Use of BIM Model in the Design of the Renovation of Historic Buildings
Hrubovčáková, Andrea ; Mésároš, Peter ; Kozlovská, Mária ; Spišáková, Marcela
The article explores the practical application of Building Information Modelling (BIM) in renovating historical buildings, focusing on the digitalization process and the integration of fourth and fifth dimensions into the information model. It addresses challenges encountered when working with irregularly shaped buildings lacking preserved project documentation. Additionally, it examines the advantages and disadvantages of linking 3D elements with time and cost considerations. The authors present a methodology, a sequential approach tailored for BIM model utilization in historic building restoration, which was specifically validated through a case study of a historic church building in Rudník village. The methodology proposes a comprehensive framework applicable to the restoration of various historical buildings. The article contributes a generally applicable methodology for leveraging BIM models in historic building restoration, facilitating design and implementation processes across diverse historical contexts.

A Comparison of the 2PB TR and the IT CY Methods for Determining Asphalt Mixture Stiffness
Pospíšil, Jiří ; Valentin, Jan
In the Czech Republic, an intensive preparation of the construction of high-speed lines according to the principles adopted from France has currently been underway. Its substructure is among others to be made of a layer of asphalt concrete. However, the stiffness requirements of such an asphalt mixture cannot simply be taken from the French standards because in the Czech Republic, a different type of test methods for its determination is more commonly used. This paper describes an experimental study that compares the results of the asphalt mixture stiffness determined by the 2PBTR method used in France and the ITCY method which is frequently used in the Czech Republic (as well as in the United Kingdom). As part of the study evaluation, a mutual correlation between the individual methods is found for the results.

Energy Balance of Smart Ventilated Facade
Salajka, Radek
This article explains the function and basic energy balance for a smart facade system that is being researched at Brno University of Technology. This system is an upgrade to an already well-known ventilated facade. The upgrade is mainly presented by efficient control over built-in shut-off dampers inside the ventilated gap. The main goal is to reduce the energy consumption of buildings and create a healthy and comfortable indoor thermal microclimate in a much more ecological way. Numerical calculations are being used to present the energy use of a given facade in comparison with other conventional facade systems on the same building with identical boundary conditions. FSVM software which provides these calculations has been developed by the same research team. It can calculate the energy balance of conventional facades, ETICS and prototype of smart facades as well. This article presents ongoing research and results of the simulation of the heat flow of these three main facade systems throughout the year. Significant variables for facade heat flow calculations are weather and outdoor boundary conditions. They are used in this article as conditions for the Czech Republic which has a mild climate and four different seasons of the year.

Additive Technologies in Construction: Shifting the Paradigm of Building
Vaněk, Vojtěch ; Chomová, Štěpánka ; Pěnčík, Jan
Additive manufacturing is gaining importance in the building construction industry. With 3D printers for concrete or other materials, there have been significant advances in the material properties and technical excellence of the printed structures, which has enabled their huge expansion in the construction market. If properly embraced, additive manufacturing in the construction industry can bring about fundamental changes in structural design, crating safer, more efficient, economical, environmentally friendly and aesthetically attractive building elements and structures. Another application in the construction industry is in space construction. Here it has a major role in the use of autonomous site control on distant planes, which can be first tested, used and developed on Earth.

Container Construction - Identification Cost and Time Savings
Tejgi, Michal
Construction from containers can be more efficient than construction from conventional building materials in a number of suitable applications. From an investor’s point of view, the cost and speed of construction are important parameters, while from the societal point of view, it is environmentally friendly since it recycles original shipping containers. The core of this article is a case study of container construction of a primary school in Slovakia. The case study presents life cycle costs which are compared and contrasted with conventional construction. The aim is to compare investment construction costs. Finally, the results are compared with international studies on the topic of the life cycle of modular container buildings, project investment and renewability of this type of construction.

Open Data and Transport Modelling
Grishchuk, Dmitrii
Computer modelling has become one of the main methods of predicting the behaviour of traffic and passenger flows within small areas, cities, or entire regions. Sometimes the lack of data, either open or proprietary, or the lack of knowledge of where to find it and how to prepare it, is an obstacle to the development of a traffic model.
In this paper, the author has chosen to focus on finding and processing the freely available data on the population, infrastructure, facilities characteristics and placement for developing traffic models in any locality in the Czech Republic, regardless of size. The format of the processed data is chosen in such a way that it can be used for other analytical purposes.

Design and Implementation of the Geographical Information System of Zoo in Bratislava
Yakshin, Nikita ; Ďuračiová, Renata
Creating a Geographic Information System (GIS) is a complex, step-by-step process that involves requirements analysis, creating the system's architecture, data acquisition, and implementation. This project outlines the development of a user-friendly GIS, using Bratislava ZOO as a case study. The paper describes the process of creating a GIS from formulating tasks to full practical implementation. The result is a website with four geoinformation modules: engineering networks, infrastructure, visitor app, greenery, and a file library. This project can serve as a reference for similar spatial object management systems in parks and other areas.

Local Modelling of the Fractal Dimension on Digital Elevation Models
Ič, Tomáš
This study uses the box-counting method for local computation of the fractal dimension on a digital elevation model. The local method offers more detailed vertical ruggedness data than the global approach, providing deeper insight into surface structure. The work introduces an innovative local approach to determine the fractal dimension of surfaces and tests it on selected data samples. This work presents an effective geoscientific tool with potential cross-industry applications.
