Whether you are building a new home or modifying an existing one, you need to understand the different types of self-draft ventilation. This is important because it can affect the performance of your livestock building. In addition, it will save you substantial money. You can find a variety of products to help you with this process. Knowing the different types of ventilation you have in your home will help you choose the best ventilation product for your needs.
The types of self-draft ventilation in your home can include supply air, exhaust air, and natural draft ventilation. All of these systems work by pulling air into your house and pushing it out. The ventilation rate will vary depending on the speed of the wind and the volume of your building.
Supply air is the air that enters the house. This air is usually warm and moist. It leaves the house as a positive pressure. It is called the stack effect because it is caused by the differences in temperature, pressure, and buoyancy between the inside of the house and the outside. It causes condensation, which can lead to mould problems. Condensation can also cause damage to the building envelope.

Mechanical ventilation, on the other hand, is caused by designed openings in the building envelope. It includes exhaust fans, heat recovery ventilators, and range hoods. These devices are used to remove air from pollutants-generating rooms. The system uses ducting to force air from these rooms through the house. The air exits through the windows and doors. This type of ventilation is often used in buildings built after 1980. However, it is rarely used due to the technical limitations.
Typical balanced ventilation systems include two fans to pull air into the house and one to exhaust it. Each fan is linked to a duct system, and the fan can also be located in the attic. This type of ventilation can be used to supply air to living rooms, bedrooms, and other rooms that need fresh air. It can also be used to exhaust air from moisture-generating rooms. It can also remove pollen and other contaminants from the air. These systems can be very effective. However, they are more expensive to install.
Natural draft ventilation, on the other hand, is caused due to pressure differences between the inside of the house and the outside. During the winter, when the temperature inside the building is colder than the outside, air tends to enter the building upwind. This air then leaves the building downwind. The amount of air movement from natural ventilation varies greatly from season to season. Some of the functions of natural ventilation are less effective in the spring or fall. Other functions can also be affected by construction changes, heating system replacement, and additional insulation.
Eave vents are another type of ventilation system that can be used to meet your eave opening requirements. These vents can be open spaces between trusses or between the rafters. They should be at least four inches wide to allow for air movement. They should be able to withstand the force of direct wind.
