Overview
Abstract
This research looks at the relationship of material and geometric distribution to set a methodology for integrating structural and thermal design. The basis being that today, a separation of concerns is witnessed between these two fields, resulting in excessive facade multi-layering and redundant material use.
The aim is to explore the feedback loop that can be created between a structural system and a thermal scheme in order to develop a deeper understanding of the synergies and clashes between both systems. This is done through investigating a multi-topology design language that capitalizes on an existing structural networks to carry out selective thermal exchanges. The intention here is to tune loading distribution to thermal opportunities on several scales and re-merge the concerns of thermal and structural design. This is done through applying a thermal hollow core wall design to maximize insulation potential in cellular facades that are structurally optimized for various loading.
Multi-scale optimization is carried out to address the architectural implications of the union of both these fields and map out possible integrations. The tested design proposition works with the idea of material removal, to tune the inosculation of flows in a thermal resistance scheme. The aim is to use cellular geometries to increase insulation potential through strategic material removal. Structural optimization +studies are carried out in addition to thermal physical testing to determine performance.
