LCA threshold

Unblock an exceeded LCA threshold (collective housing)

ARKEMEP optimises the life cycle assessment before filing to bring the carbon indicator back below the RE2020 threshold. This is a design engineering assignment.

Getting back below the carbon threshold before filing

When the Ic_construction indicator of a collective-housing project exceeds the RE2020 threshold, the permit filing is at risk. The lever is upstream: material and construction-method choices, per-package LCA calculation, design trade-offs. ARKEMEP conducts this optimisation as an engineering firm, before the file is blocked.

It is a design engineering assignment, not coupled to any certification. The earlier it starts in the programme, the more room there is to bring the indicator below the threshold without inflating the operation.

FAQ

Frequently asked questions

The optimisation focuses on material choices, per-package LCA calculation and design trade-offs, upstream of the filing. ARKEMEP conducts this engineering; no certification is coupled to it.

Thresholds tighten through successive regulatory steps (2025, 2028, 2031). ARKEMEP calibrates the design LCA below the applicable threshold to absorb construction-phase variation.
