Dr. Hanieh Sanaeian, a faculty member at Iran University of Science and Technology, in an interview with the Permanent Secretariat of the International Conference on Energy Optimization in Buildings and Related Industries, discussed green schools. She noted that some schools are environmentally friendly and sustainable. Green schools are not only eco-compatible but also lead to significant energy cost savings. In addition to teaching standard curricula, these schools educate students on how to live in harmony with the environment, empowering them to steer the world toward a healthier, cleaner, and more sustainable future.

In line with this vision, Motahari Vocational School (Maryam Karimi), located in District 7 of Tehran, was selected as the first school under construction to optimize energy consumption and implement green school standards. The school, covering an area of approximately 2,213 square meters, includes a basement, ground floor, first floor, and second floor. It follows one of the most common architectural layouts used by the Tehran Provincial Administration for Renovation, Development, and Equipping of Schools for vocational schools. The project was assigned to Iran University of Science and Technology by the Tehran Administration for Renovation and Equipping of Schools, under the management of Engineer Mehdi Rahimi.

Regarding the project, Dr. Hanieh Sanaeian, the director of the Green School initiative, stated that the construction had reached the first-floor ceiling, with the second-floor columns undergoing concrete pouring. This makes it the first school under construction in Iran where green school policies have been implemented.

Since the second-floor ceiling had not yet been constructed, modifications and optimizations were still possible. Initially, the building was simulated without any changes, and energy consumption, daylight availability, and glare levels were calculated. Subsequently, optimizations were carried out in five phases:

1. Layout modification

2. Material adjustment

3. Window optimization

4. Shading design

5. HVAC system improvement

After implementing these optimizations, energy consumption was significantly reduced, dropping from 171 kWh/m² to 85 kWh/m².
