Dynamic Systems

Controlling solar heat gain associated with daylight is a significant challenge. In order to offset building heating and

cooling loads associated with diurnal and seasonal variations in climate, a range of adaptable responses at the window

is required. In contrast to existing dynamic building envelope technologies, emerging display technologies have the potential to actively reconfigure their basic patterns to respond to fluctuating bioclimatic flows while simultaneously adjusting to the changing visual desires of occupants. Recently developed thin-film electro electropolymeric display prototypes demonstrate a significant new opportunity for dynamic façade applications that enable instantaneously switchable patterns to be embedded within the surfaces of insulated glazing units.


In order to keep pace with rapidly advancing research towards responsive building technologies on multiple fronts, new robust frameworks are required to address the multi-scalar complexity, environmental, and socio-cultural performance possibilities inherent within their material behavior. In exploring methods to integrate bioclimatic and biological inputs in the design and testing of highly responsive technologies such as the Electroactive Dynamic Display System (EDDS), addressing environmental modulation, building demands, design intentions, and the diverse preferences of building inhabitants is essential. Our design methodology investigates these challenges through a visually immersive computational framework that integrates both quantitative and qualitative real-time feedback into the design and testing procedures for developing next-generation bioresponsive building envelopes.
