Action on energy efficiency requires both technological and social change

Although sometimes overlooked in the race to devise innovative solutions to the climate crisis, energy efficiency remains crucially important. Energy efficiency has contributed to greater savings in primary energy and faster reductions in emissions compared to the transition to renewable energy resources. While the growth in global energy consumption dropped by 2.1% during the pandemic year of 2022, the growth rate remains higher than the average rate measured from 2010 to 2019. What can we do to slow this rate of growth, or even reverse it?

One of the best ways to take immediate and effective action is to transition from conventional lighting to energy-efficient LED lighting. LED light sources consume less than half the energy consumed by incandescent and fluorescent light sources, and up to 80% less energy when managed in a connected system. An individual light bulb or luminaire consumes a small amount of energy, but since lighting is everywhere that people are, the global lighting footprint is significant.

This means that transitioning to energy-efficient lighting solutions can have a significant effect. Since economic growth results in global increases in the use of artificial lighting, inaction will result in a significant increase in global energy consumption for lighting by 2030. While the global transition to energy-efficient LED lighting is moving very quickly—approximately 85% of lighting sales at Signify are LED today, for example—there are still significant benefits that can be gained by accelerating the depletion of the installed base of conventional lighting, which still accounts for almost 50% of all light points in the EU and the US. In fact, the worldwide switch to LED and connected LED could decrease global energy demand for electricity by 30%, while at the same time reducing carbon emissions by 1.4 billion metric tons a year. The switch is easy and relatively inexpensive to make, in both residential and commercial built environments.

It is important to keep in mind that making the transition to energy-efficient lighting involves not just technological change but also social change. People should be willing to make the switch. Individuals have to understand the positive effects of well-managed LED lighting on comfort and well-being. Businesses and cities have to understand its advantages not only in terms of energy and emissions reductions but also in terms of improvements to operations and quality of life.

A sense of urgency is appropriate. But fearmongering and finger-pointing will not bring about the necessary social change. Instead, the emphasis has to be on taking effective energy-efficiency action and improving the quality of life, work, and the economy. With the right approach, we can have our cake and eat it too.

Enhancing EU security & resilience via energy efficiency: 2023 in review

The EU-ASE 2023 Activity Report delves into the advocacy and outreach efforts of the European Alliance to Save Energy, aimed at enhancing energy efficiency in the EU’s energy policies and integrating the water-energy nexus into mainstream considerations.

2023 can be viewed as a continuation of the previous one, marked by escalating geopolitical issues and an energy crisis. Throughout the year, EU-ASE actively implemented its workplan by significantly contributing to energy efficiency debates and participating in ongoing negotiations on legislative dossiers.

We also organized the second edition of the European Energy Efficiency Day, bringing together high-profile speakers who contributed to discussions on energy efficiency in buildings, industrial ecosystems, and the electricity market. The event also delved into the skills agenda within the sector.

We continued our work on the implementation of a work programme which was structured around the main objectives of:

  • Boosting energy efficiency through EU policy and regulatory framework
  • Unleashing the energy savings potential of water efficiency in EU legislation
  • Smart, digital, and effective communication to achieve advocacy objectives

System efficiency in 2024: Three priorities for the next EU Commission

System efficiency is a key metric to evaluate how far the European Green Deal has taken us in the energy transition.  

Why system efficiency and what is it?  System efficiency is the measure of how well a system utilizes resources to achieve its desired output with minimal waste. In this context, it refers to the systematic application of the Energy Efficiency First (EE1) principle. This means that examining system efficiency provides a way to assess the broad socio-economic advantages linked to measures improving energy efficiency. 

To maximize efficiency, we need to accelerate the decarbonisation of buildings, ensure that future energy networks are designed to electrify most of the economy, while strategically focusing on using hydrogen in hard-to-electrify applications as gas networks are decommissioned due to declining fossil gas demand. 

The recent agreement on the Energy Performance of Buildings Directive (EPBD) only requires minimal obligations for Member States, leaves flexibility for fossil fuel technologies, and avoids banning certain heating technologies in buildings. 

Despite positive steps such as establishing the European Network of Network Operators of Hydrogen (ENNOH) to counter fossil gas industry influence, challenges remain in the gas package directive, which applies hydrogen unbundling rules only to Transmission System Operators (TSOs), leaving Distribution System Operators (DSOs) exempt and potentially leading to costly hydrogen investments at the local level. 

Considering the above, the next EU Commission can improve overall energy system efficiency by following three priorities: 

  1. Making energy efficiency an energy security priority through a new task force that focuses on leveraging energy efficiency progress and demand flexibility as an active lever towards European energy security. 
  2. Making local delivery institutions fit for delivering energy efficiency, providing increased support for municipalities and regional governments and setting targets for system transformation. 
  3. Enhancing system efficiency in gas networks by establishing a framework for decommissioning obsolete fossil infrastructure and strategically designing hydrogen networks for areas where no other decarbonisation option exists.

Repetition Is Key: The Latin Maxim “Repetita Iuvant” Holds True.

Since the European Commission unveiled the Clean Energy for All Europeans package on 30 November 2016, including the Energy Performance of Buildings Directive (EPBD) revision, the alliance has consistently played a central role in shaping its contents. Through collective efforts we have actively contributed position papers, organized events, and proposed amendments — all available on our website.

Why do we need an ambitious final revision of the EPBD? Below are my three compelling reasons:

Energy and Emissions Impact: Buildings account for approximately 40% of energy consumption and 36% of CO2 emissions in the EU. They stand as the largest energy consumers in Europe. To maintain our competitive edge while the clean energy transition reshapes global energy markets, we must act on buildings.

Greenhouse Gas Reduction: The EPBD represents the primary EU policy avenue for tackling both operational and embedded greenhouse gas emissions in the building sector. This approach will effectively decarbonize the EU building stock, boost the EU building sector’s competitiveness, create new employment opportunities, and support the research, development, and innovation of relevant technologies.

Sustainability Strategies: The final EPBD revision should incorporate sustainable strategies such as circularity, sufficiency, and the utilization of low-carbon and natural-based materials. These strategies are essential for reducing Whole Life Carbon emissions and ensuring the decarbonization of buildings. Phasing out fossil fuels from new heating and cooling systems across the EU must happen by 2030.

Stay tuned and join us to making a significant impact by reaching a deal on the Directive by the end of 2023.

Digital Twin of buildings: a way to enhance energy efficiency and net zero commitments

Buildings in the EU are responsible for 40% of energy consumption and 36% of greenhouse gas emissions that includes construction, usage, renovation and demolition phases (1). Legislation such as the European Energy Performance of Buildings Directive (EPBD) is progressively addressing these challenges by establishing concepts of zero emission and nearly zero emission buildings. The EU Energy Efficiency Directive (EED) established the “how” by universal deployment of smart meters and high-efficiency drives. The EU Renewable Energy Directive (RED) paved the way for renewables and waste heat recovery in the urban environment. Digitalization brings it all together.

Digital Twins are a representation of real-world physical assets that serves for simulation, integration, testing, monitoring, and maintenance purposes.

In the context of buildings, Digital Twins bring numerous benefits. First, it connects the smart building to the smart city so that a building is no longer managed as an isolated entity but as an active cell in a larger organism with which it interacts at many levels: people, goods, utilities and data.

Second, it leverages AI to build complex models, forecast, reduce risk and send early warnings on any areas of interest: from building occupancy and comfort temperature to biological risks and cyber attacks.

Third, it makes sustainability and carbon footprint visible real-time and therefore actionable. It also reinforces District Heating and Cooling’s advantages for heat delivery, sustainability and affordability.

Last but not least, it is easy to implement without disrupting current building infrastructure, ideal for building renovations as well it is technology agnostic, it leverages all utilities and sensors already installed (telecoms, water, power, surveillance, HVAC).

In conclusion, digital twins of buildings are a good way forward to drive an ambitious energy efficiency and net zero agenda in the future that should be considered by policy-makers, local authorities and stakeholders.
