This post focuses on the preliminary results of an analysis of differences between the market valuation of residential units conducted by experts and an automated program in the Czech Republic, specifically within the Brno-město district. So far, 40 apartments have been analyzed across various categories of floor area, layout, cadastral location, construction-technical condition, and other factors. The preliminary results showed a high correlation between the two methods (r = 0.963); however, significant differences were identified in certain segments, particularly in new constructions, apartments before renovation, and in varying floor areas. The resulting study may provide valuable insights for users of automated valuation tools.

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.

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.

The article largely copies the fourth chapter of the book Transport infrastructure management in context, which was recently published by VŠLG o.p.s. in Přerov. The entire book captures the links between the construction of transport infrastructure, its management and traffic operations in a unique way. All mentioned pillars of the book are described in an economic context with a focus on many information contexts.

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 article deals with various possibilities and research concepts of controlling heat pumps operating in heating systems. It also presents methods for controlling the thermal performance of heating systems with heat pumps and concludes with recommendations for the most suitable solution.

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.

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.

Mobile laser scanning (MLS) is currently commonly used in many surveying applications. The refinement of MLS point clouds is usually done by increasing the number of control points (CP) equally distributed within the mapped area. The accuracy of point clouds can also be improved by multiple passes of the mobile mapping system (MMS). This paper deals with the proposal of a suitable procedure by which it would be possible to remove local deformations of MLS point clouds. The proposed approach is based on the comparison of point clouds from multiple MMS passes. Additional CPs are then added to the places where the more significant differences between the point clouds.

The paper describes special types of fiber optic point sensors based on FBG (Fiber Bragg Grating) and FP (Fabry-Perót) structures. First part of the paper deals with principle of FBG and FP and their exposition. Next part is focused on different types of FBG and FP sensors and principle of interrogation units. Finally practical examples of use are listed.

The paper deals with special types of sensors that use optical fibers to measure various non-electrical quantities. The introduction describes the principle of light transmission in optical fibers and their applications. Main part is focused on fiber-optic sensors and their dividing. Special attention is paid to the distribution sensory systems and their practical application.

The article is intended for all clients (contracting authorities) who would like to choose a quality BIM contractor for their future project. It is based on the experience of implemented tenders (small-scale public contracts) and procurement procedures pursuant to Act No. 134/2016 Coll. on Public Procurement, as amended (“PP”). The article is an introduction to the system of qualitatively oriented selection of the BIM model contractor and related outputs – i.e. 2D drawing, quantity take-off, etc. This article applies to the Czech law.

The article deals with an acceptability assessment of a building extension from the point of view of daylighting in the case when daylighting of a neighbouring building is obstructed not only by the extended building but also by balcony and wing belonging to the neighbouring building. The results are confronted with the provisions of the Czech Standard ČSN 73 0580-1 and the Prague Building Regulations.

In this article, we focus on fundamental element of primary protection – detection devices for registering the rise of hazardous concentrations of gases and vapors. We have chosen and described for each type of device and kind of detected gas basic tests that are necessary for ensuring their correct and reliable function.
