The objective of this EFRI-SEED project is to develop a set of new switchable dyes and polymers as the basis for electrochromic windows (ECWs) and energy-harvesting (EH) ECWs which substantially reduce cooling/heating loads and increase human comfort. An secondary objective is to develop a partner methodology for moving towards the design of zero-energy buildings that transfers this new technology into educational programs for both the academic and building design communities. The project will develop EH-ECW technology by combining the merits of electrochromic window and dye-sensitized solar cell technologies for dimming control and to generate power to operate not only the ECWs but also other electrical systems. The researchers will study the fundamentals of sensor/controller systems for optimal use of the EH-ECWs in a given room, and the consideration of environmental life cycle impact into EH-ECW technology development and dissemination. The integration of EH-ECW systems into an autonomous building system is the basis for a new concept called "locally harvesting and locally used." The material systems studied promise substantial improvements over existing systems and will parallel component development with the use of Life Cycle Assessment (LCA). The LCA will form an overall framework to bring together the research and expertise of an interdisciplinary team including technology development and educational integration. The researchers will develop models to forecast environmental impacts for scaled fabrication sequences, performance for a variety of building types with the proposed ECW/EH-ECW systems and locations, and demolition systems. The research will investigate the use of EH-ECWs to generate a substantial portion of the energy used by buildings, thus reducing the impacts of central energy generation, and to increase visual comfort and building envelope performance resulting in healthier, more productive indoor environments, as well as to smooth the transfer of the above integrated technology to residential and commercial building design and the construction industry, targeting the $20B window market. This team plans to interact with the existing NSF centers, the Pacific Northwest National Laboratory, UW laboratories, a local architectural group and window company, the Seattle Science Center, and the University of Ulster (UU) as a foreign collaborator.The FY 2010 EFRI-SEED Topic that supports this project was sponsored by the US National Science Foundation (NSF) Directorates for Engineering (ENG), Mathematical and Physical Sciences (MPS) and Social, Behavioral and Economic Sciences (SBE), and Computer & Information Science and Engineering in collaboration with the US Department of Energy (DOE) and the US Environmental Protection Agency (EPA).

该 EFRI-SEED 项目的目标是开发一套新型可切换染料和聚合物，作为电致变色窗户 (ECW) 和能量收集 (EH) ECW 的基础，从而大幅减少冷却/加热负荷并提高人体舒适度。 第二个目标是开发一种合作伙伴方法，以实现零能耗建筑的设计，将这项新技术转移到学术界和建筑设计界的教育计划中。该项目将结合电致变色窗和染料敏化太阳能电池技术的优点来开发 EH-ECW 技术，用于调光控制和发电，不仅可以运行 ECW，还可以运行其他电气系统。 研究人员将研究传感器/控制器系统的基本原理，以便在给定房间内优化使用 EH-ECW，并将环境生命周期影响考虑到 EH-ECW 技术的开发和传播。 将 EH-ECW 系统集成到自主建筑系统中是“本地采集和本地使用”这一新概念的基础。研究的材料系统有望对现有系统进行重大改进，并将利用生命周期评估 (LCA) 并行组件开发。 LCA将形成一个整体框架，汇集跨学科团队的研究和专业知识，包括技术开发和教育整合。研究人员将开发模型来预测规模化制造序列的环境影响、拟议的 ECW/EH-ECW 系统和位置以及拆除系统的各种建筑类型的性能。该研究将调查使用 EH-ECW 来产生建筑物所使用的大部分能源，从而减少中央能源产生的影响，并提高视觉舒适度和建筑围护结构性能，从而创造更健康、更高效的室内环境，并顺利地将上述集成技术转移到住宅和商业建筑设计和建筑行业，目标是 20B 美元的窗户市场。该团队计划与现有的 NSF 中心、太平洋西北国家实验室、威斯康星大学实验室、当地建筑集团和窗口公司、西雅图科学中心以及阿尔斯特大学 (UU) 作为外国合作者进行互动。支持该项目的 2010 财年 EFRI-SEED 主题由美国国家科学基金会 (NSF) 工程 (ENG)、数学和物理科学 (MPS) 和社会科学理事会赞助， 行为与经济科学 (SBE) 以及计算机与信息科学与工程与美国能源部 (DOE) 和美国环境保护局 (EPA) 合作。
