Natatoriums - Indoor Swimming Pools

Condensation, mold and bacteria associated with excess condensation can be a serious concern in critical areas such as indoor swimming pools where mold and condensation are chronic problems.

Thermal comfort in indoor swimming pools is nearly impossible without using IQ Radiant Glass. Without IQ Radiant Glass, one has to compromise between maintaining the building, energy consumption and the comfort of the swimmer. IQ Radiant Glass allows for lower air temperatures, less energy consumption and TOTAL COMFORT for the user.

The ideal relative humidity in an indoor pool is about 70%. When relative humidity is low, it generates a sensation of cold, caused by the fast drying of the skin. When relative humidity is high, it causes an unpleasant suffocating sensation, due to too high temperature and humidity level. During the winter, the double glass panes, even with a room temperature of 82.4 °F (28 °C) in the swimming pool, irradiates an intense ‘cold glow’ that makes the swimmer shiver when she comes out of the water.

If the internal  relative humidity level is high, it generates a risk of surface condensation on cold walls and glass surfaces. This risk increases when thermal insulation is not good and outside air temperature drops.

 

Condensation on double pane glass is generated under the following conditions:

 

70 % RHL - outside air temperature 53.6 °F (12 °C)

60 % RHL - outside air temperature 42.8 °F (6 °C) 

50 % RHL - outside air temperature 32 °F (0 °C)

The three determining factors of condensation are:

 

  • Outside air temperature 

  • Relative humidity level 

  • U-value:

 -Single pane glass = 1.021 Btu/hr ft2 °F (5.8 Watt/m2K)

 -Double pane glass = 0.528 Btu/hr ft2 °F (3.0 Watt/m2K)

 -Triple pane glass (gas filled) = 0.317 Btu/hr ft2 °F (1.8 Watt/m2K)

 -Low-e glass = 0.229 Btu/hr ft2 °F (1.3 Watt/m2K)

 -IQG = 0.148 Btu/hr ft2 °F (0.84 Watt/m2K)

 

Condensation water can damage the windows, the floor, and even the double pane glass. When relative humidity level is 70 % and outside temperatures are extremely low, IQG is free of condensation.
