This PFI: AIR Technology Translation project focuses on translating the remarkable tunability of the abruptly discontinuous metal-insulator transitions of binary and ternary vanadium oxides discovered upon scaling to finite size and upon incorporation of substitutional/intercalative dopants to fill a critical technology gap in their deployment as dynamic glazing components of thermally switchable fenestration (doors, windows, and glazed skylights). The translated smart window technology has the following unique features: thermally switchable heat-blocking properties without a significant change in visible light transmittance, tunability of the switching temperature to meet the needs of different geographic climates, and voltage-driven induction of heat-blocking properties that provides exemplary savings in air-conditioning costs while allowing natural daylight to be used to light interiors of buildings when compared to the leading competing electrochromic and static metallic coatings in this market space. The project accomplishes this goal by enabling investigation of scale-up of the synthesis of vanadium oxides, identification of optimal coating deposition methods, and allowing correlation curves and data tables to be compiled relating critical performance metrics to coating thickness and density resulting in a prototype energy efficient window. The partnership engages a leading manufacturer of home windows, the Technology Accelerator Fund, and the Office of Science, Technology Transfer, and Economic Outreach at the University at Buffalo to provide guidance in the fenestration industry and other aspects such as market adoption, commercialization, and insulating glass unit design as they pertain to the potential to translate the smart window technology along a path that may result in a competitive commercial reality. The potential economic impact is expected to be ca. $118 Million in the next 4 years, which will contribute to the U.S. competitiveness in this area of green building materials and energy efficient buildings. The societal impact, long term, will be more energy efficient (even zero emission) buildings with a reduced carbon footprint and energy savings that have been estimated by some accounts to be as much as 1.0 quadrillion BTUs.

这个PFI: AIR技术翻译项目的重点是翻译二元和三元钒氧化物突然不连续的金属绝缘体转变的显著可调性，这些转变是在缩放到有限尺寸时发现的，并且在加入替代/插入掺杂剂时发现的，以填补其作为热开关开窗（门、窗和玻璃天窗）的动态玻璃组件部署中的关键技术空白。翻译后的智能窗技术具有以下独特之处：与市场上领先的电致变色和静态金属涂层相比，可热切换的热阻隔性能在可见光透过率没有显著变化的情况下，可调节开关温度以满足不同地理气候的需求，以及电压驱动的热阻隔性能，提供了典型的空调成本节约，同时允许自然光用于照亮建筑物内部。该项目通过研究钒氧化物合成的规模，确定最佳涂层沉积方法，并允许编制与涂层厚度和密度相关的关键性能指标的相关曲线和数据表，从而实现了这一目标，从而实现了原型节能窗口。该合作伙伴关系涉及一家领先的家用窗户制造商、技术加速器基金和布法罗大学的科学、技术转移和经济推广办公室，为开窗行业和其他方面提供指导，如市场采用、商业化和中空玻璃单元设计，因为它们涉及将智能窗户技术转化为可能导致竞争的商业现实的潜力。预计未来4年的潜在经济影响约为1.18亿美元，这将有助于美国在绿色建筑材料和节能建筑领域的竞争力。从长远来看，社会影响将是更节能（甚至是零排放）的建筑，减少碳足迹，节省能源，据一些人估计，节省能源可达1千万亿btu。
