Mechanical, Electrical, Plumbing A/C
Seven double-story height mechanical floors, distributed around every 30 stories
The mechanical floors house, the electrical sub-stations, water tanks and pumps, air-handling units, etc.
Electrical demand
The tower's peak electrical demand is 36 mW
Water supply system
The Burj Khalifa's water system supplies an average of 946,000 Liters of water per day, through 100 km pipes, 213 km piping serves the fire emergency system, and 34 km piping serves chilled water for the air conditioning system
Air conditioning System
The air conditioning system draws air from the upper floors where the air is cooler and cleaner than on the ground
The exterior temperature at the top of the building is said to be 6 °C cooler than at its base
At the peak cooling times, Burj Khalifa will require about 10,000 tons of cooling, equivalents to that provided by 13,000 tons of melting ice in one day
Hot, humid climate in Dubai, combined with the building's cooling requirements, creates a huge amount of condensation moisture from the air, which is collected by the tower's cooling condensate collection system in the basement car park, provides about 15 million gallons of supplement water per year
This water is then pumped into the site irrigation system for use on the Burj Khalifa Park
Elevators & Lifts
Burj Khalifa have 57 elevators and 8 escalators
Burj Khalifa's Observatory elevators are double deck cabs with a capacity for 12-14 people per cab
Fire safety and speed of evacuation were prime factors in the design of Burj Khalifa
The building service/fireman's elevators have a capacity of 5,500 kg
