This building was designed to house the Head Office functions
of Kansai Electric Power Company. Built as Phase I of the
“Nakanoshima 3-Chome Joint Development Project”.
One of the basic concepts for this building is a "model building for environmental symbiosis". In areas around windows, the outer frames (columns, beams) protrude by about 1.8m outwards from the window surface. This not only constitutes a shaded exterior but also provides functions such as a natural light intake from the large window surfaces, shielding of sunlight by the canopy, introduction of natural ventilation via the eaves, and space for installation of solar panels. Besides these, we have also introduced a task-ambient air conditioning system, internal heat storage and other technology for environmental symbiosis.
The building also features a “communication well” (a three-floor atrium in the high-floor office zone), the aim of which is to communicate widely.
