An analysis made of an energy-efficient house, for which the energy requirements for heating shall not exceed 40 kWh/m2/a. The calculations used air collectors with an area of 60 m2 and performance efficiency of 70%, which are available commercially. In the analyzed building the solar heating system provides almost full coverage of energy needs throughout the year, with a small shortfall occurring in December and January. The above-mentioned deficits at the beginning and end of the year can be supplemented with other alternative energy sources.
