Which of the following is a moisture control strategy?

• A. Install skylight
• B. Add carpet
• C. Dehumidification
• D. Build a pond

Answer: (C)

Moisture control in buildings is about keeping humidity within safe levels to prevent condensation, mold, and material damage. Dehumidification directly lowers the amount of water vapor in the air, reducing relative humidity to a safer, more comfortable range. This helps make spaces drier, especially in damp areas like basements or in humid climates. It’s a practical, active method that can work in tandem with ventilation and proper sealing to manage moisture effectively. The other options don’t address humidity in the same way: a skylight changes daylight and heat from the sun but doesn’t reduce moisture; adding carpet can influence how moisture is felt and handled on floors but isn’t a deliberate humidity-control measure; building a pond adds water and can raise moisture risks rather than control them.
