  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 .

  Energy saving is one of the challenges of today. In recent years, growing concerns about the environmental impacts of energy consumption and global warming has doubled the importance of this issue. Meanwhile energy consumption in construction sector is so high that saving even as little as possible in this section will have significant effect on efficiency rate of no renewable sources. Accurate measurement of thermal conductivity has an important role in determining the calculations of cooling and heating loads of buildings according to different climates. Considering multiple relevant parameters in energy consumption with no application of simulating tools cannot permit reasonable decisions on designing building parts. In this research, the annual energy consumption of an office building located in the climate of Yazd city has been simulated and compared by Design Builder. Manuscript profile
