Design scenarios for renovation of sports complex: a case study

Abstract

This paper elaborates design scenarios for a sports complex in Croatia from a technical and economic aspect. Different energy options are analysed and two are additionally addressed and discussed as the most viable ones. The possibilities of sports complex renovation are shown by properly choosing the appropriate energy concept and thus reducing the overall cost for produced thermal energy by around 33% and reducing the carbon dioxide emission by a factor of 1.8 in comparison with its present state. Finally, this study presents an example of good practice, where renewable energy solutions can be proposed and where it is possible to cover around 70–80% of overall yearly costs from achieved energy savings for the novel plant that is assumed to be financed through a bank loan.
