This study aims to establish the framework of cost-benefit analysis of greening control regulations for public administration as a part of Regulatory impact analysis by evaluating an application of an ordinance to Osaka city. This study measures the followings by use of the consumer surplus measurement approach. 1) The fluctuation of social net benefit as the result of the change of the demand of buildings, because the demand changes due to the increase of building cost by the regulation. 2) The fluctuation of social net benefit as the result of the change of the social average cost by two reasons. The one is the increase of the average (internal) cost caused by the greening cost. Another is the decrease of the social average cost caused by the external effect of greening. As a result, this study can offer an experimental model of cost-benefit analysis of greening control regulations. Moreover, this study finds the possible errors due to the difference between the result of Cost-benefit analysis by the experimental model and the reality, and the direction and the extent of the effect of the errors.
