Solving problem of airflow in the open air space in double pitched roofs of passive objects with concrete cover
Authors: Plachy J , Šál J 
Published: November 2020

Abstract
The paper deals with air flow in open air gap in pitched roofs with folded roofing. The sloping roof is thermally insulated to the passive standard. Double-skinned roofs work with the drainage of moisture from the air gap based on the difference in water vapor pressure that is generated by the warming of the air gap. Moisture removal is suppressed due to the large thickness of the thermal insulation. The paper compares experimentally measured values with values obtained by calculation using the appropriate computer software. For experimental verification of the air flow, a model of the roof cladding was constructed, on which air flow in the air gap was verified. There was no air flow on the roof model. In the theoretical calculation the flow occurred.

Published: November 2020

Abstract
When making a prototype during design in industrial design, specialists use the data on the strength characteristics of filaments for extrusion provided by the manufacturer of equipment for FDM printing. It is likely that the strength characteristics of the product may deviate from the characteristics of the threads. The authors suggested that the samples of the cellular structure made on 3D printers from polylactide with an internal volume filling of 10% with the filament laying direction according to the standard settings of the equipment manufacturer during the experimental determination of strength characteristics will demonstrate values several times lower than the samples with filling the cell volume with polylactide by 100% and having in their geometry the same direction of laying the extrudable material. To confirm the hypothesis put forward by the authors, a study was carried out of the characteristics of products made of polylactide using the FDM printing method. A comparison is made of the relative change in some parameters of the samples (mass, elongation, and the force used to break the samples), the two devices for growing prototypes – 3D printers MakerBotReplicator 5 Gen and MakerBotReplicator Z18 in percentage terms. Recommendations are given on the optimal operation of equipment for 3D printing, depending on the goals set by the user. The results can be used to select equipment for printing and sample production technology, cell filling density and amount of material when creating a prototype using the additive method in industrial design.

Abstract
The technology of obtaining multicomponent high-quality concrete using limestone powders as fillers is considered. In order to select fillers for powder-activated concrete, a study was made of the water absorption of limestone gravel of various kinds. According to the water absorption index, eight categories of limestone species have been identified. It was revealed that organogenic limestone is one of the materials that is preferred as a filler for high-quality concrete. The experimental results were obtained and graphical dependences of changes in the tensile strength under bending and compression, the dynamic modulus of elasticity and water demand of organogenic cement composites filled with limestone from granulometric composition and filler content were constructed. It has been established that the best strength properties are manifested in materials with optimal indicators of the content and size of limestone and silica powder.

Published: November 2020

Abstract
Paper is devoted to the actual problem of managing resource flows of development projects as complex, unique, and open systems, across the different project lifecycle stages that differ in content and are distributed in space and time. The idea was to create a single throughout system for managing resource flow processes of the long-term projects. The research goal included development of theoretical and methodological approaches that can be used in order to manage the combination of development project resource flows using “order from chaos” paradigm. That includes by-stage organization of resource flow processes on of macro-, meso- and microscale, going from sources and sinks of the chaotic project environment resolve to ordered stages of project life cycles. It is proposed to implement resource flow management in form of the stage and resource-based “project-logistic” relay of a triune movement, ordering and transformation of the resource flow processes. This relay is created within a project-logistic field of project management that change by project phases. Synergetic effects of self-organization and self-control appear in the project logistic field due to horizontal interactions, sharing experience, competences, and values among the stakeholders in course of transforming entropic resource-flow processes into the negentropy processes related to project phase goals (attractors). Results can be used to forecast and develop multilevel resource-flow and process systems arranged by resource sources and sinks, and chaotically ordered for projects in different application areas. Further research perspectives include development of self-control and self-organization forms for development projects stakeholders that would comply with international best practices, and fit corresponding project stages.

Energy management strategy in the construction industry
Authors: Prokhorov S 
Published: November 2020

Abstract
Saving energy resources is the first priority of the world community. In modern society, construction industry has a huge impact on the economic, social and technological environment of human life. New architectural forms and concepts are emerging, building materials and technologies are improving, environmental friendliness and friendliness of buildings to the surrounding nature increases. Currently, issues related to improvement of the economy’s energy efficiency are attracting everyone’s attention. Projects of energy-saving and energy-active houses are becoming increasingly popular. Existing construction regulations originate in the 70-90s of the last century, and do not reflect modern reality. Another important aspect of the introduction of modern technology is the environmental pressure during construction and installation works. It raises a question about the need to develop economically and technically sound standards in the design and organization of construction, compliance with which would be monitored not only at the stage of project documentation, but also during the building process. The study addressed the issues of energy consumption reduction at the construction design and maintenance stages, during building and installation works, as well as in sanitary, technical and material support of construction production.

Abstract
The aim of the study is to identify ways to improve the efficiency, reliability of the dust collection process and improve the aerodynamic properties of cyclone apparatuses in the gas cleaning unit. The analysis of existing methods of cyclone filtration of fuel gases is carried out. Bench tests of a cyclone filter based on the serial cyclone CN-11-200 were made, and the aerodynamic characteristics of its operation were found. The efficiency of the use of multi-cyclone apparatus, the elements of which combine both stages of cleaning, are also analyzed. The problem of finding the optimal location in the apparatus of cyclone elements with semi-tangential inlet nozzles are solved. A numerical model of a multi-cyclone is created and several options for the arrangement of elements are considered. The most effective location is determined taking into account the overall hydraulic resistance of the device. The numerical model also made it possible to evaluate the influence of various factors on the dust sedimentation efficiency in the developed cleaning device.

Abstract
The calculation involved in the design of integrated heat-hydraulic air-conditioning system in which air is supplied through the raised floor was presented. Calculations were made using the premises of an office building in Yekaterinburg, Russia. Raised floor in the current study was presented in the form of a channel with a concrete wall on one side and chipboard -on the other. It has been successfully established that the loss of pressure during air movement in the raised floor space is minimal, this was suggested as a result of the possible uniformity in air supply to the air distributors. It was also demonstrated that due to transmission losses through the walls of the raised floor, the cooling capacity of the air conditioning system was significantly reduced (up to 15%). Following the results obtained, conclusions were drawn about the main features of such systems.
