Natural Ventilation Systems

Natural air ventilation is using an unpowered means to evacuate hot, stale air and fumes from a space. Utilizing the natural convection properties offered by process heat and providing a natural path of least resistance. By allowing rising hot air to escape, you create a natural ventilation solution.

Additionally, a system of natural replacement air should be provided by adding openings low in the building that aid in the evacuation process by adding cooler intake air down low as the warmer hot air is expelled above.

To operate, the roof or ceiling has an opening through a weatherproof ventilator. Fresh air flows at the floor level. The floor-level intake air can come in through existing openings or can be facilitated through a series of louvers and dampers.

These natural air ventilation systems create a cooler and more comfortable building with no operating costs, energy consumption, or maintenance.

Natural Ventilation Requirements

Many factors play a role in determining the operational requirements for a natural ventilation system.

The main factors considered are:

Equipment for Natural Ventilation

Proper ventilation equipment is necessary in order to implement a natural ventilation system. Several factors are involved, including, but not limited to, structure type, application, and size. These factors play an important role in the equipment required.

Listed below is a list of the more common natural ventilation equipment.

Natural Ventilation Vents

Vents exhaust a substantial amount of warm air. This is done without allowing rain or other precipitation inside the structure. Available in various sizes, natural ventilation vents are able to meet building specifications while adhering to local city and state codes.

Ventilation vents can withstand winds up to 130 MPH. Wind direction and speed do not impact the effectiveness of the natural ventilation vent.

Low-profile vents minimize the effect of wind while reducing weight. They are made of aluminum and steel. They are also waterproof.

Natural ventilation vents can further reduce the need for electricity in a structure by introducing natural light into it. Warm air is exhausted by opening the flaps. When they are closed, they allow light to enter while still protecting the inside from outside elements.

These multi-functioning vents are designed with industrial and commercial applications in mind.

Natural Daylighting Vents

Natural casement ventilators are manufactured with versatility in mind. Can be fitted either horizontally or vertically and designed to meet aesthetic demands while remaining functional.

Industrial Roof Ventilation

Roof ventilation systems significantly enhance the circulation of air within buildings, thereby not only increasing comfort levels by reducing heat and humidity but also improving the longevity of equipment. The promotion of optimal temperature and moisture conditions helps prevent the premature deterioration of machinery and infrastructure due to overheating or corrosion.

In addition, better air quality resulting from efficient ventilation can reduce the risk of harmful airborne contaminants, contributing to a safer and more productive work environment.

That’s why roof ventilation systems are important for both operational efficiency and the preservation of assets, like equipment, in the long run.

Ventilation equipment include large ridge vents, turbine vents, or powered exhaust devices, allowing hot, dirty air to escape and fresh air to enter, typically via wall louvers or intake fans.

 

Natural Casement Ventilator

A natural casement roof ventilator is a great natural solution for day-to-day ventilation as well as smoke control. With high acoustic, thermal, and aerodynamic performance that is suitable for a majority of commercial and industrial applications.

Natural casement ventilators are manufactured with versatility in mind. Can be fitted either horizontally or vertically and is designed to meet aesthetic demands while remaining functional.

Natural Ventilation Louvres

Natural ventilation louvers come in a range of weather protection choices, blade profiles, and design styles that suit the project. They can be factory-built or on-site assembled. Either way, louvers still have the flexibility of custom designs to match complex building architecture.

Turbine Ventilators

Turbine vents are essentially exhaust fans that rotate in the lightest of breezes. Regardless of whether there is wind, turbine ventilators continuously expel warm air. This is due to warm air rising through natural convection, drawing warm air up and out of the turbine. This self-perpetuating cycle is what makes turbine vents valuable for natural ventilation systems.

They are made of light-gauge but durable marine-grade aluminum materials that are made to last and will not rust or seize. Additional turbine configurations include:

Diffusers

Specifically designed diffusers for natural ventilation systems. The aluminum plate-type heat exchangers recover heat from the air. The heat exchangers effectively transfer heat from warm air to cold air with efficiency and high conductivity.

Gravity Roof Vent

Gravity roof vents are also known as roof-mounted gravity relief vents or relief air openings. These rectangular hoods come with a backdraft damper and a bird screen. Silencers for the gravity roof vent are optional.

Industries Using Natural Ventilation

Natural ventilation systems are used in a variety of commercial and industrial applications. These systems are a natural way of improving air quality within buildings. 

Below are just some of the industries that benefit from using natural ventilation systems:

Natural Ventilation in Commercial Buildings

Office buildings and other commercial office spaces account for 76% of electricity consumed in the US (source). The concern with commercial buildings is that it’s necessary to keep occupants comfortable when outside temperatures are not suitable for indoors. That is where a natural hybrid ventilation system comes into play.

Other Industries & Types

Hybrid ventilation is used by some of the largest companies in the world, such as Apple and Google. Hybrid ventilation, or the mix method, combines mechanical ventilation and passive ventilation to ensure indoor temperatures are kept comfortably stable.

Naturally ventilated when there’s wind and a lower temperature outdoors. Conversely, the building is air-conditioned and uses mechanical ventilation for the remainder of the time.

Sensors are strategically placed throughout the commercial building to monitor:

Temperatures do not have to be frigid to reap the benefits of natural ventilation in data centers. That’s why over half of data centers are now choosing natural ventilation to cool their servers (source).

Industries that involve generating power or, in some form, contain equipment that accommodates power generators could benefit from natural ventilation systems.

Some of the common energy-generating areas that would benefit from passive ventilation are:

Overall, dampers play a critical role in pharmaceutical manufacturing facilities, contributing to improved efficiency, safety, and environmental compliance.

As the demand for sports facilities increases (source), attention is drawn to creating an energy-efficient structure while maintaining a healthy environment. That’s why natural ventilation in sports facilities is an ideal choice.

Industrial buildings, such as mills, benefit from natural ventilation systems. The high ceilings allow heat to escape easily. Allowing the hazardous materials to ventilate easily through strategically placed vents.

Fresh air flows freely inside to push odors, dust, and fumes up and out of the mill. This is all done without any additional noise.

Common industrial mills that benefit from natural ventilation are:

Benefits of Natural Ventilation

Manufacturers and companies are seeking a path to reduce the consumption of energy, which has a positive impact on the environment and reduces carbon emissions.

By implementing natural ventilation systems into a structure, an immediate reduction in the amount of energy used can be measured. Natural ventilation reduces a structure’s overall carbon footprint.

The most obvious benefit of natural ventilation systems is their economic benefit. Naturally, companies consider their bottom line. Implementing a natural ventilation solution is a one-time fee with minor upkeep.

Studies show that commercial buildings consume the highest amount of energy. The majority of energy is used for heating, cooling, and ventilating the occupied spaces.

Office equipment, lighting, cooking, and refrigeration all emit heat. The energy consumption required to cool and ventilate a commercial building can be reduced by incorporating a natural ventilation system into the building design.

Many energy companies subsidize green solutions such as natural ventilators. Utility companies in the U.S. have programs that encourage energy-saving infrastructure improvements. This is completed by assisting with purchases or offering rebates. Not only can the energy savings be seen year after year, but little to no money is paid upfront for the equipment.

Depending on the size of the structure, a commercial or natural ventilation system could save enough electricity to power 2,000,000 fluorescent bulbs for a year. That’s enough to power 10,000 offices.
