When designing a building, a key consideration every engineer and architect should consider is the promotion of airflow within the structure. Ample airflow is vital for several reasons, with one primary one being the comfort and safety of equipment and people housed within the structure.
The good news is that there are several ventilation options that can keep a building’s interior safe, productive, and clean. Mechanical ventillation systems, typically powered through electricity, are considered highly effective in drawing fresh air in and exhausting stuffy and old air out.
But, as it can be derived in their name, these ventilation systems tend to be powered by gas or electricity—which isn’t ideal for companies that want to integrate sustainability and environmental friendliness in their operations.
Fortunately, natural ventilation systems exist and are just as effective in promoting the natural and cylical flow of air within building premises. There are several versions that operate in silghtly different ways, but they all help promote a building’s sustainability and airflow operations without requiring extra electricity costs.
If you’re keen on integrating natural ventilation systems in your building, or are curious to know about its effectiveness, then you’re in the right place. This article will delve into how you can design healthy and green ventilation systems within your building.
Let’s get started!
What Are Natural Ventilation Systems?
Natural ventilation systems are a category of ventilation systems that operate passively without the need for electrical input. These types of vents harness physics to circulate fresh air throughout the building interior without relying on mechanical fans or exhaust pipes.
Scientifically speaking, vents like natural ventilation solutions by Airocle use buoyancy and wind pressure to promote indoor air circulation. Hot air tends to rise while cool air stays low, and as this is the case, natural vents tend to be situated at the top of the building structure—usually along the roofline, but this can vary depending on the building’s individual design.
Functionally speaking, natural vents also help keep the atmoshpere inside a building from getting too stuffy and hot. When there’s nowhere for air to escape, heated air particles can accumulate along the top of the building. This can cause a temperature imbalance. It can also cause health hazards as dust, bacteria, and particulate matter have nowhere to readily exit from the building, with it ending up in the air people breathe inside the premises, which can be a health hazard, to say the least.
Fortunately, natural ventilation systems effectively solve this issue, making a building’s interior safe and easy to breathe in. When indoor air is of good quality, it can do a whole lot of good in helping businesses realise sustainability and operational objectives in more ways than one.
What are The Different Types of Natural Air Vents?
There are several different types of natural and passive air vent systems that companies can use and integrate into their building operations.
Here are a couple of these air vent structures that are popularly used by buildings that feature air ventilation systems:
- Louvres: These air vents have slatted openings that allow air to pass through while preventing rain and fallen debris from entering through the roofline. This type is often used in industrial building designs.
- Trickle vents: Small, adjustable vent systems that allow continuous and controlled airflow. Often installed near window frames and walls to maintain airflow without utilising a big and exposed gap to minimise security risks.
- Box vents: Also known as a turtle vent, this vent is a small box-shaped structure mounted on the roof surface that acts as a natural exit point for air. It can be placed in numbers along any part of the roof.
- Gable vents: This vent type is situated in the top-middle section of the vertical wall between the triangular roof structure and the flooring beneath it. It exhausts air through passive means as the placements work naturally well for air to flow out of.
- Ridge vents: Another vent type that’s effective in promoting airflow, ridge vents are installed along the peak of sloped roofs, helping pull off the principle of air density and cyclical airflow.
As observed, there are various passive ventilation systems that can help keep a house or building’s structure cool and pleasant 24/7. This, in turn, helps keep the interior sustainably comfortable throughout the day and night.
What are the Benefits of Natural Ventilation Structures?
Using a passive ventilation source can do your building a whole lot of good in more ways than one. Here are some benefits of incorporating this ventilation type in your establishment or house.
It Keeps Indoor Air Pleasant Year-Round
One straightforward benefit of natural ventilation is its ability to passively cool an area without needing manual intervention. Passive vent structures naturally support air movement. And when air constantly cycles through properly-positioned vents, this supports an indoor environment that requires around-the-clock cooling.
If there’s a power outage that affects your building, a passive ventilation structure gives building owners a means of removing airflow. This isn’t the case for owners who solely install and rely on mechanical vent systems, as they’ll be out of luck if they require ventilation during times when power is cut off.
It Supports Everyone’s Health
Another perk of passive ventilation is its ability to keep everyone inside the premises healthy for extended periods. When air has nowhere to escape, it can create an indoor environment that’s stuffy and prone to harbouring bacteria and viruses. This can cause people to experience a slew of flu-like and respiratory illnesses with varying levels of severity.
For an operating workforce, such conditions can be problematic as they can wipe out productivity as people constantly have to file sick leave and wait for several days to get better. With a passive vent structure, you can rest assured knowing that infected air particles can be blown out of the premises—giving everyone indoors a better chance of staying healthy and productive.
Diverse Range of Options
Another perk of passive vent systems is the wide array of available options you can consider to install in your building.
As listed above, there are more than a few ways of keeping your indoor building passively cooled and fresh without adding to your electricity bill. And for buildings with unique architectural layouts, this means that you won’t be in shortage when it comes to ways to regulate indoor temperature and humidity.
A few of the most popular passive vent systems, like ridge vents and box vents, are highly effective in cooling environments on their own. And when supported by mechanical, HVAC-powered ventilation systems, then the indoor environment will naturally be equipped to handle all sorts of humidity-causing and temperature-raising environments.
The best way to choose the most effective vent structure for your unique needs is, of course, by consulting a design professional and a vent installation service about it. This way, you can rest easy knowing that your chosen vent option is suitable for handling your exhaust needs for years to come.
4 Supportive Ways to Keep Indoor Space Green and Healthy
Natural ventilation systems are highly capable of bringing down excess humidity and regulating indoor temperatures. But putting them up is not the only way to promote a green and healthy environment.
Here are some other ways you can support an indoor space green and healthy for all your inhabitants:
- Install mechanical vents: Mechanical vents have a higher capcaity of sucking air in and out of the premises.
- Use cross ventilation: Putting two ventilation systems opposite of each other can heighten the rate in which air cycles through the premises.
- Put up plants and air purifiers: Plants and air purifiers can keep the indoors feeling fresh and breezy.
- Install soffit vents in lower floors: Soffit vents promote the intake of air in the first floors of the building, making it easier for old air to flow out from the top.
We hope that we’ve helped given you enough ways to create a green and clean environment in your home or commercial building. All the best in using these vent systems to promote a safe and pleasant building!
