Energy audit refers to energy accounting systems, systems for evaluating rational use of energy, and energy status review mechanisms, which scientifically and normatively provide a quantitative analysis on the status of enterprise energy use, comprehensively evaluation of industry energy efficiency and energy consumption level, and analysis of energy-saving potential and opportunities.

Energy Audit is a kind of audit and evaluation method for the energy consumption level of industrial enterprises and service industries, the cost analysis of energy use expenses, the energy efficiency of the equipment, the energy saving approval of the energy-saving renovation projects that have been implemented, and the intelligent energy use management level of the enterprises. Through the Energy Audit, the improvement suggestions for unreasonable energy costs, proposes replacement plans for high energy consumption equipment with low energy efficiency, proposes solutions for intelligent energy use management of enterprises, and proposes solutions for the use of new energy in enterprises. But none of this is mandatory.

We also work on energy saving diagnosis and energy usage status assessment. Different from cleaner production audit and energy audit, energy-saving diagnosis and energy use status assessment will investigate, test and calculate the energy consumption status of energy using units or equipment, identify the unreasonable links and causes of energy use, and propose ways to improve countermeasures. Reducing energy use costs, reducing the use of fossil fuels, improving the level of enterprise energy use management, the use of new energy, and the construction of enterprise energy management system are the main purposes of the enterprise   to carry out energy conservation diagnosis. Cooperating with Beijing Dongcheng District Education Commission and Haidian District Education Commission, we have carried out energy use assessment and energy-saving diagnosis for some primary and secondary school communities. At the same time, we also conducted related assessment business for Tangshan Lunan Service Company in Hebei Province and Henan Foreign Trade School.
