Senri Rehabilitation Hospital Annex Building, Wooden Space that Heals Body and Mind

Sumitomo Forestry completed the annex building for Senri Rehabilitation Hospital in Osaka in September 2017.

Most of the conventional hospitals had been built inorganically, with a priority on efficiency from the perspective of the hospital operation. The concept that gave rise to Senri Rehabilitation Hospital is consideration for the patients on what kind of hospital would provide the ideal environment. The annex building was completed in October 2007 as Japan's first hospital to have a concept of rehabilitation resort.

The new annex building built for the 10th anniversary of the hospital maximizes the utilization of wood, both interior and exterior, to enable patients to relax as much as possible and feel the natural power as they undertake their recovery. It is a rehabilitation hospital that represents a new endeavor, with painting and music ward and a gardening ward, all of which use arawashi exposed timber* style.

In order to support those patients who experienced deep trauma through sudden illness and to regain their positive attitude and physical abilities, the hospital offers rehabilitation facilities that are close to real daily life environment. The ultimate goal is to return and live in their own home. To achieve this concept, it chose a design with uneven levels and stairs instead of making the facility completely accessible. In addition, painting and music ward and gardening ward are available separately for patients to find their new joy in life and possibility. Accessing to these wards is part of rehabilitation.

As with the main building, Creative Director Kashiwa Sato has undertaken design direction for the annex building. Paintings by Sato have been incorporated into the interior design to convey a sense of energy.

Wood offer comfort through all five senses, from its aroma, texture, and sound echoes in the air. The qualities of wood contribute not only to physical treatment but also physiological treatment during the stay. This integration of wood and medical sites of this annex building is a great example of the new possibility of MOCCA (Timber Solutions) Business.

In addition to this kind of medical facilities, Sumitomo Forestry aims to create attractive environments that motivate residents and provide impetus for the business success of residents and users by using timber in the structure and interior and exterior finishing materials of educational, elderly care, commercial and other facilities.

Using Wood in Buildings to Help Transform Work Styles- Kokubunji Head Office Building of Flavor Life Co. Ltd.

Flavor Life Co., Ltd., which has its head office in Kokubunji City, Tokyo, provides aroma products that incorporate blessing of nature into daily life. It is a company that creates lifestyles with fragrance and smiles through aromatherapy.

As a company that handles products made of natural materials, wish for a building that used natural materials it is a matter of course to wish Above all else, the company wanted an environment in which employees could work comfortably. A wooden-hybrid building was realized in July 2017 with the passion of the proprietor.

Time spent in a workplace is no fleeting moment for the working people. It is surely fair to say that bringing comfort and coziness to a living space in which so much time is spent to be an important element of in promoting work style reform.

The effects of a peaceful workplace incorporating wood, in which employees say they can relax while working, and communicate more with coworkers, has begun to be reflected in employee satisfaction levels and productivity of work.

This wooden-hybrid building has a steel frame structure for the first three floors and a wooden-hybrid structure for fourth through seventh floors. Its most distinctive characteristic is its use of hybrid laminated engineered wood which the steel frame is completely covered in wood. Featuring a combination of the soft texture of wood and the strength of steel, it enables the wood to protect the steel from heat as a fire-resistant coating, contributing to disseminate incorporation of wood as a material for buildings.

The aim of Sumitomo Forestry is to create vistas lined with buildings that provide a sense of the warmth of wood in cities, where contact with wood is rare. We apply our knowledge and experience in using wood to propose new ways of doing so.

* This project was selected as a pilot program for sustainable buildings (wood type) of Ministry of Land, Infrastructure and Transport in fiscal 2015.

Toward the Future -Aiming for the Timberized Eco Cities with W350 Plan-

Sumitomo Forestry announced its W350 Plan in February 2018. The W350 plan is a research and technological development roadmap aiming to build a 350-meter-tall wooden high-rise building in 2041, which will mark the 350th year since foundation of business in 1961, in preparing to create Timberized Eco Cities . The plan is intended to develop future technologies that contribute to people's lives, society and the global environment, including building construction methods, environmental technologies, wood for building materials and resources.

The plan is to move forward at a new research building of the Tsukuba Research Institute, where frame erection was completed in December 2018, and construction is slated for completion in October 2019.

Toward Realizing the W350 Plan

In February 2018, Sumitomo Forestry created and announced a research and technological development concept “W350 Plan” aiming to build a 350-meter-tall wooden high-rise building by 2041, which will mark the 350th year since foundation of business, in preparing to create Timberized Eco Cities.

Managed mainly by our research and development center, Tsukuba Research Institute, this research and technological development plan is a roadmap for the future technologies; to develop building construction methods, environmental technologies, wood for building materials and resources and will expand the possibility of wooden structures.

This plan of creating Timberized Eco Cities centered on wooden high-rise buildings will revitalize the forestry industry with increased demand of timber and mitigate climate change with increased fixation of CO2; in essence, Sumitomo Forestry will contribute to invigorate the community and to realize coexistence with the global environment.

Building outline:

  • Height - 350m, Number of floors above ground - 70 floors
  • Building use: Stores, offices, hotels, residences
  • Building area: 6,500m²
  • Design collaboration: Nikken Sekkei Ltd.
  • Architectural area: 455,000m² (6,500m² × 70 floors)
  • Amount of timber used: 185,000m³
  • Structure: Wood and steel hybrid structure (Internally, pure wooden structure)

New Research Building of the Tsukuba Research Institute, Which will Serve as the Research Base for the W350 Plan

It has been 28 years since Tsukuba Research Institute was established. The deterioration of the main research building and increase in staff have become issues needing to be addressed. Post-tensioning*1 technique, a new technology related to wooden structures used in this building will form the foundation for the W350 Plan. Energy saving technology and renewable energy will also be used with a view of achieving a zero energy building (ZEB).

The new research building is a three-story building with a floor area of 2,532.67m². The beams, pillars, and walls use arawashi*2 exposed timber that has either received Ministry of Land, Infrastructure, Transport and Tourism (MLIT) certification or has been designed using the semi-fireproofing technique. Full building evacuation safety verification [Route C (Minister’s certification)]*3 makes it possible to eliminate restrictions on wooden interiors so that spaces with the qualities of wood can be presented. The building greatly reduces CO2 emissions by installing solar panels on the roof and adopting absorption water chiller-heaters fired using wood pellets. Research and development of green technologies for non-residential wooden architectural structures will be conducted while office space will be used for verifications such as green layouts that seek to improve intellectual productivity. It will also be used to test greening on the roof, balconies, and external walls.

This facility has been accepted as a pilot program for sustainable buildings (wood type) in fiscal 2017 promoted by Ministry of Land, Infrastructure, Transport and Tourism. Plans include an office for housing 140 persons, and a gallery, etc., to provide information about timber.

With the new research building positioned as the cornerstone of the W350 Plan, we also began a construction plan for a six- to seven-story wooden building (20m to 30m tall) as the next actual step forward. This plan has been named “W30” and is currently under way.

*1 A construction method where high-strength steel poles and wire ropes running through load-bearing members is tensioned to increase the fixation of position between members.

*2 A finishing technique in wooden constructions which structural members such as columns and beams are exposed to view.

*3 A method for verifying safety performance where everyone within a building is able to evacuate safely to the ground level given a pre-determined fire scenario. If safety can be confirmed, some of the regulations of the Building Standards Act of the Japanese government are eased, enabling greater freedom of design, such as exposing wood structural members to view. Route C designation requires certification by the Minister of Land, Infrastructure, Transport and Tourism, but since evacuation safety performance is confirmed using sophisticated calculation methods not stipulated by the notice, it allows for the highest level of design freedom.
