YKK AP Inc. (Headquarters: Chiyoda-ku, Tokyo; President: Akira Uozu) is pleased to announce that the YKK AP30 Building (Kurobe City, Toyama Prefecture), which houses the headquarters for its manufacturing division and some corporate functions, has achieved 'ZEB' (*1) status—a building that achieves net-zero annual primary energy consumption—and the highest 'Platinum' rank in the 'WELL Building Standard™' (*2), an international evaluation system focused on the health and well-being of building occupants. To commemorate this, a completion plaque was installed on the building's premises in mid-March.
Completed in 2024, the YKK AP30 Building was designed with the concept of an "office in the forest," prioritizing the natural environment and the health and well-being of its employees. In November 2024, it received the highest 6-star rating in the BELS evaluation (*3) to achieve 'ZEB' status, and in November 2025, it attained the highest 'Platinum' rank in the 'WELL Certification,' a global standard that incorporates human health and happiness into building design and operation.
While 'ZEB' certification requires high building envelope insulation performance, 'WELL Certification' encourages the inclusion of openings to allow for natural light and views. Achieving both requires high insulation while still incorporating these openings. The YKK AP30 Building utilizes the company's own full-height building window system, 'SYSTEMA 31,' to create a bright and open space while maximizing the building's overall energy efficiency. This approach pursues both 'reduction of environmental impact' and a 'healthy and comfortable office,' leading to the attainment of the highest standards for both certifications.
It is said that "people spend 90% of their lives indoors" (*4). By optimizing the work environment, which occupies a large portion of that time, we have created a space where employees can perform at their best in a safe, secure, and comfortable setting.
