Add attributes to Cesium OSM Buildings locally

My research focuses on large scale building energy modeling. I would like to add energy modeling attributes Cesium OSM buildings layer to be able energy data to buildings at any location (assuming the location has buildings in the OSM layer). I would also like to do this on my local machine, outside of ion. Is that possible?

I currently create the visualization locally by spatially joining our building data (metadata, savings) to a shapefile of the buildings for the research. FME workbench is used to convert the shapefile into Cesium 3D Tiles and use CesiumJS for the visualization (locally). Example image below/attached.

This [topic] posed a similar question

Is this possible? Does anyone have any recommendations or is it not possible to edit or add metadata to the features (buildings) of the OSM layer?

Welcome to the Cesium community!

If I understand correctly, you would like to edit the metadata of Cesium OSM Buildings. In that case, you can reference Omar’s response in this post as a starting point.
