Follow the Standards Te European standard EN 16001, passed in August 2009,
provides guidance for EnMS implementation. Te standard closely follows the ISO 14001 standard on environmental management. While a great number of German companies have already established an environmental management system in accordance with the ISO standard, an EnMS in accordance with the new European standard can be implemented inde- pendently or integrated into existing systems. Te European standard is primarily relevant for large
companies. However, EnMS establishment also makes good economic sense for smaller companies.
Screening: the Foundation of EnMS
An analysis of the current structure and scope of energy demand is the starting-point of every EnMS. Data from existing metering systems are a good starting point. Addi- tional temporary measurements also are useful. Te data obtained in these measures serve as the basis for the develop- ment of load profiles. Te results of this screening and the areas of potential energy savings must be documented in an energy report. Regular management reviews can show whether the defined targets have been achieved. Te installation of a system enabling comprehensive
monitoring of energy consumption is one of the key require- ments of the new European standard. Software-controlled collection and processing of individual energy-related data directly show the progress achieved and help identify further potential areas for savings. Such software systems provide synchronized recording and graphic plotting of energy demand and load profiles, including those of individual system components. Energy monitoring software also raises employee awareness for the most energy-efficient mode of operation of the system, and training courses can familiarize employees with new processes or EnMS application.
Sensible Investments Not all measures taken to improve energy efficiency make
good sense from both a technological and economic perspec- tive. Companies must make improvements to ensure sustain- able investment planning. Te pros and cons of the use of heat recovery systems, improved insulations, presence-controlled lighting, improved algorithms in electronic control systems and temporary shutdown of sub-systems must be consid- ered carefully in cost-benefit analyses. In these areas, minor improvements over time can add up to significant savings. Social responsibility also plays a role: if the European Union is to reach its goal of cutting carbon dioxide emissions by 20% by 2020, energy-intensive industries must do their part. ■
Energy-intensive German businesses should be working on their EnMS.
遵循标准
2009年8月通过的欧洲标准EN 16001为实施EnMS 提供了指导。在很多方面，该标准沿袭了ISO 14001环 境体系管理标准。大量德国企业已经按照ISO标准建立 了环境管理体系，因此，推进按照欧洲标准的EnMS可 以独立进行，也可以和现有的环境管理体系合并来做。 欧洲标准和耗能大的企业密切相关，包括铸造企业。 然而，对于小企业，建立EnMS也有很多经济上的好处。
数据筛选分析：建立EnMS体系的基础
实现EnMS的第一步就是要分析当前企业的能源需求 结构和范围。从现有测量系统得到的数据开始入手就很 好。附加的一些临时性的测量也有用。这些数据就是建 立负载的基础。一定要将数据筛选的结果和具有潜力的 节能领域记录到能源报告中。要定期进行管理工作总 结，检查是否实现了预期的目标。
欧洲新标准的一个主要要求是企业要安装具有全面监 控能源消耗的系统。各能源消耗相关数据通过软件的采 集和处理就可以直接显示节能的效果并可以找出下一个 有潜力的方面。这些软件系统可以提供同步的数据采集 和曲线显示能源消耗和负载情况的功能，包括那些独立 的部件。耗能监控软件也提高了员工的节能意识，以采 用最节能的方式操作。对员工进行培训使他们熟悉这些 新过程和EnMS体系。
可行的投资
并不是所有提供能源利用效率的措施都在技术和经 济两个方面同时取得好的效果。企业必须不断改进，保 证可持续的投资方案。采用余热回收系统，提高绝热、 有人才亮灯系统、电子控制系统的改进、子系统的临时 停机等的好处和坏处都要在成本和效益两个方面仔细进 行权衡。在这些方面，很小 改进，随着时间的推进也能 够产生显著的节能效果。同 时，社会责任也十分重要， 如果欧盟要实现将CO2排 放到2020年降低20%的目 标，耗能大的企业必须要做 出他们的努力。 ■
能源密集型的工作，德國企業應該 對他們 EnMS。
