What does fenestration refer to in architectural terms?

Fenestration specifically refers to the design and arrangement of windows and doors in a building. This term is crucial in architecture as it impacts not only the aesthetic appeal of a structure but also its functionality, including factors like natural light, ventilation, and thermal performance. The placement, size, and type of windows and doors can significantly influence the overall design and efficiency of a building. By effectively managing fenestration, architects can enhance the livability and sustainability of their designs, ensuring they meet the needs of occupants while addressing environmental considerations. Additionally, the strategic use of fenestration can contribute to energy efficiency by maximizing natural light and minimizing heat loss.
