What is meant by 'building enclosure' in construction?

The concept of 'building enclosure' refers to the outer structure that separates the indoor environment from the outdoor environment. This includes elements such as walls, windows, doors, and the roof, all of which work together to protect the interior space from external weather conditions, provide thermal insulation, and contribute to energy efficiency. A well-designed building enclosure is crucial for maintaining comfort within the structure and minimizing energy costs.

By creating a barrier between the interior and exterior, the building enclosure plays a vital role in controlling factors like air infiltration, moisture management, and heat transfer. This ensures not only the comfort of the occupants but also the longevity of the building materials used.

While the foundation layer, interior layout, and roof design are essential components of a building, they do not encompass the full scope of what a building enclosure entails. The enclosure specifically focuses on the exterior façade that interacts with the environment, making the correct choice about the outer structure clear.
