It is increasingly common in the architecture/building industry that glass is placed in the front of the proper façade and serves as a protective layer for the wall behind. This type of external glazing is also used as an envelope for timber façades. External protection by glass slows down timber decomposition and weathering as it screens out potentially dangerous climatic factors like rain, moisture, and frost. Timber-behind-glass is becoming one of the most promising typologies in façade design from a sustainability perspective. The presented paper discusses this new emerging architectural trend. The combination of timber and glass is expected to produce both very durable (long service-life) and simultaneously environmentally friendly façade as timber locks CO₂ into its substance.

In the study of historical architecture, especially the one that was transformed or ruined, of key importance is iconography, i.e. views of and panoramas of cities or their parts or individual objects.

The article is focused on identifying the role of the Department of Architecture Fundamentals and Architectural Design in shaping the architectural school of Kyiv National University of Construction and Architecture (KNUCA) as part of the Kyiv architectural school. It is performed by applying the deductive method, i.e. consistent analysis and study ranging from Kyiv architectural school elements. The article provides analysis of the key historic landmarks of its development, its fundamental principles, determined for the first time, methodological approaches, and prospects of development. Having undertaken the analysis, KNUCA was found to be playing a prominent role as a leader in methodology of training architects.

Vivid colours in external views of the latest works of architecture are not commonplace. Le Corbusier introduced basic colours delicately, on small fragments. Architects inspired by his work most often select rather small fragments, marking with only a single colour that is clearly contrasted with the entire composition. The construction of massings with vivid colours is the domain of either young and bold or experienced architects who can convince decision-makers about their proposals and rationale. The author presents structures with elements of various colours, as well as single-colour structures that feature surprisingly striking colours, completed by outstanding contemporary architects.

This article presents results concerning the hydrodynamics of a reactor with a porous fluidised bed (group D according to Geldart). Pressure drops were experimentally determined by gas flow through the bed and empty column. Using equations from literature flow resistance on the bed and gas distributor, critical velocity and terminal velocity were calculated and the obtained results were compared with experimental data. The equation which best described the work of the tested fluidised bed was identified through a process of trial and error. The influence of sieve being operated on pressure drops occurring during the process was determined and its applicability in the other conditions was verified.

The purpose of the article is to determine the effect of the addition of polypropylene fibres on the properties of concrete mixtures and hardened concrete. To this end, both destructive and non-destructive tests were conducted. The concrete mixture tests included the testing of the consistency, air content and bulk density of the concrete mixture. Investigations of hardened concrete were based on the determination of compressive strength by destructive tests, sclerometer and ultrasonic methods and tensile strength in bending tests. All tests were performed for seven series of concrete mixtures, differing in their fibre content. The results showed that the addition of polypropylene fibres to the concrete mixture causes changes in consistency, increases air content, and does not increase the compressive and tensile strength of concrete. It was also observed that the addition of polypropylene fibres does not cause significant changes in the bulk density of the concrete mix.

In this paper, a method for the automatic creation of bidirectional paths for AGVs in the Delmia QUEST software application is presented. The layout of transportation subsystem can be prepared in a spreadsheet. Based on it the file with input data is generated. Using programming languages included in QUEST, procedures were created and based on these procedures, a macro was built. This macro allows reading input data from the file and creates the transportation paths automatically. This enables the simulation model building to be less time consuming.
