 Chinese buildings rarely had thermal insulation and used twice as much energy to heat and cool as those in the Europe and the United States in similar climates.95% of new buildings did not meet China's own energy efficiency regulations.A 2011 report by a project facilitated by World Resources Institute stated that the 11th five-year plan (2005 to 2010), in response to worsening energy intensity in the 2002-2005 period, set a goal of a 20% improvement of energy intensity.
