GEG und DIN V 18599

GEG und DIN V 18599 (German Building Energy Act and DIN V 18599)

Please note: This publication is only available in German.

The 4th fully revised and expanded edition takes into account all of the changes that follow from the Gebäudeenergiegesetz 2024 (German Building Energy Act 2024) (GEG) and the pre-standard DIN V 18599:2018-09 for verification for residential buildings. Civil engineers, architects and specialist planners receive an introduction and a commentary on all the new developments. The fully calculated practical examples facilitate the implementation of the new legal regulations and normative provisions.

Basics, overview of changes and examples

The current version of the GEG from 2024 poses new challenges for those involved in building energy efficiency. Recognizing, accepting and dealing with them in the best possible way is the task of all those involved - this book is intended to provide support with that. It brings together expertise and useful information about the 2024 GEG in one clearly structured volume.

“GEG und DIN V 18599” helps you to fulfil the new requirements by providing the following bundled content:

• Basic knowledge
  What is the intention of the 2024 GEG? What is the background to the amendment and what can be derived from it for practical use? Who is affected? Are there any exceptions or options for adapting? The book answers these and similar questions in a well-founded and entertaining way.

• Amendments
  Of particular interest are the numerous changes resulting from the amendment of the law for those involved in building energy efficiency. The book sheds light on this and focuses in particular on the increased importance of DIN V 18599, which is now the sole basis for verification.

• Examples
  One chapter is dedicated to the complete calculation of an example in accordance with DIN V 18599 and explains the workings and methods through examples. For better comparability, the same example was chosen as in the previous edition – this makes it particularly easy to understand the changes made by the amendment to the law.

The book also contains a lot of other useful content, including a list of the standards and laws used and a table overview of the key requirements of 2024 GEG. Tables, diagrams and illustrations ensure a good overview and clarity with a wealth of information.
