They are increasingly being used in architecture for their many benefits, including: 

  • Reduced material consumption
  • Increased energy efficiency
  • Flexibility in design and construction

Why Pneumatic Structures?

Pneumatic structures have become a popular and innovative building solution in architecture due to their many benefits. As an alternative to traditional building materials, such as steel, concrete, and wood, pneumatic structures are lightweight and air-filled, relying on air pressure to maintain their shape and stability. 

This makes them an eco-friendly and sustainable option that reduces material consumption and increases energy efficiency. 

Types of Pneumatic Structures 

Pneumatic structures are classified into different types, each with its own unique characteristics and applications, such as:

  1. Air-Supported Strcuctures
  2. Tensile Membrane Structures
  3. Pneumatically Stabilized Structures

1. Air-supported Structures

Air-supported structures consist of a single layer of fabric supported by a continuous flow of air. This creates a dome-like structure that is lightweight, yet strong enough to support large crowds of people. Air-supported structures are ideal for use in sports stadiums, exhibition halls, event spaces, and even greenhouses.

Air-supported structures can be designed to optimize energy efficiency and reduce environmental impact. They can also be used as temporary structures for events, which can be inflated and deflated as needed.

This structure is the largest ETFE-clad structure in the world with over 100,000 m² of ETFE pillows. Made of a steel space frame, the pillows in between allow more natural light and heat to penetrate inside in comparison to regular glass. This in turn reduces energy usage of the building.

2. Tensile Membrane Structures

Tensile membrane structures are made up of a series of cables that support a flexible fabric membrane. This creates a lightweight, yet durable structure that can be easily shaped into a variety of forms. Tensile membrane structures are ideal for use in airports, museums, outdoor amphitheaters, and even parking garages.

Tensile membrane structures can be designed to optimize energy efficiency and reduce environmental impact. They can also be used as a permanent or temporary structure, depending on the application.

The Millennium dome is the largest of its kind in the world. The structure has a huge white dome in the center with 12 protruding 100 m high support towers depicting 12 months and 12 hours of the clock. It was built in such a way that the roof structure weighs less than the air inside it.

The canopy-like dome structure is 52 metres in height. It is made of durable and weather-resistant PTFE-coated glass fibre fabric panels, since it is exposed to the London climate.

3. Pneumatically Stabilized Structures

Pneumatically stabilized structures are characterized by an inflatable core that provides structural stability and support. This creates a lightweight, yet strong structure that is ideal for use in disaster relief shelters, temporary housing, and military barracks.

Pneumatically stabilized structures can be designed to optimize energy efficiency and reduce environmental impact. They can also be used as a permanent or temporary structure, depending on the application. 

US Embassy, London

This embassy building resembles a cube sitting on top of two-storey colonnades. The facade allows proper daylighting while also blocking out harsh sunlight from east, west and south. The ETFE foils include thin photovoltaic film that intercepts unwanted solar gain in certain angles.

Benefits of Pneumatic Structures 

1. Increased Energy Efficiency

Pneumatic structures are highly energy efficient because they require less energy to regulate the temperature inside than traditional buildings. This is due to the air inside the structure acting as a natural insulator, reducing the need for additional heating and cooling.

2. Reduced Material Consumption

Compared to traditional building materials, pneumatic structures require less material to construct, making them a more eco-friendly option. They are also lighter than traditional buildings, reducing the amount of energy required to transport materials to the construction site.

3. Flexibility in Design and Construction

Pneumatic structures offer high levels of flexibility in design and construction. They can be easily inflated and deflated, allowing for quick and easy transportation and assembly. This makes them an ideal choice for both temporary structures, such as disaster relief shelters, and permanent structures, such as sports stadiums and exhibition halls.

4. Lower Construction time and Cost

Pneumatic structures can also be constructed faster and at a lower cost than traditional buildings. They are also more resistant to natural disasters such as earthquakes, hurricanes, and tornadoes, making them a safer option in certain areas.

It is crucial to explore and innovate with the use of new structures. By doing so, we can create buildings that are not only functional and beautiful, but also environmentally friendly and resilient.
