PFI-TT: High performance, regenerative windows for building energy reduction and clean energy production

创新伙伴关系-技术转化（PFI-TT）项目的更广泛影响/商业潜力通过建筑节能、可再生能源生产和减少污染物，提供更广泛的环境、社会和商业影响。商业窗户极大地增加了建筑内部的加热和冷却负荷，同时影响了居住者的视觉和热舒适。随着人口和新建筑的增长导致化石燃料的使用和人为排放的增加，清洁能源的发展是一个重要的优先事项。该项目有望改善现场可再生能源生产，以帮助应对全球变暖。美国商业窗户的建筑市场估计每年约为30亿美元。随着能源效率和发电量的提高，拟议的再生窗有可能通过产生清洁电力和减少制冷、供暖和人工照明负荷来节省前期和运营成本，使建筑物对业主、行业专业人士和利益相关者更具吸引力。该系统的美化预期将进一步增加公众使用的广泛采用。该项目通过美观有趣、功能创新的窗户为节能、健康的生活环境做出贡献。该项目旨在开发一种新型的高性能可再生窗户，与气候响应太阳能电池相结合，以提高现场清洁能源生产和建筑能源效率。城市建筑的垂直表面为利用太阳能提供了一个绝佳的位置。与传统的双层玻璃窗户不同，拟议的窗户能够针对各种性能需求进行优化——节能、现场发电和用户满意度。该系统包含一个封闭的空气腔，其中太阳能电池安装在一个有条件的封闭空气空间中，以防止热量积聚，灰尘积聚和水分形成，从而提高能量转换效率和系统寿命。除了提高能量转换效率和系统寿命外，该系统还有望产生高热性能，良好的遮阳效果，采光渗透和隔音。该系统还旨在通过提供改进的美学外观、视野和日光照明来促进广泛的建筑应用和用户满意度，从而影响建筑居住者的健康、福祉和生产力。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project offers broader environmental, societal, and commercial impacts through building energy savings, renewable power production, and pollutant reductions. Commercial windows significantly contribute to an increase in heating and cooling loads inside the building while affecting visual and thermal comfort to the occupants. The development of clean energy is an important priority as the growing population and new construction lead to a rise in fossil fuel use and anthropogenic emissions. This project is expected to improve on-site renewable energy production to help combat global warming. The US construction market for commercial windows is estimated at around $3 billion annually. With enhanced energy efficiency and power production, the proposed regenerative windows have the potential to save both upfront and operational cost by producing clean electricity and reducing cooling, heating, and artificial lighting load, making buildings more appealing to building owners, industry professionals, and stakeholders. Aesthetic enhancement of the system is expected to further increase widespread adoption of public use. The project is contributing to an energy-efficient, healthy living environment through aesthetically intriguing, functionally innovative windows.This project seeks to develop a novel high-performance regenerative window integrated with climate responsive solar cells to improve on-site clean energy production and building energy efficiency. The vertical surface of urban buildings offers a prime location to harness solar energy. Unlike traditional double-pane windows, the proposed windows are able to be optimized for various performance needs – energy savings, on-site power production, and user satisfaction. The system incorporates a closed air cavity where solar cells are installed in a conditioned, closed air space to prevent heat build-up, dust accumulation, and moisture formation resulting in high energy conversion efficiency and system longevity. In addition to the enhanced energy conversion efficiency and system longevity, the system is expected to yield high thermal performance, good shading efficacy, daylighting penetration, and acoustic insulation. The system is also designed to promote wide architectural application and user satisfaction by providing improved aesthetic appearance, and view-out and daylight illuminance, impacting the health, well-being, and productivity of building occupants.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
