Smart City Project in Chiba, Japan, Gets Full-Scale Launch

Keywords: Environmental Technology Government Non-manufacturing industry Renewable Energy 

An integrated redevelopment of Block 148 in front of the Kashiwanoha Campus Station in Kashiwa, Chiba Prefecture, is in full swing toward its final completion in spring 2014. This is a key part of the ongoing Kashiwanoha Smart City Project spearheaded by Mitsui Fudosan Co., a major Japanese real estate company. The company took a comprehensive approach in developing the project in order to create a local energy optimizing control and resource recycling system, in cooperation with leading companies in the environmental field, universities, and municipalities.

Block 148 is composed of a hotel/residential building and a commercial/office building. Aiming at thorough utilization of the city's unused energy in these buildings, the company plans to harness 200 kilowatts of solar power generation, augmented by gas-fired power generation, kitchen garbage biomass power generation, and an air-conditioning and hot water supply system using exhaust heat when power is generated, as well as geothermal and solar heat. The multiple energy sources can provide 60 percent of the normal power supply even in the event of a power outage.

Around the station, including Block 148, energy management systems (EMSs) installed in each building are integrated into an area energy management system (AEMS) developed to control centrally the amounts of power generated locally, power coming in from outside sources, and power consumed. The company also plans to provide energy-visualization and information-sharing tools for the entire area.

The project was selected by the Ministry of Land, Infrastructure, Transport and Tourism as one of its fiscal 2010 Model Projects Promoting Low CO2 Emissions for Houses & Buildings. It is projected that the entire Block 148 will be able to reduce its carbon dioxide emissions by approximately 40 percent.
