Investigating The Role of Green Roof in Reducing Energy Consumption of Educational Buildings (Case Study: Hagh Panah Primary School for Girls in Isfahan City)

One of the concerns in the current world is the depletion of non-renewable energies reserves. In the urban space, the factor affecting such energies are educational buildings with high energy consumption. Green roof system is a suitable solution to improve energy consumption in these buildings. This research aims to optimize energy consumption in educational buildings and with descriptive-analytical research method, has addressed the issue of green roof system with Minimum load on the roof structure and its impact on energy consumption of these buildings. Also, a sample of primary school in Isfahan city with a simple roof was simulated in terms of energy consumption by Design builder software. After that, this primary school was simulated again with all main information about green roof system. Finally, the results show that green roof system with grass vegetation that has shallow depth of root and growing medium, has caused a minimum load on the roof structure and optimized energy consumption of cooling and heating systems of this educational building and reduced the total energy consumption of this building by 4.8% during one year
