An object of the present invention is to provide a cluster classification device, an environment generation device, and an environment generation system for classifying environmental conditions for constructing an environment having a specific effect on a human body and / or mind. Kind Code: A1 Abstract: Cluster classifying devices 50 and 60 include environmental condition obtaining units 51 and 61, classifying units 52 and 62, and storage units 54 and 64. The environment condition acquisition units 51 and 61 acquire environment conditions for generating a predetermined environment in the target space S. The classifying units 52 and 62 generate clusters from the plurality of environmental conditions acquired by the environmental condition acquiring units 51 and 61 based on the characteristics of the environmental conditions. The storage units 54 and 64 store the clusters and the characteristics of the clusters in association with each other. [Selection diagram] FIG.
