Networked devices and networking equipment, as integrated systems, have the potential to contribute significant net energy savings. While it costs energy to maintain network connection and enable system-wide solutions, energy savings gained from holistic system design can outweigh gains from individual device-specific improvements.
On June 26th, 2014, the US Environmental Protection Agency (EPA), in conjunction with the Information Technology Industry Council (ITI), held a joint workshop to explore roles for the ENERGY STAR program and others in promoting energy savings using such system effects, pathways to defining and measuring systems/intelligent efficiency, and opportunities for leadership and education.
Our goals for the workshop included:
- Deepening our collective systems perspective (as opposed to device only perspective);
- Deepening our understanding of the language and landscape of metrics for measuring system efficiency;
- Identifying areas of shared interest in educating a wide range of users; and
- Identifying specific next steps to continue this work, to include the development of educational materials and the potential for pilot projects.
Results and Next Steps
EPA and ITI summarized the results of the workshop as follows,
- Progress on definitions for intelligent systems efficiency.
- Agreement to develop both value proposition for and models for implementing systems efficiency.
- Interest in developing case studies for use with facility operators and policy makers; also a potential data source for metrics work.
- Interest in determining ways to verify savings claims from IT efficiency providers (akin to the ENERGY STAR Power Management Campaign).
- Interest in engaging measurement and verification (M&V) experts from utilities to make it more likely that incentives can be offered.
- Metrics require much more discussion (interest in testing some smaller systems and using the learnings to inform metric development).
As regards to next steps, we are pursuing a continuing dialogue, and we are moving forward as follows,
- This website will continue to be updated.
- A list serve has been created. If you would like to be removed, or if anyone would like to be added, contact either Chris Hankin email@example.com or Erica Logan firstname.lastname@example.org.
- We will schedule a series of quarterly conference calls to further the outcomes of the workshop by: organizing project leads and volunteers; developing methods for vetting and sharing our work; and monitoring progress.
- Our first call was held on Tuesday, September 30th, 2014 (192KB). Review the summarized results (383KB) of the first call.

This Workshop built on previous conversations between the EPA, ITI members, and other key stakeholders on the potential savings from, and technical requirements for, system energy efficiency. This topic was part of the road-mapping workshop and exercise begun in 2012; view the Track 2 Informing Document (186KB) and other materials from that effort.
