Abstract
Design solutions resulting from long-term research on swimming pool halls are presented. Double-sheath outer wall structures are successful in long-term service where water vapour permeation is prevented close to the inner surface, and there is a ventilated air gap under the outer layer. Optimum structural designs for outer opaque walls and roofs are given, and an optimum glazed wall solution is proposed with a thermal and air curtain between the glass layers, which minimises structural damage by surface condensation. The stringent energy requirements for high-quality design of swimming pool sheathing are formulated, taking into account possible serious damage by surface condensation to peripheral structures and sheaths during operational breaks in heating and ventilation. Design parameters for the indoor environment are chosen so that the peripheral sheath can resist this fall-out loss.
