ABSTRACT 
It is known that coal, natural gas and oil products, which are natural sources of energy, will be 
depleted in the coming years. More than 50% of them are spent on heating and hot water supply and 
household services. Much work is being done and research is being done to prevent this. This study 
draws conclusions on the efficient use of renewable energy. 
 
Keywords: Solar energy, construction of buildings, water circulation system, water supply, 
SEC (solar energy collector), energy source. 
 
Introduction. Energy efficiency of previously designed buildings was ignored. It has become 
the norm since Uzbekistan gained independence adopted normative documents. Including according 
to QMQ 2.01.04-97 * resistance to heat transfer of barrier structures used at the present time in 
accordance with the level of thermal protection 3-4 times greater than the heat transfer resistance of 
incoming buildings This is a non-conventional energy in the construction of buildings requires the 
use of resources. UN General Assembly №33 / 148 unconventional and newly generated energy 
according to the resolution The basis of the sources is the sun. In our country 300 there are more 
sunny days than days. The sun never sets on the whole world is a source of energy. Solar energy use 
2020 10% or more in most countries over the years, the EU for countries, this figure can reach 20-25%. 
That's why it stands spent on heating the premises and meeting domestic needs conventional fuel 
energy sources can be saved by 35-55% Insulation passive heating systems, including "Thrombus 
wall" to improve and use the solar system of the solar type The scientific and practical significance of the 
recommendation is great. The scientific content of the dissertation -of practical importance are these.
