Schools are the most suitable type of building for the application of indoor thermal comfort quality as they represent the main sector of the community. Thermal comfort plays a major factor in the educational building sector, especially in hot-arid climate. It has a big impact on building interior temperature as well as on energy consumption. The present study is an attempt to primarily introduce the existent indoor thermal comfort status as well as energy consumption in Egyptian public primary school building. To meet this objective, a methodological procedure has been followed. A field study is conducted
in a school building that are designed based on natural ventilation and air movement through ceiling fans to assess the indoor thermal conditions based on adaptive standard comfort (ASC) model during the students’ lesson hours during a three-day. In addition, electrical utility bills have been collected. Then, a dynamic building energy
simulation model carried out by using, DesignBuilder/EnergyPlus software for examining indoor comfort conditions as well as energy consumption of a typical school
building in Egypt. Findings revealed that lighting sources represent the largest proportion of energy consumption.
In terms of indoor thermal comfort, results indicate that a
higher level of thermal discomfort within the primary public school classrooms and the pupils stay more than 36.5% of their time daily in classrooms with thermal stress conditions.
