Fenestration is best described as which of the following?

• A. An opening in a building such as windows or doors
• B. Grille
• C. GRD
• D. IP

Answer: (A)

Fenestration is the openings in a building envelope through which air, light, and sometimes sound move. The best description is an opening in a building such as windows or doors because that directly captures the concept of an opening that connects the indoor and outdoor environments. A grille is something installed within an opening to regulate airflow or for decoration, not the opening itself, and the other terms do not describe openings in the building envelope.
