    Comparison of Properties Currently Offered on the Real Estate Market and Their Problems
    (Vysoké učení technické v Brně,Fakulta stavební, 2024-05-07) Malečková, Kateřina
    The current real estate market has experienced a major boom in recent years. The prices of real estate for housing have increased by several percentage points, and own housing is thus becoming less and less attainable for the general population. What has not disappeared from the market, however, are the problems that appear in housing units. The work deals with the survey of the offered units, revealing certain shortcomings and opens the topic where friction arises between the participants.

    Assessing the Environmental Consequences of Phosphate Emissions in Civil Engineering Projects and Their Inclusion in the Lifecycle Costs of Buildings
    (Vysoké učení technické v Brně,Fakulta stavební, 2024-05-07) Federla, Jakub
    Eutrophication, characterized by rising levels of nitrogen and phosphorus, poses a significant risk to biodiversity. In civil engineering, the contribution of phosphate emissions to this process has been insufficiently addressed and requires detailed examination. This study evaluates both the environmental and economic impacts of phosphate emissions in civil engineering, with a focus on their integration into the lifecycle costs of buildings. Detailed analysis of 17 residential buildings in the South Moravian Region has quantified environmental harm, establishing an economic cost of 5000 €/t for PO43-. Environmental damage caused by phosphate emissions was monitored throughout the construction and operational phases of the residential buildings. The research reveals that the ratio of annual operating costs to external societal costs varies from 1% to 11%. Furthermore, the research reveals that annual negative externalities per square metre due to phosphate emissions fluctuated between 4.99 €/m² and 0.19 €/m². These higher externalities also correlate with increased annual operating costs per square metre. Variations were primarily attributed to the characteristics of the building envelope, construction materials, and energy sources. These findings underscore the need for incorporating ecological costs into fiscal planning, highlighting the importance of sustainable construction practices in mitigating environmental impacts.

    Container Construction - Identification Cost and Time Savings
    (Vysoké učení technické v Brně,Fakulta stavební, 2024-05-07) 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.

    Building Passportization and Information Model of the Faculty of Civil Engineering in Brno
    (Vysoké učení technické v Brně,Fakulta stavební, 2024-05-07) Navrátilová, Vladimíra; Sudakova, Katsiaryna
    This article describes the process of building passportization and the subsequent application of an information model for the Faculty of Civil Engineering in Brno. Given the high probability that the building documentation for these structures is outdated, updating the information becomes essential for future maintenance, renovation, and grant applications. The purpose of the article is to provide a description of the procedure for building passportization based on laser scanning technology and showcase the results of the scanning process of Building Z.

    Current Problems in 2D Numerical Modelling of Water Flow in the River Channels
    (Vysoké učení technické v Brně,Fakulta stavební, 2024-05-07) Grmelová, Eliška; Skokan, Jiří; Juriga, Jan; Chrástová, Veronika; Pospíšilík, Šimon
    Currently, the use of two-dimensional numerical models in modelling water flow in river channels and floodplains is quite common. The quality of hydraulic calculation results is influenced by the number of input parameters. However, crucial in this context is primarily the availability of calibration data. Commonly used data from historical flood records are often burdened with significant uncertainties and, in many cases, are completely lacking. One option to ensure suitable calibration data is to measure flow rates and velocity fields in selected calibration profiles, e.g., using the ADCP method (Acoustic Doppler Current Profiler). The presented article showcases the authors' experiences with the calibration of a 2D numerical model applied to a real location, specifically using the mentioned method. The focus of the calibration lies mainly in the values of Manning’s roughness coefficients and parameters of turbulent models. The conclusion of the article includes a discussion of the results and recommendations for further research directions in the field, which appear promising for practical applications.
