Energy efficiency: Digitalisation

Moderising energy efficiency through digitalisation.

Quarterly webinar series: Our first webinar featured guest speaker David Nemtzow from the US Department of Energy Building Technologies Office presenting on the Grid-interactive Efficient Buildings Program. 350 people from 80 countries participated. Subsequent webinars will feature other initiatives and case studies from around the world. 

Workshops: We will organise two workshops during 2019, the first in Paris on 27 March featuring discussions on policy approaches to enabling private sector engagement and innovation, as well as examining how governments can use digitalisation to improve the effectiveness of their own programmes. The second workshop will take place in September 2019 and feature illustrative case studies of best practice globally.

Digitalisation within the energy sector presents a significant opportunity to transform end-use and systems efficiency. The IEA is tracking emerging trends in using digital technology to enable greater energy efficiency gains within specific sectors and across multiple end-uses, as well as within the wider energy system context.


Based on our conversations with government officials, representatives from industry, and other energy efficiency stakeholders, there is a need for greater clarity on how digitalisation is enabling greater energy efficiency, as well as how policymaking itself is being transformed through the use of digital tools and techniques.

The workshop will explore:

- How have policies been designed to exploit the impacts of digitalisation on energy efficiency in three areas, how have these policies enabled private sector innovation, and how can this be improved?

- Active energy management systems (e.g., mandatory requirements for building automation)

- Data-driven consumer engagement platforms (e.g., smart meter data sharing platforms)

- Performance-based revenue models (e.g., public-sector procurement and contracting models

- How have governments leveraged new digital tools to better manage and monitor specific programmes (e.g., digitised tracking and surveillance, geo-targeting, M&V)?


Outcomes from this workshop will be integrated in the IEA’s new online digitalisation resource library, publically accessible via our global exchange for energy efficiency, and launched ahead of our 4th Annual Global Conference on Energy Efficiency in Dublin on 24 June. The online resource will feature a collection of case studies from across the globe, results from deeper research and analysis on select topics, and policy recommendations. IEA analysis on the expected impacts from digital technologies on energy efficiency will also feature significantly in this year’s market report, Energy Efficiency 2019.

Paris, France: 31 January 2019

Time: 4 PM - 5 PM CET

Our first webinar in the IEA’s cross-agency initiative – Modernising Energy Efficiency through Digitalisation – included Brian Motherway, Head of the IEA’s Energy Efficiency Division, who launched our new initiative and introduces our first guest speaker, David Nemtzow, Director of the U.S. Department of Energy’s Building Technologies Office, who presented on the Grid-interactive Efficient Buildings Program. We are grateful that David was able to help kick-off this webinar series, as his team has been doing great work demonstrating the value energy efficient buildings can play in delivering significant, cost-effective grid resources.

This first event was a huge success, drawing nearly 400 participants from 61 countries representing government, research organisations, private industry and large energy users. The Q&A was very lively, with more than 40 questions – most of which we couldn’t get to, so stay tuned for a summary of the questions so that we might continue the discussion.

In the meantime, the copies of the presentations and the webinar are available online.

Some background on the U.S. Department of Energy (DOE) Building Technologies Office & Grid-Interactive Efficient Buildings Program

Changes in technology, consumer choice, and grid modernization allow for a future in which buildings play an even greater role in supporting a modern electric grid. Efficient and flexible building loads provide options to increase electricity system reliability and energy affordability, while also supporting a portfolio of generation options in grid modernization. To date savings resulting from flexible building loads have been primarily achieved through traditional energy efficiency and demand management programs. However, advanced controls, sensors and data analytics developed over the last decade provide new ways to optimize building energy savings and energy use, by autonomously managing a variety of distributed energy resources (DER) including on-site solar panels, energy storage, electric vehicles, and various demand-side assets, while maintaining and even improving comfort to occupants, and contributing to a reliable, affordable grid.

The U.S. Department of Energy (DOE) Building Technologies Office (BTO) is 1 of 9 technology offices within DOE's Office of Energy Efficiency and Renewable Energy (EERE). BTO leads a network of national laboratory, university, small business, and industry partners to develop innovative, cost-effective energy saving solutions for U.S. buildings. BTO focuses on accelerating the pace of innovation in technologies for both existing buildings and new construction. Its vision is to advance a strong and prosperous country in which all homes and buildings operate at peak energy performance, are affordable, and provide optimal health conditions and comfort. BTO's mission is to develop, demonstrate, and accelerate the adoption of technologies, techniques, tools, and services that are affordable, as well as to enable high-performing, energy-efficient residential and commercial buildings in both the new and existing buildings markets.

Speaker biography

David Nemtzow, Director of the BTO within the U.S. DOE’s Office of EERE, brings more than three decades of experience in energy, including in industry, government, utility, non-profit associations, and consulting in the U.S. and abroad. David is responsible for leading this $225 million per year office that helps develop innovative, cost-effective energy efficiency R&D and other solutions for U.S. building technologies, equipment, systems and whole buildings. Previously, he was Director-General (CEO) of the Department of Energy, Utilities, and Sustainability for New South Wales, where he played a central role in the State’s electricity, greenhouse, energy, and water strategies and policies. He also served as President of the Alliance to Save Energy, a prominent Washington, D.C.-based association of industry, government, utility, consumer and environmental executives that promotes investment in energy efficiency. David earned a master’s degree from Harvard University in public policy and a bachelor’s from Brown University in environmental policy.
