Best tall building tower of greenery.

CHICAGO -- One Central Park in Sydney has been selected as the Best Tall Building of 2014 by the Council on Tall Buildings and Urban Habitats (CTBUH) in a yearlong process across 88 entries.

The 2,750,179 [ft.sup.2] (255 500 [m.sup.2]) residential high-rise features two unusual technologies for tall buildings-hydroponics and heliostats-to grow plants around the periphery of the building at all levels. The shading saves cooling energy, while the heliostat directs sunlight for heating and lighting into or away from the building and the adjoining park when it is most needed.

The development's economies of scale allow a 30 MW central thermal plant, a 2 MW trigeneration system and a 1 ML/day (264,172 gallon/day) black-water treatment plant.

The 34-story project was completed on schedule and on budget at $4,743 U.S./[m.sup.2] ($440/[ft.sup.2]). Ninety percent of the initial apartments sold within three months.
