The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is in enabling additional energy savings in buildings by harvesting natural daylight and using it for illuminating the interior space with high efficiency and without glare, thus offsetting the need for electrical lighting. This will make building operations more sustainable and help improve the energy security of the U.S, create jobs, and reduce greenhouse gas emissions. Additionally, when commercially available, this new technology will bring all of the well-known benefits of enhanced natural lighting for occupants of millions of residential and commercial buildings across the U.S., such as connection to outdoors and improved comfort, productivity and well-being, thus benefiting many groups of consumers.The proposed project will demonstrate the feasibility of a novel, non-prismatic optical film material and its use for enhanced daylighting harvesting in buildings. This material employs thousands of microscopic reflective surfaces embedded into the bulk of the material and operates by capturing the incident sunlight and projecting it deep into the building interior. Commercial buildings alone consume about 20 percent of all energy used in the United States at an estimated cost of nearly $180 billion. Building interior lighting accounts for around 30% of that cost. By applying the daylight-harvesting optical material to windows of building facades, a significant fraction of that energy consumption can be offset using the natural light captured throughout the day. The project will provide the critical design, testing, and experimental validation needed to transition the technology into the commercial sector. The primary objective of the project is to develop the core light-redirecting material and associated micro-optical fabrication technology that can be subsequently scaled for low-cost mass production. A second objective is to develop, test and demonstrate a prototype daylight-harvesting window film product based on this material.

这个小型企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力是通过收集自然日光并将其用于高效且无眩光的室内照明，从而抵消对电气照明的需求，从而实现建筑物的额外节能。这将使建筑运营更具可持续性，并有助于改善美国的能源安全，创造就业机会，减少温室气体排放。此外，当商业化时，这项新技术将为美国数百万住宅和商业建筑的居住者带来增强自然照明的所有众所周知的好处，例如与户外的连接以及改善的舒适度、生产力和幸福感，从而使许多消费者群体受益。该拟议项目将展示一种新型非棱镜光学薄膜材料的可行性及其在建筑物中用于增强日光收集的用途。这种材料采用了数千个嵌入到材料主体中的微观反射表面，并通过捕获入射阳光并将其投射到建筑物内部深处来运作。仅商业建筑就消耗了美国所有能源的20%，估计成本近1800亿美元。建筑内部照明约占该成本的30%。通过将日光捕获光学材料应用于建筑物立面的窗户，可以使用全天捕获的自然光抵消很大一部分能源消耗。该项目将提供关键的设计，测试和实验验证所需的技术过渡到商业部门。该项目的主要目标是开发核心光重定向材料和相关的微光学制造技术，随后可以进行低成本大规模生产。第二个目标是开发、测试和展示基于这种材料的日光捕获窗膜产品原型。
