The 119-level tower will be comprised of 300,000 sm of floor area, including about 200,000 sm of offices, 50,000 sm of luxury apartments and condominiums, a 45,000 sm five-star hotel, and a 5,000 sm, 27-meter-tall private club with spectacular views at the tower’s penthouse level.
The tower features a uniquely streamlined form that combines three key shaping concepts—a tapered body, softly rounded corners and a domed top—to reduce wind resistance and vortex action that builds up around supertall towers. The building’s extremely efficient aerodynamic performance will allow it to minimize the amount of structural material needed for construction.
The tower’s three corners taper upward, culminating in an arched tip above the dome at the top. The corners will be smooth curved glass, contrasting with the more textured curtain wall cladding the body of the tower. Apertures in the curtain wall at regular intervals will assist in venting wind pressure against the tower; the apertures will also house window-washing systems and air intake and exhaust systems on mechanical floors.
Other planned sustainable elements of the project include:
- Energy recovery using an enthalpy wheel integrated into the ventilation system; this captures energy from the building’s exhaust systems and uses it to pre-heat or pre-cool air entering the building.
- A greywater recovery system, which takes waste water from the hotel laundry, sinks and showers and reuses it in the building’s evaporative cooling system.
- A high-efficiency lighting system, which uses low-energy-consuming ballasts and lamps to reduce required power consumption.A daylight-responsive control system, which automatically turns off electric lights when sufficient daylight is available.
- Water-conserving low-flow plumbing fixtures, which reduce the total amount of potable water required as well as the associated pumping energy.
