The present study performed subjective evaluation experiments using slides and scale‐down models in order to propose guidelines for lighting environment desirable for each behavior in the office. The evaluation measure was composed of 20 mood items and 15 behavior items. As for experiment methods, the slide experiment used SD method, and the scale‐down
model experiment used Scheffe’s paired comparison.
The results of this study are as follows.
1) Desirable lighting environment for “working“ is uniform lighting using general lights with fluorescent-lamp. 2) Lighting environment desirable for ”non-working“ is non-uniform lighting using candescent lamps and local lights. 3) Lighting for working requires bright illuminance and high color‐temperature(6000K). 4) Lighting for relaxation requires low illuminance and middle color‐temperature(4000K). 5) For conversation, bright illuminance is more desirable than dark one, and the most adequate color temperature is 6000K.
