The Environmental Protection Agency (EPA) will introduce new ENERGY
STAR 4.0 requirements on July 20th, 2007. What's going to change?
What do you have to do to get compliant? Relax, it's easier than you
think - HP can give you a head start. Even if you're a small
business not concerned about compliance, you can still save money on
power and cooling by implementing ENERGY STAR 4.0 compliant desktops
from HP.
|
| Simply to drive innovation in improving energy
efficiency. The EPA has shifted their strategy for this
generation of the ENERGY STAR program. ENERGY STAR 3.0 used an
inclusive approach with a philosophy that the more systems
that are compliant, the greater the total aggregate power
savings. ENERGY STAR 4.0 uses an exclusive approach where top
tier systems will really push the envelope of power
efficiency. |
|
ENERGY STAR 4.0 in a nutshell |
|
|
| There are two fundamental changes from the
current ENERGY STAR 3.0 program to the ENERGY STAR 4.0 that
will have a decided impact on your organization should you
choose to implement the new standards: |
|
|
1. |
Idle power under the operating system will now
be measured and used as a metric to earn the ENERGY STAR 4.0
rating as opposed to Standby power. |
|
|
2. |
An 80% efficient power supply is a
requirement. |
|
The difference between ENERGY STAR 3.0 and
4.0 |
|
|
| ENERGY STAR 3.0 was concerned with Standby
power. By 2005, all HP systems could meet the requirements.
Since the customer adoption of Standby-state was slower than
the EPA expected, the EPA had to focus attention to the
growing number of computers that sat idle rather than
transitioning into Standby. |
|
| In Standby, the number of storage devices,
processor cores, graphics power, memory etc. makes very little
difference to the power used. These devices are either turned
off or are in a very low power state. However, in idle, all
these devices are drawing power. The amount of memory or the
number of hard drives has a big impact on power used. This is
why the ENERGY STAR 3.0 configuration you're buying today
might not be a configuration that will meet ENERGY STAR 4.0 in
the future. If you need (or simply want) to consider
compliance, you have to look at the idle wattage, not just
Standby. |
|
| The 80% efficient power supply is a principal
requirement of Energy Star 4.0 and a major new
innovation. |
|
| What is an 80% efficient power supply? When a
power supply converts AC power from the wall to the various DC
voltages that the computer needs, there is always a loss of
power. The power loss varies with how busy the computer is. An
80% efficient power supply is guaranteed to lose less than 20%
of the AC power at 20%, 50% and 100% loads. Currently, power
supplies for desktop computers range from approximately 65% to
75% efficiency. |
|
| The lower idle specification plus the 80%
efficient power supply together provide big benefits to your
business beyond simple compliance: |
|
|
• |
Increased power supply reliability due to
greater efficiency |
|
|
• |
Decreased system maintenance due to increased
reliability |
|
|
• |
Lower TCO due to reduced maintenance and longer
equipment life |
|
|
• |
Improved worker environment with less noise
from the PC |
|
|
• |
Potential reduction in cooling bill due to less
heat being generated by PCs |
