Fujitsu and Nippon Koei Partner to Develop IoT Energy-efficiency Service for In-house Server Rooms

Focus on Energy Consumption Prompted by Steady Rise in Domestic Electricity Prices

Domestic electricity charges have been steadily rising ever since the Great East Japan Earthquake & Tsunami in March 2011, and private industry is increasingly exploring ways to minimize energy consumption and reduce power bills. A popular strategy is peak shifting, where the operation of lighting, heating and cooling systems and production machinery and equipment is shifted back or forward in time to take advantage of cheaper electricity tariffs. A prime target for reducing power consumption is the in-house server room, which generates significant energy demand. Industry is also looking into EMS* solutions as a means of satisfying stricter environmental regulations and engaging government subsidies.

* EMS = Energy Management System, used to monitor consumption of electricity, gas and other forms of energy and design energy-saving strategies

Ongoing Assistance in Reducing In-house Server Room Energy Consumption

Fujitsu has teamed up with construction consulting firm Nippon Koei to develop a domestic IoT based energy minimization solution for in-house server rooms. The partnership agreement covers the following:

1. Supplying IoT services that harness the strengths of both parties
2. Providing ongoing support for energy minimization strategies for in-house server rooms

Under the terms of the development agreement, Fujitsu will supply the cloud-based EMS service Intelligent Society Solution Enetune-BEMS, which enables remote monitoring of building energy consumption levels and the operational status of heating, cooling and lighting systems. Fujitsu technology will be complemented and augmented by the extensive expertise and experience of Nippon Koei in the area of building modifications and energy-saving systems and strategies. The combined expertise of Fujitsu and Nippon Koei will be used to provide a comprehensive suite of services to help clients reduce their energy consumption levels, from monitoring server room power consumption levels to consulting on energy reduction strategies, equipment installation, and assistance with applications for government subsidies.

Prior to launching the service, Fujitsu conducted trials at its own in-house server room. The results showed a 27% reduction in the energy used to feed heated or cooled air through the system.

The official launch is in October 2015. Fujitsu and Nippon Koei plan to adapt the service to other scenarios such as office buildings and distribution outlets.
