SHAM is pursuing the following initiatives for properties owned by SHR, in accordance with Sustainability Policy.

Introduction of environmentally friendly facilities

We have introduced environmentally friendly facilities, including solar power generation panels, LED lighting, and Low-e double-glazed windows which has heat shielding and heat insulating functions.

TOPICSCO2 reduction measure for residential properties

(As of April 30, 2018)

Number of owned properties at which lights for common areas
were replaced with LED lighting after acquisition: 44properties

Total approx. 647t-CO2 annual reduction in greenhouse gas (CO2)emissions forecasted

  • Calculations made by SHAM based on materials provided by vendor entrusted with light fixture replacement

Number of replacement of existing air conditioning units with units
rated four stars or higher in exclusively owned areas after acquisition: 836units / AC

Comparison of air conditioning units with “two stars” energy efficiency and those with “four stars” energy efficiency

Total approx. 88t-CO2 annual reduction in greenhouse gas (CO2)emissions forecasted

  • Calculations made by SHAM based on materials, etc. released by the Ministry of Economy, Trade & Industry's Agency for Natural Resources and Energy.

TOPICSCO2 reduction measures for commercial properties

  • ~ Participated in the CO2 Reduction/ Lights-Down Campaign, which is organized by the Ministry of the Environment ~

The Ministry of the Environment has annually carried out the CO2 Reduction/Lights-Down Campaign, which calls for people to turn off the lights of illuminated facilities as a countermeasure against global warming, around the summer solstice since 2003.
From 2008, the ministry began to encourage participation in Cool Earth Day Lights Down on July 7, Star Festival Day, in addition to Lights-Down around the summer solstice.


Safety and Security Measures

The measures we take in consideration of the environment and local communities include management by the disaster prevention center operating 24 hours a day, 365 days a year. We also install and introduce equipment for the security and safety of tenant companies and residents, one by one or at certain properties.


TOPICSInstallation of solar battery, storage battery, and emergency generator at Prime Maison Shinagawa

  • Prime Maison Shinagawa is a rental apartment that was developed by Sekisui House in response to rising concerns about power conservation and disaster prevention performance, in addition to the prevention of global warming, following the Great East Japan Earthquake. 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 with 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 to Prime Maison Shinagawa 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 traffic lines 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 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 is supplied to common areas and dwelling units provided the water supply has not been cut off.

Biodiversity Measures

Based on the “Gohon no ki” (Five Trees) Planning, which is promoted by Sekisui House as the sponsor of SHR, we conduct maintenance and management of planting and other greenery measures, basically by selecting tree species in consideration of ecosystems.

“Gohon no ki” (Five Trees) Planning Promoted by Sekisui House

“Gohon no ki” (Five Trees) Planning is a Sekisui House original proposal for the creation of gardens and communities where the ecosystem is taken into consideration and local indigenous trees are used for gardening. In this planning, “Five Trees” indicates that Japanese indigenous trees will be promoted as “three trees for birds and two trees for butterflies.”

TOPICSGotenyama Project, a large-scale complex with a green landscape based on the “Gohon no ki” (Five Trees) Planning

Gotenyama Project, which is comprised of Prime Maison Gotenyama East, Prime Maison Gotenyama West, Garden City Shinagawa Gotenyama and Gotenyama SH Building developed by Sekisui House, is highly evaluated by public institutions as an excellent example of greening trough urban regeneration because it has created a large-scale area of greenery that contributes to the natural restoration of the local area.

Contribution to Local Communities

SHR introduces equipment that is available to anyone in the event of an emergency, participates in local community events near its owned properties and takes other initiatives to deepen communications and harmoniously co-exist with local communities.

TOPICS~ Examples of initiative for harmonious co-existence with local communities: Hommachi Garden City ~

We take initiatives for contributing to local communities by using pilotis and entrance halls of properties we own.

Conducting tenant satisfaction surveys

We intend not only to improve leasing and achieve stable operation but also to communicate and build a reliable relationship with tenants as well as conduct tenant satisfaction surveys to collect the opinions and requests of tenants, as needed. The results of the surveys are shared with the property management company, building management company, etc. and are used to enhance services.

Registration in “COOL CHOICE” at SHAM

SHAM supports “COOL CHOICE”, a national campaign promoted by Ministry of the Environment as measures against global warming, and takes the following initiatives as environmental measures.


  • Maintaining moderate temperature settings on air conditioners
  • Promoting Cool Biz and Warm Biz
  • Promoting a paper-free environment for internal materials by using iPad and a shared server
  • Stopped using paper cups in the company, making it a rule for individuals to bring their own cups

Conducting employee training, etc. at SHAM

We regularly conduct compliance training, human relations training, disaster drills, etc. with the intention of providing an understanding of governance, improving the working environment and implementing disaster prevention measures for employees at SHAM. In addition, we regularly conduct workplace gatherings to discuss requests, etc. from employees with the intention of enhancing employee satisfaction by improving the working environment.

Trends in the amount of consumed energy, CO2 emission and used water in owned properties

We promote various efforts to reduce environmental burdens such as activities described in the above "Example of CSR and Environmental Activities" as well as through efforts to understand the amount of consumed energy, CO2 emission and used water in owned properties by SHR.
