This grant provides funding for the development of a novel dynamic window technology for energy efficient buildings. Dynamic windows can accomplish three essential functions. First, they can efficiently harvest visible light to minimize electricity use during daylight. Second, they block solar heat from entering buildings in the summertime and thus can lower energy use for cooling. Third, in the wintertime, they let heat in to reduce heating costs. These innovative windows are inspired by the mature heat pipe and novel photonic crystal technologies. Heat pipes have been widely used in managing the flow of heat in a wide range of products such as air conditioners and refrigerators. Photonic crystal is a new class of optical materials designed for controlling the flow of light. A scalable doctor blade coating nanomanufacturing platform will also be developed for making large-area photonic crystal coatings on window glass. The results of this research will lead to significant breakthroughs in improving energy efficiency of windows for both residential and commercial buildings. Windows are one of the main sources of energy loss in buildings. On average, they account for 36 percent of overall building heating and cooling loads. Consequently, this research will contribute to reduce the consumption of oil, natural gas, and electricity needed to power buildings. This could greatly enhance the energy security of the United States. Buildings contribute about 40 percent of U.S. carbon emission. This novel dynamic window technology could significantly reduce their impact on the environment. Moreover, the scalable doctor blade coating nanomanufacturing platform will advance many other areas ranging from high-speed optical computing to ultrasensitive bio-sensing, where the inexpensive fabrication of large-area periodic nanostructures is important.

这笔赠款为开发节能建筑的新型动态窗户技术提供资金。动态窗口可以完成三个基本功能。 首先，它们可以有效地收集可见光，以最大限度地减少白天的用电量。 其次，它们在夏季阻止太阳热量进入建筑物，从而可以降低冷却能耗。 第三，在冬天，他们引入热量以降低取暖成本。这些创新窗户的灵感来自成熟的热管和新颖的光子晶体技术。 热管已广泛用于管理空调和冰箱等多种产品的热量流动。 光子晶体是一种新型光学材料，旨在控制光的流动。还将开发可扩展的刮刀涂层纳米制造平台，用于在窗玻璃上制造大面积光子晶体涂层。 这项研究的结果将为提高住宅和商业建筑窗户的能源效率带来重大突破。 窗户是建筑物能源损失的主要来源之一。 平均而言，它们占整个建筑供暖和制冷负荷的 36%。 因此，这项研究将有助于减少建筑物供电所需的石油、天然气和电力的消耗。这可以大大增强美国的能源安全。 建筑物排放量约占美国碳排放量的 40%。这种新颖的动态窗户技术可以显着减少它们对环境的影响。 此外，可扩展的刮刀涂层纳米制造平台将推动从高速光学计算到超灵敏生物传感等许多其他领域的发展，其中大面积周期性纳米结构的廉价制造非常重要。
