The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase I project is in the sustainable and economic retrofitting of low-performing older buildings toward improved economic, social and ecological impacts of built environments. More than half of all commercial buildings were constructed before the 1980s with lower energy standards. The owners and occupants of these buildings now often seek better energy management and air quality technologies. The microalgae window developed in this Phase I project is an energy-efficient, easy-to-install, adaptable modular unit for different retrofitting applications, able to compete with conventional windows due to its good air quality and renewable energy potentials. Gains in worker productivity from microalgae window retrofit are estimated to be substantial and building values at sale or rental are expected to increase significantly due to building envelope improvement.This Small Business Technology Transfer (STTR) Phase I project seeks to develop an innovative, cost-effective microalgae window for retrofitting low-performing commercial windows. Microalgae are an effective biological system for carbon capture and biomass production from photosynthesis. The microalgae window incorporates a network of screens filled with microalgae within a window assembly to replace or add to older windows for energy-efficient retrofitting. The microalgae screen within a window assembly is able to balance multiple functions of thermal insulation, daylight transmission, solar shading efficacy, and views to outside. Research objectives are to: 1) characterize the optimal microalgae window system for pre-1980 office retrofitting applications; 2) verify environmental performance using computer simulations and lab experimentation in accordance with industry standards; and 3) conduct field testing to evaluate building energy savings, indoor air quality improvement and renewable energy production potentials. The new microalgae window mitigates energy transfer between indoor and outdoor environments, subsequently reducing heating, cooling, lighting, and ventilation demands.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.

这一小型企业技术转移（STTR）I期项目的更广泛的影响/商业潜力在于，较低的较旧建筑的可持续性和经济改造，以改善建筑环境的经济，社会和生态影响。所有商业建筑中有一半以上是在1980年代之前建造的，具有较低的能源标准。 这些建筑物的所有者和居民现在经常寻求更好的能源管理和空气质量技术。在此I阶段项目中开发的微藻窗口是一个节能，易于安装的，适应性的模块化单元，用于不同的改装应用，由于其良好的空气质量和可再生能源电位，能够与常规窗户竞争。据估计，从微藻窗口改造中获得的工人生产力的提高是实质性的，并且由于建筑物的构造改善而预计​​销售或租赁的建筑价值将显着提高。该小型企业技术转移（STTR）I阶段项目旨在开发创新的，具有成本效益的微型微型窗口，以改造低迷的出色商业窗户。微藻是从光合作用中捕获碳和生物量的有效生物系统。微藻窗口包含了一个屏幕网络，窗口组件中充满微藻的屏幕网络，以更换或添加到较旧的窗口中进行节能改造。窗口组件中的微藻屏幕能够平衡热绝缘，日光传输，太阳阴影功效以及外部视图的多个功能。研究目标是：1）表征1980年以前的办公室改造应用程序的最佳微藻窗口系统； 2）使用计算机模拟和实验室实验验证环境绩效； 3）进行现场测试，以评估建筑节能，室内空气质量改善和可再生能源生产潜力。 新的微藻窗口减轻了室内和室外环境之间的能量转移，随后降低了供暖，冷却，照明和通风需求。这项奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来通过评估来支持的。
