Exploring the influences of green industrial building on the energy consumption of industrial enterprises: A case study of Chinese cigarette manufactures

As one of the three major fields of energy consumption, industrial enterprises are under pressure regarding energy saving and emission reduction, and industrial building energy consumption takes up more than 50% of the total consumption. Therefore, it is essential for industrial enterprises to develop green industrial buildings to achieve targets for reducing CO2 emissions. This study compared the standard evaluation characteristics for green industrial buildings domestically and abroad. Also, eQUEST and the scenario analysis were adopted to simulate and calculate the energy consumption, energy saving potential, and the energy consumption structure applied to 11 green industrial building projects in Chinese cigarette manufactures. Then, the simulated data and the measured data of the operating projects were compared, and a comprehensive and systematic evaluation was worked out for them. Finally, the problems existing in the operation of the green workshop in cigarette industry enterprises are found out, and the corresponding improvement measures were put forward. Results showed that the application of energy-saving technologies relates to the location, energy-saving targets, and energy-saving efficiency; the higher proportion of the energy consumption for a specific system, the greater potentials of systematic energy saving; Enterprises have all reached the pre-set energy saving targets after the implementation of green workshop projects; The unit comprehensive energy consumption intensity for the most sample enterprises achieve the standard requirements after the technology improvement.
