evaluation method of aging public buildings in consideration of their historical and culture value

Abstract

There are some old public buildings which are constructed in Taisyo era and early Showa era in many cities in Japan. It is necessary to preserve such buildings. However the method of evaluation of those buildings is not established yet. So that we researched to verify the evaluation methods on a case study of Yokohama Meteorological Observatory office building by using of Conjoint Analysis Method in order to compare the Contingent Valuation Method with Analytic Hierarchy Process. The result of willing to pay by Conjoint Analysis Method was similar with the result of it by the Contingent Valuation Method. It is considered that the both of Contingent Valuation Method and Conjoint Analysis Method are available for evaluation of aging buildings. However there is a few different result of evaluation of three actions by the administrative office for promoting to support citizens to understand the project of preserving the aging building with them. It is necessary to conduct a research about the evaluation method of aging buildings continuously.
