What is UBUBI?

The UBUBI project was initiated as a collaborative research project between several Canadian universities and companies. The focus of this research is to enable LCA analysis early during the building design process. Other software is available to perform an LCA analysis but none of them focus on the non-expert users enabling them to easily do an LCA analysis with less details in their building model.

What UBUBI stand for?

The name "UBUBI" stand for "Uncertain But Useful Building Information".

Fun fact

In the Zulu language, UBUBI means: fighting evil(s), badness, the bad, ugliness, the ugly

Developers are in staging phase and currently four servers is up for testing. Our beta-testers prepare their BIM model and LCA experts improve the auto-link dataset.


The first BIM model is auto-linked to ecoinvent 3.3


UBUBI can perform an LCA analysis, manage an LCA model and save the results. At this point of the research project, UBUBI is still missing some features like: results exploration and comparaison, advance model modification and some automation to generate models from BIM.


The first user interfaces is created and all needed web services.


All requirements are confirmed by partners and the development begin.


The project UBUBI is created and accepted by NSERC.
