1.背景信息 Background

統(tǒng)計顯示，我國建筑能耗約占全國總能耗的28%，在我國每年新建的20億平方米建筑中，其中99%是高能耗建筑；而既有的建筑中，僅有4%采取了節(jié)能措施，具有巨大的節(jié)能空間，能耗監(jiān)測系統(tǒng)推廣已經(jīng)勢在必行。節(jié)能降耗，計量先行。

Statistics show that building energy consumption accounts for about 28% of the country’s total energy consumption. Among the 2 billion square meters of buildings newly built in our country each year, 99% are high-energy buildings; and only 4% of the existing buildings use Energy-saving measures, so there is still a huge energy-saving space, the promotion of energy consumption monitoring system is imperative. Energy saving and consumption reduction, measurement first.
