This study examined the method of lighting preferred for indoor behaviors. Level of illuminance and uniformity of illuminance were used as the parameters affecting preference. A questionnaire survey and experiments on scale models revealed the following facts : (1) Bright lighting is preferred for "active" behaviors that involve "personal interaction" and require "concentration" and "tension". Uniform lighting is preferred for behaviors requiring "concentration" and "tension". (2) Office behaviors requiring "concentration" and "tension" are associated with higher preference given to higher illuminance and a narrower range of acceptable illuminance in comparison with living-room behaviors characterized by "relaxation" and "comfort". (3) Office behaviors require a high level of illuminance in spaces surrounding the work surface, in addition to the sufficient illuminance on the work surface. On the other hand, living-room behaviors do not require a high level of illuminance in the surounding areas if the work surface is illuminated sufficiently. (4) The lowest illuminance of non-uniform lighting preferred by individual persons coincides with the lowest acceptable illuminance of uniform lighting. The average of the preferred illuminance of non-uniform lighting is located between the highest and thc lowest limits of acceptable illuminance found for uniform lighting.
