AB - Buildings with indoor swimming pools have a large energy footprint. The  source of major energy loss is the swimming pool hall where air humidity is  increased by evaporation from the pool water surface. This increases energy  consumption for heating and ventilation of the pool hall, fresh water supply  loss and heat demand for pool water heating. In this paper, a mathematical  model of the swimming pool was made to assess energy demands of an indoor  swimming pool building. The mathematical model of the swimming pool is used  with the created multi-zone building model in TRNSYS software to determine  pool hall energy demand and pool losses. Energy loss for pool water and pool  hall heating and ventilation are analyzed for different target pool water and  air temperatures. The simulation showed that pool water heating accounts for  around 22%, whereas heating and ventilation of the pool hall for around 60%  of the total pool hall heat demand. With a change of preset controller air  and water temperatures in simulations, evaporation loss was in the range  46-54% of the total pool losses. A solar thermal sanitary hot water system  was modelled and simulated to analyze it's potential for energy savings of  the presented demand side model. The simulation showed that up to 87% of  water heating demands could be met by the solar thermal system, while  avoiding stagnation. [Projekat Ministarstva nauke Republike Srbije, br.
