Abstract :

Background and Objective: Educational spaces in Iran, with a student population of about 12 million people and lowgradedness of 75% of schools in terms of energy management, are one of the most energy wasting applications. Adding to this is the developing student population and non-renewable energy reserves which are under distruction. Therefore, it is essential to bind to modern proposals for the use of renewable energy sources as alternatives for designing educational spaces in Iran to step towards further development of this application. In this study, in line with the introduction of green architecture as a renewable source of energy, the green schools model covered with a green roof in connection with atrium has been presented. Moreover, the impact of atrium-related green roof cooling and heating loads on energy management in pedagogical spaces in Sharekors as one of the cold climate regions of Iran has been investigated. Method: In the present study, which is descriptive-analytic, suggested a synthetic model of atrium- related green roof has been suggested as a strategy for energy saving in pedagogical. For studying the heating load in summer and cooling load in winter, three classrooms in Shahrekord as an example of cold climate region in Iran were simulated by Carrier Hap software (Hourly Analysis Program, one of the most modern softwares for heat transfer analysis whose results of are accepted by the U.S Green Building Council or LEED). Findings: The results of this project showed the advantage of using  green roofs for improvement of heating load in the winter and cooling load in summer in the classes with atrium-related green roofs  over the classes with 40-cm and 66-cm  conventional roofs .
