“Mechanical ventilation” refers to any system   that uses mechanical means such as ventilation fan, to introduce outdoor air   to a space when natural ventilation mode cannot be achieved during normal and   fire emergency situations. This includes supply ventilation, exhaust ventilation,   pressurisation, smoke purging, mechanical engineered smoke control systems,   balanced systems that consist of both supply and exhaust ventilations, etc..

1.4.113 Pressurisation

“Pressurisation” refers to a mechanical ventilation system that introduce positive differential pressure to a space/room to prevent smoke ingress during a fire emergency.

1.4.114 Capsule hotel

“Capsule hotel” refers to a type of hotel where the bed spaces are enclosed individually. Each bed space is considered as a capsule and not as a loose furniture or fitting. The capsule has the following characteristics:

a. access opening to the bed space can be fitted with doors, curtains or other materials or left open; and

b. the bed space is provided with its individual electricity supply for amenities such as lighting, power points, TV and other amenities.
