Research consisting in the analysis, definition of parameters of a high degree of energy efficiency with a guaranteed share of renewable energy is of particular importance in the implementation of the concept of sustainable development. In Vienna, there have been built buildings whose construction and operation inscribe into an extensive research programme that includes an energy management strategy according to the latest standards developed for energy-efficient construction. These buildings, which are represented by research and educational institutions, are a kind of research field for new technologies and solutions to optimise energy consumption. In architectural terms, the implementation of photovoltaic façades signals the high technological level of prototype solutions. The Author’s research methodology was based on the analysis of data characterizing new and modernized buildings, carried out on the basis of current internet sources, literature data and local visions during her study trip to Vienna. The aim of the paper is to present the energy concept of buildings, used to optimize energy acquisition and consumption, as a signpost for the application of guidelines and standards in possible Polish solutions.

Museums have become cultured places to exhibit art and to survive that context or social milestone within society. On numerous occasions, the great museums have been commissioned to collect architecture by plundering the original sites and taking away part of their soul, and in many cases, the originality of the work loses its meaning without its original location and vice versa. In the field of restoration, different are the theories and concepts that should be taken into account for optimal interpretation, always depending on the criteria and sensitivity of each author. For that same reason, the discussion between the suitability of the reconstructions or their interpretation is obligatory, using a wide terminology to describe each of the processes.

This paper explores whether the historical heritage of a city with cement roots can be based on intelligent tools and applications introduced by the city. Smart cities are introducing a conceptual development model based on innovation and modern technology. The aim of the study is to presentation the current layout of the spatial structure of cement plants built since the beginning of the 19th century and the critical transformations that are taking place in the analyzed areas. Moreover the paper checks the transformation of degraded areas of former cement plants and whether the aspect of the city's historical heritage can be included in the strategic areas of a smart city.

The paper presents the results of tests on single shear bolted connections of cold-formed steel sections with a wall thickness of 4 mm made with standard fully threaded M16 grade 8.8 bolts. The tests were performed for connections with washers and without washers. The obtained results were referred to earlier studies of analogous connections using blind fasteners Huck BOM R16. The failure mode was identified, the load capacity and stiffness were compared, and a method to determine the non-linear load-displacement characteristics of such connections was proposed. The effect of stiffness of joints on structural response of exemplary cold-formed steel frame was shown.

The aim of the paper was a comparative analysis of energy demand for heating and human thermal comfort of a model single-family house with natural ventilation in various construction technologies (wood and brick), located in the Polish temperate climate. The frequency, as well as, the window opening area in the building have been optimized taking into account two objective functions: heating demand and number of thermal discomfort hours. The analyses were based on thermal simulations using the EnergyPlus program on the nine-zone model of the selected house. Each building construction case was calculated for two variants of external partitions insulation. The thermal model, separately for each zone, contained hourly internal heat gain schedules. All simulations were carried out with a 15-minute step for the full calendar year. Analyzes have shown that the heating demand for a building made in wooden technology is higher than a building in brick technology. The wooden building has a greater number of thermal discomfort hours. Increasing the insulation properties of the house increases the number of hours of discomfort.

The gas produced from the deposit usually contains various types of pollution. They are the reason for limiting its use, often making its use impossible. Therefore, it requires appropriate treatment. One of the main pollutants in gas is water. Its occurrence causes a lot of problems, especially at the stage of gas transport, such as the formation of hydrates blocking pipelines and apparatus, causes the phenomenon of condensation and corrosion of pipelines, especially if there is carbon dioxide or hydrogen sulphide in the gas. The paper presents a number of methods that enable drying of gas after extraction. Each of them has different parameters that will be achieved for the gas after it is dried. Depending on the required degree of drying, the economics of the process and compatibility with other dependent processes, the individual methods are more or less used in gas engineering. The paper discusses methods of absorption in ethylene glycol solutions, adsorption methods using silica gel, molecular sieves or calcium chloride and low-temperature processes such as Twister® supersonic separator, IFPEX-1® process and DexProTM process.
