What does fenestration refer to in building design?

Fenestration in building design refers to the arrangement and design of windows and doors in a structure. This concept plays a crucial role in determining natural light, ventilation, and aesthetic appeal of buildings. When considering option B, the integration of louvered walls and continuous windows captures the essence of fenestration as it implies a thoughtful approach to combining these elements for effective light management and airflow.

The mention of louvered walls suggests a design that maximizes ventilation while still providing opportunities for natural light to enter through windows, which is a core principle of fenestration. Such integration not only enhances the building's functionality but also contributes to energy efficiency and overall occupant comfort. Understanding fenestration as a holistic approach to window and door design reinforces its significance in both architecture and environmental impact considerations.
