Increase of Comfort

In order to maintain good air quality and hygiene in offices and hygiene in offices and improve the health and productivity of users, indoor environment monitoring based on tenant satisfaction surveys is carried out for ensuring that offices are always comfortable.

In NBF's capital investment decision making process, the status of the building's compliance with the Barrier-Free Law, accessibility for people with disabilities, accessibility to public transportation around the property, etc. are mandatory items to be confirmed. These items are periodically confirmed through engineering reports and other documents obtained during the consideration stage and post-investment monitoring phases, and if there are issues or room for improvement, specific measures are discussed during the operation stage. Through these inclusive efforts, we aim to provide a building that is comfortable for all office users.
