Service · Building envelope
Building envelope & insulation — passive performance, structurally addressed.
Optimise the passive performance of buildings through coherent envelope, insulation and airtightness strategies — anchored in the broader energy trajectory.
The challenge
Envelope works often deliver less than promised.
Insulation, airtightness and façade interventions are frequently scoped on isolated thermal calculations, without articulation to ventilation, HVAC, regulation and long-term operations. The delivered performance rarely matches the design assumption.
- 01Thermal calculations disconnected from real ventilation and HVAC operation.
- 02Envelope works planned without coordination with regulatory obligations.
- 03Insufficient attention to thermal bridges, airtightness and durability.
- 04No structured post-works verification of performance.
How we support
Envelope, framed inside a building strategy.
We treat the envelope as one component of the building's energy system — designed and delivered in coherence with HVAC, ventilation, regulation and operations.
Strategic framing
Position envelope works inside the broader energy and asset strategy.
Coordinated design
Articulate envelope with ventilation, HVAC and regulatory constraints.
Delivery oversight
Secure airtightness, thermal bridges and quality on site.
Performance verification
Structure post-works verification and integration into operational steering.
Scope of intervention
Envelope & insulation capabilities.
Insulation strategies
External and internal insulation strategies adapted to the asset's typology.
Façade & roof works
Structuring of façade and roof renovation programmes.
Airtightness & thermal bridges
Design and verification of airtightness and thermal bridge treatment.
Openings & glazing
Optimisation of glazing, openings and solar protection strategies.
Regulatory alignment
Articulation with tertiary decree, regulation thermique and certification frameworks.
Post-works verification
Definition of verification protocols and integration into monitoring.
Methodology
Envelope work, applied through our six-phase framework.
Every envelope engagement follows the same six-phase sequence — from passive performance assessment through to long-term verification.
Assessment
Diagnostic of envelope performance, ventilation logic and constraints.
Strategy
Definition of envelope strategy aligned with the asset trajectory.
Planning
Sequencing of studies, procurement and works phasing.
Execution
Coordination of works, with discipline on airtightness and bridges.
Monitoring
Verification of as-built performance and integration into steering.
06 · Continuous improvement
Feedback loops into the broader asset and portfolio strategy.
