When conducting quality control, it is necessary to consider the quality of both each individual element of the facade and the quality of the hinged facade as a system. When structuring the review of tools for instrumental quality control of curtain facade systems, their application should be considered according to controlled parameters, which can be divided into two groups. The quality control group of facade system elements combines methods and tools used in quality control of building materials and does not require the contractor to know about the principles of the hinged facade system. The quality control group of the device (assembly) of the hinged facade consists of operations to determine the quality of the operability of the hinged facade system. This group is entirely based on the idea of the work of the hinged facade as a single system. Based on the results of systematization and generalization of data, it was concluded that the current regulatory documentation regulates the use of instrumental control tools, leaving aside the issues of organization that come to the fore when quality control of the hinged facade of a construction object as a whole, when there is a task of choosing and using several tools of instrumental control at the same time. It is these questions that should be the subject of further research.

This article presents experimental data on the effect of inter-window heating of the air gap on the heat-shielding properties of a wooden window. In recent years, Russia has significantly tightened the requirements for the heat-shielding qualities of translucent structures of buildings and structures. However, heat losses through the windows continue to account for a significant portion of the total heat losses through the window structures of buildings. Therefore, in order to reduce heat loss through translucent structures and solutions to the problem of energy saving in buildings, it is necessary to look for ways to increase the resistance to heat transfer of windows. One of the solutions for improving the thermal insulation of window structures and increasing comfort in the premises of residential and public buildings in the winter period is the use of inter-glazing space heating.

In this work new circuit solutions of R-S-latch and D-trigger having nonvolatile electrically programmable memory and nonvolatile shift register are presented. It shows that nonvolatile R-S-latch can be effectively used as a memory cell and simultaneously as write and read circuits for it, thus it makes possible to increase reliability of read operation from EEPROM at the expense of differential read for every bit.
