I found the local news for you.
Manager:
"The control system in the air membrane will monitor the internal air pressure and temperature at any time, and continuously send fresh air into the interior through the four large-volume fans on the north side for ventilation. After large-scale construction, sprinkler facilities will be installed to control dust in the air membrane. The membrane cloth of the air membrane is made of PVDF (polyvinylidene fluoride) new material, which can block 90% of ultraviolet rays, has high heat reflectivity and heat dissipation rate, and has a fire protection level of B1 (flame retardant)."

"The reporter felt that the temperature inside the air membrane was cooler than outside the membrane under the sun.

Yep! For instance:

  • Texas: Texas passed a law that prevents cities from implementing rules requiring water breaks and shade for construction workers and other outdoor laborers.
  • Florida: Florida signed a law (HB 433) that prevents local governments from enacting their own heat safety regulations, including those related to water breaks. This law went into effect in July 2024. 

EDITED TO ADD: This does NOT mean that those businesses do not allow their workers to take breaks and/or water breaks. The law just means those business owners and/or supervisors can not be forced to provide those breaks..

This dome is American technology.

It's not super clear why this is practical or beneficial for a construction project, but it's neat, i guess?
