Energy-saving Measures
Chart of Organizations Tackling the Global Warming Problem
Within Topic-Based Promotion Sub-groups, in which the NEC Group companies also participate, four meeting bodies are installed to discuss global warming measures. The Topic-Based Promotion Sub-groups report and propose to the Environmental Management Promotion Council, which promotes anti-global warming measures in general, to implement energy-saving measures by the entire NEC Group.
Activities at Each Plant
NEC plants
Triggered by enforcement of the Tokyo Metropolitan Environmental Security Ordinance by Tokyo Metropolitan Government and Law concerning the Rational Use of Energy, the energy-saving solution "enepal PC" that uses ICT has been installed in office computers.
Tamagawa plant
The Tamagawa Solution Center has achieved a CO2 emissions reduction of 50% compared to conventional offices through the use of ICT and energy-saving facility systems.
Fuchu plants
The Fuchu Plant’s near-top-level certification was renewed in the certification system for global warming mitigation top-level facilities based on the Tokyo Metropolitan Environment Protection Ordinance. A variety of initiatives are being carried out to reduce CO2 emissions.
Upgrade to high reflection 1-Light Hf light fixtures
Upgrades made in FY 2010 and 2011 were continued in the first half of FY 2012, with approximately 2,350 fixtures upgraded, for a total of 8,850 fixtures installed.
Upgrade of machine room air-conditioning
Upgrades were made from an individual water cooled packaged air conditioning system to a central heat source and fan coil unit air-conditioning system. Through employment of the cooling function using outside air during winter (free cooling), CO2 emissions are expected to be cut by 39% compared to conventional methods.
