Pneumatic structures in architecture are designs that utilize air pressure to maintain their shape and stability, often incorporating lightweight materials like fabrics or membranes. These structures can be rapidly deployed, offering flexibility and adaptability for various uses, such as temporary installations or shelters. They are known for their efficiency, energy-saving potential, and unique aesthetic appeal. Common examples include inflatable buildings, air-supported roofs, and tensile fabric structures.
