This paper presents a comparative analysis of the carbon footprint, energy demand and life cycle costs of a model of a building located in the Central Europe climate zone. One specific example—the quantitative differences in global warming potential, life cycle costs and thermal comfort—has been shown, depending on the different construction (wood, brick) and heat sources used; traditional and energy-saving solutions have been considered. The research was carried out using the EnergyPlus simulation program for a multi-zone model of a naturally ventilated single-family house. Calculations were made for a 25-year life cycle using the standard climate data for Warsaw (Poland). The real occupancy schedule of the individual rooms was adopted and the instantaneous ventilation airflow was modeled, and its intensification due to the additional opening of windows was optimized. An estimated budget of the entire structure of the building and the heat sources was used for the cost analysis. The research has succeeded in developing some general conclusions and guidelines and recommendations for both the investors and designers of energy-saving and environmentally friendly houses. Considering the most economical an ecological solution, wooden houses are better than brick houses. In the wooden building, however, there are a larger number of thermal discomfort hours.
The household sector in Poland consumes more than 25% of final energy. At the same time, residents reported dissatisfaction with the thermal conditions during the summer months. This paper details the search for passive and energy-efficient solutions to improve thermal comfort in Polish dwellings. A five-story, multi-family building was selected for this research. Analyses were conducted in apartments located on the top two floors using EnergyPlus (for thermal calculations) and CONTAM (for air exchange calculations) simulation programs for current and future climatic conditions. The stochastic behavior of people when opening windows and automatically controlled systems supplying external air to the building was considered. Airing the apartments by opening windows increased the heating demand but reduced the number of thermal discomfort hours by over 90%. The degree of airing by opening windows depends on residents opening their windows; therefore, a mechanical supply of external air controlled by both internal and external temperatures was proposed and tested.
The aim of the research presented in the publication is a qualitative analysis of elements of small architecture on the campus of a research university of the Silesian University of Technology. The research was carried out during the implementation of the research project entitled: “Art. and Design in Public Space.” As part of the project, further objects are created in the field of education, art and design. Made: 3 Red Cubes - Sight - Influence of geometric solids on the perception of the surrounding space, 4 numbered BenchMan benches, Le Corbusier’s Modulor with graphic information, Kinetic Sculpture. All spatial elements are to draw attention, provoke reflection, present the work of students and employees, and above all, inspire and encourage the use of the design in small architecture. Selected elements are modifiable, portable and can be further created, and the process of creative activities is open and possible to continue. The project is open and has a developmental character. Further spatial elements will be added. The main slogan of the project is: “Change the environment and inspire others.” The main goal of the project is to give “Life in Space”. During use, research is being conducted, including observation of user behavior, the impact of given objects on their users. The main research results are the effects of qualitative research on the changed space. They showed that all the presented spatial elements change the existing space, make them think, inspire, introduce a factor of interest in this space, convey information about space. The creative process in this project is an open activity and enables further transformation and modification of this space. It is also a factor that introduces an element of creativity and attractiveness of space through constant changes and other aesthetic and functional possibilities of space. The most important conclusions include the fact that introducing minor changes to small architecture in public space using art and design gives great results in the form of activating public space, improving aesthetics and functionality.
