Classify energy consumption for urban bldg.
Heating in Buildings in North of China
Energy consumption in buildings excluding heating
Ordinary Commercial Bldg.
Large-scale Commercial Bldg.
Relating to Manufacture Procedure
All Bldg. in China
Res. bldg. in rural area
70% is bio-energy
30% comm. energy
Civil bldg. in towns & cities
Residential building except heating
BEC in each sector
Building area in each sector
BEC accounts for 25.5% of Total social terminal energy consumption in China
Building energy data by per participant [kWh/(p.a)]
Building energy data by floor area [kWh/(m2.a)]
Data source: EIA 2005
35% of BEC
commercial energy 7.5~15kWh/m2.a
takes a great portion (no accurate data)
Terminal energy converted to electricity equivalent
Data source: 2005 Buildings Energy Data Book, U.S. Department of Energy
About ¼ of USA and 60% of Japan.
Heating Energy consumption comparison
Field investigated heating energy data in Beijing
Beijing VS. city of developed countries
Factors on Heating
Close window: 0.5～1/hr
Open window :3～10/hr
½ ~ 1/3
Therefore, heating energy consumption level in China is similar to developed countries.
