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. ⠀
