This paper presents a method for economic calculation of the heating systems, relying on data from other systems that may influence the energy demand of the heating system. This method can be used, fully or partly, for the consider economic feasibility of energy saving options in buildings, compare different solutions of energy saving options in buildings (e.g. plant types, fuels), evaluate economic performance of an overall design of the building (e.g. trade-off between energy demand and energy efficiency of heating systems) and assess the effect of possible energy conservation measures on an existing heating system, by economic calculation of the cost of energy use with and without the energy conservation measure. The approach of the calculation method is according to a global point of view (overall costs). However, depending on the objectives of the investor, the calculation method may be applied considering only selected specific cost items. For example, calculations concerning alternative solutions for heating systems may be performed considering only costs for the domestic hot water system and the space heating system.
