The Faculty of Architecture and Design Building for Victoria University is undertaking a complete renovation of the ground floors.
Key to this revamp was the addition of a new accessible-friendly entrance along the front facade of the building opening the school to up the adjacent Cobblestone Park.
The faculty offices have been relocated to face outwards over the ramp towards the park. This allows the offices access to natural light however a privacy issue is created. While a pedestrian is traversing the ramp, their eye-level could be positioned at the under-desk region of the offices located above.
To address this issue, perforated aluminium screens with varying densities of porosity are to line the inside of the curtain wall. These screens are on rollers to allow an office to opened up if desired. The screens are to be created by folded aluminium which gives the sheet material enough strength to be sliding partitions.
My role in the project was to design a parametric screen providing a porosity logic that adapts at three levels to address several pragmatic issues.
The lower portion of the screen is set at a lower cut-out density obstruct vision of pedestrians while maintaining a continuity of the underlying pattern. Above the desk the screen becomes more porous to let light in, and to see out.
A further adjustment is made at the upper portion of the screen to control the solar gain by again reducing the density of cut-outs.
It was scripted in Grasshopper which produces both a 3D model as well as a DXF cutting pattern directly for the CNC.
