Our total energy consumption ranks second in the world, with an average energy level of the total population is less than 50% of the world average, the total building energy consumption increased year by year, 9 percent more than a high-energy buildings, has accounted for the total energy consumption 27.45%, building energy consumption is three times more than in Western countries, in building energy consumption, nearly 55% of heating and air conditioning energy consumption, and is still rising. Heating industry is the status quo: 2010 total consumption value of the heating industry accounted for 15% GDP of about 1.2 trillion yuan. The country is about 1/4 of coal for heating. Coal-fired heating, especially small household boilers, most of the vertical type, the exhaust gas is not any treatment, resulting in the generation of thousands of tons of dust pollution, the sky and the earth the majority of the northern region a "pitch-dark" year. Currently, businesses are vigorously carry out energy conservation work. In many industries already nothing will compete, such as reducing the computer's idle time, energy saving, the use of the charger. However, the issue of energy saving heating energy-hungry world, are less concerned. China must reverse the traditional high energy consumption, high pollution, high waste of heating centralized heating supply system is a typical big pot, according to the area to pay heating costs, there is widespread waste, open hot, open windows and heating are common occurrences. More than 70% of residential central heating system is a tandem structure, the whole building to open fully open to fully closed off, this does not close the structural disadvantages of single household heating, can not restrict individual malicious users refused to pay heating costs. According to the survey, individual cells or even 40% of users do not pay heating costs for many years, but still enjoy the heating supply. If the household smart metering independent heating, steam heat measurement is extremely difficult and complex systems, into a larger, difficult short-term promotion. Even new homes are only part of the use of smart metering independent heating.
