Social Responsibility Initiatives for Residents and Tenants
Role of SHR with Respect to Residents and Tenants
In recent years, the significance of SHR’s efforts to provide resilient buildings that can withstand disasters, etc., and to minimize damage in the event of a crisis has become greater. We believe that our role is to make the properties owned by SHR a place that provides safety and peace of mind, and to make it a comfortable place that improves the quality of life on a daily basis.
SHR seeks properties that are located in suitable locations to provide a “sustainable base for living” for residents and a “sustainable base for business operation” for tenant companies. Based on the recognition that the need for real estates that have high residential functionalities including comfort and safety or the components desired by tenant companies is increasing, SHR designates “high quality” residential and commercial properties, etc. located at “strategic locations” as “Prime Properties” and prioritizes investments in such properties.
Through investments in properties that qualify as “Prime Properties”, SHR will pursue both sustainable lifestyles and business activities for its residents and tenants, and the sustainable asset management of SHR.

Safety, Security, and Comfortability for Tenants
Measures against Earthquakes
SHR's investment criteria require that the company's domestic portfolio has a seismic PML (probable maximum loss) of 10% or less in principle and that the addition of earthquake insurance is considered for an individual property with a PML of 20% or more. The seismic PML of SHR's domestic portfolio as of October 31, 2024, was 2.4%; there were no individual properties with a PML exceeding 20%.

Measures against Flooding
SHR has a system for minimizing damage from natural disasters by investigating the risks of inland flooding, river flooding and storm surge for our owned properties in Japan to assess domestic flood risks and use the findings to improve our business continuity plan (BCP).
The percentage of our domestically owned properties with a flood depth of 0.5 meters or more account for 55.0% (As of October 31, 2024).

Residence in Preparation for Disasters
Prime Maison Shinagawa is a rental condominium developed by Sekisui House in response to rising concerns about power conservation and disaster prevention performance following the Great East Japan Earthquake, in addition to climate change. This property has an emergency power generator that was introduced to ensure a higher level of safety and security in the event of an emergency. The generator is connected to solar batteries and storage batteries, ready to serve as an emergency power supply system for use in the event of a blackout.


Conceptual Diagram of Emergency Power Supply System

When power is cut due to a natural disaster or similar event, the emergency power generator is activated and supplies power to common areas for approximately 19 hours. It can continue to supply power even longer when connected with solar batteries and storage batteries. As a result, some lights for common corridors and the entrance are illuminated, securing passageways and providing a sense of security even at night. In addition, the generator also supplies power to the electrical outlets in the entrance, where residents would gather, allowing them to charge mobile phones and other devices. The generator also permits the collection of information via the monitor in the control room. Power is also supplied to the feed-water pump. This means that water will be supplied to common areas and dwelling units as long as the water supply has not been cut off.

Disaster-Resilient Office Buildings
Hommachi Minami Garden City takes business continuity into account by installing seismic braces on each floor to absorb the forces that would act on the building in a major earthquake, and by situating its mechanical room on the 3rd floor, above flood level. Despite these features, it still offers over 1,300 square meters of column-less spaces and a ceiling height of 2.8 meters on standard floors.


At HK Yodoyabashi Garden Avenue, the floor level of the first floor has been raised by 0.5 m from the front road on the north side to prevent flooding into the building, in readiness for flooding damage due to torrential rain, etc. Flooding countermeasures have also been implemented in the B1F parking lot, which is susceptible to damage due to rainwater flowing in from the road. Electrically operated waterproof panels that activate automatically when a sensor detects a certain amount of flowing water are installed at the entrances and exits of the roadway ramp to prevent possible flooding damage. We have also installed emergency generators for buildings that can supply power to both common and exclusive areas, and are able to supply power for up to 48 hours even when the supply of power from the power company is stopped, ensuring business continuity.

Conducting Tenant Satisfaction Surveys
SHR regularly conducts tenant satisfaction surveys with the aim not only to improve and stabilize leasing operations, but also to communicate with residents and tenants and build reliable relationships.
For the surveys conducted in fiscal year 2023, we incorporated questions asking about their initiative status of implementation and in-house discussions related to ESG and well-being into the survey items.
The survey results are shared with property management companies, building management companies and others, and measures will be developed to further improve services.

Selection and Evaluation of Property Management Companies
In order to secure stable earnings and maintain and improve the value of assets, SHR has established criteria for selecting property management companies to which such management may be entrusted. In principle, SHR monitors and evaluates the performance of property management companies' management operations once a year through external evaluation organizations, and verifies their appropriateness.
In addition to the company's property management capabilities and operational systems, its organizational structure for promoting corporate sustainability and the energy conservation promotion system for managed properties are also subject to evaluation. For property management companies that receive relatively low ratings on sustainability-related items as a result of the monitoring, SHR interviews them to share details of SHR's approach to sustainability and strengthens our relationship in promoting initiatives as one.
