Abstract: The delight of architecture has always been an architectural attribute as important as firmness and commodity， which emerged from the “venustas” of the Vitruvius era and evolved into the delight of the Pritzker Prize. In the contemporary context， what are the new meanings of architectural delight？ This paper attempted to reinterpret “delight” in terms of psychology and environmental behavior science， and summarized the spatial configuration characteristics corresponding to the specific elements of delight by spatial syntax to reveal people's real spatial experience in buildings.This method and specific elements of subjective experience were applied to post-use evaluation （POE） of buildings to develop and improve the existing post-use evaluation system.
