The author has developed a quantitative evaluation method of building performance from a viewpoint of Facility Management. This method is expected to contribute to corporations' business improvement by means of optimization of building facilities as management resources. In this method, the author adopted hierarchically defined function items, AHP method and fuzzy integral. A case study has proved the possibilities of this method. On the other hand, it admits alternatives of variables based on values. For this reason, consent of values through collaboration and feedback is required in order to refine the method for practical use.
