 Beyond Network Standby: A policy framework and action plan for low energy networks  - Energy Efficient Strategies  (60 pages)

 

This report examines digital networks and the associated energy use, propsing a pathway and action plan to reduce consumption.  Readers are provided with an understanding of how networks operate and how products that are connected to a network can minimise the network energy overhead.  The IEA guiding principles are explained in terms of real world applications.  The report also contains recommendations on definitions and how to apply these to energy policy.  The report concludes by providing a path forward for efficiency policy in the area of networks. The report is a companion piece for the soon to be released IEA/4E Network Standby publication.

 Power Requirements for Functions  - Xergy Consulting (52 pages)

 This report builds on the previous work (ECOVA's Mapping Secondary

Product Functions report) examining in greater detail several high-priority

secondary functions to further quantify their power requirements and

provide the technical background that might be required to advance

horizontal policy action associated with these functions. 

 

 

   

 

 

   

 

 Mapping Secondary Product Functions to Products and 

Operational Modes - ECOVA (51 pages)

This project comprehensively examined secondary functions for the

first time by identifying, defining, and classifying the relevant functions

across three broad categories of consumer products: major appliances,

home entertainment, and office products. the project conducted market

research to identify the prevalence of each secondary function across

products and to determine how frequently those functions are used in

various modes of device operation. Tables or “maps” were generated of 

each function to identify clusters of functions with the greatest horizontal

applicability across different products and modes of operation.

 

 

   

   

Guiding Principles for Energy Efficiency in Networked

Consumer Electronics
In 2013 key Consumer Electronics Industry Associations from around the

world published  11 Guinding princples for energy efficency in Networked

Consumer Electronics.  These principles draw on those developed previously

by the IEA and 4E.

Staying Connected:

Unravelling energy waste issues in network standby

 Maia Consulting  (34 pages)

This report presents policy makers with an overview of the fast

moving developments in network standby and provides a window

into what policy options might be available to reduce network
standby energy waste.

Estimate of the Energy Wasted by Network Connected Equipment

BIO Intelligence Service  

(30 Pages).  This report for the first time identifies the scale of the network

standby issue and demonstrates that with the implementation of effective

energy efficiency and power management policy substantial energy wastage

could be prevented.

 Overview of Estimate of the Energy Wasted by Network Connected Equipment


    

 

List of Technical Standards for Equipment Connected to

Energy-Using Networks - BIO Intelligence Service

(73 pages).  This report provides a non-exhaustive review of technical

standards relevant for network connected equipment from 2010.  It

reviews the standards perceived as the most relevant that could form the

basis of a consistent international standard, covering: pure technical

standards, power measurement specificationsor test methods, and

mandatory or voluntary environmental performance standards.

 Energy Reporting on Networks - Nordman 

(13 pages) This document discusses the concept of energy reporting on

networks where devices report information on their status, power levels and

energy consumption that could be used for power management purposes.  A

standard method for Internet Protocol-connected devices to provide this

information is seen as an essential element to achieve the maximum benefit

for managing energy use and efficiency in the coming decades.  This report

documents progress by the Internet Engineering Task Force to establish such

a protocol.


    

Testing Products with Network Connectivity - Nordman 

(20 Pages).  This report acknowledges that with many new developments

in hardware and software associated with networks, energy testing procedures

need to be updated and some new approaches required.  A global

harmonisation of test procedures and specifications around network

connectivity is proposed and suggestions made as to where further work is

required to develop these.

 


 

    

 Cutting Edge Technology Feasibility Study - ecos 

(35 pages). This report investigates the power scaling and control

opportunities and the potential for power consumption savings and benchmarking

for three product groups: Complex set Top Boxes, Voice over Internet Protocol

phones and game consoles.  It concludes that opportunities exist for reduction

in energy consumption in the three product groups through design focussing on

energy consumption and performance such as power scaling and multi- voltage

switching power supplies. 


 Overview of Cutting Edge Technology Feasibility Study


    

 Power Scaling in Proportion to Data Processing - ecos

 (30 pages). This report examines the power scaling abilities for a variety

of electronic products, both network equipment (modems, routers and switches)

and “edge devices” with multimedia and audio-visual capabilities e.g. game

consoles, DVD Players.  The opportunities for reducing energy consumption

with power scaling for many of the products tested are evident.

 Investigation and Exploration of Network Power Consumption

in Set Top Boxes, VOIP Telephones and Games Consoles - ADT

(35 pages). This report investigates the power scaling and control

opportunities and the potential for power consumption savings and

benchmarking for three product groups: Complex set Top Boxes, Voice

over Internet Protocol phones and game consoles.  It concludes that

opportunities exist for reduction in energy consumption in the three

product groups through design focussing on energy consumption and

performance such as power scaling and multi- voltage switching

power supplies.

 Examples of Low Energy Product Designs - ecos

Ecos produced six brochures outlining examples of low energy product

design for electrical appliance components that provide global energy

saving opportunities.  The brochures provide a brief discussion on the

relevance of each area to standby power consumption and present

cutting edge low power product designs for components of electrical

appliances that are either currently available or under development. 

Combined these could have significant impacts in reducing standby

energy consumption.  The individual reports can be accessed below.

Guiding Principles for Energy Efficiency in Networked Products
In 2007 IEA Digital Networks Workshop developed some “guiding principles” that both could underpin both the network design and policy objectives future network designs. These principles can be used to evaluate existing and proposed network technologies and designs. At the 4E-APP technical expert network standby workshop in Paris April 2010, these principles were updated with some minor revisions. Since then the APP Standby Project, the 4E Standby Annex and the APEC standby Power Conference all accepted these principles as the basis for future work in this field.

 

    

 

Standby Power and Low Energy Networks : Issues and Directions

Energy Efficient Strategies 
(150 pages). This report plays a crucial role in identifying the issues

surrounding network standby and why existing methods for dealing with

standby power and low power mode are not directly transferrable to the

problem.  The report identifies a number of areas where the existing

knowledge is insufficient and proposes new research be undertaken to fill

the gaps.
