Außenwandkonstruktionen für Schwimmhallen

External wall constructions for indoor swimming pools.

The continually increasing requirements for general comfort conditions combined with an ever growing demand for the widest range of wellness facilities result in numerous new-build and extension projects in the hotel and tourist trade as well as in private homes (example see fig. 1). With public swimming pools the focus of attention is on suitable measures to increase the energy efficiency of the relevant parts of buildings and to modernise and make them more attractive at the same time. With these buildings or parts of buildings we are dealing with buildings used as swimming pools, jacuzzis or saunas and much more exposed to the effects of moisture compared to the normal boundary conditions of recreational areas: Not only are the temperatures and humidity content much higher and therefore the partial pressures of the water vapour in the air indoors on a completely different scale, but they are generally open and used at different times. This means that the long-term operation of such a building free of damage and shortcomings requires a correspondingly suitable construction of the surrounding components and thus a special expert assessment of the building physics boundary conditions. Whereas the boundary conditions relating to the temperature and moisture in the building (and the corresponding methods) to be applied to residential or office buildings are regulated by standards and the effects on the corresponding construction of the building in practice are therefore more or less familiar, there is a general lack of this information for indoor areas with high humidity in general and swimming pools in particular.
