Abstract:
This paper attempts to give an overview of the positive effects when conventional fuel - light home heating oil or fuel oil is replace with fuel from renewable sources of energy - wood biomass as energy source for heating the premises of public objects. While it’s done consideration of the current situation in a several public buildings, a heat capacity is required in accordance with standard procedure for calculating, there are proposed solutions for the reconstruction and replacement of part of existing heating installation. The main emphasis is given to the analysis of the possibilities of replacing fuel oil with wood pellets and benefits of it. By analyzing of the current situation and the situation after reconstruction, an overview of the parameters of the economic justification for applying pellets in both cases is given. The suggested mathematical model gets parameters therefore indicators of justification of this activity. This is confirmed by the financial benefits, by which clearly outlines the justification for accession to this reconstruction, but emphasis is also given by non-financial and other benefits, such as environmental impacts on living and working environment.
