This paper analyses energy efficiency of thermomodernization project on the example of three forest lodges located in the Świętokrzyski National Park. Currently, one of the basic requirements posed for the buildings subjected to modernization is to reduce carbon dioxide emissions even above 80% in comparison with the original values. In order to fulfil such criteria, it is necessary to apply alternative solutions based on renewable energy sources. Due to limited budget, low cubic capacity and location of the buildings, solar collectors with storage tanks and biomass boilers provide a rational option. For such a case, the emissions of basic pollutants such as CO2, SOx, NOx or particulates is obtained. The study also gives the results of calculations of payback time (SPBT) for the investment for exemplary forest lodge.
