Cooperative Installation of Architecture and New Technologies to Realize Smart Buildings


July 19, 2011IBM Japan Ltd.Takenaka Corporation

IBM Japan Ltd. (President: Takayuki Hashimoto, NYSE: IBM) and Takenaka Corporation (President: Toichi Takenaka) have cooperatively installed architecture and new technologies to create Smart Buildings, which are capable of sharply reducing electric power consumption below that of normal office buildings without harming the comfort in the offices, in Takenaka Corporation’s affiliate, TAK E-HVAC’s Shinsuna Headquarters Building (Koto-ku in Tokyo, below, “TAK Shinsuna Bldg.”).

In past buildings, control systems for air conditioning, lighting, etc. have applied separate control methods of each device maker, preventing integrated control of lighting or air-conditioning devices made by different makers. Building Energy Management Systems (BEMS), which manage all building equipment, energy, etc. in large-scale buildings, etc., were installed independently in each building, so it was difficult to perform integrated control of the equipment, energy, etc. in multiple buildings.

Having undertaken a next-generation energy-conservation etc. architectural system proving project as a project subsidized by the New Energy and Industrial Technology Development Organization (NEDO)Takenaka Corporation has, developed technology to minimize energy consumption while performing integrated control of air conditioning, lighting, and various sensors from different manufacturers to increase intellectual productivity and maintain comfort.Takenaka has further proven the effectiveness of this new technology by installing it in the TAK Shinsuna Bldg. IBM Japan Ltd. The company has also developed a regional energy management system through a regional energy management system development project of the Ministry of Economy, Trade and Industry, and it has proven this system at the Kitakyushu Smart Community, and using a regional common platform on the Cloud.A working infrastructure for a variety of services including energy management for administrators, corporations, and homes, etc.has also been established.

IBM Japan Ltd.’s regional common platform on the Cloud has been successfully linked to the Takenaka’s next-generation equipment control system. This means it is now possible to perform integrated control of diverse equipment and devices in multiple buildings, permitting unified control of air conditioning, lighting, etc. in multiple buildings scattered throughout the country by, for example, automatically judging conditions such as each region’s weather, time period, or state of use.

Thanks to this new technology, it is now possible to develop various kinds of control systems applicable to any building based on open specifications enacted under OSGi (). This means that it is easy to add or renew control systems, so that energy management, security management, and other services can be advanced and diversified and their cost reduced.

Takenaka Corporation will aggressively propose the equipment control system actually installed at TAK Shinsuna Bldg. as a type suitable for next-generation office buildings which will be constructed in the future. IBM Japan, Inc. will promote the use of this system by supporting the provision of services to construct the regional energy management system which it utilizes.

The two companies will continue to apply the architecture and new technologies in order to encourage the construction of Smart Buildings.

OSGi: OSGi (Open Services Gateway initiative) Alliance, a standardization group established in March 1999. It defines service platforms for Java which permits control from remote locations.
