Abeno Harukas

OSAKA 2014

In March 2014, Abeno Harukas, Japan’s tallest super high-rise towering 300 meters, celebrated its grand opening. Located over the Kintetsu Osaka Abenobashi Station, this multi-functional complex houses the train station, Kintetsu Department Store, an art museum, a hotel, offices and an observation deck.
Abeno Harukas can be divided into three zones: a department store on its lower levels; offices on mid-level floors; and a hotel on the upper floors. Pillar spans and ceiling heights were designed to optimize each specific function, while trusses were installed throughout the building to connect these frameworks. Dampers were installed to reduce building sway in the event of earthquakes or strong winds. Truss floors both link and segregate the three zones in the event of fire; they also serve as "eco-voids," providing passages for light and air. The exterior features aluminum curtain walls and float laminated glass, presenting a design that harmonizes with the surrounding cityscape.
The building incorporates a number of advanced environmental measures, including double-skin windows sandwiched with high thermal-insulation roll screens, and an energy management system (A-EMS) that visualizes energy use. Also implemented in Abeno Harukas is a newly developed biogas power-generation system that produces bio-gas from food scraps, which in turn are used to generate electricity and heat water.
The development and implementation of this bio-gas power-generation system won the 2013 Environment Minister’s Award for Global Warming Prevention Activity.
Abeno Harukas took six years to complete: located in a crowded downtown area, new construction methods such as the slide cover construction method were developed in order to overcome the challenging construction process.
