Scenario Planning

Climate KIC Projects: Low Carbon City Lab (LoCaL)


Help cities access GHG data

Help finance & investors to find bankable cities‘ projects

Create tools for assessing greenhouse gas emissions, planning, investing and evaluating progress towards a low-carbon future

LoCaL supports cities to unlock their potentials

Low Carbon City Lab (LoCaL)


LoCaL Ecosystem


3DGPC


One project within LoCaL platform

Energy scenario planning and CO2 reporting based on 3D city model + real estate data (energy source + thermal characteristic) • Based on 3DCityDB

Create basis for reliable MRV system as central information hub and data integrator

Architecture


Energy ADE?

Energy ADE + 3D GPC = ?


Question?

Can we make use of the Energy ADE in 3DGPC project?

Is the Energy ADE suitable for our applications?

Possible Steps:

Implement Energy ADE into 3DCityDB

Map and integrate available data to Energy ADE

Base further calculations and report generation on Energy ADE

Possibility to integrate further data sources!

CityGML data management solution

• CityGML 2.0 compliant relational schema for 3D city models

• Realized on top of established spatial database systems (PostgreSQL/PostGIS, Oracle)

• Oracle Spatial Excellence Award 2012

Efficient database tools

• Loading/extracting massive CityGML-based 3D city models

• Export of KML/COLLADA/glTF visualization models

Open Source project under LGPL 3.0

3D City Database


CityGML, 3D City Database and tools


In production use in many cities worldwide

• Berlin, Hamburg, Munich, Dresden, Potsdam, Nuremberg

• London, Rotterdam, Den Haag, Helsinki, Finish Land Survey, Vienna, Salzburg, Zurich

• Singapore

Germany

• Nation-wide CityGML model containing buildings in LOD1 and LOD2 (ongoing)

• Currently more than 50 Mio. buildings in one 3DCityDB instance

Research & Development

• TU Delft, TU Munich, TU Berlin, Karlsruhe Institute of Technology, Eifer, EDF

• …

3DCityDB + Energy ADE


How to implement the Energy ADE in the 3DCityDB?

Create database schema for Energy ADE (Oracle + PostGIS) TUM is working on the automatic creation of a database schema for an ADE

We are planning to use their tool

RWTH Aachen?

Enable the Importer/Exporter to handle Energy ADE Extent the existing Importer/Exporter

Challenges


Energy ADE comprises many classes

Our idea was to start implementing a ‘core’/subset of the ADE

Is it possible to define a core?

• How can we define such a core?

• E.g. omit some classes for the first implementation?

How to deal with concepts making problems in RDBMS?

• Multiplicities of attributes (arrays)?

Money?

Open Questions


Is someone doing similar things?

Does some have experience with this?

Is it possible to define a core of the ADE?

Can we define a project (ZIM, Climate KIC…) to get budget/funding?

Does someone want to participate? Can we built a consortium?
