Architectural Design of Future Sustainable Primary School in Iran Using Multi-Purpose Atrium

In this paper the role of Atrium in future primary school design in Tehran (IRAN) with regards to the environmental contribution has been demonstrated. A typical primary school in west of Tehran is selected for this investigation of thermal comfort and ventilation. Furthermore, in order to reduce the energy consumption, several proposals are carried out and the feasibilities are tested separately. The comparative result indicates that more access to the atrium space benefits the ventilation of the classrooms, intensifying the heat loss. Hence, controlling the size of opening area in atrium and seeking for the balance between ventilation and thermal comfort are essential in designing a sustainable school.
