摘　　要：The accurate prediction of the visual comfort zone in an indoor environment is difficult as it depends on many parameters.This is especially the case for large compact urban areas in which the density and shadow from neighboring buildings can limit the accessible daylighting in indoor spaces.This paper investigates the satisfaction range for illuminance regarding indoor air temperature in office buildings and the significant parameters affecting this range in six office buildings in Tehran,Iran.Lighting comfort has been evaluated by a subjective survey(509 total responses)and field measurement.The questionnaires were filled out in 146 and 109 rooms in summer and winter,respectively.The results show that the illuminance should not be less than 550 lx,while illuminance between 600 and 650 lx provides the highest satisfaction level.The satisfaction with lighting level is affected by individual parameters such as age,type of activity,and environmental parameters such as window orientation,external obscurations,and season.A relationship was observed between lighting level satisfaction and thermal condition acceptance,and the overall comfort depends more on thermal conditions than the lighting level.
