Abstract
Earthquake damage envisaged in our country belonging to frequent seismic zones is also enormous,
but a structure that economically supports restoration like earthquake insurance is extremely weak.
The purpose of this research is to appropriately evaluate the resilience performance of businessbuildings (business resilience support capacity as buildings such as earthquake resistance,
resistance to power failure, energy saving, BCP formulation, recovery easiness). To establish anevaluation technology that enables excellent buildings to transfer earthquake risk with a low burden.
To that end, the indicators obtained from evaluation technology are not only engineering experts, butalso developed resilience indices of buildings that can be understood by non-life insurance companies,
banks, bond market participants and others involved in risk transfer, It is required to provide that itis things. Originally we considered earthquake insurance as the main method of risk transfer but
because it turned out that the asset size of the damage insurance company in Japan is small and it isdifficult to undertake further earthquake risks, we will limit the method of risk transfer toearthquake insurance only The objective was to develop an evaluation method that can beunderstood by other financial institutions and investment stakeholders that can be used for general
purpose in other risk avoidance methods. Information relating to such resilience of buildings isappropriately provided to the real estate market, investment in excellent buildings proceeds withinvisible markets, contributing to safety and security without public assistance such as subsidies. We
aim to contribute to the formation of a society in which the qualitative improvement of building stock
is performed autonomously.
In this research, the following research was carried out with the support of the Secom Science andTechnology Promotion Foundation.
1. Evidence collection of resilience information in domestic buildings: We conducted a survey aimed
at clarifying the actual condition of earthquake damage of domestic and overseas buildings andbuilding evidence to evaluate the resilience of buildings using the data. In the survey of the Tohoku
district Pacific offshore earthquake that took place in 2014, we clarified the effect of reducing thedamage caused by the operation management of building facilities for commercial buildings. In thesurvey of the Kumamoto earthquake conducted in 2016, we investigated the damage situation ofaquarium facilities and built damage function considering earthquake resistance performance using
the damage data.
2. Develop resilience evaluation method for building corresponding to reinsurance, bond market, realestate investment market etc.: We comprehensively evaluated seismic performance and disasterprevention performance of business buildings and developed a resilience evaluation method forbuildings aimed at responding to reinsurance and bond market real estate investment market etc.

3. Creation of evaluation examples for domestic buildings: The above evaluation method wasintroduced to 8domestic buildings and evaluated.
