NTRODUCTION
The construction industry has been developing in
the last ten years. Measures to improve heat
protection of buildings under construction in
countries around the world, energy crises in
recent years are driving their development. Since
the 1990s, in many foreign countries, the
standard size of external barrier structures
protecting against heat has increased several
times.
The requirements for heat protection materials
used today are constantly increasing, the
standards
of

accelerating for some construction structures, as
well as for all buildings and structures.
A comprehensive approach to energy saving is
necessary to reduce heat loss. The main purpose
of the compactness indicator is to serve as a
coefficient equal to the ratio of the external wall
surface to the internal volume of the wall.
Cylinder, hemispherical and other non-
traditional shapes can be used to decorate the
outer wall surface. In order to reduce energy
consumption, the standards for the design of
building envelope elements are being reviewed,
modern protective materials for their heat
protection properties, application of standards
and elimination of infiltration, ventilation
through windows and doors, etc. is being
implemented by applying; Also, it is possible to
increase the energy consumption of building
rooms by differentiating them according to the
order of use [1]. It is recommended to place low-
heated rooms (closets, warehouses, santuguns,
garages, etc.) as buffer elements transversely to
the north. It is very important to plan building
areas and their proper orientation. In order to
effectively use solar radiation, the southern wall
or roof of the residence should be exposed to
sunlight from 9:00 AM to 3:00 PM even when the
weather changes. It is necessary, and measures
should be taken against the southern part of the
facade of the building to remain in the shade.
Nowadays, helioarchitecture is developing
rapidly all over the world. It is known that a two-
story house in a sunny area can provide itself with
electricity, and can prepare a reserve for the
winter. For this, it is enough to equip the roof
surface with solar batteries.
Calculation of shading of panels is carried out
according to existing methods. Practical
recommendations for moving the panels away
from shading objects: in the southern regions -
2N; at 400 latitude - to 2.4N; At 450 latitude, it will
be equal to 3N. N is the height of the shading
object above the panel level.
Scientists are not satisfied with this approach.
They are creating third generation helium
receivers [2]. When the inventions of the first
generation began to be adopted only by the
southern population, the second generation - the
locator helium receivers - began to be used in
experimental trials.
Today, research and experimental testing of the
use of solar energy is carried out in two
directions:
1. Low-power (low-temperature) heating for
providing hot water, for heating civil and
agricultural buildings and structures;
2. Medium and high-power thermal technological
processes, obtaining various materials for
synthesis and melting;
The main reason preventing mass use of solar
devices is the height of its comparative price of
1500-3000 US dollars per m3/day, the payback
period is also long, in general, the payback of solar
devices can be determined according to the
following formula [3]: Today, research and

/(QCT),
Here Sc is the comparative price of the solar system, soum/m2
Q-the amount of annual heat released from the roof of the solar installation Gcal/m2;
CT - traditional energy source issíqlík price, sum/b cal.
The formula for determining the duration of energy compensation for the provision of hot water without
additional heating:

are the total sums of
energy capacity and weight of helium devices,
solar collectors and auxiliary construction
materials;
Qr is the amount of heat produced by the heating
plant in the middle of one year and the calculation
period of its use.
The coefficient of 1.2 takes into account the
energy consumption during the installation of the
solar system.
3 building energy payback periods, which are
distinguished by wall constructions, heat-
absorbing stone and heat protection:
- brass pipe heat-absorbing panel steel thermal
protection, energization and DVP beam structure
energy compensation period -1.04 years;
- the energy recovery period of the same
aluminum heat-absorbing ribs, steel sheet - 1.16
years;
It can be seen from the obtained data that the
energy recovery period of the first structure of

the collector is shorter than that of the second
structure, and this is due to the high energy
capacity of aluminum. The results of the
calculations also show that the comparison of the
price index only with the traditional sources of
the supply of helium devices with electricity is not
objective [4].
It has been fully proven that these devices are
ecologically clean and harmless in modern times.
The use of these environmentally friendly solar
batteries has developed well in our country, and
in the last year, all state institutions have been
equipped with these devices.
