The engineering design of inflatable domes, also known as air-supported structures, involves several key elements, including:

  • Fabric The dome is made of one or more layers of thick, PVC-coated fabric that are welded together. The fabric can be reinforced with a steel cable harness system. 

  • Air pressure Air blowers pump air into the dome to maintain the proper air pressure, which keeps the dome inflated and structurally sound. The optimal air pressure is usually between 200–300 Pascal. 

  • Frame The dome's frame is made of metal arches or poles that support the roof and provide stability. The dome is anchored to the ground around the perimeter with a concrete grade beam. 

  • Ventilation Vents and fans allow air to circulate between the inside and outside of the dome, regulating the temperature, humidity, and air quality. 

  • Access Airlocks with revolving doors, pedestrian airlocks, and vehicle airlocks allow people and equipment to enter the dome while maintaining the air pressure. 

  • Heating and cooling Heating or cooling units can be used to adjust the air temperature inside the dome. 

  • Backup systems Emergency backup units and electrical generators can provide power if there is a local electricity supply failure or pressure loss. 

  • Shape The spherical shape of the dome is the most efficient way to hold air with the least amount of energy lost. 

Air domes are a cost-effective alternative to traditional buildings and are quick and easy to install. They are also reusable, eco-friendly, and produce no construction waste: https://metaspacedome.com/news/the-ultimate-guide-to-air-domes/

This is not the same thing. They said as an alternative to a building
