Gestione energetica del nuovo data center di Ingolstadt Gestore: Audi AG Obiettivo: Corporate data center Nazione: Germania At its headquarters in Ingolstadt Technical Development currently gets a new business card: The "Forum simultaneous engineering" in the future, 450 employees spread over eight floors, to the cars of the future work. Already in mid-2012 in the cellar of over 70 million euro construction suggests the IT heart of the company: see in two basement levels on a 2000 square meter floor space up to 6000 server space. All essential IT services for the approximately 51,000 computer users at Audi are made available from there. Due to the low temperatures in the basement, Audi achieved significantly more efficient than previously in its three data centers in Ingolstadt. On energy-intensive compressors shall be omitted entirely. For an indirect free cooling, the outside air is tapped from only twelve degrees ambient temperature. The aim of the annual energy consumption could be reduced by about a third. Given the impending climate change surely this post is important. But green IT could make much more than show the actual examples in the automotive industry. "Although green IT has for years been on the agenda, ranging previous efforts in the sum of not even begin to compensate for the continually increasing IT-related energy consumption. We are still at the very beginning, "said Thomas Chiefs, the initiator of the" Green IT Best Practice Award "at this year's awards ceremony late November 2011. And he's right: In order to achieve real success, the focus should rather be on one driven by information technology resource efficiency. Which, however, requires a more forceful rethinking. And not only the CIOs. The new building is an important step towards CO2 reduction in IT. We will "reduce our annual energy consumption from 2012 to at least a third, says Klaus Straub, Chief Information Officer (CIO) at AUDI AG. 2009, the energy consumption of the current three data centers in Ingolstadt was at 17 million kWh. Equivalent to the annual energy consumption of 4,250 single-family homes with an average consumption of 4,000 kWh. Audi relies on "Green IT", a holistic approach to reducing energy consumption and reduce CO2 emissions in IT. Also contributes to the placement of the new data center in two basement levels. Because it is much cooler in the basement, the energy-intensive chillers for cooling the server with a much better efficiency can be operated. The new building is the so-called "indirect free cooling" system. According to this principle as early as 12 degrees ambient temperature is cooled by outside air. "The issue of cooling is very important. Here we see a potential savings of 50 percent of energy, "said Straub. Among the technical equipment for the new Audi relies on devices with high efficiency and low energy loss, such as loss-free transformers. As a buffer for uninterrupted power supply instead of the previously used energy-efficient flywheel energy storage batteries are used, the also have a four times longer than conventional lead-acid batteries. Together with the entire SE forum scheduled for 1 July 2012 go the new data center with about 9,000 square meters, after three years of construction. Available Documents Audi SE-Forum

Data Center (RZ-CDC) Ingolstadt In questa nuova sede saranno riunite diverse divisioni per dare il “calcio d’inizio” al processo del prodotto e per la gestione dell’ingegnerizzazione simultanea dei progetti per i veicoli futuri dell’intera Audi AG. Il forum, integrato nel SE-RZ, è basato su "Green IT", un approccio integrale per la riduzione sia del consumo energetico, che per la riduzione delle emissioni di CO2 nell’industria dell’IT. Dati Inizio della costruzione: Agosto 2009 Fine della costruzione: Settembre 2012 2000 m² di superficie, su due piani Spazio per 6000 server per 51,000 computer utente Specifiche dell’edificio Edificio a 10 piani BRI 119.000 m³ BGF 34.000 m²

Esigenze per la gestione energetica La conservazione delle risorse e la sostenibilità degli edifici, per Audi è tanto importante quanto l’industria dell’auto. L’utilizzo efficiente dell’energia è caratterizzato da edifici a bilancio neutro di CO2 da location a zero emissioni di CO2, come Ingolstadt.
