How Important is Ventilation?

Ventilation is a term used in architecture and construction to describe the introduction of fresh air into a building without allowing it to escape. This is achieved through means such as windows, vents, and doors. Ventilation is needed in all buildings as a way to keep people and materials healthy and comfortable.

It can be a bit of a revelation to some when they learn how important ventilation is for the health and comfort of building occupants. Without proper ventilation, the air quality in your home will suffer greatly. It keeps air flowing through the home, eliminating contaminants, odor, and moisture. 


Types of Ventilation Systems

Natural Ventilation

This type depends on natural factors like wind and thermal buoyancy to work. There are three factors that affect natural ventilation; climate, human behavior, and the design of the building

This can be achieved through the proper positioning of windows, doors, chimneys, etc. If these purpose-built openings work the way they are supposed to, energy consumption costs should decrease anywhere between 20% - 25% for an average household. 

If buildings were not constructed and designed with good ventilation to begin with, then often the only way to achieve suitable ventilation is thought some form of office refurbishment project

It should be taken into consideration that the location of the building should be taken into account when opting to use natural ventilation because if the environment is polluted, only contaminated air will flow into the house. Other options may be best for these situations.


Mechanical Ventilation 

This type of ventilation relies on machines to having airflow into the house. Fans are installed on the air ducts, walls, and windows to supply air into the room. 

There are three types of mechanical ventilation systems that are commonly used by people in their homes. 

Exhaust-only. These systems work by reducing the pressure inside the building. There is no component that lets outside air into the room. The only way fresh air comes into the building to balance out the pressure is through gaps and leaks. 

Supply-only. This is the opposite of the exhaust-only system. This type only brings air into the home and the only way for it to escape and balance out the pressure is through the gaps and leaks. 

Balanced. This is a combination of both the exhaust and supply-only systems. In this system, the airflow rate of indoor exhaust and outdoor supply is roughly equal.


Hybrid Ventilation

Hybrid Ventilation is the term most commonly used to describe schemes where the ventilation is neither entirely natural nor entirely mechanical. This is the preferred system for most commercial buildings since it does not require as much energy as purely mechanical systems. 


Spot Ventilation

Spot ventilation was created to improve the performance of both natural and mechanical ventilation systems. To put it another way, it's better to call it a support system. 

This entails the use of local exhaust fans, similar to those found in bathrooms and kitchens. It eliminates moisture and indoor air pollution at their source, increasing the utility of the space.


Task-Ambient Conditioning

One of the various types of ventilation is Task Ambient Conditioning (TAC). Individuals determine the appropriate temperature and level of comfort. While some people moan about being too hot, others may gripe about being too chilly. 

Traditional ventilation systems are unable to accommodate one's preferences. This system will be able to cater to the specific needs of an individual or a household. 


Benefits of Proper Ventilation

Health benefits

Air quality is assured when it comes to having proper ventilation in your home. You and your family can reap the benefits through not having allergies, asthma, sinusitis, and rashes. 


Controls Impurities

As the earth gets more and more polluted, people have resorted to wearing masks in densely populated areas. Proper ventilation can help control the impurities that flow into your home. It will also help control odors and moisture. 


Stops Condensation

Over the years, condensation will surely build up if left unchecked. It can lead to mold and rot on the surfaces of your home which in turn, will lead to health hazards for your household. A ventilation system will help mitigate the risk of mold and condensation. 


Regulate Temperature

During the summer times, the house may get too hot and stuffy. A well-ventilated home will ensure the comfortability of those dwelling within it because it will allow the flow of air throughout the house. 


Less Energy Consumption

The installation of a proper ventilation system in a home will reduce energy consumption costs by at least 20% annually. Energy recovery ventilators work like heat pumps. While they remove stale air, they transfer heat out of your home in summer and into your it in winter. 

That way, you can get fresh air without wasting energy or raising your utility bills. A ventilation system can also lower your home’s humidity, reducing your reliance on your air conditioner and extending its lifespan.
