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.

这个小企业技术转让（STTR）第一阶段项目的更广泛的影响/商业潜力是对低性能旧建筑进行可持续和经济的改造，以改善建筑环境的经济，社会和生态影响。超过一半的商业建筑是在20世纪80年代以前建造的，能源标准较低。 这些建筑物的业主和居住者现在经常寻求更好的能源管理和空气质量技术。该一期项目开发的微藻窗是一种节能、易于安装、适应性强的模块化单元，适用于不同的改造应用，由于其良好的空气质量和可再生能源潜力，能够与传统窗户竞争。据估计，微藻窗改造将大大提高工人的生产率，由于建筑围护结构的改善，建筑物的销售或租赁价值预计将显著增加。这一小企业技术转让（STTR）第一阶段项目旨在开发一种创新的、具有成本效益的微藻窗，用于改造低性能的商业窗户。微藻是一种有效的碳捕获和光合生产生物质的生物系统。微藻窗在窗组件内结合了填充有微藻的筛网网络，以替换或添加到旧窗，从而进行节能改造。窗组件内的微藻屏能够平衡隔热、日光透射、遮阳功效和向外观看的多种功能。研究目标是：1）描述1980年以前办公室改造应用的最佳微藻窗户系统; 2）根据行业标准，使用计算机模拟和实验室实验验证环境性能; 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。 新的微藻窗减轻了室内和室外环境之间的能量转移，从而减少了供暖、制冷、照明和通风需求。该奖项反映了NSF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。
