Envelope: The Surface Wrapping

Building envelope refers to the physical boundary that separates a conditioned interior environment from an unconditioned exterior environment of a building. It includes all the exterior elements of a building, including the walls, roof, windows, doors, and foundation, as well as the insulation and sealing materials used to assemble them. A well-designed building envelope can help maintain a comfortable and healthy indoor environment while reducing energy consumption and mitigating the impact of external factors such as heat, cold, wind, rain, and noise. It plays a crucial role in achieving energy efficiency goals and improving the sustainability and resilience of buildings.
