Analysis on Energy Efficiency and Consumption of Existing Residential Buildings in Shijiazhuang

Abstract:

Through the investigations on a total of 2,079 residential buildings in Shijiazhuang, the author got the distributions, ages, structures, heating and cooling patterns, indoor comfort conditions, state of energy efficiency and actual energy consumptions etc. In addition, non-energy-efficient buildings, energy-saving 30%, energy-saving 50% and energy-saving 65% accounted for 24.8%, 17.8%, 22.4% and 35.0% respectively. The author calculated the total energy consumption of 397 sample existing residential buildings which is equivalent to about 48,600 t Standard Coal, and average energy consumption per unit area was about 28.0 kg/m². The results may contribute to the future work of energy efficiency renovation of existing residential buildings in Shijiazhuang, even the whole Hebei Province.
