SNiP 41-01-2003 or Construction Norms and Rules of the Russian Federation were developed by the State Committee for Construction and Housing and Communal Services. The document contains a special section dedicated to the ventilation of residential and public buildings. Updated SNiP ventilation of residential and public buildings include parameters that are consistent with the requirements of fire, environmental and sanitary safety. In accordance with the requirements of modern construction, the section on compulsory ventilation in living quarters and public as well as air conditioning. The innovations relate to smoke control ventilation of residential buildings.
Applications
SNIP ventilation of residential and public buildings is used in the construction of ventilation, air conditioning, heating and heat supply in buildings, except for:
- shelters, mines, storage facilities for explosive substances, facilities for working with radioactive substances,
- electrical installations, buildings with vacuum cleaner installations.
When compiling SNIP for ventilation of residential buildings, GOSTs were used for sanitary requirements for noise, air parameters and microclimate in buildings. And also SNiP about fire safety, protection from heat, noise, building climatology.
Air parameters according to SNiP
According to SNiP ventilation of residential buildings, the air temperature in residential premises during the unused period should be at least +15 degrees, in household premises at least +12 degrees, in production workshops at least +5 degrees.
Ventilation systems of residential buildings must ensure, within the established norms, the speed of air movement in apartments, relative humidity.
For the warm season, the temperature and humidity in the living quarters are not standardized.
Purpose of air ventilation
Ventilation and air conditioning are used to achieve the air and microclimate values required for a given room.
Supply ventilation is installed if:
- Natural ventilation in residential premises is not able to provide the necessary air parameters;
- There is no way to organize natural ventilation.
According to SNiP, ventilation of residential premises can be planned as a combined type using natural draft for blowing out or inflowing air. When calculating the natural ventilation of residential premises, the calculated temperature difference is 5 degrees.
In accordance with SNiP ventilation of residential premises, systems are equipped for premises located within the boundaries of one fire compartment. It is allowed to combine residential and administrative premises into one fire compartment.
