New ZEB operational technology reduces standard primary energy consumption by 115% in first year

TOKYO--(BUSINESS WIRE)--Mitsubishi Electric Corporation (TOKYO: 6503) announced today that its SUSTIE^� net zero-energy building (ZEB) test facility, which launched at the company�s Information Technology R&D Center (Kamakura, Kanagawa Prefecture) in 2020, reduced its energy consumption to less than 0%, meaning that it created more energy than it consumed, in its first full year of operation. The facility, a medium-sized office building with more than 6,000m² of floor space and equipped with solar panels, deployed ZEB operating technology to optimize operations, resulting in a 115% reduction in energy use compared to standard primary energy consumption as specified in Japan�s Building Energy Conservation Law (values differ according to region and building use). The results demonstrate that ZEB-level operation is possible even in dense urban areas while maintaining a highly comfortable and productive work environment.
