PROBLEM TO BE SOLVED: To provide an illumination space evaluation method, an illumination space evaluation program and an illumination space evaluation device which can shorten design work for making an illumination space close to an ideal state.SOLUTION: A brightness feeling 85 being an evaluation value expressing an impression of brightness felt by a human being is calculated on the basis of a luminance image 83 indicating the luminance distribution of an illumination space, a luminance graphic 84 having a specific luminance distribution is added to the luminance image 83 and the brightness feeling 85 is recalculated after addition. These processes are executed by a single program 9 installed in an information processor. In this way, a user can, not only calculate the brightness feeling 85, but also immediately know on the single program 9 about a position to which a lighting fixture should be added in the illumination space and a type of the lighting fixture which should be added in order to make the brightness feeling 85 close to an ideal value. Thereby, the design work for making the illumination space close to the ideal state can be shortened. |
