The space between the indoors of the building and outdoors of the outer world is called a vestibule. Though they are an important part of the building, they do constitute the hardcore structure of the building. It provides a converging space that can be put to use for multiple functions. All the architectural buildings have a defined vestibule that adds to the beauty of the building.
A commercial building has vestibules installed usually on the entrance doors. The main motive of a commercial vestibule is to reduce the rate of air infiltration into the space. This will ensure energy conservations and will also provide better comfort to its users. A vestibule is treated as an entrance court in a commercial building. The builders are of the opinion that it lends a formal touch to the overall look.
A vestibule can be used in a number of ways. They are often used to achieve energy efficiency as they lock in the building temperature, avoiding the outside weather fluctuations. They also help in cutting down noises. A vestibule can trap a lot of dust and needs to be kept organized. The proportion of a vestibule must be in tandem with the construction of the entire building.
