Ventilation of a space may be made by natural process or by mechanical method. 406 refers to both natural ventilation and mechanical ventilation. Discuss Ventilation requirements for kitchen and utility room extension? Mechanically ventilated facilities/areas: where mechanical ventilation is available, negative pressure should be created to control the direction of airflow. Generally, natural ventilation should be organized so that doors and windows relate to one another in such a way that the room will be effectively ventilated, and it should be at least five percent of the floor area of the room (or at least 0,2 square metres if the room is very small). Meaning of Ventilation: Ventilation is the process of supplying fresh air into a closed space or the removal of foul air from inside of a closed space. In holiday homes, or buildings that peo… Another solution, which needs designing in from the start, is passive ventilation. The Canadian National Building Code (NBC) requires residential houses to mechanical ventilation system capable of providing at least one half (0.5) air changes per hour during the heating season to avoid chimney back drafting.
