Abstract: A method for designing indoor lighting includes disposing a first luminaire on a ceiling surface that forms an indoor space, the first luminaire having a luminous intensity distribution characteristic that a luminous flux over a range of luminous intensity distribution angles no smaller than 90 degrees but no greater than 120 degrees with respect to a vertically downward direction, which represents 0 degrees, is 20% of a luminous flux of the luminaire or greater and a luminous flux over a range of luminous intensity distribution angles no smaller than 60 degrees but smaller than 90 degrees is 20% of the luminous flux of the luminaire or smaller; and disposing a second luminaire in the indoor space, the second luminaire illuminating a wall surface present in a region corresponding to the luminous intensity distribution angles of light from the first luminaire no less than 60 degrees but smaller than 90 degrees.
