This Small Business Innovation Research Phase I project will develop a low-cost nanostructured smart window coating that reduces building energy consumption by dynamically optimizing solar gain. Scalable solution processed techniques will be used to create unique nanostructured electrochromic layers. The novel electrochromic layers will be initially examined for compatibility and performance then subsequently used to construct solid state energy efficient windows. Systematic characterization of the solid state electrochromic device will identify components in the system which are performance limiting. Upon successful fabrication, the electrochromic windows expect to achieve enhanced solar modulation at fast switching speeds. The broader impact/commercial potential of this project pertains to residential and commercial buildings, representing a prime opportunity to improve energy efficiency and sustainability worldwide. Currently, lighting and thermal management within buildings accounts for 20% of domestic energy consumption. The economic and environmental benefits of using electrochromic windows are clear: reducing one quad (one quadrillion BTUs) of energy use would yield an average savings of $10.6 billion, while eliminating the need for 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 of 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. The novel electrochromic windows in this project are based on an innovative design that increases lifetime and performance while reducing production cost. Wide scale adoption of this unique technology will not only enhance market penetration for dynamic windows, but will establish a new benchmark for performance and cost.

这个小型企业创新研究阶段I项目将开发低成本的纳米结构智能窗涂层，该涂层通过动态优化太阳能增益来降低建筑能源消耗。 可扩展的解决方案处理技术将用于创建唯一的纳米结构的电致色层。 最初将检查新型的电致色层的兼容性和性能，然后用来构建固态节能窗口。固态电致色素设备的系统表征将识别系统中性能限制的组件。成功制造后，电染色窗期望在快速开关速度下实现增强的太阳能调制。该项目的更广泛的影响/商业潜力与住宅和商业建筑有关，这代表了提高全球能源效率和可持续性的主要机会。 目前，建筑物内的照明和热管理占国内能源消耗的20％。 使用电染色窗的经济和环境益处很明显：减少1个四分之一的能源利用（一百千万亿吨）将产生106亿美元的平均节省，同时消除了对大约21.5 gigawatts of Fossil燃料产生的功率的需求，并节省了近5900万吨的CO2二氧化碳量。 据估计，在建筑物中使用电染色窗可以减少50％的峰值能源需求，并降低总体能源利用。 尽管如此，由于其高成本，目前市场上当前的电致色窗未达到其市场潜力。 该项目中的新型电致色素窗口基于一种创新的设计，该设计在降低生产成本的同时提高了寿命和性能。大规模采用这种独特的技术不仅会增强动态窗口的市场渗透率，而且还将为性能和成本建立新的基准。
