TOKYO, July 29, 2022 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that its "SUSTIE®" Net Zero Energy Test Facility has obtained Platinum-level WELL Building Standard™ certification, an international certification that evaluates the extent to which a building environment supports the wellbeing of its occupants.
It is expected that improvements to office environments will become more and more important in the future not only as a means of improving the health and productivity of employees but also as a factor when recruiting new staff. The SUSTIE facility has already received a top-level BELS 5-star rating (☆☆☆☆☆) and Net Zero Energy Building (ZEB) certification from the Building-Housing Energy-Efficiency Labeling System in Japan, and the highest level "S" rating from the CASBEE Wellness Office. These confirm that SUSTIE has achieved a high level of energy-saving and offers a comfortable working environment.
In addition to these recognitions, by being accorded Platinum status WELL certification-the highest level-SUSTIE has been certified to world standards as a building that enhances the health and comfort of its occupants. It is the first facility in Japan to obtain BELS, CASBEE Wellness Office, and WELL certification at the highest levels*.
In addition, in July 2021 SUSTIE has achieved the global standard WELL Health-Safety Rating™**, planned in response to the spread of the new coronavirus infection, certifying it as a facility that is managed and operated in a way that shows concern for people's health, safety and welfare.
Mitsubishi Electric will continue to pursue further improvements in the efficiency of building equipment and energy management, and in comfort and health levels, aiming to contribute to the development of a sustainable society in order to realize the ZEB+® concept, an approach the company is advocating that encourages the upgrading of buildings with facilities that promote productivity, comfort and convenience, and support business continuity.
