Summary

Mechanisms of biological homeostasis are a model for how smart materials can be used in building skins that have the ability to tune themselves in response to environmental variations. This work describes processes for designing adaptive skin systems using smart materials including applying ecological models, establishing material parameters with haptic investigation, and digitally fabricating prototypes. These projects illustrate possibilities for using smart materials in adaptive systems to mediate socio-economic crises.

In this context, smart materials are those that change form or mechanical property in response to environmental stimuli. Because of their potential for reactive transformation, smart materials are appropriate elements for fluctuating, though not inherently homeostatic, skin systems. These projects demonstrate how designing with and for systematic change requires critical shifts in the conventional mind-set and means of design development.

To develop prototypes of adaptive building skins, we looked at ecological homeostasis on a variety scales, from cellular filtering processes such as osmosis to organism adaptation like the tropic behavior of plants as they move their leaves to adjust intake of heat and light. These examples helped us understand the nature of and possibilities for the design of responsive, adaptive skin systems.

In one prototype, Clifford [1] uses leaf stomata as a biological analogue to develop a responsive envelope that adjusts its porosity according to temperature fluctuations. The envelope operates as an array of thermally activated valves triggered at targeted temperatures that control surface porosity. The skin is Mylar laminated to a porous substrate and fitted with temperature-responsive Nitinol wire.
