The General Authority for the Care of the Grand Mosque and the Prophet's Mosque in Saudi Arabia employs sophisticated technology to regulate temperatures within the Grand Mosque in Makkah throughout the year, ensuring a comfortable and healthy environment for worshippers regardless of the scorching summer heat or cool winter temperatures.
The internal temperature is meticulously adjusted based on external conditions, targeting a comfortable range between 20 and 24 degrees Celsius. During the summer months, all air handling units (AHUs) operate at peak efficiency to maintain this ideal range. Conversely, winter sees a significant reduction in AHU usage due to the naturally cooler climate.
Fresh air is drawn from the Grand Mosque's rooftop and undergoes a multi-stage purification process. High-performance filters effectively eliminate dust particles and other microscopic contaminants. Additionally, ultraviolet sterilization effectively combats bacteria and germs, which guarantees clean and healthy air circulation throughout the prayer halls.
The General Administration for Operation and Maintenance at the authority plays a crucial role. Teams of highly skilled Saudi engineers and technicians continuously monitor temperature regulation, maintain humidity levels, and ensure the operation of all systems.
Technicians manage airflow throughout the Grand Mosque, adapting to fluctuating visitor numbers and density, ensuring optimal thermal comfort while maintaining energy efficiency. Maintenance procedures also adhere to strict technical guidelines and safety protocols, guaranteeing the well-being of all visitors.

Crews Rescue 30 People Trapped Upside Down High on Amusement Park Ride

Emergency crews in Oregon rescued around 30 people Friday after they were stuck for about half an hour dangling upside down high on a ride at a century-old amusement park.

Portland Fire and Rescue said on the social platform X that firefighters worked with engineers at Oaks Park to manually lower the ride, but crews had been preparing to conduct a high-angle ropes rescue if necessary. All riders were being evacuated and medically evaluated, and there were no reports of injuries.

One rider with a pre-existing medical condition was taken to a hospital for further evaluation as a precaution, Oaks Amusement Park said in a statement posted on social media. Medics released all other passengers.

The ride, called AtmosFEAR, operates like a pendulum, with the capacity to swing riders completely upside down.

Chris Ryan and his wife, from nearby Gresham, were at the park for his birthday. He told The Associated Press in a Facebook message that they had just been planning to ride AtmosFEAR when they saw it was stuck and heard people saying, “Oh my God, they are upside down.”

They decided to walk away because of "how scary the situation was,” he said. They eventually got on the Ferris wheel and heard a loudspeaker announcement that the park was closed and that people should evacuate.

When the ride stopped, park staff immediately called 911 and emergency responders arrived about 25 minutes later, the park statement said. Park maintenance workers were able to return the ride to its unloading position minutes after first responders arrived.

Portland Fire said about 30 people were on board. The amusement park statement said there were 28 riders.

The ride has been in operation since 2021 and has not had any prior incidents, the park said. It will remain closed until further notice. The park said it would work with the ride's manufacturer and state inspectors to determine the cause of the stoppage.

“We wish to express our deepest appreciation to the first responders and our staff for taking prompt action, leading to a positive outcome today, and to the rest of the park guests who swiftly followed directions to vacate the park to make way for the emergency responders to attend to the situation,” it said.

Oaks Park first opened in 1905. Its website says it offers a “uniquely Portland blend of modern thrills and turn-of-the-century charm on a midway that has delighted generations of Northwesterners.”
