Use of scale models for appraising lighting quality

Abstract

This paper discusses some of the theoretical problems of the use of scale models. Findings from a number of experiments on the validity of models are discussed. Generally, these experiments show a degree of similarity of observer responses to full-size mock-ups and scale models. However such similarities do not dispel the possibility that scale models and indeed full-size mock-ups are not true facsimiles of the real world because of the artificiality of many experimental set-ups; there is always a need for some field validation work. With the tendency towards using 'subtle' psychological measures for environmental evaluation rather than explicit criteria as in psychophysical experiments, further studies are urgently required.
