Overall, the activity seeks to instill the principles of environmental sustainability in students and develop their creative abilities to design environmentally friendly architectural models. It aims to enhance their environmental awareness and encourage them to present sustainable architectural ideas and projects that contribute to achieving the Sustainable Development Goals and building a more sustainable future for generations to come.
