AIR Option 1: Technology Translation: Smart Windows for the Improved Energy Efficiency of Buildings

这个PFI：空气技术翻译项目专注于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大小并加入替代/插层掺杂剂以填补其作为热可切换窗口(门、窗和上釉天窗)动态玻璃组件部署的关键技术空白时发现的。转换后的智能窗技术具有以下独特功能：可热切换的隔热性能而不会显著改变可见光透过率；切换温度可调以满足不同地理气候的需求；电压驱动感应隔热特性，与该市场领域领先的电致变色和静电金属涂料相比，可在节省空调成本的同时允许利用自然光为建筑物内部照明。该项目通过以下方式实现这一目标：能够扩大合成钒氧化物的规模，确定最佳涂层沉积方法，并能够编制相关曲线和数据表，将关键性能指标与涂层厚度和密度联系起来，从而形成原型节能窗口。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科学、技术转移和经济外展办公室，以提供窗口业和其他方面的指导，如市场采用、商业化和中空玻璃单元设计，因为这些方面与将智能窗技术转化为可能导致竞争性商业现实的道路有关。预计未来4年潜在的经济影响约为1.18亿美元，这将有助于美国在这一绿色建材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(甚至零排放)的建筑，减少了碳足迹，一些账户估计节省的能源高达1.0万亿BTU。

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.
