Openings in side walls that let light and a cooling flow of air into the central interior space are called: <u>ventilation or infiltration</u>.
Ventilation brings fresh air from outside into a structure or space and distributes it there.
Flow of air inside a structure and air exchange with the outside, whether planned or inadvertent, are referred to as ventilation and infiltration, respectively. They are both crucial factors to take into account when designing healthy buildings that also reduce heat loss.
Infiltration results in heat loss during the winter because warm inside air is replaced by cooler outside air. Energy expenses will rise as a result of the heating system operating longer and more frequently. As more humid air is brought in from the outside during the summer, infiltration might potentially result in mould conditions.
