strongly affected by suburbanization were examined. The results show significant spatial reserves for the creation of additional housing units, either on the plots or inside family houses within their spatial reserves. The study confirms that the adaptation of the existing stock of family houses represents a significant and yet untapped source of housing units,that would lead to increasing population density, supporting social sustainability, and more efficient use of infrastructure in satellite municipalities.

The article focuses on the safe operation of Mobile Elevating Work Platforms (MEWPs) in compliance with current Czech legislation and technical standards. It highlights common mistakes observed in practice, the responsibilities of operators and employers, requirements for documentation, inspections, and operator training. Special attention is given to the use of personal fall protection equipment, the platform work system, and legal obligations under Act No. 250/2021 Coll., Government Decree No. 193/2022 Coll., Government Decree No. 362/2005 Coll., and EN 280. The text provides practical recommendations to ensure workplace safety and legal compliance for MEWP operators.

In this two-part series, we focus on the advanced standard for communication between automation devices in buildings. The previous part described the supported networks and object model. This second and final part describes the service system and tools for ensuring the interoperability of devices from different manufacturers.

Building Automation and Control network (BACnet) is network protocol specifically designed for automation and control of technologies in buildings. Typical applications include heating, ventilation, air conditioning, lighting, access control and fire detection. It provides standardized framework for organizing and sharing information between networked control devices [1, 2]. Interoperability is provided through object model of information items and their properties and associated services. Flexibility is provided by a range of supported networking options from serial line to Ethernet and internet connection. However, BACnet does not guarantee interchangeability of products from various vendors and every controller or other product may require vendor-specific programming and configuration tools.

Pre-demolition audits help identify materials suitable for reuse or recycling, thereby reducing the volume of construction and demolition waste and supporting the principles of the circular economy. The article presents the legal framework, audit methodology, and the environmental and economic benefits of such audits. It also includes current insights and practical examples from the European project CIRC-BOOST (Horizon Europe), which tests and implements circular solutions in construction through pilot projects in five countries.

The article “Safety of Rack Systems in Warehouses” deals with key aspects of safety when using rack systems in warehouses. It emphasizes the importance of regular inspections and maintenance of rack structures to prevent accidents and injuries. Furthermore, it addresses legislative requirements and standards that must be followed to ensure the safety of workers and stored materials. The article also provides practical advice and recommendations for the proper use of rack systems, including correct loading and organization of stored items.

This article addresses a crucial aspect of fire safety in buildings – the accessibility and unobstructed condition of escape routes. Based on real-world examples, it highlights severe deficiencies such as incorrectly mounted fire doors, missing door closers, and the placement of combustible furniture in protected escape routes. The text explains the applicable legal and technical requirements (e.g., Decrees No. 23/2008 Coll., 202/1999 Coll., Government Regulation No. 101/2005 Coll., and ČSN 73 0835) and provides practical recommendations for facility managers, building administrators, and fire safety professionals. The aim is to reduce evacuation risks and ensure compliance with fire safety legislation.

Creating a good BIM model is a long and challenging process for HVAC designers. Various plugins (addons) for BIM programs are currently being developed and upgraded to try to make designers work easier and eliminate duplication of effort. This paper examines the design of a buildings drainage system in Autodesk Revit BIM program, which has been extended with the MagiCad 2024 plugin.

This article presents a simulation analysis conducted at the Institute of Environmental Engineering at CTU, as part of the international exercise IEA EBC Annex 82. The aim of the joint exercise, which involved more than ten international research teams from different sectors, was to test and compare different approaches towards achieving energy flexibility in buildings on the basis of a unified exercise assignment. The Czech team based its study on a comprehensive simulation of the energy behaviour of buildings, including a detailed numerical model of the heating, hot water preparation, cooling and ventilation systems. The model was used to study the building potential for providing energy flexibility and future responsibilities of building operators in the context of smart energy grids.

This paper focuses on fire safety solutions for warehouses according to ČSN 73 0845. For comparison, the requirements set by the legislation in Portugal and Canada are analysed, as well as the requirements set by the NFPA (The National Fire Protection Association). The different approaches are compared and the most important differences are mentioned, especially in relation to current trends in warehousing. Finally, a software tool created in the Python programming language called “Warehouse Operations Group” is introduced. This tool is used to classify the fire compartment of a warehouse into a group of warehouse operations according to the method set out in Annex A of ČSN 73 0845. The process of determination simplifies and eliminates any errors that may enter into the calculation.
