摘要:The article considers problems and prospects of development of energy saving technologies in construction. The possible directions of improving the construction of residential facilities with the aim of increasing their efficiency are considered, taking into account different technologies. The main emphasis is on the use of solar panels as one of the most effective ways of saving resources. The maximum level of heliotropia for the Central black earth region is determined. To increase the efficiency of the solar battery it is proposed to develop a rotary device that allows you to change the angle of the battery in the vertical and horizontal planes. The dynamics of rotation in the horizontal plane should depend on the time of day, in the horizontal – season. The article presents the problem of determining the speed of rotation of the solar battery in the direction of the solar azimuth and relative to the horizon during the day, allowing you to use a slewing device with maximum efficiency. Increase efficiency when using the rotary mechanism will reduce the number of solar batteries with the same capacity of electricity consumption. Also the problem of determining the optimal number of solar panels.
