Policy Brief – Upstream Consequences from Connected Devices
Connecting devices to the internet has profound implications for energy use, in three areas: Digitalisation, Wasted Energy and Upstream Consequences. This policy brief covers the third topic – Upstream Consequences. This policy brief is based on two EDNA reports: Total Energy Model for Connected Devices and Intelligent Efficiency for Data Centres & Wide Area Networks
Policy Brief – The Role of Connected Devices in the Digitalisation of the Energy System
Connecting devices to the internet has profound implications for energy use, in three areas: Digitalisation, Wasted Energy and
Policy Brief – Wireless Charging Energy Use
This briefing summarises the key findings of the EDNA report Global Forecast of Energy Use for Wireless Charging, which estimates the additional global energy that would be consumed if wireless charging is adopted for a wide range of small consumer devices
Policy Brief – Energy Harvesting Technologies for IoT
This briefing summarises the key findings of the EDNA report Energy Harvesting Technologies for IoT Edge Devices, which explores the potential to deploy Energy Harvesting Technologies (EHTs) to convert energy from the surroundings into electricity, in order to power small internet of things (IoT) devices
Test Procedures for Measuring Network Standby Power
This paper examines elements of existing test procedures that address network standby in some way. This includes horizontal test procedures that cover standby and network standby for a wide range of products, as well as product-specific procedures where network functionality is a common or essential feature of the product
Global Forecast of Energy Use for Wireless Charging
In this report, we have built on the modeling methodology published in a recent white paper by Natural Resources Defense Council (NRDC) and Suzanne Foster Porter of Kannah Consulting
Bridging the Network Standby Gap between Mobile and Mains-Powered Products
An integrated, energy-optimal design approach, in which disparate engineering teams collaborate iteratively toward energy optimization goals (including low network standby energy use), is currently the
Getting to Zero: An Evaluation of Zero Network Standby Power
This report examines the feasibility and economics of achieving network zero in three different products: mini-split HVAC systems, smart speakers, and connected light bulbs. We investigate the range of network standby
Total Energy Model for Connected Devices
The objective of this study is to develop a quantitative model of the “total energy use” of connected devices, globally. This report (and model) aims to quantify the total additional energy that results from devices becoming connected to a communications network
Intelligent Efficiency for Data Centres and Wide Area Networks
This report discusses the energy consumption of data centres (DC) and the wide area network (WAN) which connects computers and other devices together on the internet. These are complex
Policy Brief – Intelligent Efficiency: Smart Homes
This briefing summarises the key findings of the EDNA report Intelligent Efficiency – A Case Study of Barriers and Solutions – Smart Homes. Energy efficiency policy makers need to better understand
Policy Brief – Networked Audio Products
This briefing summarises the key findings of the EDNA report Network Connected Audio Products – Measurements and Analysis of Network Standby Consumption, which focuses on larger audio products that use WiFi to communicate. The report uses
Energy Harvesting Technologies for IoT Edge Devices
This report discusses the elements of an energy harvesting system, and the possible energy sources and quantities of energy which can be harvested from light, thermal energy, radio frequency
Network Standby Power Basics (revised April 2018)
This report incorporates and organizes our collective understanding of the network standby function, identifies the primary factors that influence its power draw, develops a framework for understanding these factors, and estimates power ranges associated with different network standby function implementations.
Intelligent Efficiency – A Case Study of Barriers and Solutions – Smart Homes
This report highlights the role of energy efficiency policy makers in improving the value proposition for smart homes for energy management, by supporting the development of methodologies and studies quantifying benefits, and the provision of accessible information to consumers via labels or other mechanisms
EVSE Scoping Study for 4E
The delegates from EDNA member countries decided to conduct a Scoping study, to investigate the energy performance of Electric Vehicle Supply Equipment (EVSE), looking also at the existing policy approaches for this emerging product group. This Scoping study
Policy Brief – Energy Aware Devices
This briefing summarises the key findings of the report Energy Aware Devices – Study of Policy Opportunities, which outlines why and how network-connected devices can be cost-effectively harnessed to report their own, individual energy consumption
Standby Consumption Measurements
This document summarises the standby and networked standby measurements of the following products and concludes the compliance with ecodesign requirements: Standby consumption of 31 TVs, 14 audio equipment, 5 printers, 9 complex set top boxes
Encouraging Intelligent Efficiency – Study of Policy Opportunities
This research project investigated the policy and program opportunities for governments to encourage greater investments in network connected devices and their application in reducing
Energy Aware Devices – Study of Policy Opportunities
This report addresses a technical concept, “energy aware” devices, that enables energy use data of individual devices in buildings to be made available by the devices themselves. Energy aware devices
