Power Factor Basics
OK. I’ve heard a lot about this power factor stuff. What exactly is it? We hope to give you an easy explanation of what power factor is, and to answer the following most asked questions. Question 1: What is Power Factor
Evaluation of policies to reduce Standby Power and Development of Standard Methodology
The objective of this study is to provide a uniform international methodology to evaluate the impact of SPIs in countries having
Provision of a horizontal policy approach to standby power
This report presents a framework for analysing policies at an international level that aim to address standby power in electrical end-use equipment.
What has the Standby Annex Achieved 2009-2011?
Summary of Major Achievements of the Standby Annex 2009-2011. Alignment of data collection methodology provides policy makers with baseline information and a tool which can assist in the design, monitoring and evaluation of different policy approaches
Cutting Edge Technology Feasibility Study
The focus of this research was to investigate the feasibility of power saving cutting edge technologies for set-top boxes, game consoles and IP phones. These three products were chosen, as the majority of products in these categories consume as much power while in idle
Low Energy Product Design Series – AC-DC PowerSupplies: Building a Better Brick
This report on ac-dc conversion is one of two in this series that cover efficient technologies used in designing power supplies
Low Energy Product Design Series – Standby Power: The Phantom in the Machine
Standby power, also called “vampire power” or “phantom power”, refers to the small amount of electricity consumed by many appliances when they are switched off or are not being used for their primary function.
Estimate of the Energy Wasted by Network Connected Equipment
The objective of this study is to estimate the energy wasted by network-connected equipment due to excess connectivity and that could be saved through better power management policies.
List of Technical Standards for Equipment Connected to Energy-Using Networks
This report is a non-exhaustive review of technical standards from 2010 relevant for network connected equipment. It reviews the standards perceived by the authors as the most relevant that could potentially form the basis of a consistent international standard
Testing Products with Network Connectivity
This report documents many existing requirements relevant to testing products with networks and sets out key issues to be considered. The main specifications in existence are in the Energy Star program and in the European Codes of Conduct
Power Scaling in Proportion to Data Processing
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
Energy Reporting on Networks
The widespread lack of knowledge of how much energy is used by particular devices or end uses in buildings is a well-known barrier to identifying savings opportunities from equipment that is inherently inefficient, performing anomalously, or being operated
Overview of Estimate of the Energy Wasted by Network Connected Equipment
The objective of this study is to estimate the energy wasted by network-connected equipment due to excess connectivity on a global and regional level. The report looks at the amount
Investigation and exploration of network power consumption in Set op Boxes, VOIP Telephones and Games Consoles.
The report investigates the power scaling and control opportunities and the potential for power consumption savings and
Standby Power and Low Energy Networks – issues and directions
This study examines the issue of networked products and identifies key areas where energy saving strategies can be implemented. A critical component is power management across all modes – shutting down unnecessary capacity or functions when they are not required while meeting all relevant user needs.
