Research on calculation method of energy conservation amount in energy management contract

Describes a method based on artificial neural networks (ANN) to calculate the energy conservation amount in energy management contract(EMC). By analysing the major influencing factors of energy consumption of public buildings and establishing the calculation model of actual energy consumption with ANN, simulates the annual consumption. The energy conservation amounts are equal to the margin between the simulated energy consumption value and the actual value after reformed. The simulation of the energy consumption of two public buildings in 2007, in Nanjing, shows that the deviation between the annual simulated value and the actual value is within 3%.
