Reducing data center power consumption with Green Data Center service
NTT DATA launched a Green Data Center service in January 2008 to boost the benefits of ICT and reduce environmental impacts by improving server performance to reduce steeply rising data center power consumption and CO2 emissions.
In fiscal 2009, NTT DATA launched a Shared IT Platform Service to leverage virtualization and other technologies to provide high quality yet affordable shared ICT infrastructure where discrete systems were previously the norm. The company has also installed solar power generation and energy efficient air conditioning systems, and in January 2009 launched the first ever trial in Japan of a high voltage DC power supply system. NTT DATA aims to achieve further energy savings by expanding the use of high voltage DC power supply systems based on the results of this trial.

Monitoring services for visualization of energy use
NTT FACILITIES has provided Remoni, an energy monitoring service, since February 2009. Remoni, which was developed to support energy management in line with the revised Energy Conservation Law, enables the visualization of energy consumption at multiple locations.
Remoni is an application service provider (ASP) - based service that collects data such as cumulative and spot power consumption, temperature, humidity, and CO2 concentration from customer sites via the Internet.
This information can then be used for a wide range of applications such as energy management, environmental measurement, and remote monitoring of facilities.

Switching to biomass CD-ROMs
NTT West delivers software to customers of its remote support service via CDROM, and in January 2009, started using biomass-based ECO&B brand CDs produced by NTT NEOMEIT for some of these CD-ROMs.
ECO&B CDs require 25% less petroleum products to manufacture and produce 53% less CO2 emissions (total for both for manufacture and incineration) than do conventional CDs.

Eco-friendly GreenITy Buildings
NTT FACILITIES has leveraged its rich expertise to develop long-life, low impact GreenITy Buildings that efficiently combine various environmental technologies to reduce CO2 emissions by approximately 40% compared with conventional office buildings.

Customer server power consumption reduction
Nippon Information and Communication (NI+C) helps to reduce the power consumed by customers and society at large through offering server consolidation solutions that leverage virtualization technology to host multiple virtual servers on a single high-performance physical server. NI+C supplied 422 consolidated servers in fiscal 2009, resulting in energy savings of approximately 14 million kWh.
