Question

geo-referenced energy database BIM-CityGML-ADE


HI EVERYONE. I AM LOOKING TO CONSTITUTE A GEOREFERENTIATED ENERGY DATABASE STARTING FROM REVIT. I AM NEW TO THE THEME, AND I HOPE YOU CAN HELP ME. IF I AM NOT WRONG, I have to CONVERT THE REVIT OR IFC FILE (VERY SIMPLE GEOMETRY) IN CITYGML AND THEN ADD ENERGY DATA WITH ADE? After this, on which tool can I see the mapped information? are there any tutorials to do it or some examples?

Thank you very much for your help

I don't know of any tutorials to do this but for viewing the result you might be able to use Cesium. FME has a Cesium Ion connector which I think is free for students to use. Cesium has a CityGML converter which can convert the CityGML into 3DTiles - I'm not sure if their CityGML converter supports the Energy ADE but its worth looking into.

 

 

If you need to have the CityGML data in a database then you are probably looking for the 3DCityDB - https://www.3dcitydb.org/3dcitydb/

 

 

I suggest you look at the FME Training to get a feel for FME and how to use it https://www.safe.com/training/recorded/. You will also need to look at how to create CityGML with FME which is a little complicated too. https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_ReadersWriters/citygml/Tutorial/writing_citygml_from_fme.htm And also here: https://knowledge.safe.com/articles/72453/creating-a-textured-citygml-model.html

 

 

Here is also some research which maybe you've seen already: https://repository.tudelft.nl/islandora/object/uuid:fb35db7c-9af8-488c-8d0b-263b138d8fd3/datastream/OBJ/download

 

 

Good luck

 

 

Hi @virtualcitymatt

thank you for your useful answer. Actually I'm still confused, maybe, If I explain better myself, you can help me again. The result I want to obtain is like this --> https://maptopixel.gitlab.io/3d/epc/

Using Celsium to create an energy database of a small neighbourhood starting from a Revit/BIM Model.

Now, I don't have clear the procedure to obtain this result, also I don't understand which format I have to use.

Do I have to transform Revit project into citygml or directly in 3Dtiles? Or directly Revit into 3DCityDB and not more?

 

Thank you
