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.

The present study is an attempt to primarily examine thermal performance of public primary school in Assiut city, Upper Egypt (hot arid climate) targeting to identify how much time pupils achieve thermal comfort conditions in their classrooms. In order to achieve this aim the current status of a typical public primary school is investigated through field measurements in terms of thermal comfort indices. These thermal comfort indices are the Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfied people (PPD). The results show that for the recent school building design there is strong relation between indoor comfort conditions and outdoor temperature. In addition to the average measured values of both the PMV and PPD inside the classrooms were 1.17 and 38.86%; respectively. Clearly, these results indicate that a higher level of thermal discomfort is existing within the primary public school classrooms as the pupils spent more than 36.5% of their time inside the classrooms under thermal stress conditions.
