Understanding U-Value: The Foundation of Energy-Efficient Envelopes

© ArchDailyMuch more than merely as a protective skin, the building envelope functions as a thermal regulator that influences operational energy demand, indoor comfort, and long-term efficiency. And before renewable systems or mechanical strategies are introduced, performance begins in section. The way walls, roofs, windows and floors are layered determines how much heat is lost in winter, gained in summer, and ultimately how much energy a building consumes. At the center of this evaluation
