Arup saves a third of PC energy costs each year with NightWatchman

NightWatchman from 1E provides the enterprise with total control over the entire PC estate, 24 hours a day with unrivalled PC Power Management and Patch Management.

Arup first came to the world’s attention with the structural design of the Sydney Opera House, followed by its work on the Centre Pompidou in Paris. Arup has since grown into a truly multidisciplinary organization. Its work for the 2008 Olympics in Beijing reaffirmed its reputation for delivering innovative and sustainable designs that reinvent the built environment.

Arup always encouraged staff to switch off their computers each evening before leaving the office. However, this was hard to manage as it was not an automated process. This challenge, the global increase in energy costs and the growing need for greater awareness of its carbon footprint the UK, Middle East and Europe, led Arup to evaluate a number of power management solutions for its fleet of desktop computers. After a competitive tender and a number of trials, it selected 1E’s PC power management solution, NightWatchman.

The initial implementation of NightWatchman took two analysts just three days to test and make live. A four-month baseline test was run so that the structural engineering firm could get a view of both its energy cost and CO2 emissions; this was carried out with no communication to either the end users or IT staff at Arup, so as not to influence or change behaviour. The resulting data from this showed that on average 25 percent of computers were being left on each weekday evening and 20 percent each weekend.

It was agreed that PCs would be scheduled for shutdown at 7:00 p.m. each night, using NightWatchman. However, with the process firmly in place, the need for flexibility was still paramount. In these instances, NightWatchman can be configured for program exceptions – automatically applied via Group Policies – so effectively, if the 3dmax.exe process is running on a computer during the 7:00 p.m. shutdown window, the shutdown will be aborted, leaving the machine on and the application able to complete its task.

With 99% of Arup’s desktop fleet in UK, Middle East and Europe now being powered down each night, the region is saving approximately 442 metric tonnes of CO2 per year.

“The solution set was the obvious choice because it is widely recognized as industry-leading,” comments Richard Barnes, Associate and Automation Team Leader, Arup. “We saw that a number of blue chip organizations, including Dell, were investing in the products due to the unique data analysis features; its integration into Microsoft’s System Center Configuration Manager; (Arup’s preferred system for software and operating system deployment) and its unique ability to wake up and shutdown computers en masse, without impacting end-user productivity. The two products also provide the flexibility to manage software patches and updates across the enterprise network in a less intrusive, more effective manner – the combination of these factors sealed the deal.”
