SBIR Phase I: Composite Coatings for Improving Energy Efficiency of Building Envelope Systems

这个小型企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力是开发节能建筑涂料，这些涂料有可能显著减少温室气体排放。节能涂料市场正在经历加速增长，由于政府和快速增长的需求领导能源和环境设计认证的结构。随着这些最新的发展，建筑开发商正在积极寻求技术强大且具有成本效益的解决方案，以满足能源需求。这些新型建筑涂料不仅具有传统建筑涂料的美观性和质感，而且还为建筑业主提供了降低供暖和制冷相关成本的额外好处。这个小型企业创新研究（SBIR）第一阶段项目的重点是开发一种优化的相变材料混合物，用于建筑围护涂料，如油漆，石膏和灰泥，以使它们具有绝缘性能。优化的混合物将由具有不同相变温度的相变材料（PCM）组成，以特定的体积比例，在特定的气候区域中最大限度地节省加热和冷却成本。初步的实验室工作表明，PCM可以用于涂料，以减少温度波动，并将峰值负荷转移到非峰值时间，这可以导致显着的成本节约。 该项目将开发协议，以最大限度地将PCM纳入这些涂层，而不影响其美观性。能源建模和实验工作，包括微观和宏观尺度的材料表征将进行验证实验室和小现场规模的性能，这些涂层。这个奖项反映了NSF的法定使命，并已被认为是值得支持的，通过评估使用基金会的知识价值和更广泛的影响审查标准。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is the development of energy efficient building coatings that have the potential to significantly reduce greenhouse gas emissions. The market for energy efficient coatings is experiencing accelerated growth due to government and rapid rise in demand for Leadership in Energy and Environmental Design certified structures. With these recent developments, building developers are actively seeking solutions which are technologically robust and cost-effective for meeting energy mandates. These novel architectural coatings not only provide the aesthetics and textured finish as traditional architectural coatings, but also provide the added benefit of decreasing heating and cooling related costs for the building owner.This Small Business Innovation Research (SBIR) Phase I project is focused on developing an optimized blend of phase change materials for incorporation in architectural building envelope coatings such as paint, plaster and stucco, to provide them with insulative properties. The optimized blend will consist of phase change materials (PCMs) with different phase transition temperatures in specific volume proportions to maximize energy savings in a specific climate zone in terms of heating and cooling costs. Preliminary lab work has shown promise that PCMs can be utilized in coatings to reduce temperature swings and shift the peak load to off-peak hours, which can lead to significant cost savings. This project will develop protocols to maximize incorporation of PCMs in these coatings without compromising their aesthetics. Energy modeling and experimental work including micro- and macro- scale material characterization will be carried out to verify the laboratory and small field-scale performance of these coatings.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.
