ABSTRACT
ABSTRACT: In the article the problem of equipping low-energy buildings with highly efficient and low emissive heating installations with the aim of minimizing heating costs is discussed. The subject of the study was a single-family house with defined construction for which the annual primary power demand, the annual final power demand and the heat demand for heating purpose, were determined. The heated floor area of this building is about 198.1 m2. A special computer program packet dedicated to passive building design (PHPP) was used for computational analysis.
Keywords: low-energy building, energy sources, energy consumption, energy costs
