The consumption performance of 438 municipally owned buildings in 22 regions has been examined in the areas of water, electricity and gas. The average consumption during the three years under review (1401 to 1403) in the buildings under assessment is 741,055 cubic meters of water, 486,767,409 kilowatt hours of electricity and 11,197,405 cubic meters of gas. the average per capita changes in the three-year consumption of buildings in the city of Tehran during the current urban management period compared to the year before the announcement of the fourth four-year plan (1400) showed a 22.81% decrease in per capita water consumption, a 5.51% decrease in per capita electricity consumption, and a 10.65% decrease in per capita gas consumption, resulting in a total decrease of 7.36% in per capita energy consumption. With a reduction of 8,986,829 kWh of electricity in the buildings under assessment during the years 1401 to 1403 compared to 1400, energy consumption optimization at the Tehran municipality level resulted in a reduction of 6,829 tons of CO2 emissions and the cost reduction in 438 buildings under coverage during the three years under review in the electricity consumption section was equivalent to 7,234,938,325 Tomans. Also, calculating the energy label of buildings using the 14254 standard method and comparing it with the rank obtained in 1400 shows that based on the results, 94 percent of the buildings under assessment were awarded an energy label and only 6 percent of the buildings were not awarded a label.
