This Small Business Innovation Research Phase II project will develop "Low Cost Smart Window Film" that reduces building energy consumption by dynamically optimizing solar gain. Low cost roll to roll processing techniques will be used to create unique electrochromic layers. The novel electrochromic layers will be scaled-up and used to construct insulated glass windows. Systematic characterization of the electrochromic film stability to UV and high temperature exposure will be evaluated and their long term reliability performance will be improved to meet the requirements. Upon successful completion of the project, the electrochromic windows expect to achieve enhanced solar modulation at fast switching speeds and manufactured at 2-3x lower cost than the currently available smart windows.The broader impact/commercial potential of this project pertains to residential and commercial buildings represent a prime opportunity to improve energy efficiency and sustainability worldwide. In the United States lighting and thermal management within buildings account for 20% of yearly energy consumption. The economic and environmental benefits of using electrochromic windows are clear: reducing one quad of energy use would yield an average savings of $10.6 billion, while eliminating about 21.5 gigawatts of power produced by fossil fuels and saving nearly 59 million metric tons of CO2 emissions. It is estimated that the use electrochromic windows in building can achieve a 50% reduction in peak energy demand and a 30% reduction in overall energy use. Still, current electrochromic windows in the market have not reached their market potential due to their high cost. Novel electrochromic windows are based on an innovative material system that increases performance while reducing production cost. Wide scale adoption of this technology will enhance market penetration for dynamic windows.

该小型企业创新研究第二阶段项目将开发“低成本智能窗膜”，通过动态优化太阳能增益来降低建筑能耗。低成本的卷对卷处理技术将用于产生独特的电致变色层。新型电致变色层将按比例放大并用于构造绝缘玻璃窗。将评估电致变色膜对紫外线和高温暴露的稳定性的系统表征，并将改善其长期可靠性性能以满足要求。该项目成功完成后，电致变色窗有望在快速开关速度下实现增强的太阳能调制，制造成本比目前可用的智能窗低2- 3倍。该项目对住宅和商业建筑的更广泛影响/商业潜力是提高全球能源效率和可持续性的主要机会。在美国，建筑物内的照明和热管理占年能耗的20%。使用电致变色窗户的经济和环境效益是显而易见的：减少四分之一的能源使用将平均节省106亿美元，同时消除约21.5千兆瓦的化石燃料产生的电力，并节省近5900万公吨的二氧化碳排放。 据估计，在建筑物中使用电致变色窗可以实现峰值能源需求减少50%，总体能源使用减少30%。尽管如此，目前市场上的电致变色窗由于其高成本而尚未达到其市场潜力。 新型电致变色窗基于一种创新的材料系统，可在提高性能的同时降低生产成本。这项技术的广泛采用将提高动态窗口的市场渗透率。
