Abstract

When exposed to light sources, photochromic (PC) materials change their optical properties and can lessen the transmission of UV and infrared radiation. This results in optimal thermal comfort and a pleasing visual contrast between the internal and external settings. This study uses computer modeling to analyze the annual energy usage in a home with natural ventilation in order to compare the effectiveness of photochromic films with commercial glass. The study is carried out using the EnergyPlus program in the cities of São Carlos and Cuiabá ‐ Brazil. Experiments and numerical simulations with data from doped and undoped tungsten trioxide (WO3) PC films are used in the study. Given the rise in energy usage and the pursuit of thermal comfort, this method is essential for assessing the thermal performance of buildings. Evaluations included a comparison of air conditioner performance and energy savings analysis, which leads to a noteworthy annual reduction in energy usage of up to 216.55 kWh and a 40% improvement in visual comfort. It is determined that PC film's dynamic behavior is the best option for comfort in terms of heat, illumination, and visual comfort.

掺杂和未掺杂 WO3 光致变色薄膜的表征和能量性能

当暴露在光源下时，光致变色（PC）材料会改变其光学特性，减少紫外线和红外线辐射的透过。这样就能获得最佳的热舒适度，并在内外环境之间形成令人愉悦的视觉对比。本研究利用计算机建模分析了自然通风住宅的年能耗，以比较光致变色膜与商用玻璃的效果。研究使用 EnergyPlus 程序在巴西圣卡洛斯市和库亚巴市进行。研究采用了掺杂和未掺杂三氧化钨（WO3）PC 薄膜的实验和数值模拟数据。鉴于能源使用的增加和对热舒适度的追求，这种方法对于评估建筑物的热性能至关重要。评估包括空调性能比较和节能分析，结果表明每年可减少高达 216.55 千瓦时的能源消耗，视觉舒适度提高了 40%。结果表明，PC 薄膜的动态特性是热量、照明和视觉舒适度方面的最佳选择。
