Our country has both the energy saving renovation can save 750000 tons coal equivalent a year and 2 million tons of CO2 emissions reduction, about 2 billion m2 building area of new building each year and this process will last 25 to 30 years. According to estimating preliminarily, civil public buildings with high energy consumption can save 45800 tons a year Coal equivalent through energy saving transformation [8]. A residential program, for example, only solar vacuum tube central heating systems can meet the resident's bath need, at the same time, save 375000 degrees power every year, equal to 327000 tons of CO2 emissions.
