Building heating, ventilation, and air conditioning accounted for 14 percent of primary energy consumption in the United States in 2013 according to the U.S. Department of Energy. Windows take a large fraction of the building surface and are a major source of heat energy loss. The current technologies rely upon double-panes with an insulating gas in between to reduce energy consumption. The single-pane windows are more desirable for reasons including lighter weight, straightforward manufacturing, easy installation and maintenance, and less materials needed. The objective of this research aims to reduce heat transfer through single panes by lowering the temperature difference between the glass inner surface and inside of the room. This is achieved by applying a thin coating of iron oxide nanoparticles onto the glass surface to generate heat through sunlight or artificial light. The single-pane window coated with nanoparticle would greatly lower the energy consumption in buildings and homes, and revolutionize the current window technology. The research team will recruit underrepresented students to participate in this multidisciplinary project. The goal of the project is to understand the photonic physics that dictates the photothermal effect of nanoparticles under a wide spectrum of light and its effects on thermal performance for energy efficient window technology. This study will provide a fundamental base on light to heat conversion for optimization of the photothermal effect. Factors governing the photothermal effect will be investigated in terms of the nanoparticle size, concentration and dispersion, morphology, and surface properties. The relationship between photothermal heating on the optical and thermal properties of windowpanes coated with nanoparticles will be established through both computational simulation and physical experiments by varying the air temperature, wavelength of irradiation, irradiation power, and nanoparticle concentrations for optimum building energy efficiency.

根据美国能源部的数据，2013年建筑供暖、通风和空调占美国一次能源消耗的14%。窗户占据了建筑物表面的很大一部分，是热能损失的主要来源。目前的技术依赖于双层玻璃，中间有绝缘气体，以减少能源消耗。单窗格窗户更受欢迎的原因包括重量较轻，制造简单，易于安装和维护，以及所需材料较少。本研究的目的是通过降低玻璃内表面和室内的温差来减少通过单个窗格的热传递。这是通过在玻璃表面涂上一层薄薄的氧化铁纳米颗粒涂层来实现的，通过阳光或人造光产生热量。涂有纳米粒子的单层窗将大大降低建筑物和家庭的能源消耗，并彻底改变目前的窗户技术。研究小组将招募代表性不足的学生参加这个多学科项目。该项目的目标是了解光子物理学，该物理学决定了纳米粒子在宽光谱下的光热效应及其对节能窗户技术热性能的影响。本研究为优化光热效应提供了光热转换的基础。控制光热效应的因素将在纳米颗粒的尺寸，浓度和分散，形态和表面性质方面进行研究。光热加热对涂覆有纳米颗粒的窗玻璃的光学和热特性之间的关系将通过计算模拟和物理实验来建立，通过改变空气温度、照射波长、照射功率和纳米颗粒浓度来获得最佳的建筑物能源效率。
