This study presents an evaluation of the application of thermal insulation, solar panels, and an efficient boiler in a kinder garden to improve energy efficiency. The main objective of this study is to identify and analyze the benefits of using these technologies in reducing energy losses, increasing clean energy production, and achieving economic benefits. Thermal insulation is used to limit the transfer of heat between the building and the external environment, reducing energy losses for heating and cooling. In our case we have a saving of 7148 kWhr/year. The installation of the solar panel plant for heating sanitary water has brought an annual economic benefit of 102,583 ALL per year, meanwhile the choice of a gas boiler for heating the premises has been more cost effective compared to the use of oil.

There are viewed the following types of asymmetry: mass, linear and asymmetry of fixing points of big elastic elements to the spacecraft’ body. There is shown increase of the microacceleration module while asymmetry of the mentioned types appears. The conclusions about importance of geometrical symmetry of space laboratory for successful realization of gravity-sensitive technological processes on its board were made.
