Living in a high-rise apartment in a coastal city like Dubai offers stunning views and luxurious living, but it also comes with unique challenges, particularly when it comes to humidity control. A recent investigation of a high-rise residence on The Palm, Dubai, uncovered several factors contributing to elevated humidity levels, providing valuable insights for property owners, managers, and residents dealing with similar issues.
Key Findings from the Investigation
The unit was found to operate under positive pressure, meaning more air was being pushed in than removed. This caused air to escape through gaps in windows, doors, and shaft penetrations, allowing humid air to infiltrate the space. The fresh air supply duct was delivering air with a mixing ratio of 13.06 g/kg, far exceeding the acceptable range of 9.0 – 10.0 g/kg. This suggests that the Fresh Air Handling Unit (FAHU) may not be effectively treating or pre-cooling the air, leading to elevated indoor humidity levels.
Contributing Factors to High Humidity
Several other issues were identified during the inspection:
- Improperly sealed doors: Gaps in aluminum doors allowed humid air to infiltrate, especially during summer.
- Unsealed EPDM lining: Damaged and unsealed sections of the moisture barrier allowed air infiltration.
- Moisture damage on walls: Unsealed gaps on balconies led to water infiltration, leaving calcium deposits and increasing humidity.
- Gaps in ceiling lights and shaft penetrations: These minor gaps served as entry points for humid air, contributing to condensation over time.
Recommendations for Humidity Control
To address these issues, the following steps were recommended:
- Inspect and optimize the FAHU: Ensure the system is effectively treating and pre-cooling the air.
- Seal gaps in doors and EPDM lining: Properly seal all overlaps and replace damaged sections to prevent air infiltration.
- Address moisture damage: Clean and seal gaps in aluminum cladding, remove calcium deposits, and allow walls to dry thoroughly.
- Seal shaft penetrations: Use fire-stop sealant to close gaps in shafts and prevent air and moisture infiltration.
Why This Matters for Property Owners
For property owners and managers in coastal areas like The Palm, Dubai, regular inspections and maintenance are crucial to prevent humidity-related problems. High humidity can lead to mold growth, structural damage, and poor indoor air quality, impacting both the property’s value and residents’ health.
By addressing these issues proactively, you can ensure a healthier, more comfortable living environment and protect your property from long-term damage. If you’re dealing with humidity issues in your high-rise residence, consider consulting with professionals to conduct a thorough inspection and implement effective solutions.
