Introduction and objective: Using the concepts of Ulrich’s theory of supportive design and Malkin’s healing environment, an eye tracking experiment was designed in order to measure respondents’ reactions while looking at visualisations of various interiors, with the aim of verifying...

In the presented paper, a study of bi-axial buckling of the laminated composite plate with mass variation through the cutout and additional mass is carried out using the improved shear deformation theory (ISDT). The ISDT mathematical model employs a cubic variation of thickness co-ordinates in the displacement field. A realistic parabolic distribution of transverse shear strains through the plate thickness is assumed and the use of shear correction factor is avoided. A C° finite element formulation of the mathematical model is developed to analyze the buckling behavior of laminated composite plate with cutout and additional mass. As no results based on ISDT for the considered problem of bi-axial buckling of the laminated composite plate with mass variation are available in the literature, the obtained results are validated with the data available for a laminated composite plate without cutout and additional mass. Novel results are obtained by varying geometry, boundary conditions and ply orientations.

Noticeable climate change in recent years is reducing the comfort of public spaces in the urban environment, and is becoming an element of urban policies. The adaptation to climate change requires the development of new design guidelines for the development of public spaces. The appropriate definition of development density, choice of building materials, technologies, planting species, and the used directions is a challenge that depends on local conditions. A representative public space located in the area of a multi-family housing estate built in the second half of the 20th century in Lublin (Poland) was selected for the study. The space has undergone redevelopment twice in the last 10 years. The aim of the study was to determine to what extent the executed and designed changes actually improve the thermal comfort of users. Quantitative and qualitative indicators of the successive phases of the investment were analyzed in the context of projected climate change. The simulation was developed using the ENVI-met version 5.0 software. As a result of the changes made, there has been an improvement in usability and comfort. Five simulations were carried out for the warmest day of the year for one of the public spaces in the city of Lublin. The sensation of PET thermal comfort was investigated for people aged 35 and 75, as a particularly sensitive group. The obtained result proved that the elderly feel higher temperature rates than younger people. In one of the simulations, new plantings were proposed to improve the local microclimate. The material temperatures of paved surfaces were also investigated. The article shows how the local microclimate and people’s desire to stay in a given space can be improved with new tree planting.

The direct release of energy from the groundwater under the building of the Sobieski Family Palace in Lublin, Poland, and the obtainment of heat and cooling energy for Heating, Ventilation, and Air Conditioning systems (HVAC) provide an opportunity to reduce electricity and heat consumption and to limit CO₂ emissions by 15–50%. The upgrade to the Sobieski Family Palace and the addition of new educational and administrative functions require state-of-the-art, energy-saving, and environmentally friendly solutions such as Fuel Cells and Hydrogen for Heating, Ventilation, and Air Conditioning (FCH HVAC) systems. As part of the program “Research for high-quality air in architecture and urban studies,” carried out since 2018 at the Institute of Architecture Planning, Department of Contemporary Architecture, Faculty of Civil Engineering and Architecture of the Lublin University of Technology, in 2021, further research was carried out in order to prepare for the potential implementation in 2022 of the project entitled “Development and Upgrade of the Former Sobieski Family Palace in Lublin. The main body of the building—educational and administrative function,” whose chief designer was Architect J. Wrana, Lublin University of Technology, 2021. The objective of this paper is to identify technologies and solutions specifically designed for HVAC systems in upgraded and renovated historic buildings. This paper is also a call for cooperation among institutions, scientists, higher education institutions, as well as an expression of appreciation for the immense energy stored in groundwater. This energy not only has the lowest carbon footprint but also is the only generally accessible large storage source from which we were unable to obtain ecologically pure energy before the introduction of FCH technology.

Urban structures of the cities are one of the most complicated structures inthe whole world. It depends on many factors, that continuously change and develop them.Among many research tools which can be helpful in understanding urban structure designing,there is a Space Syntax method. This method of analyzing grid structures provides a lot of information about connectivity and integration of urban space as a research area. This method was used to perform an analysis of the urban tissue of the city of Lublin. Conclusions resulting from those analysis help identify weaknesses and problematic areas on urbanlayout of Lublin, especially related to integration and connectivity of streets and may be used as a basis for further research.
