Mitsubishi Electric Facility Receives Net-Zero Energy Building Certification
TOKYO — Mitsubishi Electric Corp.’s envisioned Net-Zero Energy Building Test Facility has become Japan’s first medium-scale (over 6,000 m2) office building under construction to receive a top-level BELS 5-star rating and Net-Zero Energy Building (ZEB) certification from the Building-Housing Energy-efficiency Labeling System, a third-party certification organization in Japan. The rating, which measures energy-saving performance based on the Building Energy Index (BEI), is for the building’s theoretical performance levels.
Mitsubishi Electric is constructing the Net Zero Energy Building Test Facility in Kamakura, Kanagawa Prefecture, south of Tokyo, to develop and demonstrate ZEB-related technology. The facility is scheduled to start operating in September 2020.
