Design Concept Sketch

Sketch - The serpentine like guesture signifies the winds apprehensive direction in relation to the buildings mass; but not only does it identifies the contour seperating the diffferent programs at different levels, it's purpose is to direct the air flow into the diffferent spaces. At ground level harnesses the air flow from the I-90 Interstate. The mid section (body of the building) has fin like louvers to intake the wind flow from the John Hancock wind tunnel effect along the perimeter of the building into the space and out the shaft dampers along the courtyard side of the building; also to generate the hidden mechanical penthouse space below the rooftop golf range. And at the top tier (known as the Head) is where the serpentine contour ends as the T-off point for the golf range.





The RADAC

Recreational Air Dynamic Atheletic Complex - Sports complex designed to harness the wind loads of its surrounding context in naturally ventilating the building in efforts of sustainabilty and the environment. The wind rose study of the area has exposure to constant wind flow caused by the wind tunnel effect of large buildings (ussually in dense metropolitan areas) and an underpassive vehicular interstate. With the city's plan of filling in the parcel air-rite site, it'll create a underpassing tunnel. Therefor, the building has potential in the innovative creation of adaptive wind driven thermal comfort.

Site Visit

Steady warm summer august day. The air is gradually moving. Began my walk on stanhope street heading towards clarendon. As I wrapped around the building's corner of Flour bakery, a constant harsh wind flow from john hancock tower rushes south. This phenomenon is caused by the wind tunnel effect of large buildings using roads as the corridor of travel at pedestrian level.

The Interstate highway below with the transit railway system causes forced windflow from the velocity of traveling objects (vehicles and trains). The fast moving objects pushes the air creating forceful wind. The interstate under the air-right sites are essentially tunnel driven.

These phenomenon of the wind tunnel effect is an opportunity to harness the winds path in directing Parcel 16 building with a natural ventilated system.

Wind tunnel study of pedestrian level wind environment around tall buildings: Effects of building dimensions, separation and podium

http://www.sciencedirect.com/science/article/pii/S0360132311002575 C.W. Tsang It is well known that high-rise buildings affect the surrounding pedestrian level wind environment. In recent years, awareness and concern has increased about the creation of low wind speed areas around tall buildings which may lead to poor out-door air ventilation. In addition, new building developments are often not restricted to a single building, but comprise a row of buildings, which may have complex plan-forms, and some integrating an extensive podium. This paper aims at providing a fundamental understanding of wind–structure interactions that govern the effects of building dimensions and separations, a row of buildings and podium on the pedestrian level wind environment, for both weak and strong wind conditions, by a series of parametric wind tunnel studies. The study area covered an extensive area which covered up to 400 m downstream of the test buildings. The results show that a single wider building created adverse effects on the natural air ventilation at pedestrian level around the building while a taller building improved the near-field air ventilation conditions. In the studies of building separation effects, the results show an adverse effect on natural air ventilation at pedestrian level when the building separations are less than half the building width. Inclusion of a podium was also found to adversely affect the air movement around buildings.
