The energy management system starts from the whole process of the system, follows the principles of system management, and establishes a complete, effective and documented energy management system within the organization through the implementation of a complete set of standards and specifications, focusing on the control of the establishment and implementation process. , to continuously optimize the activities, processes and elements of the organization, through routine energy-saving monitoring, energy audits, energy efficiency benchmarking, internal audits, organizational energy consumption measurement and testing, organizational energy balance statistics, management review, self-evaluation, energy-saving technical transformation , energy-saving assessment and other measures to continuously improve the effectiveness of continuous improvement of the energy management system, realize the energy management policy and commitment and achieve the expected energy consumption or use goals.

  GB/T 23331 "Energy Management System Requirements" The main contents of the standard are:

  1. General requirements: The organization should establish and implement an energy management system to reduce energy consumption and improve energy utilization efficiency. The energy management system should cover the organization's internal processes and outsourcing processes related to energy management.

  2. Management responsibilities: including management commitments, energy policies, roles, responsibilities and authority requirements.

  3. Planning: including energy factors, laws and regulations and other requirements, energy management benchmarks and benchmarks, energy goals and indicators, energy management plans and other requirements.

  4. Implementation and operation: including requirements for resources, capabilities, training and awareness, information exchange, document control, record control, operation control, etc.;

  5. Inspection and correction: including requirements for monitoring, measurement and evaluation, compliance evaluation, non-conformity, correction, corrective and preventive measures, internal audit, etc.;

  6. Management review: including requirements for general rules, review input, review output, etc.

   Background of GB/T 23331 "Requirements for Energy Management System"

  1. Macroeconomic pressures

Energy is an important material basis for national economic and social development. China's lack of resources and energy shortage have become an important factor restricting the sustainable development of the national economy. Due to the extensive economy at this stage, energy utilization efficiency is low and energy consumption is high, resulting in serious waste of energy. The phenomenon is very serious, and the shortage of energy has caused huge pressure on my country's lack of resources and environmental governance. The sharp decline in the world's available energy sources threatens the survival of human beings, and the international energy shortages threaten national security. Energy conservation and improvement of utilization efficiency are related to the sustainable development of the country.

   my country's per capita fresh water, oil, natural gas and coal possessions are far below the world average, and energy and water resources consumption is higher than the world level. China's energy consumption in 2007 was higher than the world average, accounting for 50% of the growth in global energy consumption. Energy consumption and water consumption per 10,000 yuan of GDP are higher than those of developed countries.

  Energy saving and emission reduction: The 1992 United Nations Framework Convention on Climate Change/1997 Kyoto Protocol has become a common measure to reduce emissions and protect the earth's homeland.

  The consumption of coal and fossil fuels not only pollutes the environment, but also induces problems such as the greenhouse effect, acid rain, diseases, and agricultural production reduction. Reducing energy consumption and improving energy efficiency can reduce emissions, reduce harm, and promote sustainable development.

  2009 Copenhagen World Climate Conference - China pledged to reduce carbon emissions by 40%--45% per unit of carbon emissions in 2020 compared to 2005, and it is imperative to save energy and reduce emissions.

  2. Experience in Micro Energy Management Practice

  Industrial energy saving mainly includes three ways: structural energy saving, technical energy saving and management energy saving. In energy management, it is gradually recognized that the development and application of energy-saving technologies and equipment is only one aspect of energy-saving work, and simply relying on energy-saving technologies cannot ultimately solve problems such as the contradiction between energy supply and demand. The key to energy management is to apply systematic management methods to reduce energy consumption, improve energy utilization efficiency, promote behavioral energy conservation, and build an energy management system. The characteristics and effects of energy conservation management include:

  Management energy saving with high input-output ratio

  Management energy saving is the support of technical energy saving and structural energy saving

   Low investment in energy conservation management, suitable for developing countries

  Managed energy saving can be widely applied at the enterprise level

  The application effect is good, such as Ireland's energy management system (MSE) saving energy consumption by 7%. In China, due to the relatively poor level of energy management at this stage, the proportion of energy saving through management is estimated to be as high as 10%.

In order to promote the formulation of international standards for energy management systems, the International Organization for Standardization (ISO) established ISO/PC242-Energy Management System Project Committee. work at the place. The committee held its first working meeting in September 2008 to draft the standard draft.
