In this paper, renovated performance of evacuation safety of converted buildings, from office to residential and welfare facilities, is analyzed quantitatively, calculating by "Verification method for evacuation safety". Performance of evacuation safety is estimated by "the marginal time" which is the remainder of "the time taking to clear the fire room" from "Smoke filling time". Converted buildings are analyzed below process, (1) "The marginal time" is calculated for former plans as office occupancy. (2) "The marginal time" is calculated for present plans as converted occupancy. Comparative studies are made by checking "the marginal time", difference between converted plans and former plans. (3) Problems or weak points of converted plans are pointed out from a viewpoint of performance based evacuation safety. Secondly improved plans are proposed with "the marginal time". Comparative studies are made by checking "the marginal time", difference between improved plans and converted plans.
