Ask all your questions to Minister André Antoine
Minister André Antoine will be at your disposal during the 2008 edition of the Batireno Fair and will answer your questions on renewable energies, construction and renovations.
If you wish to meet him personally and ask him questions relating to your particular case, the Minister will be at your disposal on his stand on certain days between 20 and 28 September at Namur Expo. Due to an agenda subject to regular changes, the schedule of his presence will be announced on his website: www.antoine.wallonie.be

I do not know if he will spend a lot of time there but I find it rather nice to be exposed directly to the technical questions of the public.
