The type of machine and its peripherals (notebook vs. desktop, LCD vs. CRT, etc.), the type of PC usage (on the internet vs. off-line, heavy use - all drives spinning, processor-intensive tasks vs. light use – email, word processing, etc.), as well as the use of Time-Out Settings (ready for use vs. sleep/hibernation mode, screen saver vs. monitor off, etc.) are all factors that affect energy use. It is with this understanding that the SyAM Power Management time-out and scheduler capabilities allow for the reduction in power consumption throughout the workday (via the effective management of Timeout Settings) when the systems are inactive, and more importantly the ability to gracefully power off non-critical systems when not required, both at the end of each workday and on weekends. It should also be pointed out that, although not controlled by the SyAM Power Management tool, other ancillary savings related to reduced cooling costs can also be recognized as a result of reduced heat generated by the PC’s during off hours when these systems are not in use and shut down.

In order to accomplish this feat, Power Management can be configured individually for each Desktop, Notebook or Server utilizing SyAM’s s Central Management interface. It should also be noted that SyAM Software will soon be supporting Group Action and Power Policies that will enable clients to group and categorize systems by location, function, etc. which will further simplify the Time-Out and Shutdown settings. Once configured, the Power Management agent will store all settings and will perform the power functions with no user or administrator intervention required. When calculating the amount of electricity a Personal Computer will consume, IFS utilizes the following formula: (Wattage x Hours Used Per Day) / 1000 = Daily Kilowatt-hour (kWh) consumption and Daily Kilowatt-hour (kWh) consumption x Cost per Kilowatt-hour = Total Cost Therefore; Watts x Hours Used X Cost per Kilowatt-hour X Number_of_PC_Units = TOTAL COST 1000Published US Department of Energy information: Computers:

For illustration purposes, let’s perform a conservative estimate of the savings that a business with 300 PC Workstations that are eligible for power management scheduling can recognize. We will use Dell Dimension XPS 600’s which have a specification of 142 to 200 Watts, hence a 171 Watts average usage, and each PC has an efficient LCD Monitors that uses 75 Watts each. We will assume that the PC’s will only be turned off for only 10 hours (overnight) each weekday and 48 hours each weekend. We will not take into consideration any additional savings by using Timeout Settings during the workday, nor will be estimate any additional savings that could be gained thru reduced air conditioner use. Finally, let us assume that on average this company is paying $0.14 per kWh. Using the calculation that was previously identified, and incorporating the use of SyAM’s Power Management to shut the PC’s off for just 10 hours each weekday and 48 hours on weekends, the following savings can be recognized:
The savings are like an annuity as they are certain to occur each year thereafter, as long as active power management through SyAM remains a part of your overall IT infrastructure. * All potential energy cost savings shown are estimated. Your actual savings may vary. IFS, inc. makes no guarantee of actual cost savings. |
