Construction industry is now focused on building ecological and energy-efficient houses. Thanks to this, their owners do not contribute to the production of harmful fumes, and their bills for electricity, water or heating are not high. All windows and doors should be well sealed so that they do not cause senseless heat loss. Find out which type of ventilation will be the best solution for your home
Adequate air circulation in your home is essential so that it doesn’t get too humid inside. Regular ventilation also has many health-promoting advantages and is very beneficial for household members. Lack of fresh air at different temperatures damages the building and has a negative impact on our health and well-being. Check how to install mechanically assisted ventilation in your home. Lost natural ventilation draught, called gravitational often requires additional stimulation. Then the best way is to install supply or exhaust ventilation, or use a system that combines these two types of ventilation. Learn how ventilation works in an energy efficient house and decide which solution will work best for you
Ventilation should not cause significant heat loss. Each building and room requires a different amount of air. The living areas should have a constant supply of fresh air from outside. It is also important to ensure the flow of air between rooms, which is why in doors you can often find air vents at the bottom slat. In our home, there must be an adequate supply and exhaust of air from the room. How to create a system that meets all these conditions?

Many engineers and architects recommend gravity ventilation. This type of ventilation has vertical exhaust ducts in chimneys and vents in windows or walls. The mechanism that drives this solution is the difference in temperature, pressure and density of the air that is inside and outside the building. This is a solution that works great in our climate. During the summer, a gravity ventilation system works a little less well
Supply air ventilation
In some low-energy houses we can meet with a supply air ventilation system, whose main purpose is to provide the building with fresh air from outside. Fans, which are installed in the rooms, help here. Excess air is removed through chimney openings and windows. Unfortunately, this system makes us feel unpleasant cold more often in the house.
The second option is an exhaust ventilation system, which also requires the installation of fans to remove excess air from the building. The best way to do this is with a hybrid system that does the two jobs of supply and exhaust. It is important that the house has openings through which excess air can be exhausted. For this solution to be successful, the ventilation components must be exposed.
