Mitsubishi Electric Facility Receives Net Zero Energy Building Certification
First medium-scale office building to be certified in Japan while still under construction
TOKYO, August 7, 2019 – Mitsubishi Electric Corporation (TOKYO: 6503) announced today that its
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 theBuilding 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 tostart operating in September 2020.
Mitsubishi Electric is promoting technical developments based on its ZEB+ concept of constructing andupgrading buildings over their lifecycles for environmental efficiency, energy savings, productivity, comfort,convenience and business continuity.

BELS certificate

The certification recognizes the facility’s projected reduction in energy consumption by 103% (includesproduction of photovoltaic energy) compared with its surrounding region’s average consumption levels,
measuring total energy consumption for air conditioning, ventilation, hot water, lighting and elevators basedon energy conservation standards introduced by Japan’s National Institute for Land and InfrastructureManagement in 2016. To qualify for certification, Mitsubishi Electric optimized design conditions for theentire construction process, maximized the efficiency of equipment and systems to be installed in the facility
and introduced ZEB-based solutions for air conditioning, lighting and photovoltaic systems.
Mitsubishi Electric expects the global ZEB market to expand to 40 trillion yen by 2030 and Japanese market
to expand to 130 billion yen by 2020 and 630 billion yen by 2030.
Mitsubishi Electric registered with the Ministry of Economy, Trade and Industry as an official ZEB planner in2017. Going forward, the company aims to accelerate its development and application of ZEB-related
technologies to contribute to the achievement of the United Nations Sustainable Development Goals and therealization of greater energy savings and more comfortable living spaces, as well as contribute to moreconvenient office environments under its proprietary ZEB+ concept.
