The City of Yokohama is working together with private companies and citizens to promote “Yokohama Smart City Project” as one of the Ministry of Economy, Trade and Industry's “Next-Generation Energy and Social System Demonstration Projects.” With the goal of realizing a low-carbon city, the Project applies smart grid, electric vehicle and other cutting-edge technologies in a comprehensive social system from the energy supplier side to the energy demand side to demonstrate new urban management forms.
The Mitsui Fudosan Group participates in the “Yokohama Smart City Project” demonstration project at “Yokohama Mitsui Building,” “Park Homes Okurayama” and “Fine Court Okurayama Masters Hill.”

The Mitsui Fudosan Group participates in also the City of Fujisawa's “Fujisawa Sustainable Smart Town Project,” promoting land readjustment projects and supporting projects on the whole.
“Yokohama Mitsui Building” is a highly-environmental office building that has obtained certification of the highest rank S under CASBEE Yokohama. Drawing on such high environmental performance, Mitsui Fudosan joins hands with Toshiba Corporation, Marubeni Corporation and Mitsubishi Estate Co., Ltd. to implement a demonstration project for considering the ideal form of “office building electric power supply-demand demand response” for the first time in Japan as a part of the “Development and Demonstration of the Groups of Buildings Management Center” of the “Yokohama Smart City Project” (period: autumn 2012 to fiscal 2014).
Each building's Building Energy Management System (BEMS) will be linked to the Integrated Building Energy Management System (Integrated BEMS) developed and operated by Toshiba. This will enable the status of use of energy, etc. to be confirmed for each building and for each floor.
Furthermore, based on demand management of electric power energy from the Community Energy Management System (CEMS), a framework for adjusting usage depending on the status of use of electric power at each building will be considered.
At Mitsui Fudosan Residential Co., Ltd.'s “Park Homes Okurayama,” too, a project for demonstration of the “Mansion Energy Management System” for large-scale for-sale condominiums will be implemented from late December 2012 to fiscal 2014.
