Building for the Climate | Succeeding in the Environmental Transition

Building for the Climate | Decarbonising Without Sacrificing Profitability

What if building for the climate also meant remaining profitable ? This is the message shared by the speakers at the event of the same name organised by Le Moniteur. Far from guilt-driven narratives, architects, manufacturers and financiers outlined a pragmatic roadmap.

Concrete is being decarbonised through innovation. Biomimetic architecture is proving its economic viability, with an additional cost of only 5 to 10%. Financing mechanisms are multiplying. For architectural practices, this transition represents both an organisational and technical challenge. OOTI provides the keys to anticipate, manage and successfully deliver environmental transformation.

Office Building Decarbonisation | Why Your Data Is Your Greatest Asset

The tertiary real estate sector is at a decisive turning point. Between rising vacancy rates and increasing environmental requirements, it must anticipate the transformation of its building stock.

The key ? A deep understanding of your buildings. The importance of data in the built environment has never been greater. Dang Tran, CEO of La Poste Immo, highlighted that his group spent more than 10 years building a comprehensive database of its property portfolio. In 2016, due to the lack of suitable tools on the market, La Poste Immo even created its own subsidiary, Sobre Energie, dedicated to energy management.

Technical solutions already exist. Improving the building envelope can reduce energy consumption by up to 30%. Installing a heat pump can cut carbon emissions by up to 90%. The challenge lies in finding the right balance for each individual building.

To support industry players, ADEME has launched the DETER scheme, a call for projects targeting property owners with multiple buildings, within a global portfolio strategy.

Concrete on Trial | A Verdict That Changes the Game

During the event, concrete was symbolically put on trial. Prosecutor, defence lawyer, jury — all the elements of a real courtroom drama were in place.

The question posed to the audience: should this material be condemned for its carbon legacy, or given a chance to reinvent itself?

The cement industry has not remained idle. Stéphane Herbin, Director of Cimbéton at France Ciment, recalled that reducing volumes is a key part of the sector’s decarbonisation roadmap. Two French projects have been selected by the European Union for low-carbon transformation: Airvault GOCO2 (Heidelberg Materials) and Vaia (Vicat).

The future also lies in material hybridisation. Integrating bio-based materials reduces the carbon footprint while maintaining essential requirements: structural stability, fire safety and acoustic comfort.

The verdict ? Acquittal. The audience expressed confidence in the sector’s innovation efforts — some even shouted “long live concrete!” from the crowd.

Biomimetic Architecture | When Ecology Becomes Profitable

Long perceived as utopian, the projects of Vincent Callebaut are now proving their viability. Invited on the “Building for the Climate” podcast, the Belgian architect advocates a pragmatic approach.

His method ? Biomimicry — a comprehensive strategy that integrates vegetation, water and energy from the very first stages of design.

His Paris Smart City 2050 study, conducted with Setec Bâtiment, helped shape reflections around Paris’s bioclimatic urban plan (PLU). In Taipei, the Tao Zhu Yin Yuan Tower embodies this vision with its double-helix, plant-covered structure.

From a budget perspective, the architect acknowledges an initial cost increase of 5 to 10%. This gap is quickly offset by reduced operating costs, on-site energy production and increased asset value, a key profitability lever for architectural practices. In France, his projects in Montpellier and Aix-les-Bains focus on rebuilding the city within itself to limit urban sprawl.

Financing the Transition | Which Levers to Activate?

The ecological transition of the building sector requires massive investment. The Pisani-Ferry report estimates funding needs at €66 billion per year by 2030.

Several mechanisms can support this effort : eco-conditional loans, ADEME grants through the DETER scheme, and green bonds. Data sharing between property owners and tenants is also a crucial driver for collective action on decarbonisation.

Building for the climate is no longer a utopia. Innovation, data and investment are making the transition achievable. To manage these complex projects, architectural practices need the right tools. Solutions like OOTI guide you through this transformation. Contact us for a demo.
