The principal item of a full-scale lab preferably features a court-like facility where the 1:1 simulations are performed. Such lab facilities can be found at various architecture education centers throughout Europe. In the early eighties the European Full-scale Modeling Association (abrev. EFA, full-scale standing for 1:1 or simulation in full-scale) was founded acting as the patron of a conference every two years. In line with the conference title "Full-scale Modeling in the Age of Virtual Reality" the participants were particularly concerned with the relationship of physical 1:1 simulations and VR. The assumption that those creating architecture provide of a higher degree of affinity to physical than to virtual models and prototypes was subject of vivid discussions.

Furthermore, the participants devoted some time to issues such as the integration of model-like ideas and built reality thus uncovering any such synergy-effects. Thus some major considerations had to be given to the question of how the architectís model-like ideas and built reality would correspond, also dealing with user-suitability as such: what the building artist might be thrilled with might not turn out to be the residentsí and usersí everyday delight. Aspects of this nature were considered at the îArchitectural Psychology Meeting” together with specialists on environment and aesthetics. As individual space perception as well as its evaluation differ amongst various architects, and these being from various countries furnishing cultural differences, lively discussions were bound to arise.
