Since my initial conceptualising phase, I have further explored the design elements into my design parameter, overarching theme and biomimicry process. The sketches below founded my ideas so I will explain them first.
The idea of a layered system led my investigation into filters; light and lens filters in cameras, environmental filters for pollution and systems of ventilation which also act as a filter. The above sketch illustrates the idea of an interactive facade for the building which acts as a shading device, filtering sunlight, an environmental filter for air pollution, and a wind filter preventing cold drafts. It is screening device which, placed correctly on the site, allows leafy vegetation to manifest. Drawing inspiration from the idea of a tree acting as a habitat and proving shelter, the screening device links layering with a biomimetic process to green the perception of the HSW site.
The idea of a ventricle filter in section was derived from a leaf which harnesses ventricles for even distribution of nutrients and translated into a ventilation system. The airflow is restrictive allowing for a stable indoor climate. The design is also ducted in a similar way to a termite mound to regulate internal temperature. The cooler air is taken in the lower part of the building where there is usually less ventilation and higher pedestrian flow and the air moves up the structure escaping as warmer air out the top.
The final sketch is a preliminary stylisation of the layered form of the design. It illustrates the different screening devices acting together as one synthesised process.
The final design conforms to these main elements:
Design Parameter (Key Concept) - Filtering the site through human perception.
Biomimicry Process - A layered system of environmental filter.
