From construction to refurbishment, including global performance contracts, Spie batignolles supports the transformation of buildings to meet the challenges of sustainability. This pitch will highlight the solutions implemented to design sustainable buildings, combining user comfort, energy performance, and the use of renewable materials.
District heating networks powered by renewable and recovered energy are among the most powerful tools for rapidly decarbonizing the building sector. Nordic models have demonstrated this for several decades: when well-planned, supported, and connected on a large scale, these networks enable a massive shift away from fossil fuels.
In France, the potential remains considerable but is still underutilized. The Multi-Year Energy Plan (PPE3) sets an ambitious goal: to triple the number of district heating networks. This requires a genuine shift in scale: accelerating projects, securing business models, mobilizing local governments, connecting more multi-unit housing, and making better use of local resources.
This roundtable will compare European experiences with French realities to identify persistent barriers to deployment: financing, public acceptance, regional engineering, building connections, availability of renewable heat, and local governance. Above all, it will examine the conditions needed to make district heating networks a central tool for the widespread decarbonization of housing.
How can the threefold increase announced by the PPE3 be transformed into a truly operational pathway? What role should local governments play in local energy planning?

Fulfilling new functions is the challenge facing roofs today in the face of climate, energy and regulatory challenges. In a context marked by a regulatory framework increasingly favourable to the combined development of green roofing and photovoltaics, Jean Damian, Director of Soprasolar, will present Soprasolar Nature, SOPREMA's new bio-solar solution. This innovative approach combines solar energy generation, green roofing and water management on a single roof. A genuinely virtuous system, bio-solar creates a synergy where each element benefits the other: vegetation improves the performance of photovoltaic panels while the panels promote the development of biodiversity. A practical solution for designing higher-performing, more energy-efficient buildings.
