NOMURA Co.,Ltd. recruiting space "tokeru"

NOMURA Co.,Ltd., Ltd. has newly opened a conference room and waiting lounge space for recruitment interviews at Head Office building.
We anticipate that users will be feeling nervous when they visit this space, so we aimed to create a space where everyone can relax and perform at their best, as well as a space that would make interviewees think, "I want to work for NOMURA Co.,Ltd."

The two main challenges in this project were:
1) What kind of space would be appropriate as the face of the company, as it will be used for recruitment interviews and meetings with important clients?
②What kind of ideas can be used to complete the project within a tight schedule?

1) During recruitment interviews, we expect candidates 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 at their best.

The conference room uses curved glass that resembles melting ice, and the tables and sofas in the lounge are also rounded to create a visually soft feel. Normally, creating a conference room using glass panels can cause acoustic problems, but in this project, high-performance sound-absorbing panels were used on the ceiling and walls, eliminating these issues and creating a conference room with a soft impression created by the glass and lace curtains.

Indirect lighting is installed between the glass and lace curtains, and the light is dimmed to a level that allows silhouettes to be recognized but facial expressions to be imperceptible, creating a relaxed conference room where the atmosphere inside can be seen from the outside.

The lounge is fitted with a light wall that gives the impression of natural light changing over time. The refreshing, soft light visible through the curtains subtly complements the emotions felt while waiting for and after the interview.

②We have improved efficiency by consistently using BIM from concept design and working drawings to construction. Whereas previously we created mockups and measured their effectiveness, we have conducted various simulations using 3D models and quantified functionality, thereby reducing time while ensuring comfort.

By 3D scanning the existing building at the start of the design process, we were able to shorten the time required for on-site surveys and improve accuracy. VR was used to confirm the design, allowing for verification with the same sensation as real space at low cost. Electroencephalogram measurements also confirmed that the spatial experience in VR is similar to that of real space.

Additionally, because the conference room is surrounded by glass, there was a risk of sound reverberating, so we conducted acoustic simulations. By checking the sound absorption performance of the panels before designing, we were able to achieve the soft design of curved glass while also creating a space where reverberation is reduced and voices are easy to hear.

From an environmentally conscious perspective, BIM was used to calculate CO₂ emissions, and lighting and air conditioning simulations were performed to minimize power consumption and create a comfortable space. During construction stage, the process was visualized using animation, allowing all involved parties to intuitively and accurately understand the process.
