LCBI awards its first low-carbon labels in Germany and Belgium to The Stack in Munich and Luxia in Brussels

5 sep. 2025

Two European real estate developments, both developed by AXA IM Alts, effectively open new countries for the Low Carbon Building Initiative. The Stack and Luxia have been awarded the LCBI label, underlining their ambitious low-carbon performance. The whole process has been validated by a reliable third party, Bureau Veritas. The Low Carbon Building Initiative (LCBI), launched in 2022, has created the first European label that measures a building's carbon footprint over its whole life cycle, enabling actors to limit it.

Paris, 4th September 2025.  LCBI (the Low Carbon Building Initiative), launched in 2022 by European real estate major players and BBCA (the Association for the Development of Low Carbon Buildings), awarded two new international labels in Brussels and in Munich, on the occasion of the SIBCA (the low-carbon real estate trade fair), taking place from 3rd to 5th September in Paris.

The Stack, timber offices in Munich

AXA IM Alts has launched the construction of ‘The Stack,’ a c. 17,100 sqm timber hybrid office asset in the centre of Munich. The scheme, designed by Wilmotte & Associés Architectes and implemented by RKW Architektur +, aims to achieve market-leading environmental credentials, combining a sustainably sourced timber hybrid construction method with green energy technology  and biophilic design features. Overall, the strategy has allowed to drastically reduce the project’s carbon footprint compared to a typical new-build development, reaching the XXX LCBI level at design-stage.

Low-carbon and health-friendly construction materials have been used with approx. 1,800 cubic meters of spruce wood from Austria, with an amount of 325.5 kg CO2e/m² embodied carbon (30% less than DGNB-certified solid construction). 
Regarding energy, The Stack is supplied with district cooling and district heating by Munich's municipal utilities and uses 100% green electricity, allowing to reach Operational 8.27 kg CO2e/m² in Operational Carbon, i.e. 40% less compared to the DGNB benchmark.

Smart tech has been used every time it was fit, with for instance CO₂ sensors and variable ventilation systems dynamically adjusting the air quality to the occupancy of the room.

Luxia, low carbon offices connected to Brussels city center

Luxia is a a high-end and low-carbon office building developed by AXA IM Alts.  Designed by the Brussels architects firm DDS+, the recently delivered state-of-the-art building 13.000 sqm GFA is conceived as a circular building. Indeed, Luxia is built on preserved foundations and re-uses many materials and the concrete of the demolished building, allowing to drastically reduce the carbon footprint of its construction phase.

Conceived as a pioneering low-carbon project, Luxia is the first project receiving the LCBI Certificate in Belgium, reaching the LCBI Performance level at delivery stage. Achieving the highest score on all ESG-performances, it is recognized as one of the most sustainable buildings of Brussels, going from Breeam Outstanding, Well Gold, PEB A to Airscore A, Wiredscore Gold, and the labels Fossil-Free and Biodivercity.

With the ambition to minimize the overall carbon footprint of the project, Luxia has managed to reduce Co2 emissions on all phases of the buildings’ life cycle. Indeed, the carbon footprint of the construction phase, measured on full scope, is limited to 931 kgCO2e/m² (50yr) and the annual operational carbon to a very low 11,2 kgCO2e/m². The energy consumption is drastically lowered to 48 kWh/m²/year, by using heat pumps, solar energy and a comprehensive smart building approach.

AXA IM Alts

Luxia project benefits from a strong location and is positioned as a high-quality product on the Brussels market. Luxia increases the stock of Green Assets for our client, and will, as a future proof building, fully contribute to our ambitious ESG-strategy. The LCBI-certification process enabled us to keep a 360° view as from the design phase. Also, it allowed us to maintain a coherent grasp of the interests of our client, the end-user and for the future of the asset.

AXA IM Alts

The Stack presents an opportunity to fulfil the demand in premium, ESG-oriented, well connected office space in Munich’s city center, only 2min away from the central station. With completion set for the beginning of 2026, the pre-letting quote of ca. 60% reflects the appeal of our flexible and collaborative office concept, attracting forward-thinking users. As the first LCBI-certified office building in Germany, this development affirms its commitment to sustainability and was designed to meet the evolving needs of sophisticated tenants and align with our global investment principles.

LCBI Director

We are delighted to award two new certifications in Brussels and in Munich, extending the LCBI footprint already settled in Milan, Paris and Belval (Luxemburg). We are showing that the progress of real estate decarbonization in Europe relies on the implication of local stakeholders, at each step of a building project. We are proud that our technical expertise is sufficiently well-recognized in Europe to attract the interest of major players in the real estate sector such as Axa IM Alts. It is a matter of considerable pride for us to see that these companies have embedded the issue of decarbonization by showing their confidence in our technology.

... Some figures from BBCA, the association behind the LCBI initiative, revealed at SIBCA on the same day in France:

  • In 2025, 2.25 million m² were committed to or certified by BBCA (compared to 1.55 million in 2024 and 1.48 million in 2023). New builds account for 43% of production.
  • In just one year, BBCA has certified nearly 700,000 m², an increase of nearly 100% compared to 2024.
  • Since 2016, BBCA applications in progress or certifications have exceeded 5.7 million m² (compared to 4.55 million in 2024), corresponding to 760 projects in 2025 (compared to 630 in 2024).

About LCBI 

The Low Carbon Building Initiative was launched in 2022 by major players in the real estate sector (Generali Real Estate, Covivio, BPI Real Estate, BNP Paribas Real Estate, Bouygues Immobilier, WO2, Icamap, NSI, Ivanhoé Cambridge and AXA IM Alts) and BBCA (the Association for the Development of Low-Carbon Buildings). Its aim is to develop the low-carbon certification of real estate projects in Europe in order to hasten the decarbonisation of the sector. Based on key European standards and benchmarks, the LCBI methodology serves to standardise the practice of life-cycle analysis (ACV) throughout Europe. The LCBI label, audited by Bureau Veritas and CERTIVEA, takes account of the complete life cycle of buildings, and measures the carbon footprint as well as the comprehensiveness of the ACV on three levels: grey carbon (emissions associated with construction) measured in kgCO2e/sq.m over 50 ans, carbon from use (linked to consumption and energy sources) measured in kgCO2e/sq.m./year, and the measurement of biogenic carbon storage contained in the building measured in kgCO2e/sq.m. The label has three performance levels: Standard, Performance and Excellence.
