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.

这项小型企业创新研究（SBIR）II期项目的更广泛的影响/商业潜力将通过直接降低大型工业设施，商业建筑，校园和房屋所需的能源消耗来观察。由于经过精心设计的辐射特性，由于降低了冷却需求的减少，随着安装被动辐射复合材料（PRC）屋顶材料的建筑能源管理，联邦和行业设施的可持续性将得到显着提高。每年对凉爽屋顶材料的市场需求超过10亿美元，预计随着需求的增加和投资回报率而增长。由于对商业凉爽屋顶产品的最先进选择以及在中国概念设计阶段确定的经济制造方法，中国屋顶材料可以期望在不断增长的行业中竞争。机会范围超出了结构性热管理，到包括冷藏运输和存储在内的各种冷却需求。中国屋顶的发展将提高理解和使用旨在智能控制热辐射的频谱选择性材料。拟议的项目将提供将PRC技术转移到商业部门所需的关键设计，测试和实验验证。基于电磁和热建模的设计包括能够提供每平方米安装材料100瓦的无源辐射通量的复合材料选项。相对于当前的商业冷却屋顶材料，这种被动冷却优势有望为气候控制结构提供大量的长期成本节省，并减少化石燃料使用情况。旨在进行频谱选择性的PRC材料特性通过反射太阳能和辐射光谱的近红外部分为智能热管理提供了机会，同时在8-13微米大气传输窗口中强烈发射。 SBIR项目的一个主要目的是考虑具有三个标准的全光谱特性的优化PRC设计：热效率提高，耐用性和较大的批处理制造经济。在全尺度测试结构上的基于PRC的屋顶材料的演示将量化被动冷却能力和对风化的鲁棒性，将基于PRC的屋顶定位为商业制造合作伙伴的介绍。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的智力和更广泛影响的评估来进行评估的审查审查的审查Criteria，这是值得的。
