Lead Performer: Polyceed – Tucson, AZ
Partner: National Renewable Energy Laboratory – Golden, CO
Project Term: May 1, 2019 – July 31, 2022
Funding Type: Funding Opportunity
Project Objective
In this project, Polyceed, with support from the National Renewable Energy Laboratory (NREL), will develop low-cost, high-performance electrochromic devices for building window technologies. The project team will focus on the integration and engineering of a novel electrochromic active layer into device structures (including insulated glass units), while also meeting occupant aesthetic, cost, and durability requirements. Durability based on temperature, illumination, and cycling conditions will be demonstrated under maximum stress conditions by leveraging NREL’s advanced fenestration durability research capabilities. The ultimate goal of this project is to fabricate a device with an electrochromic active layer that passes ASTM E2141 with a targeted solar heat gain coefficient when incorporated in an IGU of 0.5 or greater in the bleached state and less than 0.1 in the colored state.
Project Impact
This project will work to overcome some of the critical drawbacks of current electrochromic windows by reducing product costs and improving product aesthetics. These advancements will increase adoption of these electrochromic technologies, which can improve occupant comfort, increase energy efficiency, and maximize access to daylight and outdoor views.
