# How is the calculation of ventilation right?

It is difficult to perform calculation of ventilation? It is no secret that without ventilation, can not exist, no room, whether it’s a regular apartment or a huge production. In order to properly organize, it is necessary to conduct a series of calculations. It may seem too complex or confusing, but only at first glance.

## How to do this procedure?

If you do everything in stages, there is nothing difficult that will be. For starters, we should not forget that the ventilation can be natural, i.e. that which is performed by opening Windows and doors, through cracks and pores in walls and air handling.

Moreover, natural ventilation is possible only in case if the building has channels-air ducts through which air can freely circulate. More warm goes up and cold goes down, as is circulation. In order to provide to the building fresh air duct and removal of waste, it is necessary to consider that at the stage of construction. We should not forget that, since the building without sufficient ventilation will become simply uninhabitable.

For starters, you need to understand how much air you need for a home. When designing it is important to consider what you will use those or other premises. If the house or apartment, you must arrange it so that fresh air came in first in the bedrooms, living and kids, and then, passing through the corridors, went out through the most contaminated – for example, a bathroom.

This will help to eliminate unpleasant smell in the room plan and provide a constant flow of fresh air to places of sleep and rest. First of all, you should determine the volume of air that needs to come into the room. It will help the norms of the SNiP, where the air exchange is calculated depending on how many people are planned in the room. According to these standards, the volume of air diverges in the range from thirty to sixty cubic meters.
