In Belgium there are two possibilities to study architecture, it can either be done at a higher institute or academy, or at a university. At the higher schools of architecture the computer equipment has just been installed during the last years, and teaching of CAAD is not yet integrated. There exists only a general computer course. At the universities hardware has been available since several years, and software has been developed. The following programs have been implemented in Liege: LPB1, LPB2, LPB3, LPB4 (energy analysis), FEASIBILITY (to obtain acceptable values for the main global parameters of a design), VOLUME, (3D modelling for building modelisation and manipulation) and TYPOLOGIE (for the determination of classes for the energetic behaviour of residential buildings).
