抄録

This research deals with the economical advantage of condominium, which permit resources circulation for a better sustainable society. We set up a model of renewal cost, which can respond to user's life stages, and calculate the life cycle cost for 180 years using the present value method. The result of this study has convinced us that the resource circulation housing provides an economical advantage, e.g. while its cost is 20% higher than the conventional housing the real rate of interest is 2%, which will give an advantage of 20% over conventional housing. And that its inheritor has an economical advantage in the life span cost, to be 40% lower than the original builders.
