Medium term development prospects of cogeneration district heating systems in transition country – Croatian case

摘要: A dominant share of Croatian cogeneration capacity and future potential belongs to district heating systems currently operating in almost all bigger mainland coastal towns. Since public plants cover only 10% requirements households services sectors it is reasonable assume that energy supply could take a relative absolute even conditions reduced heat demand imposed by implementation Energy Performance Buildings Directive.

In this paper comparison various concepts individual buildings has been performed with respect efficiency environmental indicators. Taking midsize town as an example profitability operation both biomass natural gas fired have analysed.
