Конгресс «Энергоэффективность. XXI век»: за рациональное энергопотребление

“Energy efficiency. XXI century” congress: for rational use of energy

On November, 20–20th, the Saint-Petersburg session of V International Congress “Energy efficiency. XXI century. Engineering methods for reducing energy consumption in buildings” took place. According to A.M. Grimitlin, senior secretary of the congress and president of “AVOK Severo-Zapad”, the main role of this event is educational. Nowadays everybody supports state initiatives in energy saving, but few of them know the ways of its realization.

Bitumen-rubber mixture for effective vibration damping sheet

The results of researches of a bitumen-rubber mixture design for the damping sheet are presented. 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.

Application of stones of high voidage in the facing layer of the multilayer walls

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.

Расчетно-экспериментальный контроль энергосбережения зданий

S.V. Korniyenko
Settlement and experimental control of energy saving for 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. 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.

Экспериментальное исследование теплового режима легкой ограждающей конструкции в натурных условиях

D.V. Petrosova, N.M. Kuzmenko, D.V. Petrosov
A field experimental investigation of the thermal regime of lightweight building envelope construction

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 diffuser design of ventilated facades

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.

Extremal calculation problems of free convective movements in ventilated facades

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.

 ANALYSIS
Теплотехнические свойства различных конструктивных систем навесных вентилируемых фасадов

O.A. Tusnina, A.A. Emelianov, V.M. Tusnina
Thermal insulation properties of various ventilated facade systems

Two constructive systems were considered – traditional widespread in practice and new system developed by authors. In the new system vertical profiles are replaced by perforated tapes made of anti-corrosion steel and granite tiles are fastened to the supporting structure in the nodal points. Numerical thermal analysis of two described systems was carried out using software TEPL. Solution of three-dimensional steady-state conductivity was obtained in the program.

Оценка энергоэффективности архитектурно-строительных решений начального этапа проектирования в программе Revit Architecture

S.A. Bolotin, A.I. Gurinov, A.Kh. Dadar, Z.H. Oolakay
An energy efficiency evaluation of architectural and construction solutions of an initial design stage in Autodesk REVIT Architecture

The aim of this study was to develop evaluation criteria for the various options of the project on the basis of information of the initial design phase. 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.
