To address the aging of public facilities, the Ministry of Internal Affairs and Communications requested municipalities to formulate a “Comprehensive Management Plan for Public Facilities and Infrastructure” in 2014. 9 years have passed since then, but only a few municipalities have analyzed and understood the progress of public facilities development from its formulation to the present. Additionally, the fixed asset ledger, which contains accounting information from construction to disposal of public facilities, is expected to be utilized for facility management. Therefore, this report proposes a method to grasp the progress of public facilities development using the fixed asset ledger.

As a result of the changes in where people work due to the impact of COVID-19 pandemic, co-working spaces are also undergoing changes. To capture changes in the operation of co-working space facilities and describe current needs, challenges and prospects, a survey on operations was conducted among co-working space operators and compared with the 2019 survey. Compared to 2019, the results show that the total number of co-working spaces has increased, but that there is an increased emphasis on individual use, while a higher proportion of facilities that focus on interaction are updating their facilities.

In recent years, due to changes in social conditions such as "development of ICT environment" and "work style reform", the number of workers who are not bound by the framework of places and organizations is increasing, and coworking spaces are increasing as places where those people work. The coworking space is not just about sharing the place to work but it is characterized by sharing wisdom and information and creating value by exchanging information, but since there are few previous studies. Therefore, the research is conducted with the aim of using it as a basic material for future facility planners and operators to plan and operate coworking spaces. First, by conducting a questionnaire survey of domestic coworking spaces, we grasp basic data on facilities, operations, plans, and users, analyze the correlation of each answer, and analyze the relationship between operation policy, exchange policy, location, and the business they are doing together. In addition, we clarify that five clusters are generated by cluster analysis with scale and land price as variables, and each cluster is characterized by the response tendency such as building ownership, operating entity, initial investment cost, user base, operating purpose, and exchange policy. Next, three facilities were selected from the cluster named "Large-scale high land price type", and behavior observation surveys and interview surveys were conducted with users. From behavioral observations and interview surveys with users, users select the place by comparing it with other places, and build it as a place suitable for themselves by continuing to use that place while paying attention to the relationship with others. It was used to move seats when the user changed the work content or changed his mood. It turned out that many people use it as a substitute for their home or office, and it is recognized as a base for telework. In addition, it is considered that the exchange between users is brought about by the mutual relationship between the users' willingness to interact, the intervention of the operator, the appropriate replacement of people, and the place that triggers them.In addition, we conducted an interview survey with the operators of similar facilities. The interview survey with the operator was analyzed with reference to the M-GTA method. The process that the operator selected as the right person in the affiliated organization updates the layout and system of the facility while gaining awareness and conflict while operating based on his ideals and the needs of the users was clarified and shown with specific update cases. From the above, we have shown the process of creating a new space, a coworking space, in which users and operators interact with each other at this research facility. In the future, we think that it will be possible to discuss the differences between the image of users and the image of operators by increasing the number of survey cases, such as targeting different clusters.

1.IntroductionAging of public facilities, declining population and increasing local government finance have been questioned conventionally. From such as situation, In April 2014, the Ministry of Internal Affairs and Communications requested municipalities to formulate a "Comprehensive Management Plan of Public Facilities and Infrastructures". In the plan, the facility reduction target and basic policy are described using uniform calculation of renewal and renovation expenses. However, the construction transition of public facilities differs from municipality to municipality, and the uniform calculation does not provide an appropriate analysis. 2.Purpose of This StudyThe purpose of this study is to consider public facilities improvement policies according to the differences of construction transition. 3.Research MethodThe method is classifying in the transition patterns of target municipalities by cluster analysis. Then, we estimate renewal and renovation expenses and reveal features and problems by each cluster. 4.Research ResultThe results of this study are summarised below.1) By constructing the database of public facilities, it becomes possible to compare between municipalities.2) The construction transitions of public facilities are classified into 4 types. These types are Economic growth period peak type, Early peak type, Two peaks type and Continuous construction type.3) The transitions of renewal and renovation expenses are different for each type, and improvement policies such as reduction and leveling are also differ from type to type.・ Municipalities that constructed public facilities in particular from 1950 to 1970 need to reduce public facilities quickly because it is difficult to level out renewal and renovation expenses due to early renewal period and many facilities that have not been renovated.・ Municipalities that built intensively public facilities around 1980 have to level out expenses by renovating the facilities that have not been renovated and accelerating renewal time during the period up to about 2060. It is effective in reducing school facilities, government office, parenting support facilities and public housing built around 1980.・ For municipalities that have continued to construct public facilities since 1990, it is desirable to consider renewal and renovation together and level out the expenses including the next about 40 years. They need to investigate surplus public facilities except school facilities and plan for reduction in those facilities.

Due to COVID-19, university campuses have been closed since April 2020, and campus space usage was restricted. The significance of campus space will be discussed by comparing the campus use by the students before and after the self-restraint. A web-based questionnaire survey was conducted on 6,789 students to identify the actual situation of activities such as classes and interactions, as well as their keen opinions through open-ended responses. Restrictions on campus use lead to the loss of interaction and campus spaces for students to study and to live. This research clarifies the significance of campus space for future campus planning.

Many local governments are currently undergoing public facilities restructuring plans. In this research, we focus on ‘change of management entity’ which is to delegate the management of the property from local government to the private sector. Changes of management entities of the meeting place are conducted for facilities targeting small scale areas corresponding to self-government associations, and many of the change-destination of management entities are self-government associations. Although it is effective in the short term as a method to ensure the continuation of the activities of residents so far, it has become clear that the long-term maintenance has many issues.
