This Small Business Innovation Research (SBIR) Phase I project will demonstrate feasibility of creating surfaces that actively manage solar heat gain by switching between infrared transmittance and reflectivity. The ultimate objective is to develop skylights, windows, and roofsthat adapt to seasonal, regional, and diurnal changes in solar flux and heating and cooling requirements. The Phase I objective is to develop electrofluidic pigment materials systems incorporating infrared-reflecting particles and other infrared strategies. The infrared modulationperformance of these new materials systems will then be demonstrated in low cost electrofluidic modules. These modules change the optical properties of surfaces by moving pigment from a small area reservoir to full surface coverage in a similar manner to the way squids change their skin color. The innovation in this work is the development an entirely new materials system andmethod for managing near-infrared light over a large surface area.The broader impact/commercial potential of this project is to improve the energy efficiency of buildings. U.S. building energy consumption (40% of total U.S. Energy Consumption) can be reduced significantly by maximizing sunlight for lighting, while effectively managing solar heat gain. Current passive technologies (windows, insulation, paint, etc.) do not readily adapt toseasonal, regional, and diurnal changes in solar flux and heating and cooling requirements. By empowering buildings to actively manage solar heat gain, U.S. energy consumption can be reduced by more than 1 quadrillion BTU per year, while adding minimal cost to building infrastructure. There is also a large commercialization opportunity in selling active skylights, windows, roof tiles, etc. through partnerships with existing manufacturers.

这个小型企业创新研究（SBIR）第一阶段项目将展示通过在红外透射率和反射率之间切换来创建主动管理太阳能热增益的表面的可行性。最终目标是开发天窗、窗户和屋顶，以适应太阳能通量的季节性、区域性和昼夜变化以及加热和冷却要求。第一阶段的目标是开发包含红外反射颗粒和其他红外策略的电流体颜料材料系统。这些新材料系统的红外调制性能将在低成本的电流体模块中得到证明。这些模块通过将颜料从小面积储存器移动到全表面覆盖来改变表面的光学特性，其方式类似于鱿鱼改变皮肤颜色的方式。这项工作的创新之处在于开发了一种全新的材料系统和方法来管理大面积的近红外光。该项目更广泛的影响/商业潜力是提高建筑物的能源效率。美国建筑能耗（占美国总能耗的40%）可以通过最大限度地利用阳光照明，同时有效地管理太阳能热增益来显著降低。目前的被动技术（窗户、绝缘材料、油漆等）不容易适应季节性，区域性和日变化的太阳能通量和加热和冷却的要求。通过使建筑物能够积极管理太阳能热增益，美国的能源消耗每年可以减少超过1千分之一BTU，同时为建筑基础设施增加最小的成本。通过与现有制造商的合作伙伴关系，在销售活动天窗，窗户，屋顶瓦片等方面也有很大的商业化机会。
