What happens when Ventilation is not properly planned?

 While constructing a house, it is very important to keep in mind the indoor environmental quality.

With increased awareness about the indoor environment, people are realizing the importance of maintaining a proper indoor environment.

Indoor air quality is one of the most important aspects of the indoor environment.

In the indoor air quality itself, ventilation is a very important parameter.

 In this article, we are going to discuss the importance of ventilation and also learn what happens when ventilation is not properly planned.

The role of ventilation in a building is to more the outdoor air inside and distribute it in the room.

Ventilation is necessary to provide healthy air inside a building.

It helps in diluting the pollutants originating in the building and also removing them. The important elements that one should make note of when it comes to ventilation are the ventilation rate, airflow direction, and airflow pattern.

The different methods by which a building could be ventilated are natural ventilation, mechanical ventilation, and hybrid ventilation.

 So what happens when the ventilation is not properly planned.

 ·         The air indoors is more polluted than the outside air generally.

Studies also reveal that people spend 90% of their time indoors.

So in case, the ventilation system is not good, the air in the room will be polluted and thus prove detrimental to the health of your family and you.

Therefore ensure that the ventilation system in your home is proper to enjoy the benefits of clean air, free of pollutants and bacteria, and moisture.

 ·         If your ventilation system is not good you will not have good airflow in your home.

        It would be a struggle to get fresh air.

       An inefficient system would mean higher energy bills.

       The benefits aren’t limited to purely being economical and health-related either. Having proper airflow would allow your home to be free of any unwanted smells such as from cooking or from pets etc.


·         In case of improper ventilation in your house, be prepared to suffer from the problem of condensation which could lead to mold.

Damp conditions can result in allergic reactions as well breathing problems.

With proper ventilation in place, you wouldn't have to worry about those things.


·         A badly ventilated room will get hot and stuffy when a lot of people are in it. Whereas a well-ventilated room will be comfortable for everyone to inhabit.

The difference could be felt.

It might be even more pronounced for people who have respiratory problems.


·         Improper ventilation can be a serious reason behind health issues such as headaches and sinusitis because the inhabitants of the house wouldn’t be exposed to fresh air and would have to deal with pollutants as well.

·         Volatile organic compounds, also known as VOCs are emissions from chemicals and furnishings which are toxic.

Improper ventilation would result in the build-up of VOCs on the house. Therefore, maintaining an adequate ventilation system is very important.

·         Another consequence of improper ventilation is that there could be an issue of back drifting.

It occurs when the pressure inside the home is lower than the pressure outside, in such cases what happens is that the outdoor air is pulled into the home which could be dangerous when gases such as carbon monoxide are pulled back into the house through chimneys or other openings or from diesel generators and become concentrated.


These were some of the consequences of improper ventilation in the house.

We hope that this article might have helped you in realizing the importance of ventilation in your home and that you would know what factors to consider while checking whether the house is well ventilated or not.
