LONDON, United Kingdom — Construction and project-management firm Bovis Lend Lease announced today that, 10 months after installing 1e's Nightwatchman software, it was already one-third of the way to achieving its corporate-wide energy efficiency goals.

Putting the PC power management software to work on 3,000 computers in its European fleet, Bovis was able to reduce its energy consumption by over 90,000 kilowatt-hours, 32 percent of the way to its total goal of 278,500 kWh in reductions.

The PC power management project is one of several sustainability goals Bovis Lend Lease put in place at the end of 2007. The overarching target is to reduce the firm's greenhouse gas emissions by 20 percent over a three-year period.

A big part of that target involved cutting emissions from its offices, which are responsible for 2 percent of the company's overall carbon footprint. Using 1e's Nightwatchman software put Bovis Lend Lease well on its way to achieving that goal.

"We are always looking for innovations like NightWatchman from 1E that could bring our carbon base load to a lower level," Paul Toyne, the head of sustainability at Bovis Lend Lease, said in a statement. "The reduction in energy cost that we have seen from deploying NightWatchman onto just 3,000 of our desktops is a saving we expect to make year on year -- and there's potential for even more savings when we realize the impact from our global roll out of the solution out our entire PC estate."

1e has long been a player in the PC power management field; last fall, the company introduced a 'drowsy computing' system for data center management, a server-focused addition to its Nightwatchman lineup that lets data center managers to put their servers in the most energy-efficient states when conducting backups or other non-mission-critical tasks. Drowsy servers can cut energy use by 12 percent with no reduction in performance, 1e said in an interview last year.

The U.K. government found power management to be a successful strategy for cutting costs and carbon emissions across the government, according to a report released last September.

Other firms working in the power management space include Verdiem, which last August announced that it had hit the million-user mark for its Surveyor software; and BigFix, which signed on 25,000 university computers last September for its own power management software.
