Energy performances in European Real Estate. Deepki, the most trusted sustainability solution for real estate, published its annual Deepki Index – the only publicly available European benchmark of the real estate industry’s environmental performance, using real consumption data.
Now in its fourth year, the Index enables real estate players to track the evolution of the European building stock’s energy consumption across six major markets in near-real time, based on a sample of over 400,000 assets.
Since it was first published in late 2022, the Index has been well received by a market lacking a common framework to address increasingly stringent regulations. It has quickly become a vital reference point for asset managers, investors, and regulators seeking to align global business strategies with regulatory initiatives such as the EU Taxonomy. In 2025, Deepki goes further still, publishing its first results for the U.S. building stock, measuring the performance of two typologies across six regions.
Key findings from the 2025 European Deepki Index
Europe’s building stock continues to show a year-on-year reduction in terms of final energy intensity. The analysis reveals that most typologies studied have reduced their energy consumption since 2022 – logistics (20%), offices (16%), health (13%) and housing (12%). This reduction can be attributed in part to recent energy efficiency regulations, which have prompted retrofitting investment and changing patterns of building use. However, variations across countries and asset types shows that energy performance remains closely linked to regional and sectorial performance and progress remains fragile.
The hotel sector across Europe continues to see a year-on-year increase in final energy consumption, with an 18% increase since 2022 as the industry sees occupancy return to pre-pandemic levels.
The European retail sector has traditionally been more volatile, with energy use fluctuating in line with regional inflationary pressures, consumer sentiment and political uncertainty. After a 14% spike between 2023 and 2024, the mean energy consumption has dropped this year by 9% and consumption is now closer to 2022 levels.
Country-specific trends in energy consumption
United Kingdom
The UK data indicates there has been a general decline in average energy consumption across all typologies since 2022’s Index – with the logistics and health sectors seeing a 24% and 22% decrease in consumption over three years. The only exception is the hotels sector, whose consumption levels have plateaued, at just 1% higher than 2022 levels. However, despite some improvement, the UK’s real estate sector remains one of the largest CO2 emitters, underlining the need for continued investment in energy efficiency.
France
France continues to post some of the strongest efficiency gains across all real estate typologies, driven by the binding requirements of the Tertiary Decree. Final energy consumption by France’s logistics sector has fallen by 20% compared with 2022, as they see e-commerce levels return to normal after a post-pandemic boom. However, French hotels continue to see a rise (10% increase) in average final energy use in 2024 compared with 2022, which could be linked to a surge in demand when the country hosted the Olympic and Paralympic Games.
Germany
Germany’s real estate sector continues to observe decreases in final energy intensity, with offices down 7% year-on-year and its logistics sector’s energy usage decreasing by 11% in a weaker macroeconomic environment. This trend is even more pronounced when comparing to 2022 levels, with consumption across the office and logistics sector decreasing by 26% and 21% respectively.
Sandrine Fauconnet, Senior Associate, ESG & Sustainability at Stoneweg, comments: “The Deepki Index is much more than just a tool: it is the benchmark that the market needs to transform its ambitions into concrete actions.”
Flora Adamian, Senior Analyst, Sustainability at Bellwether, comments: “Clear, data-driven benchmarks are important for advancing sustainability in real estate. Tools like the Deepki Index can help bring greater transparency and alignment across the industry.”
Vincent Bryant, CEO and co-founder of Deepki comments: “The Deepki Index reveals that while European real estate has made energy improvements in recent years, progress remains fragile and uneven, often driven by macroeconomic factors and weather, rather than structural change. These factors represent an opportunity for real estate players to align sustainability with financial performance, by leveraging sustainability to reduce vacancy. That being said, the sector remains far from meeting the targets of the Paris Agreement, which will require continued commitment and decisive action.”
About the Deepki Index
First published for regulatory purposes, the Deepki Index has since evolved into a vital tool that helps decision-makers combat climate change by benchmarking their assets against the environmental performance of their peers, according to asset type and location. The Index gives values for the average, top performing 30% and top performing 15% in terms of final energy, primary energy and CO2eq emissions for different typologies across the real estate sector in the UK, France, Germany, Benelux, Italy and Spain, equipping companies to align with regulations such as the European Taxonomy.
The publication of Deepki’s latest Index findings marks three years since its launch as the first publicly available European benchmark measuring real estate’s environmental performance using real data. Following its initial publication, it was positively received by the market, which was lacking a common framework in order to tackle the challenges brought about by tightening regulations, such as the SFDR.
To redirect investment flows in line with the 2050 net zero target, the European Commission has detailed performance criteria in the EU Taxonomy. According to these criteria, buildings in the top 15% of the national or regional building stock in terms of primary energy intensity are considered sustainable investments and serve as a benchmark for the entire sector, while buildings in the top 30% are deemed to do “no significant harm”.
In 2025, Deepki extended its Index to cover 2 typologies across 6 regions of the United States.
