Building communications system: Takenaka´s M2M platform for building management & application interface

In this presentation, we will introduces Takenaka Corporatin\´s Machine to Machine(M2M) communications platform for building management. With it\´s system architecture and some implementation case studies, including energy data visualization, demand response, and utilization of building information modeling (BIM) data at building operation. While conventional buildings have been practicing various energy saving and building management measures by each building individually, the recent innovation of Information and Communication Technologies (ICT) proposes valuable solutions by enabling interconnection between building systems and miscellaneous devices, such as end-use appliances, mobile phones, automotive, and power grid. To enhance synergy of state-of-the-art ICT and building engineering, Takenaka Corporation has developed an open-source, multi-connection, extensible information and control platform, called "Building Communications System". Takenaka Corporation is one of the largest planners, architects, engineers and contractors firm in Japan, with yearly sales of $9 billion, 20 overseas offices, the largest construction R&D laboratory in the world. One of the field of researches is building environment and energy management, including building control systems and strategies, net-zero energy buildings, and smart community.
