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. ⠀⠀⠀⠀⠀⠀⠀⠀

Air exchange in a private house

What should be the air exchange in a private house ⠀
⠀
According to the above document, the minimum air exchange values should be as follows: ⠀
⠀ 🔸 in rooms with a constant stay of people (this is one in which people stay for at least 2 hours continuously or 6 hours in total during the day) the air volume should completely change once an hour ⠀
🔸 at least 60 m3 of air should be removed from the kitchen per hour ⠀
🔸 from the bathroom, bath, shower, toilet - 25 m3 of air per hour ⠀
🔸 in other rooms the recommended rate of air exchange is not less than 0.2 room volume per hour. ⠀
⠀
📍 The following are recommendations from other documents that you can rely on when calculating the ventilation system in your home: ⠀
⠀
Moscow city building codes 3.01-01 Residential buildings: ⠀
🔶 Air exchange - at least 30 m3 / h per person ⠀
⠀
Territorial construction standards OVK-2000 MO TSN 41-302-2000⠀
🔶 Air exchange - At least 30 m3 / h per person ⠀
RESIDENTIAL BUILDINGS SNiP 2.08.01-89⠀
🔶 Air exchange - 3 m3 / h per 1m2 of residential premises ⠀
⠀
SNiP 41-01-2003 HEATING AND VENTILATION ⠀
Air exchange - Residential apartments with total area for 1 person: ⠀
🔶 over 20 m2 room with natural ventilation 30m3 / h, without natural ventilation 60 m3 / h ⠀
🔶 less than 20 m2 a room with natural ventilation of 3 m3 / h per 1 m2 of living space ⠀
⠀

Forced ventilation

Is forced ventilation necessary? ⠀
⠀
Is it necessary to arrange forced ventilation in a private house in order to provide the recommended air exchange indicators from the point of view of regulatory documents? ⠀
⠀
⚠ Recall, the current SanPiN 2.1.2.2645-10 prescribes to have windows and windows for ventilation, для
it is only about natural ventilation. ⠀
⠀
4.7. Natural ventilation of living quarters should be carried out by air inflow through vents, transoms, or through special openings in window sashes and ventilation ducts. Exhaust duct openings should be provided in kitchens, bathrooms, toilets, and ovens. ⠀
At the same time, the minimum volume recommended in a number of documents ⠀
air per person should be at least 30 m3 / h in 1 hour. ⠀
⠀
⠀
🌪 Updated version of SNiP 4101-2003 (introduced from 01.01.2013): 30 m3 per person or 0.35 volume per hour ⠀
⠀
Thus, if the area of the living room is large enough, and for each person in it from 10 to 20 square meters, the organization of supply and exhaust ventilation according to the current ⠀
regulations are not vital. But if the room per person accounts for less than 20 square meters, forced ventilation is already urgently needed. ⠀
⠀
⠀
🌫 So, a bedroom with an area of 20 meters, in which two adults spend the night, can still do without forced ventilation. A bedroom of 18 meters is no longer there; airing alone will not cope with ventilation tasks. And small bedrooms in small cottages are done quite often. ⠀
⠀
🌟 Conclusions ⠀
⠀
According to current regulations, in houses where most of the bedrooms are less than 20 square meters, a forced ventilation device is necessary. It is also highly recommended to arrange it in large cottages with an area of more than 400 square meters. ⠀
⠀
But in a number of other cases, the “minimum amount of air” will not provide a comfortable life in a secluded house. ⠀
