Cross�ow and Vortex development studies developed using a wind tunnel
Velocity Magnitudes studies developed using Computational Fluid Dynamics CFD Fluent 6.3
Arabic wind tower DubaiShowing system of pressure systems inducing air movement
The Masdar Headquarters in Masdar City, Abu Dhabi, UAE, will be the world's �rst large-scale, mixed-use, positive-energy building (above). The design consists of eleven glass-enclosed wind cones
CFD software was used to model the building geometry and surrounding wind patterns. Hot winds traveling at high velocities around and over the cone openings create low pressure areas, inducing air�ow out of the cones. The cone’s shape captures cool air moving in the opposite direction.

Paper based triangular component used in previous structural design exploration.These components became a load bearing facade system.This was planar, although there is potential for vertical generation

Component misconnection and limitation of generation
In physical model these can be forced to connect, but if symmetry lines are followed strictly the components will not connect
Component misconnection and limitation of generation
This connection issue can be resolved by using a connecter component in the form of a ‘X’
