Which term is described as the arrangement of openings like windows in a building?

• A. Fenestration
• B. U-value
• C. SHGC
• D. R-value

Answer: (A)

Fenestration is the arrangement of openings such as windows, doors, and skylights in a building. It covers how many openings there are, their sizes, shapes, spacing, and alignment across surfaces. This design choice shapes daylighting, views, ventilation, and solar heat gains, all of which influence comfort and energy use. A well-planned fenestration balances letting in light and warmth with controlling heat loss or gain, often considering orientation and shading to optimize performance. The other terms relate to how well a building or its components conduct heat, not where openings are placed. U-value measures how easily heat transfers through a component, SHGC indicates how much solar heat actually passes through glazing, and R-value describes insulation resistance.
