Proper ventilation

Laws and regulations on ventilation in a private country house ⠀
⠀
Owners of country houses, independently designing ventilation systems, often find it difficult to determine how much air exchange to navigate in the calculations. In this article, we will consider the basic regulations governing the ventilation device in a country house, consider the existing SNiPs and SPs, and find out what they mean in practical terms. ⠀
⠀
📜 The main document that regulates the installation in a private country house of all engineering systems, including ventilation, is SP 55.13330.2016 “Residential single-family houses. Updated edition of SNiP 31-02-2001 ".⠀
⠀
⠀
It states that the ventilation system must be such as to cope with the uniform flow and distribution of clean fresh air around the house. Below we will talk about the recommended values of air exchange. ⠀
⠀
☝ From SP 55.13330.2016 it follows that the ventilation system can be: ⠀
⠀
✔ natural ⠀
✔ with mechanical induction of inflow and removal of air, including combined with air heating ⠀
✔ Combined ⠀
⠀
At the same time, air must be removed from: ⠀
⠀
- kitchens ⠀
- toilet ⠀
- bathroom ⠀
- bathroom ⠀
- shower ⠀
⠀
From the rest of the premises, air is removed as necessary. ⠀
⠀
⚠ If there may be unpleasant odors in the room, or harmful substances may appear in the air, they must be removed from the house without entering other rooms and utility rooms. ⠀

🗣 Client: And explain to me why it is impossible to make a riser alone in the kitchen and / or? ⠀
⠀
⠀
@energo_doma: It will not smell as intended. Few people will like it when it smells of borsch in the shower, in the kitchen with shampoo. ⠀
⠀
The document does not say anything about the mandatory forced ventilation device; only “ventilation openings” are mentioned in it. Quote SP 55.13330.2016: ⠀
⠀
To ensure natural ventilation, it should be possible to ventilate the premises of the house through windows, windows, transoms and other ventilation openings. ⠀⠀⠀⠀⠀⠀⠀⠀
