Potential and scenarios of variants of thermo-modernization of single-family houses: An example of the lubuskie voivodeship

Abstract

The excessive air pollution in the Lubuskie Voivodeship and throughout Poland is a very serious problem. One of the main causes of poor air quality is low emission, which arises at a short distance from the ground (up to 40 m). The real reduction of low emission requires a series of measures. The most important of them, include replacement of non-ecological boilers heating single-family buildings, improvement of thermal insulation of outer building walls, development of public transport, limiting the movement of old, non-ecological cars, conducting extensive educational activities, economic support for the poorest families in pro-ecological activities, and development of district heating in urban areas. The issue of thermal modernization is also important from the point of view of ensuring an appropriate level of energy security in the social dimension. The article presents a scenario analysis of activities aimed at reducing low emission through economic support for thermal modernization of single-family houses in the Lubuskie Voivodeship in Poland. The results of the conducted research prove that it is possible to carry out thermal modernization of over 12% of all single-family buildings in the Lubuskie voivodeship, assuming that the co-financing would amount to 60% of the costs of such an investment. The analyses carried out in the article are closely related to low carbon development, and a significant part of emission of harmful substances into the air comes from heating single-family buildings in urban and rural areas.
