Ventilation Systems

Types of Ventilation Systems in Buildings

Ventilation in buildings and other homes is essential to guarantee maximum livability and comfort, thus achieving the best conditions for housing.

In addition, ventilation in a building is essential to achieve thermal comfort, optimize the durability of materials and enhance healthy environments. And not only that, the good transformation of air in any construction is essential to renew oxygen, the elimination of unpleasant odors and pollutants and thus avoid condensation and, consequently, the appearance of any type of humidity .

Mainly, ventilation aims to ensure an optimal exchange of the air we do not want for a more renewed and purified one, thus guaranteeing that the inhabitants enjoy a healthy environment and a house that works and conserves itself better.

Thus, the Technical Building Code considers the need for buildings to have adequate ventilation systems in order to eliminate contaminants that are routinely produced during use. These ventilation systems must provide a sufficient flow of outside air in addition to guaranteeing the extraction and expulsion of air contaminated by pollutants.

According to the current regulations of the construction sector , there are two large groups of ventilation that are contemplated in the realization of the facilities of a building, regardless of the sector to which they belong: hybrid ventilation and mechanical ventilation. Let’s see then what each of them consists of.

Hybrid ventilation

It is a type of controlled ventilation in which, when the ambient pressure and temperature conditions are favorable, the renewal of the air occurs through natural ventilation. In contrast, when conditions are unfavorable, forced ventilation is activated by mechanical extraction. For this system to function properly, it must be designed with the requirements of a natural system so that the installation generates the minimum possible pressure drop and small pressure differences can move the air.

Forced ventilation

This system is the type of ventilation (also called mechanical or artificial) in which air renewal occurs through the use of electro-mechanical devices. In this case, the flows are not affected by the weather conditions. In addition, the pressure differences are generated by the extractors so that they can be higher and more controllable, a factor that offers a clear advantage in design and installation. This system allows a lot of flexibility in the design of the ducts since there are no length limits or restrictions on the horizontal branches.
