Answer 2

Answer:

Ventilation moves outdoor air into a building or a room, and distributes the air within the building or room. The general purpose of ventilation in buildings is to provide healthy air for breathing by both diluting the pollutants originating in the building and removing the pollutants from it (Etheridge & Sandberg, 1996; Awbi, 2003).

Building ventilation has three basic elements:

ventilation rate — the amount of outdoor air that is provided into the space, and the quality of the outdoor air (see Annex D);

airflow direction — the overall airflow direction in a building, which should be from clean zones to dirty zones; and

air distribution or airflow pattern — the external air should be delivered to each part of the space in an efficient manner and the airborne pollutants generated in each part of the space should also be removed in an efficient manner.

There are three methods that may be used to ventilate a building: natural, mechanical and hybrid (mixed-mode) ventilation.
