plied by the ventilation system. An increase in humidity within the swimming area, taking into account the low-humidity limit and the building’s physical component properties, was also considered. In order to improve the sustainability of the still necessary ventilation system, it is equipped with heat recovery. Filter systems and pumps require a lot of energy. The energy required by the pumps is reduced by their position. Their location in the basement, below the pool level, allows the use of geostatic height. For ecological sb 5/2019
reasons, disinfection is made possible by electrolysis with reuse of hazardous substances. The water is extracted by an ultrafiltration system to recover the heat and the water itself. To coordinate and optimise these partially collaborative functions, there is a digital energy control system combined with the control system, electronic sales system and operation. An energy monitoring control regulates energy consumption. In this object, therefore, the practised principles of passive house construction are applied. 77
