What moisture control technique helps manage energy efficiency?

Sealing and insulating building envelopes is the correct choice because this technique directly impacts both moisture control and energy efficiency in buildings. When a building envelope is well-sealed and insulated, it prevents unwanted air infiltration and exfiltration, which can lead to moisture accumulation within walls and attic spaces. This not only helps to control moisture levels but also reduces the energy required for heating and cooling. By minimizing thermal bridging and maintaining consistent indoor temperatures, it ensures that heating and cooling systems operate more efficiently, leading to lower energy consumption.

Using appropriate sealing and insulation materials contributes to a more comfortable indoor environment, prevents mold growth, and reduces the risk of structural damage from moisture. This practice is fundamental in energy-efficient building design and construction, making it an essential component of moisture control strategies.
