You probably got no reply because everyone was waiting for someone else to answer you; I'm afraid that the answer will disappoint you. You seem to be labouring under the misconception that importing data to OSM is as simple as taking the external data source, pushing it into some sort of software tool, and turning the crank. It is not. It typically takes a very skilled and experienced mapper, who is also a skilled programmer, and familiar with the data model of both OSM and the data source. It also requires detailed familiarity with the data source, so as to be able to assess data quality and consistency, and detailed planning for how to conflate data with what is already in OSM - importing over top of someone else's hard work is considered vandalism. There also needs to be either explicit permission from the data owner or else a legal assessment that the data are available under license terms compatible with ODBL. In fact, that's the first step: determine whether we can lawfully use the data at all. If this hasn't put you off and you still want to go ahead with such a project, you MUST become familiar with the material in https://wiki.openstreetmap.org/wiki/Import/Guidelines and https://wiki.openstreetmap.org/wiki/Automated_Edits_code_of_conduct and then open the import discussion, here and in the appropriate talk-* list. The import guidelines will give you an idea of the sort of questions that you should be prepared to answer. (It's perfectly all right not to have all the answers at first - part of the 'community buy-in' phase is to put you in touch with people who can help you research the answers.) In any case, whether you go ahead with the import or not, please make sure that your external data set is listed among 'Potential Datasources'. Even if we come to the conclusion that the import is a bad idea, that will provide a place to document WHY it's a bad idea to save the next mapper the work of proposing it. It appears that for the Netherlands, the page at https://wiki.openstreetmap.org/wiki/Potential_Datasources leads to https://wiki.openstreetmap.org/wiki/Bestaande_geodata_hergebruiken . I don't see any sources of building data listed there, so it's possible that's not the current place people are using to list data sources. It would probably be best to ask in http://lists.openstreetmap.org/listinfo/talk-nl - the Wiki page looks pretty stale. Hope this helps, and sorry that it's not easy, but it isn't.
