"Working" from various environments e Implementing a new ABW approach that allows students to choose "ELD"
Innovation Hub

The design concept for this facility is to develop a variety of workplaces by linking the outdoors, semi-outdoors and indoors together as an "environmental gradation" that combines a variety of spatial, temperature, humidity and lighting environments, rather than separating the inside and outside of the building as is the case in typical research facilities.
The concept of "ABW +e" combines ABW (Activity Based Working), which allows users to choose where they work, with air conditioning control and lighting plans tailored to the characteristics of each location, and adds a wide variety of environments, including air, lighting, and spatial scale. The aim is to create an innovation hub filled with "Feel / feel + Field / place," where people can"feel" the spark for reflection, realizations, and new value creation.

  1. A building with zero or negative net annual primary energy consumption.
  2. An evaluation by the Institute for Building Environment and Energy Conservation of the specifications, performance, and initiatives of buildings that help maintain and improve the health and comfort of building occupants.

This follows the "Mitsubishi Electric ZEB-related Technology Demonstration Building "SUSTIE"" (completed in October 2020) and the "Shobond Construction Northern Japan Branch New Building" (completed in June 2023). Please see the end of the release for details.

"SOU-SOU VOID" is a semi-outdoor space located in the center of the building that stretches from the 1st to 3rd floors. It was named after the two characters "so" and "sou" in Shinryo Corporation's management vision of "creating a refreshing world and contributing to the sustainable development of society."
It is a semi-outdoor space where you can feel the light and breeze, characterized by natural ventilation, skylights, and a large wooden eaves roof that continues from the outdoors.

By using circadian-controlled ambient lighting, underfloor air conditioning, and condensation-type radiant air conditioning to cool the living areas, we have achieved a comfortable environment in this large, open space while also saving energy.

On the southeast side, under a large roof that prevents sunlight from reaching directly into the building, there is a workplace connected to the interior.

Generally, openings (windows) allow sunlight and heat to flow in and out, so in buildings aiming to be ZEBs in particular, the opening ratio tends to be reduced when the building envelope performance is prioritized for energy conservation. However, the large roof provides a 12.5m-high glass surface, creating a sense of openness.

Implementing "full BIM design and construction" throughout design and construction projects

In designing this facility, we used BIM at every stage, from schematic design to detailed design development to Construction Supervision, to check for and resolve any interferences, study the design, and share information with the business operator and contractor. (Selected for the Ministry of Land, Infrastructure, Transport and Tourism's "Model Project for Facilitating the Construction Production and Maintenance Process Using BIM" / Shinryo Corporation, Takenaka Corporation). We will deploy the knowledge we have gained here in our various future design and Construction Supervision projects, and use it to make our work processes more advanced and efficient.
In addition, in April 2023, we will position BIM as a key element of our DX strategy, transferring the BIM Promotion Office to the newly established DX Promotion Department, and are actively promoting the use of BIM and disseminating/educating people about it within the company.
