Alternative Bank Schweiz (ABS) is the ethical and ecological bank for people who like to know what is happening with their money. Alternative Bank Switzerland publishes all the loans it grants. This ensures that you know what your money achieves and even what good it does. ABS finances and invests in ecological and ethical projects and companies. It does not seek to maximise profits, focusing instead on sustainability and the ethical principles that this requires.
The Alternative Bank has operated as a savings and credit bank for some 20 years and currently caters to around 25,000 clients. Investments are made in accordance with ecological and ethical criteria. Sustainability is also an important topic in the Alternative Bank's day-to-day operations: for instance, the bank's headquarters are situated in a building which conforms to the highgrade Minergie P+ standard.The operation of the IT infrastructure therefore also aims to meet ecological and ethical criteria.
In 2007, the bank started outsourcing its IT operations to Swisscom. Swisscom runs the Finnova banking application in a professional manner and according to the highest require-ments in terms of security and reliability. The application is run on servers located in the Zollikofen data centre which are powered entirely by locally generated renewable energy, reducing the CO2 emissions produced by the data centre's operations by around 90%.Thanks to an optimised ventilation system and efficiency measures, the Zollikofen data centre saves around 4.5 million kilowatt-hours per year in comparison to previous generations of data centres, which equates to the energy consumption of around 1000 house-holds. Further considerable savings in energy consumption were also made by virtualising the servers that run Finnova. All of the servers in the Zollikofen data centre are virtualised, wIth the exception of two applications and a file server.The main focus for ensuring energy efficiency is ventilation, as the ventilation system alone uses a good third of the data centre's energy needs. Here, energy savings of up to 40 percent can be made. The Zollikofen data centre makes good use of the "free cooling" principle throughout the different seasons: In the summer, traditional cooling methods are used, whereas in the winter, the cold outside air is fed into the data centre. Green IT is more than just "hot air", particularly when air plays such a decisive role in saving energy.
One of Europe's most modern and efficient data centres is being built in the Business Park in Berne-Wankdorf. The new Swisscom data centre will set further benchmarks in the fields of energy efficiency and technology. The data centre will initially be equipped with a maximum of seven modules, each with an effective output of 600 kilowatts. The PUE (power usage efficiency) value achieves the top rating of 1.2 thanks to extremely efficient power usage. In comparison, the average PUE value for data centres in Europe is 1.95. This power usage enables Swisscom to reduce power loss by around 75 percent. Construc-tion work is expected to begin mid-2012.
The Alternative Bank can therefore achieve multiple goals at once:
