| Summary/Abstract |
In order to promote energy efficiency and emission reduction, the importance of improving building energy efficiency received sufficient attention from Chinese Government. The heat metering and energy efficiency retrofit for existing residential buildings of 0.15 billion m2 in northern heating regions of China was initiated in 2007 and completed successfully at the end of 2010. This article introduced the background and outline of the retrofit project during the period of 11th five-year plan. Numerous achievements that received by retrofit such as environmental protection effect, improvement of indoor environment, improvement of heating system, investment guidance effect, promotion of relevant industries and increasing chances of employment were concluded. Valuable experience that acquired from the retrofit project during the period of 11th five-year plan was also summarized in this article. By analyzing the main problems emerged in the past, pertinent suggestions were put forward to promote a larger scale and more efficient retrofit project in the period of 12th five-year plan.

| Summary/Abstract |
In China, the area of existing buildings in urban and rural has exceeded 43 billion m2 at present and more than 90% of them are high energy consumption buildings, which have poor thermal insulation performance, low energy efficiency technologies and equipments, and severe energy waste in HVAC system. Carbon trading in construction field not only promotes energy efficiency retrofit of existing buildings and energy-saving technologies, but also reduces the financial pressure of government. The most important technical issue is how to estimate the carbon trading volume reasonably. Based on the requirements of energy efficiency retrofit of existing buildings, relevant national or professional standard standards and CDM small scale project methodologies, this paper puts forward a simplified and practical method of checking and certifying the carbon trading volume of existing buildings retrofits in China and calculates four typical cases for trail. Moreover, a comprehensive methodological framework is presented to make the method guide actual cases more directly and apparently. The framework comprises project analysis, scenario determination, data collection and envelope calculation.
