Energy-Efficiency in Educational Buildings in Iran: Analysis And Measures

Worldwide energy demand for the building sector is predicted to grow by more than 50% from 2010 to 2050. The share of energy usage in building sector in Iran is 2 to 3 times higher than the world average which is 31%. In this study, the building energy performance of nine typical public schools in three cities of Iran including Ilam, Tabriz, and Yazd has been simulated. The goal of this research project is to investigate the energy performance of the schools building by evaluating their envelopes through different scenarios. The results represented that the natural gas usage for heating has been reduced in all scenarios except for adding overhangs on windows. The most reduction was in Yazd for the new walls followed by roofs and windows by 42%, 33% and 8% respectively. The final results of implementing all scenarios indicated a significant decrease of natural gas usage by 79% in Ilam, 74% in Yazd and 63% in Tabriz.
