The building envelope is designed to resist which of the following?

Light, heat, and noise transfer
Air and water
Structural integrity
Flame and smoke

The correct answer is: Air and water

The building envelope serves as a critical barrier between the interior and exterior of a structure, designed specifically to manage the flow of air and water. This includes resistance to air leaks that can lead to undesirable drafts and loss of heating or cooling, ultimately affecting energy efficiency. Additionally, proper water management through the building envelope is essential to prevent moisture intrusion, which can result in mold growth and damage to structural elements. The choice to focus on air and water management highlights the dual purpose of the envelope in protecting the building from environmental elements while also ensuring the comfort of occupants. Effective design and materials used in the building envelope contribute significantly to a structure's overall performance and durability. Therefore, understanding its role in resisting air and water is fundamental in construction practices and codes.
