One of the aspects of a newly-built house is ventilation. It makes everyone who enters the home feel comfortable by its pleasant air.

Types of Ventilation System

Generally, in Natural Ventilation, every room has been ventilated in harmony with nature. It is a ventilation method that supplies fresh atmospheric air into indoor and removes unpleasant stagnant air from indoor space. Importantly, we do not use any mechanical devices or components in Natural Ventilation. Driven by natural forces like wind, external air gets into the house, supplying proper airing to the dwellers. In this manner, the Natural Ventilation system works.

Well-Designed ventilation can do more to a house. In the summertime, it will keep the room cool. Similarly, it will warm the room in the wintertime. Therefore, we can achieve the goal of the ventilation system at zero cost when the airing is natural. 

Natural ventilation occurs when the opening of the doors and windows. It is unpredictable. Moreover, it does not remove moisture and pollutants properly. Nowadays, people do not prefer this method because they want their home to be more energy-efficient. Also, one cannot expect uniformity of airflow through the natural ventilation system.

Mechanical Ventilation (Exhaust-only)

This type of ventilation is a reasonably common plan. In the room, small exhaust fans, typically in bathrooms and kitchens, operate to exhaust musty air and moisture. This ventilation method takes in fresh air either through air-leakages and other cracks. Besides, the system will suck in fresh air through inlets that are intentionally planned for this specific purpose. A benefit of the exhaust only mechanical airing is low cost and simplicity. A drawback of this model, as well, is to have negative pressure in houses which we do not want. 

Mechanical Ventilation (Supply-only)

In this plan, a fan takes in the fresh air. And musty air gets out through air leakage sites and cracks in the house. The air supply can be dispersed to a location through ducts. This type of airing system pressurizes a building or house. This plan can be good to prevent contaminants like radon from passing in the house. But the house or the building will be at risk when moisture-laden air moves into ceiling cavities and wall where moisture and condensation problem can happen. 

Balanced Ventilation

Balanced ventilation is much better at straining pollutants from the air. Plus, it is good at maintaining pressure. This type of airing system brings in fresh outside air into the home. At the same rate, the system exhausts musty inside air from the home. 

In this method, separate fans drive both exhaust and inlet flows. On the whole, the balanced airing system will be either ducted or point-source. A balanced system provides much better airing. Moreover, this system lets us regulate where the fresh air comes from and where the supply of fresh air should be.
