office pcs webEnterprise energy cost reduction without impact on business.

Computers are one of the fastest growing electrical loads in the business world. Each year more and more computers are purchased and put to use. But it’s not just the number of computers which is driving energy consumption upward. The way that we use computers also adds to the increasing energy burden.

Research reveals that most personal desktop computers are not being used the majority of the time they are running and many personal computers worldwide are needlessly left on continuously.

An intelligent and balanced energy management is mandatory from the ecologic and financial point of view for every serious Enterprise today.

With a growing number of computerized working placed as well as rising costs for energy the expenses for power are increasing dramatically. Additionally other cost centers are indirectly impacted as well- such as air conditioning – just to reduce the additionally produced heat by computers..

Following an article from "The Register", discovered that energy costs could be reduced by up to 80% if PCs just simply would be shut down after work end and during weekend.

[…Short-term efforts are focused on energy saving with computer installations. At a simple housekeeping level, for example, switching off computers overnight and at weekends, results in energy and cost savings of 70 per cent to 80 per cent. Equally, switching off monitor when at lunch, or during periods of absence, can halve the energy consumption….]


A simple calculation shows that an enterprise with 40.000 PCs could easily save more than one Million USD per year by just better managing the power of its PCs.


Real Life Example

This example shows a company with 500 PCs. 250 were managed with Auto Shutdown Manager, the other 250 PCs were not. This is an analysis of a 12 months period.

Many PCs were left on after business hours and at weekends as indicated by the blue chart. Auto Shutdown Manager reduced this by 47% as shown by the green chart.

In numbers:
For the 250 managed PCs, the company reduced the power costs from 27,830 Euros to 14,656 Euros.
This means a saving of approx. 30,000€ or $40.000 USD for all 500 PCs per annum without changing the hardware or user behavior. Measured on the average Return On Sales of 3% this saving equals a revenue of $1,330,000 USD.

Furthermore, many IT tasks became easier with build-in features such as auto save of open documents before shutdown, remote shutdown, remote wakeup, enterprise wide WoL Scheduler and a central power management for all PCs. Another key aspect is the improved security level while all unused PCs are shut down now automatically.
