With over 2,000 attendees in 2025, the Sustainable Building Congress has consolidated itself as the must-visit forum for knowledge, debate and reflection for the entire construction ecosystem. Every year, it brings together architects, engineers, builders, property developers, manufacturers…
For the 2027 programme, we are focusing on the six themes that are setting the agenda within the industry. Discover them below.

THEMES
The sector’s key challenges at the heart of the debate. Find out more!
Housing, the City and Regeneration
Housing is today one of the main social, economic, and territorial challenges of our cities. The need to expand affordable housing coexists with the transformation and renovation of an existing building stock that must adapt to new environmental, social, and demographic demands.
Regeneration means acting on buildings, neighbourhoods, and public spaces while preserving their identity and improving urban quality. Collaboration between the administration, private sector, and professionals is key to accelerating this transformation. Architecture, housing and city are thus considered as parts of the same challenge: to build more liveable, accessible, resilient and inclusive environments.
Habiltability, Health and Comfort
The quality of a building depends not only on its efficiency or technical performance but also on how it contributes to the well-being of the people who live in it. Air quality, thermal and acoustic comfort, light, accessibility, and materials have a direct impact on health and the daily experience of spaces.
Biohabitability and healthy design incorporate these factors from the very conception of buildings. Efficient building envelopes, healthy materials and interior design solutions make it possible to combine comfort, wellbeing and reduced resource consumption. Building better also means building with people in mind.
Industrialisation and Construction Systems
Industrialisation involves an evolution of the traditional construction model towards more planned, standardised, and integrated processes. Prefabrication, modularity, offsite construction, DfMA, and hybrid systems allow part of the production of the work to be transferred to more controlled industrial environments.
The objective is to increase productivity, reduce deadlines and incidents, and improve quality and safety. This transformation also changes the relationship between architects, engineers, manufacturers, builders, and developers. Construction thus approaches an industrial logic based on designing, manufacturing, transporting, and assembling with greater precision and efficiency.
Materials, Circularity and Decarbonisation
The reduction of the environmental impact of construction necessarily involves rethinking the materials we build with and their life cycle. Low-carbon, bio-based, recycled or reused materials offer new alternatives to conventional systems.
Circularity introduces a perspective that goes beyond the finished building and considers the origin of the resources, their durability, maintenance, dismantling, and possible reuse. Tools such as life cycle assessment and material passports make it possible to better measure and manage this impact. Decarbonising ultimately involves transforming both the products and the way of designing, building, and recovering resources.
AI, Data and Productivity
Digitalisation is turning information and data into a new infrastructure for the construction process. BIM, artificial intelligence, digital twins, automation and robotics enable better connection between the design, production, construction and subsequent operation of buildings. Technology makes it easier to anticipate problems, coordinate teams, automate tasks and make better-informed decisions.
At the same time, it drives new Construction Tech companies and business models that challenge traditionally highly fragmented processes. The challenge is not just to incorporate more technology, but to use it to genuinely increase productivity, quality, and the competitive capacity of the sector.
Innovation and the Future: Products, Architecture, Talent and Impact
Innovating in construction means turning new ideas into products, systems, projects and ways of working that can generate a real impact. New materials, industrialised solutions, applied sustainability, and quality architecture coexist with another major future challenge: having the necessary people to make this transformation possible.
The lack of skilled labour, generational turnover, and the need for new technical profiles force a rethink of trades, training, and the professional appeal of the sector. Digitalisation and industrialisation are also changing the skills required on construction sites and within companies. The future of construction will depend as much on its ability to innovate as on its ability to attract, train and retain talent.
