Educational buildings play a significant role and have a considerable impact on cities. Research indicates that a substantial portion of non-industrial energy consumption occurs in these educational structures. On the other hand, students, as the primary users of educational buildings, should experience optimal thermal comfort to achieve the best performance and efficiency. Extensive research has been conducted in this field, but this article introduces a novel approach using nanotechnology and various techniques to enhance the properties and components of buildings. The goal is to reduce energy consumption and improve thermal comfort. Specifically, we eva‎luate thermal comfort and energy consumption in an educational building (a school) using Aeropan and nano-PCM in the walls and window glasses, respectively. This article presents a simulation and experimental analysis of thermal comfort (PMV) and energy consumption for three layouts of the educational building: Linear-shape (LS), Integrated Linear-shape (ILS), and U-shaped (US). The simulation is performed using EnergyPlus 9.6 software, while empirical data is collected using the TESTO 425 device. The case study in this research focuses on a 12-class elementary school located in the Farhanhshahr area of Shiraz, Iran. The results of this study demonstrate that after implementing nano-PCM and Aeropan techniques in window glasses and walls, the US layout exhibits the highest reduction in energy consumption compared to LS and ILS layouts. This reduction amounts to 12.03% on the coldest day of the year, 11.66% on the hottest day, and an average monthly reduction of 11.80%. Additionally, this layout, utilizing nanomaterials, provides greater thermal comfort than the other two layouts during the coldest, hottest, and average monthly conditions, resulting in an overall improvement.
