How many meters should the clear height of the room be no less than?

1. The indoor clear height of the bedroom and living room (hall) should not be less than 2.4m, the local clear height should not be less than 2.1m, and its area should not be greater than 1/3 of the indoor usable area.

2. When using the space in the sloping roof as a bedroom and living room (hall), the indoor clear height of 1/2 area should not be less than 2.1m.

3. The indoor clear height of kitchen and bathroom should not be less than 2.2m. The clear distance between the lower surface of the horizontal drainage pipe in the kitchen and bathroom and the floor and ground shall not be less than 1.9m, and shall not affect the opening of doors and sashes.

the concept of room clear height

the room clear height refers to the vertical distance between the floor or ground and the bottom of the upper floor or ceiling. The relationship between clear height and floor height can be expressed by formula: clear height = floor height-floor thickness. That is, the difference between the floor height and the floor thickness is called "clear height".

Influencing factors of room height

The main factors influencing room height are:

1. Requirements for human activities and the use of furniture and equipment: the clear height of the room should be no less than 2.2m.

2, lighting, ventilation and other health requirements: the height of the room should be conducive to natural lighting and natural ventilation to ensure that the room has the necessary health conditions.

in order to ensure the necessary sanitary conditions of the room, the necessary gas capacity of the room should also be considered.

the specific value is related to the use of the room, such as 3 ~ 5m3/person for classrooms in primary and secondary schools and 4 ~ 5m3/person for audience halls in theaters. The air volume required by the room also affects the indoor clear height.

3. Indoor proportion and space perception: whether the indoor space is closed or open, large or small, and whether the proportion is coordinated or not will give people different feelings.
