Starting point
No widely applicable open model standard exists until now for Urban Energy Modelling
(like IFC or gbXML for buildings).
CityGML, open standard for exchanging 3D urban data,
doesn’t contain any energy-related objects or attributes.
CityGML is extensible through ADEs.
Urban energy tool developers (e.g. CitySim) have developed
their own tailor-made urban information.

Our Objectives
Store relevant energy-related data in a common open city data model,
used for energy simulations;
Offer data exchange and interoperability possibilities between urban
energy stakeholders (e.g. municipalities, ESCOs, etc.) and tools
…as well as with other expert fields (acoustics, statics). Combine data
collection effort!Energy ADE for CityGML

Conclusion and Outlook
CityGML Energy ADE extends an existing data exchange format to allow energy simulation on urban scale
Its development is collaborative and open process
Energy ADE is based on a modular structure and tackles different challenges
Outlook CityGML + Energy ADE has the potential to enable many further urban energy analyses
Impact of occupancy / behaviour
Energy epidemiology
Daylighting analysis
Impact of energy-efficient measures
Life cycle analysis etc…
We are very open to feedbacks and further active developers
