Appalling Waste of Energy in Buildings

Buildings account for a significant share of energy waste (almost 50%) in Iran including households, commercial sectors, private companies and state organizations. 
Close to 2.4% of the world's energy, equal to the energy produced by burning 3.6 million barrels of oil per day, is produced in Iran and 1.8% of the total energy is consumed.
Iran is among the most energy inefficient countries, with energy intensity three times higher than the global average and 2.5 times the Middle East average. Following countries like Russia and Saudi Arabia with energy intensity indices at 0.53% and 0.5% respectively, Iran is ranked third with 0.63%.
Energy intensity is a measure of energy efficiency calculated as units of energy per unit of gross domestic product. High energy intensity indicates a high price or cost of converting energy into GDP and vice versa.
