Assessment of the Energy Characteristic of the Terrace House

In the article, the energy characteristics of a terraced house located in Kielce were assessed. The analyzed house was put into use in 1982. Due to the old manufacturing technology, mainly in the area of the materials used, to limit significant heat losses, it has been thermally renewed many times. The aim of the calculations was to indicate the financial benefits, in example to reduce the costs of maintaining the house and to provide its residents with the proper comfort of use of the building, also taking into account the health aspects. The analysis of the object was made in several stages. Proposed are changes reducing the demand for non-renewable primary energy Ep, using modern thermal insulation materials, joinery with low heat transfer coefficient and renewable energy sources. As a result, an energy-efficient building that meets WT 2017 was obtained. The annual demand for non-renewable primary energy EP was determined using the Certo 2015 program in educational version 1.3.3.0. (paper)
