Kofu City Hall

The site is located in central Kofu within walking distance of Kofu Station, Yamanashi Prefectural Offices, Maizuru Castle Park and the commercial district.
The new City Hall opens out to the neighborhood, actively welcoming citizens.
The city hall also is the focus for a new pedestrian network safe and full of greenery to create a "Town for Walking".

As the city receiving the most solar radiation in Japan, the City Hall is covered by a 3000kW solar power system designed to emulate the grape trellis fields that dominate the beautiful scenery of Kofu Basin.
Other ecological technologies such as rainwater collection, heat retrieval piping/heat-cool trenches geothermal system and natural ventilation system integrating the courtyard and ventilation voids, are employed throughout in the building. The live digital display shows visitors the systems in action and actual energy production in real time. The City Hall has now acquired the popular nickname "Grape Trellis Hall".
