ABSTRACT
The building sector is one of the most important sources of CO2 emissions caused by human activities. It consumes nearly 40% of global raw materials and emits 40%–50% of all greenhouse gas emissions (Li et al., 2012). In China, the existing building area is about 45 billion m2, 95% of which is high-energy (Shang et al., 2012). Energy consumption control and low-carbon transformation of buildings are inevitable choices for Chinese construction industry. The effect of building low-carbonization depends on the application of low-carbon technologies. Low-carbon technology transfer plays a central role in mitigating carbon emissions and the international climate negotiations. Therefore low-carbon technologies in buildings are likely to make a tremendous leap in response to building efficiency improvement.
