The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project will be observed through a direct reduction in the energy consumption required by large industrial facilities, commercial buildings, campuses, and homes. Due to reduced cooling demands as a result of carefully designed radiative properties, the sustainability of federal and industry facilities will be significantly improved with the installation of passive radiative composite (PRC) roofing material for building energy management. The market demand for cool roofing materials has exceeded $1 Billion, annually, and is expected to grow with increasing need and return on investment. PRC roofing material can expect to compete in a growing industry due to non-trivial improvement over state-of-the-art options in commercial cool roofing products and the economic fabrication method identified in the PRC conceptual design stage. Opportunities extend beyond structural thermal management to a variety of cooling needs including refrigerated transportation and storage. The development of PRC roofing will advance understanding and use of spectrally-selective materials designed for intelligent control of thermal radiation. The proposed project will provide critical design, testing, and experimental validation needed to transition PRC technology into the commercial sector. Designs based on electromagnetic and thermal modeling include composite material options capable of providing passive radiative flux of over 100 Watts per square meter of installed material. This passive cooling advantage, relative to current commercial cool roofing materials, is expected to create significant long-term cost savings and reduction in fossil fuel usage for climate controlled structures. PRC material properties designed to be spectrally selective offer the opportunity for intelligent thermal management through reflection of solar and near-infrared portions of the radiative spectrum, while emitting strongly in the 8-13 micron atmospheric transmission window. A primary objective of the SBIR project is to optimize PRC designs considering full spectrum properties with three criteria in mind: thermal efficiency improvement, durability, and large batch manufacturing economy. Demonstration of PRC-based roofing materials on full-scale test structures will quantify passive cooling power and robustness to weathering, positioning PRC-based roofing for introduction by a commercial manufacturing partner.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.

这个小型企业创新研究（SBIR）第二阶段项目的更广泛的影响/商业潜力将通过直接减少大型工业设施，商业建筑，校园和家庭所需的能源消耗来观察。由于精心设计的辐射性能降低了冷却需求，安装被动辐射复合（PRC）屋顶材料用于建筑能源管理将显著提高联邦和工业设施的可持续性。对凉爽屋顶材料的市场需求每年已超过10亿美元，预计将随着需求和投资回报的增加而增长。中国屋顶材料有望在不断增长的行业中竞争，这是由于在商业凉爽屋顶产品的最先进选择方面取得了重大改进，以及在中国概念设计阶段确定了经济的制造方法。机会从结构热管理扩展到各种冷却需求，包括冷藏运输和储存。PRC屋顶的发展将促进对用于智能控制热辐射的光谱选择性材料的理解和使用。拟议的项目将提供关键的设计，测试和实验验证所需的中国技术过渡到商业部门。基于电磁和热建模的设计包括复合材料选项，能够提供每平方米安装材料超过100瓦的被动辐射通量。相对于目前商用的冷屋顶材料，这种被动冷却的优势有望为气候控制结构带来显著的长期成本节约和化石燃料使用的减少。PRC材料的光谱选择性设计为通过反射辐射光谱的太阳能和近红外部分，同时在8-13微米的大气传输窗口中强烈发射，提供智能热管理的机会。SBIR项目的主要目标是优化PRC设计，考虑全光谱特性，考虑三个标准：热效率提高，耐用性和大批量生产经济性。在全尺寸测试结构上对PRC基屋顶材料的演示将量化被动冷却能力和耐候性，将PRC基屋顶定位为商业制造合作伙伴的介绍。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。
