Rates of mandatory energy-saving targets in new buildings
completed targets set by the State Council that “more than 90 % of new buildings
should be constructed under the mandatory standards for energy-saving”. This was
achieved thanks to stronger supervision and an increased implementation rate of
mandatory standards.
During the period of 11th FYP, there were 4.857 billion m
2
of new constructed
energy efficient building areas in China, accounting for 23.1 % of urban building
areas, which is continuing to increase. All or most of the new buildings in Beijing,
Tianjin, Hebei, Henan, Liaoning, Jilin, Heilongjiang and Qinghai municipalities,
provinces and regions, have been constructed following 65 % of the applicable
energy-saving standards.
3.2.1.2 Transformation of Heat Metering and Energy Saving for the
Northern Heating Area Shows Steady Progress
The Ministry of Construction and Ministry of Finance planned to renovate around
150 million square meters of existing residential buildings in the northern heating
area by flexibly assigning the tasks to different, according to local conditions. By
the end of 2010, 15 northern provinces and municipalities had finished renovating
182 million m
2
of their existing buildings and managed to raise their indoor
temperature by 3-6
C, sometimes by more than 10
C, saving one million tons
of coal every year and reducing the CO
2
emissions by 2.4 million tons. Meanwhile,
thermal comfort indoors was greatly improved in those areas.
On the other hand, some projects in Tianjin, Hebei, Shandong, Shanxi, and Inner
Mongolia began to practice the “charging by measurement” heating system
