The Index Tower is a 328 m tall, 80-storey skyscraper in Dubai, United Arab Emirates. Of the 80 floors, the first four floors are service floors, 5th–29th are to be offices and 31st–77th are residential use, 73rd and 75th floors are duplex penthouses and 77th to 80th floor are triplex penthouses.
The Index is one of the first towers in the region to intelligently embrace its climatic surrounding environment within its fundamental design principles. The tower's environmental strategy significantly lowers the requirement for air conditioning within the building and therefore substantially reduces the energy costs for its tenants. During the height of the summer, without air conditioning, the tower's internal temperatures will not surpass 28 degrees Celsius
