If natural ventilation is not adequate then an artificial ventilation system which will circulate air through a room “by means of a mechanical apparatus which forces air into or extracts air from such room” is mandatory. A mechanical ventilation system is not required where natural ventilation openings comply with the requirements of Section 402.2 and are permanently open or have controls that prevent the openings from being closed during occupancy. The types of ventilation covered includes, mechanical, passive stack, background and purge (rapid). That is why the Building Code has included requirements for mechanical ventila­ tion for many years. Colt's mechanical smoke and heat ventilation systems extract up to 6 kbm/sec of smoke and fumes per unit from the building when used as smoke and heat ventilation systems. These fixtures disinfect air as it circulates from mechanical ventilation, ceiling fans, or natural air movement. Code Ventilation Requirements midity levels within the dwelling are also a concern. WHERE USED There are proprietary mechanical ventilation systems available that exhaust odours and steam from wet area rooms and fixtures. A windowless room can serve many purposes. Other types of system are not considered. • Look for leak(s) with a hand held leak detector. Limit values for humidity and air quality, e.g. If I understand correctly, a boiler room in a residential home requires a vent for fresh air.
