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
is inadmissible in Russian climate conditions. Selection of structure
bitumen-rubber mixture and regularity establishment of its properties
allow receiving a material with a wide temperature range of application.

The foreign experience in using the hollow
stones was considered, relevant strength and thermal engineering
were made. The conclusions on the renunciation of widespread
stones of high voidage for lining multilayer walls and the possibility
stones with not more than 15% range of hollowness were made.

The article presents the results of a field experiment, which object
to estimate the efficiency of the use of lightweight steel frame
the course of the research there were determined the heat flow through
frame structure, the impact of thermoprofiles on temperature conditions
room, the level of thermal protection.
The aim of this work was
to develop a methodology for calculating the parameters of the
of air in the ventilated gap, which allows determining the optimal
dimensions of hydraulically mounted air gap in the facades of buildings
structures. As a result, it was found
that, in terms of minimizing the loss there must be designed a
curtain facade with ventilated air gap, expanding upwards.

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

The aim of this study was to develop evaluation
criteria for the various options of the project on the basis of
the initial design phase. Objective of the study was to develop a
for assessing the architectural decisions on the basis of the building
information model (BIM), formed by the program Autodesk Revit
