Background EU has set high binding goals for the use of renewable energy. Looking at the last years' development it seems that renewable heating does not follow the dynamics of the so-called green electricity production. Tariffs or bonus model, deriving from so far the most successful model of the feed-in tariffs applied in renewable electricity sector, could improve the situation. The first such scheme was introduced in the UK, coming into force in June 2011. I wanted to check if this could be the right way to enhance the renewable heating in public buildings in Slovenia. Results For this purpose an overview of the current renewable heat supporting mechanisms and experienced gathered so far is made and comparison of the bonus with other models is shown. To check the idea in practice a simulation is made using the real case examples of two public buildings in Slovenia. Results from the literature and case studies were mainly positive and confirmed the initial idea. Hence a basic design of the scheme was made and further development proposed. Furthermore, estimation on the needed funds for a ten years renewable heating retrofitting programme for public buildings was derived and compared with the actual subsidy spending and the costs planned according to the national REAP. Conclusions The results showed good perspectives for the proposed model. However, further options like different scale (households, district heating) and technologies (solar and geothermal, heat pumps) options should be analysed. A much more comprehensive analysis of the suitable height of the tariffs is needed for well designed scheme.
