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.

Wildlife rescue teams scoured Australia's east coast on Monday to find and free a distressed humpback whale tangled in a rope.

Aerial footage showed the whale swimming south of Sydney Harbor trailing a rope attached to a floating buoy.

"It makes it more difficult for the whale to dive," said Pip Jacobs from whale rescue group ORRCA.

"It's tiring for the whale, which is already in a state of distress being tangled."

The whale was about eight meters (25 feet) long, Jacobs said, indicating it was still "quite young".

The rope appeared to be tangled around the whale's left pectoral fin, she said.

"The way it is moving is quite erratic," Jacobs told AFP.

"It's moving south which is unusual.

"They should be heading north as part of their migration."

Teams of volunteers and wildlife rescue experts were searching the coastline to pinpoint the whale's location, she said.

But efforts had been hindered by choppy waters and blustery winds.

"If conditions allow and we have eyes on the whale, the best-case scenario is we have a successful disentanglement.

"If they are dragging gear, it hinders their ability to swim freely. The worst-case scenario is the whale can't feed or swim."
