The project is based on defining a Business Intelligence (BI) workflow for the product NECADA, commercialized by Polyhedra Tech SL, which is a spin-off from the UPC.NECADA s main objective is to improve the sustainability of some buildings through data. In this thesis, we choose a properly BI toolthatmatchestheirneeds.Particularly, NECADA needs a tool able to be used by non-technical staff. It must also be able to ingest NECADA s own data coming from simulations, which have a particular structure and they are in XML files. It must also be capable to ingest data coming from sensors through middleware. In order to choose the tool, we have practiced with data, and some​ ​of​ ​that​ ​practices​ ​have​ ​been​ ​recorded​ ​and​ ​the​ ​links​ ​are​ ​along​ ​the​ ​thesis.
