Best way to ventilate a metal building

Best way to ventilate a metal building

Metal Building Ventilation: Overview

The terms metal building and steel buildings are often used interchangeably. Some of the common issues with a metal building in the USA are condensation development, wrong insulation method, rusting or corrosion, entry of insects, and snowfall in front.

Some brutal weather conditions have been recorded in Florida, California, and Minnesota. A metal building is constructed using non-combustible material such as steel. Only top-notch steel buildings can make living in such states bearable. States with the highest temperatures can adopt an insulation plan that can prevent hot air flow into the interior space.

A ventilation system is meant for temperature regulation and can also improve the quality of air inside. Natural ventilation systems are energy-saving, and with active ventilation systems, you can manipulate the temperature as and when required. Eaves with holes can enhance cross ventilation.

We have answers to all your queries related to the steel building ventilation system. Our diverse clientele includes thousands of companies, from metal agriculture buildings to factories and government agencies.

The Appropriate Vents for Your Metal Building’s Ventilation System

Natural Ventilation

Natural ventilation systems reduce energy consumption as they employ natural forces to maintain good airflow. Just like how it doesn’t require any operating costs, natural ventilation doesn’t demand your time or effort to maintain it.

Cool air replaces warmer air during summers, and airflow is constantly regulated for adequate ventilation and improved air quality for the benefit of the residents. Humid air gets replaced by fresh air through natural means, thereby reducing the need for intervention when the temperature falls.

Apart from preserving indoor air quality standards, natural ventilation doesn’t hurt the environment with carbon emissions.

Components

Windows

Hot and less dense warm air rises upwards towards the roof peak, and this results in a vacuum sucking air out of the building. The space left behind by the excess heat is immediately filled by fresh air through the lower-level windows.

Louvres

Developed by a framed set of metal panels, louvers are designed to rely on prevailing winds to improve a building’s air circulation. These can also resist rain, loud noise, and harsh winds.

Louvres

Framed Openings

These often feature a set of doors that can be operated at will. Framed openings also rely on prevailing winds to maintain temperatures that are close to the ambient temperature outside.

Turbine Vents

turbine vents

Also called wind turbines, turbine vents work with wind energy and let air escape through the roof.

Ridge vents

Ridge Vents

Ridge vents mounted in the high and low-pressure ends facilitate cross ventilation. These also provide passive airflow.

Other Alternative Ventilation Systems Available

Alternatively, instead of opting for a natural ventilation system, you can go for a powered ventilation system. The three basic types of powered ventilation are as follows.

  • Powered supply and natural exhaust

Motorized supply fans, placed 8 or 10 feet above the floor, are designed to divert wind flow back to the lower levels.

  • Natural supply and powered exhaust

Mounted on a building’s roof, mechanical exhaust fans direct airborne fumes and other pollutants out of the building.

  • Powered supply and powered exhaust

Motorized supply and exhaust fans, despite whatever the building size might be, can create an effective method of airflow generation and conduct it towards the center of the building.

Components

Supply/Exhaust Fans

Supply/Exhaust Fans

Supply fans pull outside air into the building, and this creates positive pressure. This would cause other corrosive airborne fumes to leak through the air vents. An exhaust fan does the exact opposite. It creates negative pressure in relatively arid environments and draws fresh air through vents and other openings.

Dampers

Dampers

Damper plates regulate air flow in air-handling equipment such as central air conditioning systems. These can also apply climate control and room-by-room temperature.

HVAC Systems

HVAC Systems

HVAC Systems include heat pumps, furnaces, air conditioners, and thermostats that can heat and cool a building.

The best ways to ventilate a metal building

Ventilation systems pave the way for air circulation, which would aerate the interiors through a ridge vent or turbine vents. When pure air eases its way in, as per the laws of thermal convection, warmer air will rise toward the roof and leak through ridge vents or an exhaust fan.

For every 150 square feet of roof, you must have a 1 square foot vent opening. Ventilation can be generally categorized into two types: passive (unpowered) and mechanical (powered). Passive ventilation systems include ridge vents and unpowered louvers. These are popular owing to their energy efficiency, zilch operating costs, and pocket-friendly initial costs. But in highly humid industrial buildings and livestock barns, mechanical ventilation such as a supply fan or an exhaust fan may be the best option for better air circulation.

For small buildings located in dry areas, a ridge vent or a louver might be sufficient. However, buildings that serve industrial purposes and house livestock would require elaborate powered ventilation.

The Importance of Proper Ventilation in Metal Buildings

  • Preventing Condensation in Metal Buildings

Condensation on metal can result in mold growth, insect infestation, lower insulation thermal performance, and corrosion. For instance, when unventilated humid air enters the premises, it creates an uncomfortable environment in warm areas, causing the metal to deteriorate.

  • Regulating Temperature in Metal Buildings

Temperatures must be regulated in a metal building at all times so that the interiors are cool, making it comfortable for the residents during summer. Otherwise, it leads to excessive expansion and contraction of the metal, which can ultimately affect the fastener’s integrity.

  • Preserving Air Quality Inside a Metal Building

Adequate ventilation ensures the removal of volatile organic compounds and other air pollutants that are detrimental to the health of the animals in livestock barns and workers in industrial buildings or factories.

What Happens to Metal Buildings with Improper Ventilation?

Termites and rot might not pose a serious risk to steel buildings, but excessive moisture can. Damp steel building insulation can promote mildew growth, which fills the building’s interior with a musty smell, and this potentially contributes to asthma or allergy problems. Wet insulation, which is in contact with metal surfaces, can bring about corrosion. This can gradually affect the panels and fasteners as well, which may begin to develop trust, ultimately leading to premature failure of the building materials. An effective way to tackle all your problems related to steel buildings is to get in touch with a professional who can guide you through the installation of a metal building.

Conclusion

Proper ventilation ensures the longevity of steel buildings. Natural means of ventilation are perfect for those steel buildings in areas with prevailing wind flow and thermal buoyancy. Vents mounted on the high and low-pressure ends of steel buildings can cause good airflow. Air vents that promote cross-ventilation are also good choices. Be it passive or mechanical; ventilation is important not just for your building but also for the well-being of its occupants.
