With the development and popularization of computer and network technology, IDC, as a unit with lots of computers and networks centralized installation and operation, has become an independent industry with a complete business model. Because in the IDC, there were thousands of computers running in a sealed environment, cost of power consumption of IT equipments and cooling air conductions accounted for more than 50% of total operation cost of the IDC. Andthe huge power consumption limited scale of the IDC construction. So a green energy saving machine room has become an inevitable choice for today’s IDC. At present, most of reducing power consumption measures are taken to external facilities, but not to servers which are a major part of the power consumption. The paper proposed a complete IDC solution based on reducing the server power consumption, solar main power supply and optimizing distribution system. Thenthe article discussed its principle and proposed Irene technical standards and Irene room construction specifications. Finally the green performance was validated through testing results and commissioning situation.
