YKK Fudosan Co., Ltd. (Head office: 1, Kanda Izumi-cho, Chiyoda-ku, Tokyo) was awarded the top prize (first place) at the global level in the ASHRAE Technology Awards*1 for its YKK80 Building. The competition is sponsored by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE*2). The YKK80 Building is the head office of YKK and YKK AP and is the first Japanese building to receive the award.

YKK80 Building Awarded ASHRAE AwardThe ASHRAE Technology Awards are held among 14 regions, which include locations in the U.S.A. and around the world. The top buildings in each region are nominated for the global level awards. YKK80 Building was the first Japanese building to be selected as top prize winner in the Asia region, progressing to the global level awards, where it also received top marks.

In February 2016, YKK80 Building received a LEED-CS “Platinum” rating from the U.S. Green Building Council (USGBC) – the developers and operators of the LEED certification process. This was the first time that an office building in Japan has achieved this rating. Moreover, in August 2016, the building earned the top, five-star ranking from Japan’s BELS labeling system. The receipt of this Global Level ASHRAE Technology Award reaffirms the world-class level of YKK80 Building’s energy-saving performance and environmentally-friendly construction.

Consideration for the environment will continue to play an important role in our ongoing management and business activities.
