-The development of the Energy ADE v3.0 (led by TU Delft) started in spring 2024 within the European [DigiTwins4PEDs](https://digitwins4peds.eu/) project. The project is funded by the Federal Ministry for Economic Affairs and Climate Protection (BMWK) for the project DigiTwins4PEDs (case study: Stuttgart) as part of the [Driving Urban Transition - DUT](https://dutpartnership.eu/) partnership, which is co-financed by the European Commission (Funding Indicator:03EN3081A). The project is part of the DUT 2022 call which also contributes to the Urban Transition Mission of Mission Innovation as part of the MICall 2022 initiative.

--- This DDL script uninstalls the 3DCityDB schema for the Energy ADE. It must be run
--- from within the ADE Manager plugin of the 3DCityDB Importer/Exporter.

--- This script was first automatically generated using the 3DCityDB ADE Manager
--- and successively edited and restructured by:
