Lorillard Bâtiment joins the Rénov'Acteurs 2026 tour

A national tour focused on localized energy renovation

The Rénov'acteurs 2026 tour is part of a strategy of territorial deployment of energy renovationThe event is based on a structuring principle: there is no single solution applicable to the entire French building stock.

This initiative mobilizes several institutional and technical actors, including local energy and climate agencies (ALEC), ADILs, and ARECs. The objective is to promote a contextualized reading of renovation projects, by integrating the economic, climatic and heritage constraints specific to each territory.

"There is no single renovation model, but rather a plurality of solutions adapted to different areas."

This approach aligns with the guidelines of the RE2020 environmental regulations, which requires a comprehensive consideration of the energy performance and carbon impact of the works, while allowing room for adaptation according to local contexts.

An operational presence through professional exchanges

In this context, Lorillard Bâtiment will operate through regional "business corners". These spaces for exchange aim to create a direct dialogue between field teams and project owners.

The relevant stakeholders include:

• public and private project owners
• Architects
• thermal engineering firms
• project management assistants (AMO)

These meetings help to identify concrete problems, such as:

• renovation of the building envelope while the site is occupied
• the improvement of summer comfort in existing buildings
• the compatibility between energy performance and heritage constraints

"These exchange sessions allow us to identify the specific problems of each territory and to provide concrete solutions."

A common example concerns the renovation of facades in dense urban environments, where architectural constraints require tailor-made solutions, such as the integration of high thermal performance joinery without visible modification of the exterior appearance.

A structured territorial network and an integrated design office

Lorillard Bâtiment's participation is based on a network of regional agencies Developed over more than ten years, this network allows for intervention as close as possible to operations, with better responsiveness on construction sites.

Each agency has:

• of integrated design officeresponsible for diagnostics and technical solutions
• of a capacity for managing works, including site monitoring and coordination of trades

This organization promotes a comprehensive approach, from initial thermal analysis to implementation.

In practice, engineering firms use dynamic thermal simulation tools to assess energy savings and anticipate summer overheating. These analyses influence technical choices, particularly regarding windows and doors or shading systems.

Expertise focused on the building envelope

Lorillard Bâtiment, a specialist in building envelope renovation, focuses on several technical levers:

• improvement of the thermal performance of windows and doors
• managing solar energy input to limit overheating
• durability of materials over time
• adaptation to existing structural constraints

The building envelope is a key element in the overall performance of a structure. It directly impacts heat loss and occupant comfort.

However, an operational limitation remains: improving the building envelope alone is insufficient to meet energy targets if it is not combined with a renovation of the systems (heating, ventilation). This comprehensive approach is, moreover, recommended by standards such as the BBC renovation label.

Stages in several major cities

The Rénov'acteurs 2026 tour includes several stops across the country:

• Rennes – April 9, 2026
• Lyon – April 23, 2026
• Nantes – April 29, 2026
• Bordeaux – May 21, 2026
• Paris – June 10, 2026
• Lille – October 8, 2026

These steps cover real estate markets with varied characteristicsranging from urban collective housing to tertiary or heritage buildings.

Each territory constitutes a specific case study. For example, the renovation issues in Lille differ significantly from those encountered in Bordeaux, particularly due to climatic conditions and construction typologies.

A case-by-case approach to renovation

Lorillard Bâtiment's participation in this tour illustrates a fundamental trend in the sector: the need for a custom renovationtailored to each project.

This logic is based on a combination of factors:

• technical constraints of the existing building
• energy objectives of the project owner
• Cadre réglementaire
• economic conditions of the project

It involves close coordination between the various stakeholders on the construction site, from the design office to the project manager, in order to ensure the consistency of the solutions implemented.

In a context of mass energy renovation, this individualized approach remains a major challenge to guarantee the real performance of the works, beyond the theoretical objectives.
