Knowra Building envelope Building envelope The physical boundary separating a building’s interior from its surroundings, formed by elements such as walls, roofs, windows, doors, and foundations. It controls exchanges of heat, air, moisture, light, and sound.
Building insulation : Materials and systems that reduce heat transfer through a building’s components. Insulation slows heat flow across the envelope’s walls, roofs, and floors.
Building facade : The exterior face of a building, especially its visible walls and openings. The facade is the envelope’s most visible vertical portion.
Building energy efficiency : The ability of a building to provide services while using relatively little energy. Reducing envelope heat loss and solar gain can lower heating and cooling demand.
Mass wall : A thick wall that uses substantial material mass to store and moderate heat. Unlike lightweight layered enclosures, mass walls rely heavily on thermal storage.
Building pathology : The investigation of defects, deterioration, and failures in buildings and their causes. It diagnoses enclosure failures such as leaks, decay, and cracking.
Air barrier : A continuous layer designed to limit uncontrolled airflow through a building enclosure. Its continuity determines whether air leaks through the envelope.
Roof : The upper covering of a building that shelters its interior from weather. Roofs form a major, weather-exposed part of the envelope.
Passive house : A building standard emphasizing very low energy demand, airtight construction, and high-performance components. Its performance targets rely on a carefully designed, continuous envelope.
Rainscreen : A cladding system with a drained, ventilated cavity behind its outer layer. It manages rain differently from face-sealed cladding by providing drainage and drying space.
Mold : Fungi that grow as multicellular filaments, often on damp building materials. Persistent envelope moisture can create conditions for indoor mold growth.
