Toshiba Community Solutions Supporting People's Lives
Approaches toward Realization of Smart Society
Smart Communities Proceeding to Full-Fledged Implementation Stage

Smart communities have recently begun to reach the implementation stage after an investigation stage of about five years since their appearance as a concept. As a result of this trend, smart solutions to achieve effective utilization and conservation of energy have been expanding globally through technical and social verification and demonstration projects focusing on technologies for optimization on the demand side. On the other hand, smart solutions to improve the quality of community life, which are characterized by wide variations, are aimed at the development of technologies and services in cooperation with energy solutions and in line with community needs.
Toshiba is making efforts to realize a safe, secure, and comfortable society by integrating its proprietary technologies for social infrastructure systems and solutions with information and communication technologies (ICTs) including data management technologies.
Approach to Negawatt Aggregation in Yokohama Smart City Project

Surplus electricity obtained through power saving in response to the requirements of a power company or other reasons, known as negawatt power, has been attracting attention as a countermeasure against the tight balance between electricity supply and demand since the Great East Japan Earthquake. In this context, the Ministry of Economy, Trade and Industry (METI) is currently working on the development of a system related to negawatt dealings through the Electricity System Reform process.
As part of the Yokohama Smart City Project, which is testing a wide-area energy management and demand response (DR) system involving households, buildings, facilities, and electric vehicles, Toshiba has conducted demonstration experiments aimed at realizing stable negawatt aggregation using a clustered building energy management system (BEMS) as an aggregator. Experiments on the creation of negawatts through the planning and implementation of power reduction targets consistent with the margins for each building comprising a group of buildings confirmed that an average of more than 90% of the targeted power reduction was achieved.
Toshiba's Approaches to Miyakojima City All-Islands EMS Demonstration Project to Actualize Island Type Low-Carbon Society
OGITA Yoshihiro / OGAKI Yuji
With the goal of constructing an island type low-carbon society system, Miyakojima City in Okinawa Prefecture is promoting the Miyakojima City All-Islands Energy Management System (EMS) Demonstration Project over a four-year period that commenced in FY2011. The objective of this project is not only to achieve energy saving, but also to attain commercialization through energy management balancing demand and supply in the area energy network.
Toshiba was selected as a system constructor for this project and is engaged in the development of the demonstration system as well as demonstration and evaluation activities. Based on the knowledge accumulated through this project in Miyakojima City, we are aiming to provide an island type model as a regional solution to remote islands in Japan and other countries in order to solve issues inherent to such areas.
Promotion of Smart Community Demonstration Project in Lyon, France

Toshiba and Toshiba Solutions Corporation have been selected by the New Energy and Industrial Technology Development Organization (NEDO) as lead contractors for a smart community project in the Lyon Confluence redevelopment district, France. We are now engaged in introducing the main equipment and systems for this project and conducting verification tests.
The objective of this project is to achieve sustained growth of the redevelopment district by applying a number of sophisticated technologies related to energy solutions, developed not only by the Toshiba Group but by other Japanese companies as well, to buildings and traffic systems in the district. These technologies include several energy management systems (EMSs) to support smart energy utilization by users; models for the local production and consumption of renewable energy, such as electric vehicle (EV) charging using photovoltaic (PV) systems; and a community management system (CMS) supporting city planning.
Verification of Energy-Saving Effect Achieved by Model-Based Air-Conditioning Control Function of "Smart BEMS"
TAMARU Shingo / ASAZUMA Tomohiro
Toshiba has developed "Smart BEMS," which provides the optimal building energy management system (BEMS) technology through integrated management of each building facility. Smart BEMS makes it possible not only to achieve high levels of comfort and energy saving but also to maintain building functions by making full use of limited electricity supplies in the event of a disaster.
Model-based air-conditioning control, which is one of the functions of Smart BEMS, can reduce the energy consumption of heat-source and air-conditioning systems while maintaining comfort. We have conducted demonstration tests at the Smart Community Center, the base for Toshiba's smart community business, and confirmed that the model-based air-conditioning control function can reduce the energy consumption of heat-source and air-conditioning systems by an average of 13.1% and 8.6% in the winter and summer seasons, respectively, compared with a system that is not equipped with model-based air-conditioning control, without sacrificing comfort.
Toshiba Smart Home Aimed at Realizing Safe, Secure, and Comfortable Lives of Residents
MATSUE Kiyotaka / EDAHIRO Toshiaki
Toshiba has constructed the Toshiba Smart Home, an interactive exhibition facility and demonstration facility that began operation on October 2, 2014, at its Fuchu Complex. The Toshiba Smart Home is playing an important role in our research and development activities to verify a comfortable indoor environment and energy optimization through the introduction of new energy equipment including a photovoltaic power generation system, a fuel cell system, and a storage battery system; the latest home appliances controlled by a home energy management system (HEMS), and a showroom offering customers a hands-on experience of new products and services.
To create a safe, secure, and comfortable society, we are introducing various cutting-edge technologies and services into well-sealed and heat-insulated houses aimed at enhancing people's lives taking sustainability, diverse values, and healthcare into consideration.
