Electrompolymeric Dynamic Display(ST10909)

Rensselaer Polytechnic Institute


Recent technological developments in dynamic glazing controls have made progress towards greater energy efficiency for curtain wall systems. However, these existing technologies are limited in their performance response to bioclimatic conditions because of their inability to adjust to the continuously shifting geometries and intensities of the solar rays. Recent developments in the emerging display technology may provide opportunities to transfer technology to glazing systems that can achieve high levels of precision and geometric selectivity through the building membrane in order to optimize the lighting, thermal and informational requirements of occupied spaces. Center for Architectural Sciences (CAS) researchers have been developing a window application of this technology under a previous NYSERDA grant and will continue to develop and refine applications with New Visual Media Group through this testing process.

Project Description

CAS will develop and demonstrate multi-pixel electropolymeric daylighting system insulated glazing units(EDDS IGUs) test samples that dynamically controls direct sunlight through a building envelope, which could lead to substantial energy savings by controlling daylight and solar heat gain, along with a potential reduction in electrical lighting loads. CAS will develop and demonstrate interior partitions incorporating single-pixel EDDS Units that dynamically allow deeper penetration of daylight into a building or various levels of opacity for privacy. These products will be tested using actual installed windows, mock test rooms, and occupancy surveys. The multi-pixel EDDS IGUs will also undergo extensive human factor testing to evaluate occupants’ satisfaction with the proposed product.


Previous analyses have suggested that smart windows with daylight dimming controls have the potential to provide significant energy and demand savings (approximately 25% savings in energy expenses).
