Looking into future development trends and issues related to high density within the city, the project explores architectural solutions that focus on dealing with air pollution and the lack of sustainable energy.  The proposal is a design for a sustainable skyscraper cluster that has integrated vertical wind-turbine technologies and parametric systems inspired from the “dandelion”.  The building form, components and structure incorporates many techniques that maximize wind reception efficiency, performing like a mega-scale air-purification system for London.

The “Green Filter”.

Aerodynamic form: dictated by pflow simulations on digital site models using maxscript coupled with wind map data.

Natural air purification: The spiraling structure consists of many occupied “pods” which house the various functions, residents and “vertical sprawl” green spaces; the wind is promoted up through strategic openings and through these.

Artificial: The external surface of the pods have titanium dioxide (TX active) integrated; attracting impurities in the air, and after a natural and safe chemical reaction, self cleans through natural pass of rain.

Sustainability: Each tower utilizes a parametric skin of vertical wind-turbine arrays; these run more silently (ideal for urban use), and are capable of receiving wind from 360 degrees. These turbines help generate clean energy for the cluster.

An early conceptual model illustrating the parametric skin of the outer structure, made up of vertical wind turbine module arrays.
