Application of vibration damping sheet in thin-walled construction designs allows reducing negative vibrations considerably. Existent bituminous and bituminous-rubber materials have insufficient vibration damping in the range of negative temperatures that is inadmissible in Russian climate conditions. Selection of structure bitumen-rubber mixture and regularity establishment of its properties will allow receiving a material with a wide temperature range of application. As an object of research there was chosen the polymeric matrix representing a mix of two materials – butyl rubber and bitumen, plasticized by industrial oil I-20A; the filler – swept of MTD-2 brands. The dependence of physical and mechanical properties of a material on the contents of bitumenbutyl rubber in a mix was established. The material based on the received mixture has effective vibration damping in the range of temperatures from -40 to +40 °C. 10.5862/MCE.43.2 damping sheet bitumen rubber physical and mechanical properties,; temperature https://engstroy.spbstu.ru/article/2013.43.2/ 02.pdf

 Application of stones of high voidage in the facing layer of the multilayer walls Because of the increasing regulatory requirements for heat-shielding properties of the exterior walls multi-layer building envelope became widespread. National practice of operation of multilayer outside walls revealed their increased defects, and first of all, this refers to the facing layer, usually performed with the stones with high voidage. Facing layer besides its aesthetic properties should reliably protect the internal structures from the negative environmental impact in the course of the operation period of a building. This can only be achieved through an analysis of its work (both the strength and heat engineering), which was often out of sight. The purpose of the study was to assess the possibility of further widespread use of stone masonry with a high voidage as the facing outer layer in Russia, and to identify the most efficient way to analyze the stress-strain state of the top layer. The foreign experience in using the hollow stones was considered, relevant strength and thermal engineering calculations were made. The conclusions on the renunciation of widespread application of stones of high voidage for lining multilayer walls and the possibility of using stones with not more than 15% range of hollowness were made. It was also concluded that the most reliable mode of deformation of the facing layer can be obtained from the joint strength and thermal calculations based on the results of monitoring of existing buildings, as well as field and laboratory tests. 10.5862/MCE.43.3 monolithic buildings face brick layer multilayer walls thermal engineering of outside walls https://engstroy.spbstu.ru/article/2013.43.3/ 03.pdf

 Settlement and experimental control of energy saving for buildings This paper is devoted to the solution of an actual problem — energy saving and increase of energy efficiency of buildings. The express method of settlement and experimental control of energy saving on the basis of the specific characteristic of thermal energy consumption for heating and ventilation was developed. Advantage of the method is that it allows assessing the efficiency of a complex of energy saving actions without measurements of summary solar radiation under the valid conditions of overcast and domestic thermal emissions at comparable to GOST 31168 accuracy of results. On the basis of the developed method assessment of efficiency of a complex of the energy saving actions realized in an operated multicompartment residential building was made. Based on the results of the conducted pilot researches it was established that the specified building met the requirements for energy saving according to the SNIP 23-02, a class of energy saving for the building was C (normal). Method was tested on the results of the pilot studies executed for the same building in accordance with GOST 31168. Approbation confirmed the reliability of the results received by an offered method. The method can be used during the monitoring of energy consumption and the energy audit of buildings. 10.5862/MCE.43.4 energy efficiency classes energy saving settlement and experimental control energy audit express method https://engstroy.spbstu.ru/article/2013.43.4/ 04.pdf

 A field experimental investigation of the thermal regime of lightweight building envelope construction The efficiency of heat consumption of buildings depends on many factors. Primarily they are space-planning and construction decisions, that is the level of thermal protection of certain claddings and buildings on the whole. In order to improve the thermal protection of buildings currently the multilayer building envelope is used in construction. In this connection, the issue of determining the thermophysical properties, in particular, reduced resistance to heat transfer is relevant. The article presents the results of a field experiment, which object was to estimate the efficiency of the use of lightweight steel frame structure. In the course of the research there were determined the heat flow through the frame structure, the impact of thermoprofiles on temperature conditions in the room, the level of thermal protection. The object of the field observation was one-family dwelling in the Leningrad Region. As a result of researches the reduced resistance to heat transfer and the thermal homogeneity value of lightweight building envelope construction were received. 10.5862/MCE.43.5 building envelope heat flow reduced resistance to heat transfer https://engstroy.spbstu.ru/article/2013.43.5/ 05.pdf

 The diffuser design of ventilated facades The main problem in the design of front systems is an empirical choice of parameters and the air gap between the cladding panels, causing appear of unventilated layer. Inadequate ventilation leads to icing of substructure elements that go into the air ventilated gap, and the top layer in winter, reduction of heat-protective properties as a whole. The aim of this work was to develop a methodology for calculating the parameters of the hydraulic flow of air in the ventilated gap, which allows determining the optimal rational dimensions of hydraulically mounted air gap in the facades of buildings and structures. As a result, it was found that, in terms of minimizing the loss there must be designed a ventilated curtain facade with ventilated air gap, expanding upwards. 10.5862/MCE.43.6 ventilated facades free convective flow air gap cone profile in hinged facade optimum width of the air gap polytropic index heat flux energy efficiency exterior building envelope https://engstroy.spbstu.ru/article/2013.43.6/ 06.pdf

 Miftakhova Dinara Extremal calculation problems of free convective movements in ventilated facades Systems of ventilated facades recently gain the increasing popularity. First of all it is explained by multifunctionality of these systems. Ventilated facades not only give the buildings expressive architectural shape, but also provide protection of the building against external influences and effectively cope with thermal protection. The main existing techniques for calculation of these critical structures are based on normative requirements. The hydraulic method of calculation of ventilated façade systems with the help of extremal problems is presented. Extreme conditions divide the actual and virtual movements of viscous air in vertical ventilation gaps. Their application leads to the weak formulations of limit problems convenient for an assessment of hydraulic elements of motion. The method was based on an extremal problem of Cross, the decision was provided by means of Krokko's equations. 10.5862/MCE.43.7 free convective movement barotropy pressure losses limit problem topology https://engstroy.spbstu.ru/article/2013.43.7/ 07.pdf

Objective of the study was to develop a methodology for assessing the architectural decisions on the basis of the building information model (BIM), formed by the program Autodesk Revit Architecture. The study suggested new compact solutions for evaluating insolation on vertical and horizontal surfaces and simplified algorithm for calculating the heat loss of the building, allowing the introduction of the relevant information in a program like Revit Architecture to simulate virtual water and energy balance at the early stages of design. Applying the final value tariffs for water and electricity supply of the area, you can get a virtual operating cash flow. For correct economic comparison of conceptual design options you should take into account time differences in costs and revenues by discounting. For rapid assessment of design solutions a model that allows you to simulate the scheduling of the facility necessary for the formation of the investment cash flow was developed. The proposed method can significantly improve the ability of the variant design incorporated into the program such as Revit Architecture. 10.5862/MCE.43.9 energy efficiency resource saving architectural and structural design Building Information Model project evaluation https://engstroy.spbstu.ru/article/2013.43.9/ 09.pdf
