To optimize the efficiency and energy-generating capacity of the turbines in this unusual context, we had to perform testing and modeling to gain deeper insight into a number of factors. Ventilation system – Air drawn into the building through its four main inlets is also rerouted into the structure’s ventilation system. A truly collaborative culture of learning. We also used both wind tunnel testing and computational fluid dynamics (CFD) modeling to understand how wind would flow around and through the building. Time limit is exhausted. This is achieved first and foremost through its 309-metre (1,014-foot)-high sculpted faces, which redirect wind to four openings at its mechanical floors. One of the tower’s most innovative features is the integration of wind energy generation into the design of the building itself. Pearl River isn't the first tower to sport electricity-generating wind turbines. The tower takes the northern and southern winds to produce the necessary electricity. They are placed on mechanical floors, which have no windows and are exposed directly to the wind. The idea behind it is that energy produced by on site renewable energy sources is equal to the amount of energy consumed by the building.  =  This trapped heat therefore rises through the skin’s cavity to heat exchangers where it is absorbed and stored for reuse in both energy generation and heating processes. if ( notice ) }, Jump to navigation Jump to search. March 2010 view of the tower under construction seen from Brixton. This is due to the turbines being specifically designed to work across a variety of wind speeds, ranging from small flows moving at around eight kilometres (five miles) per hour, right up to intense 225-kilometre (140-mile)-per-hour surges. ); Where Is Pearl River Tower And How It Work.
