About the space that a designer planned, we developed the system for simplified forecast of comfort on post occupancy environment. This is the system which designer and building-owner are able to get support in case of planning to improve comfort in the office space. In this system, user describes the space which they want to evaluate comfort in terms of component's grade. After user select early frequency distribution equivalent for component's grade, this system does output frequency distribution forecast of comfort on post occupancy environment with method of exchange by varoius weighting coefficients. As a result, the distribution actually measured by test closely matched the distribution forecasted by above procedure. We could verify that this system is potentially capable of doing "Ante Occupancy Evaluation" on office environment, and that the assumption which was introduced in the middle of forecasting distribution is not greatly beside from the process of comfort-judgement by human subjects.
