NOMURA Co.,Ltd. opens new recruiting space "Tokeru" - A relaxing space that combines BIM and sustainability -

NOMURA Co.,Ltd. has opened a new space for recruitment interviews called "Tokeru" in Head Office building. This space is designed to ease the tension of job interviewees and allow them to relax and perform at their best.
We handled everything from planning to concept design, planning, and construction. Through the use of BIM (Building Information Modeling)* and a space creation process that achieves sustainability, we embody the way spaces will be created in the future.

*BIM (Building Information Modeling): A system that uses 3D data created on a computer to promote design and construction.


■Project Overview
The concept was "Tokeru (to be able to relax)," which means to ease the tension that occurs during job interviews. The conference room has curved glass and rounded furniture to create a soft impression, and indirect lighting has been used to create a calm atmosphere even from outside. The waiting lounge has a lighted wall, creating a space where natural light envelops the soul.

By utilizing BIM throughout the entire process, we were able to achieve not only a relaxing concept design, but also comfort and sustainability.
・ 3D scan of existing spaces to create accurate models of existing spaces, enabling high-precision design in a short period of time
・Confirming designs using VR allows verification with the same feel as real space at low cost
- Acoustics, lighting, and air conditioning were simulated to achieve both comfort and energy savings (lighting power consumption reduced by 45%)
Furthermore, we calculate and analyze CO₂ emissions and verify reduction measures.

■Space concept
During job interviews, we expect interviewees to be nervous when they visit the venue, so we created the concept of "Tokeru" (to be able to solve) so that everyone can relax and perform to their full potential.
The conference room uses curved glass that gives the impression of soft, melting ice, and the tables and sofas, including those in the lounge, also have a rounded concept design, conveying a visual gentleness and calmness. Furthermore, indirect lighting has been installed between the glass and lace curtains surrounding the conference room, and the transparency has been adjusted so that the silhouettes of those in the room can be seen but their expressions cannot be read. By designing the atmosphere inside to be calming from the outside, a new type of conference room that relieves tension has been realized.
The waiting lounge features a "light wall" that gives the impression of natural light changing with the passage of time. The refreshing, soft light filtering in through the curtains gently comforts users while they wait for their interview and after it has finished, creating a space that gently embraces their emotions.

■ Utilizing BIM and achieving sustainability
This project utilized BIM (Building Information Modeling) throughout the entire process, from concept design to construction, achieving both improved quality and sustainability. 3D scanning of the existing building created an accurate current model, enabling a highly accurate design to be achieved in a short period of time. Furthermore, design verification using VR enabled verification with the same sensation as real space, at low cost. Furthermore, electroencephalogram measurements showed that the spatial experience in VR was close to that of real space.

・Sound planning
We used sound-absorbing panels in the conference room and simulated the resulting comfortable acoustic environment using BIM. This allowed us to verify sound reverberation and conversation clarity in advance, achieving both a soft impression with glass and lace curtains and a comfortable acoustic environment.

・Lighting plan
We conducted an illumination simulation based on the sunlight conditions coming through the large windows. By making the most of natural light and optimizing artificial lighting, we were able to reduce power consumption by 45% compared to the previous system.

・Air conditioning planning
Through simulation using BIM, we were able to optimize the airflow distribution without changing the output of the air conditioning equipment, thereby improving air conditioning efficiency and reducing energy consumption.

Furthermore, we calculate and analyze CO₂ emissions based on BIM data, quantitatively assess environmental impact, and verify effective measures to reduce CO₂ emissions.By utilizing BIM in this way, we can comprehensively manage each element of design, layout, construction, and environmental performance, realizing a space creation process that achieves both high spatial quality and sustainability at a high level.
