Abstract
The aim of this paper is to make the renewal works clear in the facility use conversion. Public buildings can be classified into six types according to the attributes of their users. Through consideration based on the building type with actual plans, it is found that there are characteristic relation between the entrances of the converted plan and the old plan. Comparison analysis of the entrances of the two plans, therefore, is effective for our aim. As a consequence of the comparison of the two plans and the details of renewal works, the following facts are confirmed ; 1) Nothing inconvenient to use the new entrance occurs in spite of lower degree of renewal works in the case that the converted building type is same as before, however, 2) Needs for higher degree of renewal works on the change of the entrance occur in the case that the converted building type is changed because insufficient renewal works often bring inconvenience to use.
