This work examines the solar performance of double-glazed windows in four offices in ACK buildings with and without solar window film in actual working conditions. Window films are passive thin films stick to the interior or exterior of windows to effect various solar-optical impacts including energy saving, UV reduction, and increased thermal comfort. For this study, the 3M Neutral 20 and 70 are selected which are made of multilayer nanofilms of 220 SAN25/THV 95-nm thick reflective layers. Real-time measurements of temperature, humidity, and luminous were conducted in 5 min intervals over the months of June, July, and August 2019 and data stored through WiFi system in iClouds. Arduino-type microprocessors and various temperature-humidity, and LUX sensors were assembled and programmed to transfer and store data in real time. Exploring and analyzing the data collected for four offices with and without window films in summer of Kuwait, it is evident that window film has good potential to save water by preserving interior humidity to the level of human comfort, decrease interior temperature to save energy and reduce CO₂ footprints, to restrict the solar UV rays to minimum level, and to reduce visual impacts of high solar luminous. The benefits and drawbacks of the selected window films are discussed here for the weather condition of Kuwait.

这项工作检查了ACK建筑物中四个办公室中带或不带太阳窗膜的双层玻璃在实际工作条件下的日光性能。窗户薄膜是无源薄膜，粘在窗户的内部或外部，可产生各种太阳光影响，包括节能，减少紫外线和提高热舒适性。在本研究中，选择了3M Neutral 20和70，它们由220个SAN25 / THV 95纳米厚的反射层组成的多层纳米膜制成。在2019年6月，7月和8月的每个月中，以5分钟为间隔进行温度，湿度和发光度的实时测量，并将数据通过WiFi系统存储在iClouds中。Arduino型微处理器和各种温度湿度以及LUX传感器均经过组装和编程，可以实时传输和存储数据。_2个脚印，将太阳紫外线限制在最小水平，并减少高太阳光的视觉影响。这里针对科威特的天气情况讨论了所选窗膜的优缺点。
