Remodeling can be a means to increase building’s physical life-cycle and also a countermeasure to cope with the changes in use that are from social demand, use and technical development. The performance evaluation on the remodeling tenement shall be done by understanding the performance and state of the building before and after remodeling and then it shall represent the improvement in performance objectively by comparing the differences before and after remodeling. In this aspect, we performed basic research to conduct performance evaluation on the remodeling tenement by comparing and analyzing the performance evaluation and performance certificate systems of Korea and Japan in order to suggest objective evaluation system on the change of tenement building before and after remodeling. Now a performance evaluation system as opposed to new apartment is prepared at a point in time when demand increase of remodeling is expected, and the presentation of performance evaluation as opposed to a whole, now remodeling process is the deficient fact. The process that the propriety of
remodeling be inspected before remodeling enforcement here, and prove as opposed to an investment after remodeling as a client, ordering is necessary by all means. A state of an existing house is grasped through performance evaluation of an existing apartment, design performance evaluation of remodeling apartment, under construction evaluation, completion evaluation by this study. And plan of a procedure to provide satisfaction to a resident because a remodeling design to be good for the situation and a demand of a resident and execution were measured, and confirmation evaluated, result performance was shown.
