INDOOR SWIMMING POOL DESIGN

An indoor swimming pool requires a complex, integrated design to control humidity, manage air quality, and ensure structural integrity. The best practices cover several key areas, including environmental control, structural considerations, safety, and energy efficiency. ​ Environmental control Proper management of air and water conditions is critical for the longevity of the pool area and the health of its users. ​

 

We design the heating and ventilation to keep the air temperature approximately 1°C warmer than the water temperature to minimize evaporation. An integrated HVAC system should handle heating, ventilation, and dehumidification do for dehumidification we usually specify a dedicated dehumidification system that is essential to keep relative humidity below 60%. Excess humidity can lead to condensation, mould growth, and structural damage. Advanced systems can capture and reuse heat from the dehumidification process to warm the pool water or air.

 

Also important is air distribution and the HVAC system should use ducting to ensure even air circulation, especially targeting cold surfaces like windows and glazed walls to prevent condensation. We position the air supply and returns positioned to collect moisture-laden air across the pool's surface and to send these to the glazing.

 

A high-quality vapor barrier is necessary in the roof and walls to prevent moisture from entering the building structure, which can cause significant damage. All joints must be completely sealed. Structural considerations The structure supporting an indoor pool must withstand heavy loads, high humidity, and corrosion and the pool shell must be properly insulated to meet regulations and minimize heat loss, which improves energy efficiency. This also prevents "cold bridging," where insulation gaps cause localized condensation.

 

Within the pool hall, we use materials specified for exterior use, as they can withstand the moisture and chemical exposure of a pool environment. Waterproof render, tiling, and treated timber are suitable, while plaster and plasterboard are not. All specified glazing consists of sealed double- or triple-glazed units with thermal breaks to prevent condensation. Window frames are made of corrosion-resistant materials like PVC or aluminium.
