The objective of this study is to investigate the integrated and also individual relation between occupant satisfaction with IEQ factors and building characteristics, workspace and personal factors. As a result of Structural Equation Method analysis, 'distance from window' was relatively strong effective factor on all occupant satisfaction with IEQ. 'Gender' factor is relatively most effective on satisfaction with thermal environment and IAQ and, on the contrary, 'office type' is relatively effective factor on satisfaction with acoustic and lighting environment. As the number of occupant is more, as the glazing type is operable, and as the seat of occupant is nearer the window, satisfaction with all IEQ factors was higher. 'Distance from window' and 'glazing type' showed interaction effect on satisfaction with IEQ, which represents that occupants near operable windows are more satisfied. 'Gross square feet per floor' had negative effect on satisfaction with IEQ.
