AB - Energy systems for consumers’ supply with sanitary hot water (SHW) can be  considered as a separate category of the system with many similar functions,  performances and integral elements. This similarity of energy systems for SHW  supply and the way in which they are used enable systemic planning, proposing  and undertaking measures for improvements and advancements. This is possible  not only by the reconstruction and modernization of existing technological  solutions but also by their replacement with new, modern and more efficient  solutions. The basic idea and the aim of this paper is the development of a  concept for integrated and upgraded system of SHW supply for different types  of buildings from residential to more complex buildings intended for  different purposes. The analysis is based on the application of a systemic  approach adapted to the conditions in urban communities and includes only  modern but commercial technologies. This paper presents the results of a net  energy analysis of integrated central and solar hot water supply system and  compares it with the conventional sanitary hot water system in the City of  Novi Sad, Serbia. The proposed methodology is demonstrated through a  simulation example. It is shown that 23% reduction in the total system’s  costs can be achieved as compared to the existing solution. Also, the  methodology is applied to a residential block as a unit and obtained results  indicate that investments in the development and construction of integrated  systems are justified.
