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

NOMURA Co.,Ltd. is pleased to announce the opening of a new space for recruiting interviews, Tokeru, in the Head Office building. This space is designed to ease the tension of those undergoing recruitment interviews, allowing them to relax and perform in their own unique way.
From planning, concept design and design to construction, we have been involved in the entire process, and through the use of BIM (Building Information Modeling)* and the space creation process of achieving sustainability, we are embodying the way spaces should be created in the future.

BIM (Building Information Modeling): A system for promoting design and construction using 3D data created on a computer.


Project Overview
The concept of "Tokeru" (to release tension) was set up to ease the tension during employment interviews. The conference room was designed with curved glass and rounded furniture to create a soft impression, and indirect lighting to create a calm atmosphere from the outside. The waiting lounge has a light wall to create a space where natural light envelops the mind.

BIM was utilized throughout the entire process to achieve not only a relaxing concept design but also comfort and sustainability.
The existing space was scanned in 3D to create an accurate model of the existing conditions, enabling a highly accurate design in a short period of time.
Low-cost verification of the design with the same sensation as the real space by using VR
Simulation of acoustics, lighting, and air conditioning was performed to achieve both comfort and energy savings (45% reduction in power consumption for lighting).
In addition, CO₂ emissions are calculated and analyzed, and reduction measures are verified.

■Spatial Concept
Since we anticipate that applicants will be nervous when they visit this location for job interviews, we established the concept of "Tokeru" (meaning "to relax") to help everyone relax and perform at their best.
The conference room features curved glass that gives a soft impression reminiscent of melting ice, and the tables and sofas, including those in the lounge, are concept design with rounded edges to express visual gentleness and tranquility. Furthermore, indirect lighting is installed between the glass surrounding the conference room and the lace curtains, with the transparency adjusted so that the silhouettes of those inside can be seen, but their facial expressions cannot be read. By designing the space so that the atmosphere inside can be gently perceived from the outside, a new kind of conference room that helps to relieve tension has been realized.
In the waiting lounge, we have installed a "light wall" that allows you to feel the changing natural light as time passes. The refreshing and soft light filtering in through the curtains gently soothes the mind while waiting for an interview and after it has finished, creating a space that calms the emotions of our users.

■ BIM utilization and realization of sustainability
In this project, we utilized BIM (Building Information Modeling) throughout all stages, from concept design and planning to construction, achieving both improved quality and sustainability. We created an accurate current model by 3D scanning the existing building, enabling high-precision design in a short period. Furthermore, VR-based design verification allowed for low-cost testing that simulated the feeling of being in a real space. Brainwave measurements also confirmed that the VR spatial experience closely resembled that of the real world.

・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 evaluate environmental impact, and verify effective CO₂ emission reduction measures. Through the use of BIM in this way, we integrate and manage each element of design, layout, construction, and environmental performance, realizing a space creation process that achieves a high level of balance between spatial quality and sustainability.
