The Index is a 328 m (1,076 ft) 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 tower is oriented exactly along the east–west axis so that the eastern and western concrete cores shelter the floors from the harsh, desert sun and the climatic effects of the area. The concrete cores shelter the building from the low angle, highly penetrating morning and evening sun leaving only the south facade exposed to the high angle, low penetrating midday sun. The south-facing facade utilizes extensive sun shades to lower solar gain.
