Wuhan Greenland Center
Wuhan Greenland Center is a 600+ meter tall mixed-use tower featuring office, residential and hotel functions and including club and observation levels, lobbies, and mechanical floors.
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
- 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.
- Energy recovery chiller for preheating of hotel domestic hot water.
- Condensor water economizaer for free cooling during winter months.
- Condensate collection system for use as cooling tower make up.
A uniquely streamlined form combines three key shaping concepts—a tapered body, softly rounded corners and a domed top—to reduce wind resistance and vortex action that affect supertall towers. The building’s extremely efficient aerodynamic performance will allow for reduced structural material (and associated embodied carbon) needed for construction. Apertures in the curtain wall at regular intervals will assist in venting wind pressure against the tower, and will also house air intake and exhaust systems on mechanical floors.
