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

这个小企业创新研究（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，这种涂料有可能显著减少温室气体排放。由于政府和对能源和环境设计认证结构的领导需求的快速增长，节能涂料市场正在加速增长。随着这些最新的发展，建筑开发商正在积极寻求技术上强大且具有成本效益的解决方案，以满足能源要求。这些新颖的建筑涂料不仅提供了传统建筑涂料的美学和质感，而且还为建筑业主提供了减少加热和冷却相关成本的额外好处。这个小企业创新研究（SBIR）第一阶段项目的重点是开发一种相变材料的优化混合物，用于建筑围护结构涂料，如油漆、石膏和灰泥，以提供隔热性能。优化的混合物将由具有不同相变温度的相变材料（pcm）以特定体积比例组成，以在特定气候区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，并将高峰负荷转移到非高峰时段，这可以显著节省成本。该项目将制定方案，在不影响其美观的情况下，最大限度地将pcm掺入这些涂料中。能量建模和实验工作，包括微观和宏观尺度的材料表征，将进行，以验证这些涂层的实验室和小现场规模的性能。该奖项反映了美国国家科学基金会的法定使命，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。

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.
