The article discusses the results of experimental studies of energy efficient ventilation system of sheepfold, using information-measuring system for remote registration of thermotechnical parameters of the ventilation systems.

They are given the results of testing of the experimental energy efficient ventilation system in the winter and summer periods.

This article presents methods and means of increasing an efficiency of heat pump system and hot water supply for residential houses on the base of using of the heat pumps «air-water», solar collector of energy and ground heat exchangers. The technological scheme of energy saving heat pump system of the rural house taking into account local climatic conditions is described. The study determines typical temperature parameters hybrid heat pump system’s elements at cold days in heating season. The expediency of use of solar energy and heat of ground for preliminary heating of the cold external air arriving to the thermal pump «air-water» is proved.
