What are the design requirements for ventilation design of modern high-rise hotel buildings?

The ventilation of ordinary houses generally requires natural ventilation, and there is no mechanical ventilation requirement except kitchen and bathroom, so there is no ventilation air volume parameter of houses. The relevant specifications of natural ventilation opening area and other requirements are as follows:

Code for Residential Building GB 50386—2005

7.2.4 Houses should be naturally ventilated, and the ventilation area of each house should not be less than 5% of the ground area.

Code for Residential Design (GB 50096- 1999) (2003 edition)

5. 1.4 The bedroom and living room (hall) should have natural ventilation that circulates directly with outdoor air. Ventilation measures shall be taken for one-way houses.

5. 1.5 The ventilation area of a naturally ventilated room shall meet the following requirements:

1 The ventilation opening area of bedroom, living room (hall) and bathroom should not be less than 1/20 of the building area of this room.

2 The ventilation area of the kitchen should not be less than110 of the building area of the room, and should not be less than 0.60m2 ..

5. 1.6 The bedroom, living room (hall) of the residence in severe cold area should be provided with ventilation facilities, and the kitchen and bathroom should be provided with natural ventilation channels.

Supplementary answer:

In fact, there is no provision for mechanical ventilation in these standards and specifications. Ventilation in residential buildings is solved by opening windows. The code only specifies the areas that need natural ventilation, and does not say that "insufficient natural ventilation can be supplemented by mechanical ventilation", because if natural ventilation is insufficient, it violates the mandatory code and is strictly prohibited by law. Residential Building Code is the first and only architectural design code with mandatory provisions. As for some enthusiastic friends, "the number of air changes per person per hour is a certain number", it should only be the accumulated experience value during public construction, which can not be found in the formal design specification.
