What a Commercial Building Without Ventilation Would Look Like?

Posted by admin

Ventilation is one of the most important parts of any commercial building. It controls the way that air flows through the site. A simple thought experiment will allow us to see how important ventilation is. Let’s imagine what would happen if a commercial building was built without adequate ventilation. Here are some of the things you could expect.

Health Problems

One of the most important roles of the ventilation system is to remove filter pollutants out of the air. For example, it ensures that things like smoke, off-gassing chemicals, carbon monoxide, and VOCs are removed from the building. This ensures that the air will be safe to breathe.

However, our imaginary building doesn’t have ventilation. As a result, the people inside will quickly start to develop some serious health problems. One of the most common problems would be the build-up of mould. With the spores not being removed and the moisture allowed to build up, the fungus will easily become established. From there, the increase in mould spores in the air can cause serious breathing problems, especially for those with asthma.

It would lead to a range of other serious health conditions as well. For example, people would experience hay fever symptoms more intensely. They might also start to get fever and muscle aches. This is known as sick building syndrome. The more time people spend inside the building, the worse these symptoms will become.

Lingering Odours

Ventilation is also key to removing unpleasant odours from the building. Without this, they will be allowed to linger. Often, things like mould growth will produce a bad smell.

Higher Electricity Costs

Another problem that will plague the building is higher electricity costs. A good ventilation system will help regulate temperatures. It will keep the building warm in the winter and cool in the summer. However, without this, the occupants will need to rely on things like heaters and fans to create a comfortable environment. This will rapidly increase the electricity bill.

Lower Workplace Productivity

The environment is strongly linked to how productive someone is at work. If workers are placed into a building that is making them sick, they can’t be expected to perform at their best. Plus, a good ventilation system will provide a steady supply of fresh air. This will help workers think clearly.

Structural Damage

Another issue that the owner of the building will need to contend with is the structural damage that lack of ventilation can create. As we mentioned earlier, poor ventilation will create the ideal environment for black mould to flourish. This will slowly break down wallpaper and wood. The longer the mould has been established, the worse it will become, and the harder it will be to remove.


As you can imagine, living in an environment would be a nightmare. If the occupants of our hypothetical building stayed there long enough, there is a chance that the unhealthy environment could do enough damage to their lungs to kill them. The good news is that this doesn’t have to happen to you. Our commercial dehumidifiers will allow you to suck out moisture, ensuring that mould doesn’t form in your buildings.
