Designing, constructing and using of buildings with low energy consumption are a complex process requiring knowledge of architectural design, construction physics and building systems with the use of renewable energy sources (RES). The article presents the legal bases and characteristics of low-energy buildings. Implementation of the binding technical requirements in the field of hygrothermal characteristics consists of monitoring numerous parameters of an entire building, and in particular of its partitions and their joints and building systems. Therefore, the paper presents calculations regarding determining the material systems of building partitions and building joints with the use of professional software. The main part of the article is to establish the impact of energy-saving technologies on the energy consumption of the newly designed buildings, but also of the buildings that are undergoing modernisation processes.

As an element of structural and material solutions, aluminium and glass façades are the mainstay of urban architecture; they are especially used in public utility buildings. The article provides a review of architectural styles and trends of the 20th century, when exterior elevations began to take the form of aluminium and glass façades. It illustrates the main architectural trends of urban architecture in the 20th century and their evolution throughout the years. Furthermore, it specifies and refers to the architecture of the 20th and 21st centuries in Kraków and presents selected public utility buildings which have become an integral part of architecture in this city.

The current work presents the issue of determining the position of the observer using measurements registered with GNSS (Global Navigation Satellite System) receivers that Android mobile devices are equipped with. The discussed questions concern using GNSS measurement data, which have been made available in the Android system since version 7.0. The present paper has the character of a review. It demonstrates how measurement data can be obtained via Application Programming Interface. Moreover, it discusses the available software that can be for registering measurements and their initial analysis. Subsequently, it reviews scientific works concerning the problem of positioning with the use of smartphones. Special emphasis was placed on tests consisting in an analysis of phase observations registered using dual-frequency receivers. The summary of the article presents the prospects for using mobile devices in precise point positioning. It also points out the limitations to achieving high accuracy and reliability of such measurements.

The research issues discussed concern the impact of the environmental factor on the level of real estate transaction prices. In the face of the dynamically developing road infrastructure but also the increase in the volume of car traffic, it is necessary to take into account the effects of these changes in the area of property appraisal. In the group of price-generating attributes should be taken into account the noise level, because in many cases it may prove to be the most important factor from the perspective of real estate buyers. The research was carried out on the example of housing properties located at the main communication artery of Krakow.
