Air infiltration refers to the unintentional or accidental introduction of outside air into a building, typically through cracks in the building envelope, leading to increased energy consumption and reduced indoor air quality. Managing air infiltration is crucial for energy efficiency, occupant comfort, and maintaining a controlled indoor environment.

The building envelope is a critical component of a structure, acting as a barrier between the interior and exterior environments, and plays a significant role in regulating energy efficiency, comfort, and durability. It encompasses all elements of a building that separate the conditioned space from the unconditioned space, including walls, roofs, floors, windows, and doors, and must be carefully designed to manage heat, air, and moisture transfer effectively.

Energy efficiency refers to using less energy to perform the same task or produce the same outcome, thereby reducing energy waste and lowering energy costs. It is a crucial component in combating climate change and enhancing energy security by minimizing the environmental impact of energy consumption.

Energy Efficiency

Occupant comfort is a holistic measure of how well a built environment supports the well-being and satisfaction of its users, encompassing thermal, acoustic, visual, and air quality factors. It is crucial for designing spaces that enhance productivity, health, and overall quality of life, requiring a balance between subjective perceptions and objective environmental parameters.
