Laws and Regulations

The Energy Efficiency Act (EnEfG) marks an important step towards increasing energy efficiency and utilizing previously untapped energy sources in Germany. It promotes the use of industrial waste heat to enhance energy efficiency and protect the environment in Germany by requiring high-energy-consuming companies to implement measures to recover and reuse waste heat. The exact legal regulations are designed to realize energy savings that contribute to the reduction of primary and final energy consumption. With our free guide and Excel template for the Energy Efficiency Act (EnEfG), energy efficiency measures can be identified that generate less waste heat.


The Energy Efficiency Act (EnEfG) requires, according to §16, that companies avoid waste heat whenever possible and minimize the production of technically unavoidable waste heat, while taking the state of the art into account. The utilization of waste heat helps companies reduce energy costs by requiring less external energy for heat generation. Additionally, their ecological footprint improves through the reduction of CO2 emissions, which can contribute to meeting environmental requirements. To help you achieve these benefits, we provide a free guide and an Excel template for the Energy Efficiency Act (EnEfG).

These tools provide valuable assistance for the correct implementation of the Energy Efficiency Act in daily business operations and offer answers to frequently asked questions. A forward-looking perspective on developments in energy efficiency and the related legal framework rounds off the offer.


Energy Efficiency Act (EnEfG): The Key Points at a Glance

  • The Energy Efficiency Act aims to reduce energy consumption in Germany.

  • Practical tools, such as a free guide and an Excel template, simplify the implementation of the EnEfG.

  • The provided resources support companies in effectively and economically meeting legal requirements.


Fundamentals of the Energy Efficiency Act and Free EnEfG Guide Download

The Energy Efficiency Act (EnEfG) is a central part of efforts to increase energy efficiency in Germany. One step towards implementing the requirements of the Act is to provide companies and institutions with the necessary tools and information to ensure compliance. Therefore, we offer a free guide and an Excel template for the Energy Efficiency Act (EnEfG).


Goals and Relevance of EnEfG

The EnEfG sets clear energy efficiency goals. It aims to improve the efficiency of energy use in companies and public institutions, thereby making a significant contribution to climate protection. This concerns both the federal government and the states, which are all required to continuously increase their energy efficiency.

On the corporate side, the implementation of technologies under the EnEfG for utilizing waste heat can significantly reduce their energy consumption while also making a substantial contribution to environmental protection. Such technologies capture the waste heat generated during production processes and return it to the energy cycle of the operation. This not only has ecological advantages by reducing greenhouse gas emissions but also provides economic benefits through lower energy costs.

Companies with an average annual total final energy consumption of 2.5 GWh or less (within the last three completed calendar years) are exempt from the obligation under §16 Abs. 4 of the Energy Efficiency Act (EnEfG). The free guide also provides detailed information on deadlines for companies with total final energy consumption over 2.5 GWh and over 7.5 GWh.


Legal Framework

The legal framework of the EnEfG involves extensive regulations that oblige companies to comply with efficiency standards and carry out regular energy audits. This framework is crucial for the national implementation of international agreements on energy efficiency and is described in more detail in the free guide.


EnEfG as the Successor to the Energy Services Act

The Energy Services Act (EDL-G), which previously defined measures to improve energy efficiency, is replaced by the EnEfG. This enables an improved and expanded legislative structure to meet increasing demands for energy efficiency. The provided guide explains the differences to the previous law and provides a comprehensive overview of the innovations brought by the EnEfG.

For more detailed information on the fundamentals of the Energy Efficiency Act and practical assistance in implementation, the Energy Efficiency Act (EnEfG) guide and an Excel template are available for free.

Requirements, Measures, and Implementation with Our Free Energy Efficiency Act (EnEfG) Excel Template

The path to compliance with the Energy Efficiency Act (EnEfG) and the realization of energy savings are facilitated by a practical Excel template. This supports companies in recording and analyzing their energy data and in planning and implementing efficiency measures.


Conducting Energy Audits According to the Guide

According to the EnEfG, legal entities must conduct energy audits or establish an energy management system. These audits are not only mandatory but also provide a detailed overview of consumption patterns and help prioritize the most efficient measures.


Implementation of Energy Management Systems

Companies benefit from establishing energy management systems by achieving continuous improvements in energy performance. This includes structures for managing and monitoring measures, including the utilization of waste heat and other energy-saving measures. These structures are essential for operators and companies that want to systematically improve their energy efficiency and thus meet the requirements of lawmakers.


Financial Incentives and Obligations for Companies and Operators

The EnEfG provides both incentives and fines for companies that do not comply with legal requirements. By using our template, companies can ensure that they pursue both the financial benefits and the obligations and plan appropriate measures. This also includes preparing for audits and demonstrating efficient energy use to avoid fines.


Assessment of Economic Feasibility Based on DIN EN 17463

The EnEfG establishes the DIN EN 17463 as the method for the assessment of economic feasibility of energy efficiency measures. By applying this method and utilizing the net present value method, companies can determine the financial benefits of these measures. In this context, the EnEfG Excel template serves as an essential tool to efficiently develop implementation plans. Any measures that are economically feasible according to DIN EN 17463 must be included in and published as an implementation plan.


Assessment of Economic Feasibility Thanks to the EnEfG Excel Template

The evaluation method according to the DIN EN 17463 (VALERI) allows for checking the economic viability of investments in energy efficiency. Using the Excel template, companies can accurately capture the necessary data and calculate the net present value. This serves not only to comply with legal frameworks but also emphasizes potential financial incentives through energy savings and government subsidies.


Consultation and Certification

A solid understanding of the DIN EN 17463 is crucial for properly assessing economic feasibility. To facilitate this, the Excel template for EnEfG provides structured guidance. Furthermore, it is advisable to utilize professional tools and support, such as energy auditors and software tools like the Climate Control Center from Global Changer.


Future Development and Outlook

The future of energy efficiency in Germany will be shaped by the Energy Efficiency Act (EnEfG). It provides a strategic framework to sustainably reduce total energy consumption and makes a significant contribution to achieving climate neutrality.


Amendment of the Law

The focus of the amendment of the EnEfG is on adapting to changed conditions due to climate change and integrating European law. The amendment of the Energy Services Act aims to enhance the effectiveness of the EnEfG. A stronger focus on renewable energies and a reduction in primary energy consumption is expected. In the guide, you will also learn about a planned amendment to the deadlines.
