Abstract

This study presents the results of the analysis on the energy balance of a single-family residential home built in 1986. The authors assess the proposed construction improvements in terms of their ability to enhance the building's energy efficiency and comfort. The studies were carried out for the needs of the owners who saw the necessity of reducing the maintenance and heating costs of the house and of improving their living conditions. The on-site studies and analyses of the building concerning the calculations for the proposed variants of solutions have pointed to the necessity and relevance of a thermal modernization of the building. The analyses took into consideration the growing requirements of thermal insulation of walls, the EP factor and the growing use of energy from renewable sources. The proposed modernization steps and energy audit calculations helped to select the most efficient solution.
