This is a 3DCityDB extension for the Energy Application Domain Extension (Energy ADE) for CityGML. The Energy ADE extends CityGML by features and properties necessary to perform energy simulations and to store and exchange the corresponding results.
ℹ️ The Energy ADE extension is in maintenance mode with no significant active development planned. Existing bugs will be fixed, but large new features will likely not be added. Support through contributions or funding is welcome.
This extension adds support for managing Energy ADE data inside the 3DCityDB and enables the Importer/Exporter tool to load and export Energy ADE enriched datasets. The support is tailored to the Karlsruhe Institute of Technology (KIT) profile of the Energy ADE version 1.0.

- Where to file issues: https://github.com/3dcitydb/energy-ade-citydb/issues
The Energy ADE extension consists of two main parts:
- A relational schema mapping the KIT profile of the Energy ADE data model to a set of database tables and objects. The relational schema is built upon and seamlessly integrates with the official 3DCityDB relational schema.
- Java modules that are automatically loaded by the Importer/Exporter and enable the tool to read/write Energy ADE enriched datasets and to store and manage Energy ADE data in the 3DCityDB.
Before using the Energy ADE extension, you must set up an instance of the 3DCityDB and install the Importer/Exporter tool. Please follow the installation guidelines provided in the 3DCityDB online documentation. You will need the ADE Manager Plugin of the Importer/Exporter. So, make sure to select this plugin in the setup wizard of the Importer/Exporter.
Afterwards, download a release package of the Energy ADE extension as ZIP file from the
releases section. Please check the release information to
make sure that the extension can be used with your version of the 3DCityDB and of the Importer/Exporter tool.
Unzip the package into the ade-extensions folder inside the installation directory of the Importer/Exporter.
Next, create and register the Energy ADE relational schema in your 3DCityDB instance. The easiest way to do this is to use the ADE Manager Plugin and the contents of the unzipped release package. Follow the steps described in the 3DCityDB online documentation:
You have to register the schema only once in every 3DCityDB instance that should be able to manage Energy ADE data.
Finally, use the Importer/Exporter to connect to your Energy ADE extended 3DCityDB instance and load/extract energy data.
If you have correctly unzipped the Energy ADE extension package inside the ade-extensions folder, the tool will
automatically detect the extension and will be able to handle Energy ADE datasets. Again, the main steps for using an
ADE extension with the Importer/Exporter are described in the 3DCityDB online documentation:
Simple datasets for testing the Energy ADE extension can be found in the resources/datasets folder of this repository.
The relational schema for the Energy ADE has been fully automatically derived from the XML schemas using the ADE Manager Plugin of the Importer/Exporter. This ADE-to-3DCityDB mapping should work for all CityGML ADE XML schemas and is documented here.
The Java module for enabling the Importer/Exporter tool to store Energy ADE data according to the extended relational schema
has been manually implemented against the ADEExtension interface and plugin mechanism of the Importer/Exporter.
The ADEExtension interface has been introduced with version 4.0
of the 3D City Database. The TestADE repository demonstrates the
implementation of an artificial ADE and may serve as template for implementing extensions for your own ADEs.
The Java module for parsing and writing Energy ADE enriched datasets is implemented as extension for the open source CityGML library citygml4j. More information can be found here.
The Energy ADE 3DCityDB extension uses Gradle as build system. To build the extension from source, clone the repository to your local machine and run the following command from the root of the repository.
> gradlew installDist
The script automatically downloads all required dependencies for building the module. So make sure you are connected to the internet. The build process runs on all major operating systems and only requires a Java 8 JDK or higher to run.
If the build was successful, you will find the extension package of the Energy ADE module under energy-ade-citydb/build/install.
This extension was initially developed and brought to the 3DCityDB open source project by Virtual City Systems and the Institute for Automation and Applied Informatics (IAI) at Karlsruhe Institute of Technology (KIT).
The Energy ADE is an Application Domain Extension for OGC CityGML 2.0.
