The article focuses on the issue of real estate prices, specifically on the influence of the intangible factor neighbourhood and good address on the price of apartments and the price of houses. For the purposes of this article, intangible factors are defined as factors based on the location of the property or its surroundings, not the property itself. Tangible factors, on the other hand, include characteristics related to the size of the apartment or house and land, their design, condition, etc. The identification of relevant factors was based on a search of professional publications, and on the results of previously conducted research and sociological studies related to housing in Brno. The archive of expert opinions of the Institute of Forensic Engineering was also an inspiring source of data. The analysis also included publicly available advertisements for flats and houses, the purpose of which was to find out what features advertisers consider essential when describing real estate. The area of interest is the city of Brno. The final databases include sales of 346 apartments and 147 houses, and twelve intangible factors were evaluated. The analysis also includes tangible factors that were selected to adequately characterize the apartments and houses. The data were processed using two separate multivariate linear regression models with the least squares (OLS) method of estimating the regression parameters to describe the dependence of price on the explanatory variables (referred to as factors in this paper). Based on the analysis of the data obtained and their comparison with the regression model, the hypothesis that the observed factor is statistically significant for the price of flats and the price of houses at the chosen level of significance was confirmed. The hypothesis that this factor explains at least 5% of the price was confirmed only for detached houses.

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.

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.
