A kind of heavy construction energy consumption monitoring systemTechnical field
The utility model relates to a kind of energy consumption monitoring system, relates to a kind of heavy construction energy consumption monitoring system more specifically.
Background technology
Energy problem becomes the key factor of puzzlement social development and scientific-technical progress day by day, in China, only government offices' office building and large public building year power consumption just account for 22% of national cities and towns total power consumption, every square metre year power consumption be 10 ~ 20 times of ordinarily resident's house, be 1.5 ~ 2 times of the similar building of western developed country.According to International Energy Agency, Chinese Academy of Engineering, National Development and Reform Committee's energy research in one's power multiple research institution such as Tsing-Hua University to the prediction of China's future source of energy demand, China will more than 3,000,000,000 tons of standard coal equivalents in the year two thousand twenty energy demand total amount, wherein building energy consumption accounts for 1,000,000,000 tons of standard coal equivalents, will account for total energy consumption about 30%.And the energy utilization rate of China is only 1/2 of international most advanced level, Ministry of Construction's statistical figure display, nearly 2,000,000,000 square metres of China's annual town and country construction newly constructed house floor area of building, wherein more than 80% is high energy consumption building; Nearly 44,000,000,000 square metres of existing building, more than 95% is high energy consumption building.As can be seen here, the building energy consumption of China allows of no optimist, Energy Saving of Building under Heavy Responsibilities.
The large public building of different scales, the use energy feature of its whole year is different with energy resource consumption total amount, and the energy consumption monitoring to heavy construction, the mode also adopting manual entry to calculate again at present, waste a large amount of manpowers, and accuracy is not strong.
