Using Temperature to Control Condensation in Cold Climates

Initially, water vapor diffusion was seen as the likely culprit for condensation problems; designers and consultants spent hours running and analyzing wall assemblies using the dewpoint method. With such analyses came the concept the wall system should be tuned for maximum condensation resistance by altering or selecting the appropriate permeability of the wall components. However, to create a truly robust wall system with the greatest condensation resistance and drying potential, designers need to look at altering the temperature profile of the wall assembly by moving insulation as far as possible to the exterior of the wall.

There are many issues to consider when designing a natatorium, including the choice of structural systems, building enclosure components, mechanical systems, and the operation of adjacent spaces in multi-use facilities. The intent of this article is to discuss the typical problems that the authors have investigated in over a dozen existing natatoriums and provide practical guidance for avoiding those problems through diligent and careful design and construction.
