Description

Energy management method and device for film production process {METHOD AND APPARATUS FOR MANAGING ENERGY OF FILM PRODUCTION PROCESS}

The present invention relates to a method and apparatus for managing energy used in a film production process.

Energy such as electricity and gas is indispensable to maintain various devices in the modern society, and a large amount of energy is used for the continuation of the modern society. However, since energy is also a limited resource, the energy shortage problem is intensifying, and accordingly, interest in a method of efficiently using energy in consideration of environmental factors and economic factors is increasing.

Meanwhile, industrial energy consumption exceeds about 60% of total energy consumption. Accordingly, in order to efficiently use energy, there is an increasing need to firstly manage industrial energy. For efficient management of industrial energy, each factory is developing a plan to manage the energy of the factory. However, up to now, rather than considering the consumption of energy itself, the situation is merely replacing existing facilities with energy-efficient facilities or performing management for energy saving depending on the subjective experience of engineers.
