The results of principal component analyses of questionnaires, de-veloped after extensive pilot studies, dealing with space, ligh-ting, distractions, positions of class-rooms and overall evalua-tion of school buildings, completed by 510 teachers are presented. These questionnaires were cast in the form of grids and thus al-low for anexaminatjon of the salience of elements (aspects of buildings) or constructs (descriptions of those aspects). In ge-neral it is found that differentiation of the elements is more dominant than differentiation of the constructs. The items selec-ted to form standard scales for building evaluations are indicated.
