Nishiki 2

Nishiki 2 District is a textile wholesaler district in transition located in the high-density urban center of Nagoya City, Japan.  The district is designated as commercial zone with the floor area ratio of 600% or 800%. Actual land use is a mix of offices, retailers, wholesalers, restaurants, bars, cafes, parking lots and limited residential units.  The building stock is a mix of old buildings built after the World War II and newer re-built or re-developed buildings. The streets occupy around 40% of the district.  

Low-carbon projects are currently conducted by the project teams in the Nishiki 2 Community Development Council.  The roadmap of community-led low-carbon projects in the fields of buildings, transport, logistics, urban environment and energy systems aims to achieve 44% reduction of CO2 emission per person.  On the other hand, 0.5 ha commercial and residential mixed-use urban redevelopment project is underway in Block 7 by Nishiki 2 District Block 7 Urban Redevelopment Union. The project will contribute to support community-led low-carbon projects while reducing CO2 emission by itself.

Context

Intensive community visioning process for 2030, resulting in the publication of the Nishiki 2 Community Development Vision 2011-2030, were conducted from 2008 to 2011, followed by the implementation of several community-led projects.  Research on design and implementation of low-carbon blocks conducted by researchers at Nagoya University has helped the community council to focus on low-carbon projects and apply for Nagoya City’s Low-Carbon Model District.

Sustainable Development

Nishiki 2 Community Development Vision 2011-2030 is structured around the goals of “secure living”, “vibrant economy” and “culture of coexistence” corresponding to the three pillars of sustainability.  The projects are conducted by various actors who respect this vision. Low-Carbon Community Development Project further promotes the reduction of CO2 emission through community-led projects. The project is conducted by the four steps “developmental circulation process”.  The first step is “stakeholder involvement”, a step to form a team by collaborating with necessary persons and organizations to implement the project. The second step is “project organization”, a step to compose the project contents and divide the roles. The third step is “project implementation”, a step when actions are taken after planning and coordination.  The fourth is “learning and feedback”, a step for the stakeholders to learn the lessons, issues and impacts of the project and give feedback to the previous steps. This participatory, iterative process is contributing to the sustainable promotion of urban regeneration.
