Makkah | BETH – Feb 21, 2026

Saudi Arabia’s General Authority for the Affairs of the Grand Mosque and the Prophet’s Mosque continues to deploy advanced global operational technologies to ensure a safe and comfortable environment across the Two Holy Mosques and their courtyards, through integrated systems for cooling, crowd flow management, smart lighting, and preventive maintenance operating around the clock.

At the Grand Mosque, one of the world’s largest cooling systems operates with a total capacity of 155,000 tons, maintaining indoor temperatures between 22–24°C through chilled-water networks monitored by 77 temperature sensors and high-efficiency air purification systems reaching 95% filtration efficiency.

In Madinah, a major central cooling plant west of the Prophet’s Mosque powers six cooling units supported by seven main pumps, covering thousands of columns and air-handling units under centralized monitoring.

Crowd movement is facilitated by extensive vertical mobility systems, while smart LED lighting managed through a Building Management System (BMS) enhances energy efficiency and visual comfort.

This operational shift reflects a move toward data-driven smart management at the Two Holy Mosques—enhancing resilience, sustainability, and worshippers’ comfort, particularly during peak seasons, where technology becomes integral to a safer and more serene spiritual experience.
