Kiwibank deploys NightWatchman and stands to save thousands in PC energy costs

Sustainability is at the heart of Kiwibank’s business. Basic energy meters were predicting that more than 50% of computers were being left on at nights and weekends at the New Zealand bank. The cost and energy savings associated with PC power management were very attractive and fit into the wider corporate sustainability goals at Kiwibank.

The bank needed a solution to monitor and reduce computer energy consumption without disrupting users. It also needed to wake computers up out of business hours to patch them. A key requirement was to find a solution that integrated with Kiwibank’s existing Microsoft System Center Configuration Manager (SCCM) platform.

“Educating employees to switch computers off was one option but IT often needed computers to be left on so that patches and security updates could be applied at night rather than during working hours,” says Esme Petelo, Head of IT Management Support, Kiwibank.

There was also a desire to measure IT energy use on an ongoing basis rather than relying on guess work so a decision was made to trial NightWatchman an advanced PC power management solution from 1E.

Kiwibank wanted the ability to centrally control and report on the power consumption of computers across Kiwibank’s entire IT estate. NightWatchman was chosen for a number of reasons; the solution was proven in large-scale environments and integrated seamlessly with Kiwibank’s existing Microsoft System Center Configuration Management (SCCM) system. NightWatchman was also easily available through 1E’s preferred New Zealand based distributor, Transend.

Transend installed NightWatchman across a representative sample of computers. Data was collected over a four week period in order to benchmark PC energy consumption. The weekday behavior report built into NightWatchman showed that during this baseline period, 52% of computers were left on overnight. Over the weekends 50% of computers were left on – with only 9% being used.

Setting a baseline of average computer energy use will enable Kiwibank to take accurate measurements over time. The bank will be able to compare results and see the savings they are making as well as identify any areas for potential improvement clearly.

Additionally, Kiwibank sought funding by applying for an Energy Efficiency and Conservation Authority (EECA) technology grant. As part of the grant application process, EECA commissioned a third-party verification of the projected energy, cost and CO2 emissions savings that Kiwibank stood to make following the deployment of the NightWatchman project. This independent verification, conducted by Energy and Technical Services Ltd confirmed that Kiwibank would save approximately NZ$27.32 (US$23.47) per computer per year.
