What is environment-oriented management?
It refers to the activities in which corporations invest resources on mitigation of environmental burden, understand costs spent on
environmental activities and widely announce their activity status. Further, it refers to the management targeted for sustainable
development with integrating environmental commitments in the management policy
(1) Determination and announcement of costs for environmental activities
(2) Commitments to environment preservation

Approach 1-High voltage DC power feed (HVDC)
Why is the importance of high voltage DC power feed emphasized now?
Compared to conventional AC power feed, it reduces energy loss based on less frequency of conversion as well as some other expected advantages.

Note: Aisle capping “Aisle capping” is a registered trademark of NTT Facilities Corporation. The product includes patented invention of NTT Facilities Corporation.
Aisle capping equipment integrating antiAisle capping equipment integrating anti--seismic elementseismic element
Overview
Rack configuration where suction side of machine is directed to closed space. By limiting cooling space to the closed space, more efficient cooling can be achieved (30% reduction in power consumption by air conditioning)
Integration of server rack and anti- seismic element. Minimum earthquake impact on server rack.
Approach 3-High efficiency AC design
Why should efficiency of air conditioning be improved?
Increased cooling performance is requested due to heat generation and high integration of high performance servers. Power consumption by air conditioning is extraordinary high. In the current approach, anti-seismic elements are installed to minimize earthquake impact on server rack in the buildings without anti-seismic countermeasure.
