Chinese Green Building Label (GBL)
Green building refers to a structure and using process that
economizes resources (efficiently using energy, land, water, and
materials), protects environment and reduces pollution to the utmost
throughout a building’s life-cycle; provides healthy, applicable and
productivity-improving space; and harmoniously coexists with
nature.

Why do we set Design Label?
1. Green Building Label requires a relatively long phase;
2. Real estate developers’ passion may reduce after 1 year of operation, as
buildings being sold;
3. The effect of government to promote green building can not appear in time.
Range of Evaluation
New construction, expansion and alteration of residential buildings
and public buildings (as well as ultrahigh-rise public buildings),
including office, shop, hotel buildings and industrial buildings.

According to the climate divisions, China has five climate types, respectively as
tropical monsoon climate, subtropical monsoon climate, monsoon climate of medium
latitudes, temperate continental climate, plateau (mountain) climate and thus there are
five types of building thermal divisions. As the geography and weather are in great
difference from north to south and from east to west, green building construction
technologies in different places are with different emphasis.

their low incremental cost and significant
improvement effect on the site environment.
2 Overview of Chinese Green Building Label Evaluation
Introduction of key technology –green construction and
materials-saving
The acceptance work, system debugging and green operating after
construction will be the key issues faced by the green building in China.
Stage 1
• Develop the construction organization and design program and make the budget statement before construction.
Stage 2
• Strictly operate accordance with the requirements of green construction during construction process.
Stage 3
• Organize and record the pictures and daily records after construction is completed.
• Collate the materials balance ticket, construction budget statement, the calculation sheet of the recyclable materials utilization ratio of the building projects.
2 Overview of Chinese Green Building Label Evaluation
Through the analysis of different star green building project, the effect is as follows:
Community greening rate reaches to 38%;
Average energy saving rate is 58%;
Water-saving rate is 15.2%;
Recyclable materials rate is 7.7%.
Through the development of green buildings, we not only achieve the overall goal of
building energy-saving (1 billion tons of coal equivalent) but also reduce industrial
energy consumption by material savings.
It is predicted there are 300 new green buildings in China each year, it will realize
the achievements of saving energy 25.5 billion kWh (equivalent to 876,000 tons of
coal) reducing emissions of CO2 2.298 million ton, saving water resources 90 million
ton, 330 million ton of recyclable materials during the 12th “Five-Year" period.

2 Overview of Chinese Green Building Label Evaluation
The incremental cost of green building
Note: data form China GBC
The data above is the incremental costs statistical data of the green building before 2012, presenting a downward
trend with the gradually mature green technology and the increasing green products.
Different technical routes might cause big difference among the increment cost of green buildings at the same
evaluation level, and the achievement of high level stars is not necessarily with high cost. For some green
buildings, non-economic and non-low carbon phenomenon comes into being due to excessive “greening” caused
by undue use of green construction technologies.
The increment costs of green buildings in different places are different due to the climate and other features. In
some places, the building energy efficiency is set up high, and thus the increment cost of green buildings is
relatively low. For example, the increment cost of three-star green buildings in Jiangsu Province is about RMB
60/m2 for residential buildings and 200/m2 for public buildings.

3 Updates of Green Building Evaluation Standards in China
Support from the government
The developing direction of green building
State Council
The State Council issued the Integrated Work Program of “12th five-year” Energy-
saving and Emission Reduction, which clearly states that to develop green building is
the key task of the energy-saving and emission reduction, including:
(1)To continue to improve the green building standard system, and encourage the
local governments to develop the stricter standard of green building;
(2)To enhance the implementation of green building assessment label;
(3)To carry out the relevant demonstrations of green building.
MOHURD and NDRC
Ministry of Housing and Urban-Rural Development (MOHURD ) and The National
Development and Reform Commission (NDRC) have developed the Green Building
Action Program, which put forward the concept, goal, basis principles of promoting
the green building development, and clearly defines the key tasks and guarantee
measures.
4 Green Building Policy Guidance in China
MOF and MOHURD
Ministry of Finance and MOHURD have jointly issued The Comments on the Implementation
for Promoting the Green Building Development in May, 2012, which draws up requirements
on green building increment and announces national allowance standard for green building
for the first time.
To improve the proportion of the green building in new building. In 2020 the green
building will account for more than 30% of the new building, and the energy and
resource consumption level during the construct and use process of the building will
close to or reach to the present level of that in the developed countries.
Public housing invested by government must fully implement green building standard,
and the newly increased green building area are expected to reach to above 1 billion m2
in 2015.
Reward the green building above 2-star level. The award standard in 2012 is:
45 Yuan/ m2 for 2-star level green building,
80 Yuan/ m2 for 3-star level green building (the award amount accounts for nearly 50% of the incremental
cost of the residential building).
To support the mass development of the green building. The green ecological city whose
new buildings fully reach to or above the standard of 1-star level could get 50 million
Yuan from central government.
