Building Envelope

Definition

The building envelope includes all external building materials, windows, and walls that enclose the internal space of a building.

Purpose

The building envelope serves multiple functions: it protects the interior from external weather conditions, regulates temperature and humidity, provides structural support, and contributes to the aesthetic appearance of the building. It plays a crucial role in energy efficiency and occupant comfort.

Examples of Use

1. Insulation: Proper insulation within the building envelope helps maintain indoor temperature and reduce energy costs.
2. Windows and Doors: High-performance windows and doors improve thermal efficiency and reduce air leakage.
3. Weatherproofing: External cladding and weatherproof membranes protect the building from rain, wind, and other environmental factors.

Related Terms

• Thermal Envelope: The part of the building envelope that provides thermal insulation and air sealing.
• Facade: The exterior face of a building, often involving the aesthetic design elements of the building envelope.
• Building Shell: Another term for the building envelope, emphasizing its role in enclosing the internal space.

Notes

Maintaining and upgrading the building envelope can significantly enhance a building's energy performance and comfort levels. Regular inspections and maintenance are necessary to address wear and tear, especially in harsh climates.
