MATSUZAWA Shigeo / HAGIWARA Kazunori
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.

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.

Handwriting Retrieval Technology for Tablets with Pen Input
SHIBATA Tomoyuki / TONOUCHI Yojiro / NAKAI Tomohiro
The wide dissemination of smartphones and tablets with pen input has provided users with the capability to easily store handwritten data as digital data. Accompanying the increase in such stored data, demand has arisen for a technology to rapidly extract the necessary information from large volumes of handwritten data.
To meet this demand, Toshiba has developed a handwriting retrieval technology that can retrieve targeted handwritten data, including not only words but symbols as well, through recognition of the stroke order and shape of strokes without the need for information on the language in which the characters are written such as Japanese or English. This technology, which operates at high speed with a small amount of memory usage, has been incorporated into the AT703 REGZA tablet.
