Bio-Scaffold

Project details

Programme
Year 1

Urban greening is an effective strategy to pacify the effects of climate change. It results in reduced cooling costs and carbon sequestration from the atmosphere and can be applied to diverse climate situations. However, urban spaces are expensive, and many greening strategies like green walls are resource intensive. Hence, there is a need to develop sustainable, less resource and energy-intensive solutions for urban greening in the face of climate catastrophe. Bio-receptivity is an emerging sustainable concept which can serve as an alternative to current resource-intensive urban greening strategies.


This project emerged from the idea of incorporating nature into the architecture of contemporary building structures to tackle the impending climate catastrophe. In the contemporary context, architectural façade systems exhibit the presence of well-defined limits in how they interact and negotiate with the natural environment. They act as a shield from the external environment. This is in stark contrast to nature, where there are no boundaries but only intricate relationships and interactions between organisms and their ecosystems.

01

Material Explorations

Bioreceptivity

The water retention capacity of the material is dependent on the porosity and surface roughness of the material and is a key factor that affects bioreceptivity.

Sugarcane Bagasse

Sugarcane bagasse is an agro-industrial residue and contains 60 to 80% carbohydrates.

Internal Porosity of Different Samples

The interiors of the samples were picturised and examined in ImageJ software. The percentage of porosity is calculated using the ratio of the overall pore area and the actual area.

Surface Roughness of Different Samples

The surfaces of the samples were examined using ImageJ software. The percentage of porosity is calculated using the ratio of the overall pore area and the actual area.

Bio Receptivity Tests

Bio Receptivity Tests

Capillary action test to determine the water absorption capacity of the samples.

Design Development

Geometry Development: Data-Driven Approach

Geometry Development: Data-Driven Approach

The massing is derived from the vector fields generated in correlation with incident solar radiation within the bounding box of the site.

Velocity Vector Field

A velocity vector field showing various densities of fog volume, from which point trails are developed. The density of the vector field is dependent on massing in and around the site. The direction of vector field volume will affect the point trails.

Porous Configurations

Porous configurations are of relevance in natural science and have been observed in biological membranes and bone structure.

Transitional Geometries

Transitional Geometries

The scaffold, with interconnected voids, is modularised to achieve transitional geometries without losing the gradient and porosity.

03

Fabrication

Hand Extrusion Tests

Hand extrusion tests, manipulating the material by hand.

Robotic Extrusion Tests

Robotic extrusion tests, using different material compositions.

3D Printed Sample

Material Gradient

A combination of materials in a single brick is proposed. The core structure of a module can be a mixture, which is sturdy and hydrophobic, and the outer layer of the module can be a porous and hydrophilic material.
