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.

German backpacker Carolina Wilga lost hope of rescue after 11 nights in the Australian bush, and only made it out by "sheer luck", police said Saturday.

The 26-year-old walked "confused and disoriented" 24 kilometers (15 miles) away from her van after it got stuck in remote bushland in Western Australia, AFP reported.

As police searched for her by air, the backpacker's ordeal ended Friday when she managed to flag down a woman driving by who took her to police.

"She is still in disbelief that she was able to survive. In her mind, she had convinced herself that she was not going to be located," said Jessica Securo, acting inspector for the Western Australia police.

The rescue was down to "sheer luck".

"I actually spoke to Carolina this morning, so she confirmed that she was very confused and disorientated," Securo told a news conference.

"She basically looked at the direction of the sun and tried to head west, thinking that that would be her best bet of coming across someone or a road."

Wilga had been last seen on June 29 arriving in the van at a general store in the small agricultural community of Beacon, northeast of Perth.

Police found the van on Thursday, abandoned after getting stuck in dense bushland north of Beacon, with plastic orange traction tracks placed beneath the rear wheels.

"It appears that she has somewhat lost control of the vehicle, and then it's become mechanically unsound, and bogged," Securo said.

- 'Overwhelmed' -

She stayed with the van for one day before leaving the vehicle through "panic", hoping to find help.

Wilga was found "exhausted, dehydrated and hungry", suffering from cuts and bruises, but "overwhelmed" to have found someone to help her.

"She had minimal food and minimal water. From speaking to her, she has said she could have planned better."

The terrain "can be quite dangerous", Securo added.

Wilga remained in a Perth hospital and was not expected to be released on Saturday, still needing "emotional support" and treatment for some injuries.

"She's had a good night's sleep. She's had a shower. We've got her some food, which was a massive relief for her. So she's just taking it one day at a time at the moment."

The backpacker is now in "frequent communication" with her family who are relieved and thankful the Western Australian community came together to "throw every resource at locating their daughter", Securo said.

The family had no plans at this stage to travel to Australia.

Police say Wilga had spent two years backpacking around the country, and was working at mine sites in Western Australia while staying mostly at hostels.

"Carolina has told me that she loves Australia. She still has so much travel to do here. She hasn't made it over to the east coast yet, so that's still on her bucket list."
