The objective of this study is to clarify the influence of adaptation time and initial adaptation level by applying a suitable illuminance for relaxation that is adjusted by the subjects and evaluations of their satisfaction level of a space in terms of relaxation. The experiment is carried out in a room of W2.7m×D2.7m×H2.6m with floor reflectance 26% and wall reflectance 93%. The experiment is conducted under six different conditions that are set by combining two initial adaptation levels of 20 lx and 150 lx, where the subjects are adapted before entering the room and three patterns of lighting methods, namely luminous ceiling, point source at the center of the ceiling and point source at the center of the wall on the right of the subject. The following results are obtained through this study.<BR>1) The adjusted illuminance and satisfaction level suitable for relaxation are influenced by elapsed time and initial adaptation level.<BR>2) The influence of initial adaptation level on adjusted illuminance is compatible with the influence of elapsed time.<BR>3) The adjusted illuminance for relaxation obtained in this study is lower than that proposed in previous studies and the major reasons for this are considered to be the initial adaptation level and the length of time afforded to the subjects before making their evaluations.
