RE2020 Compliance

France RE2020 ADEME Environment Construction HVAC LCA Compliance

Overview

Draft the environmental performance summary for new buildings under France’s RE2020. Covers IC construction and IC énergie (kgCO₂/m²), LCA narrative with bio-sourced materials, threshold validation, and ADEME/ministerial alignment. France; construction and HVAC. Includes carbon_threshold_validator to check that kgCO₂/m² values in the summary stay within RE2020 2025-step limits (2025–2027).

Example conversation

You: We need the environmental performance summary for a new collective housing project in France. Include the LCA narrative and make sure we’re within RE2020.
Agent: I’ll draft the summary using the RE2020 skill: context (logement collectif), performance énergétique, then impact carbone with explicit IC construction and IC énergie in kgCO₂/m², and confort d’été. I’ll structure the LCA narrative around bio-sourced and low-carbon choices. Once the draft is ready, I’ll run carbon_threshold_validator with building_category logement_collectif to confirm we’re within the 2025-step limits (IC construction ≤ 650, IC énergie 260–320).
You: Our IC construction came out at 620 and IC énergie at 285 — can you run the validator on the summary file?
Agent: (Runs carbon_threshold_validator on the file.) Both values are within RE2020 2025-step limits for logement collectif. The report lists the extracted figures and confirms compliance.

Excerpt of a performance summary (impact carbone)

The agent drafts the carbon section with explicit figures so the validator can check them. Example:

## Impact carbone (RE2020)

- **IC construction** : 620 kgCO₂/m² (seuil RE2020 step 2025 : 650 kgCO₂/m² pour logement collectif).
- **IC énergie** : 285 kgCO₂/m² (plage cible 260–320 kgCO₂/m²).
- Stratégie : matériaux biosourcés et bas carbone ; chauffage collectif.

carbon_threshold_validator reads these values and confirms they are within the 2025-step limits for the chosen building category.

Extension tool

carbon_threshold_validator — Run on the environmental performance summary or LCA document after drafting or revising. It:

Check	Requirement
IC construction	Value(s) in the document must be ≤ 530 kgCO₂/m² (maison individuelle) or ≤ 650 kgCO₂/m² (logement collectif) for the 2025 step.
IC énergie	Value(s) must lie in 160–200 kgCO₂/m² (maison individuelle) or 260–320 kgCO₂/m² (logement collectif).
Building category	Pass `building_category` (`maison_individuelle` or `logement_collectif`) so the tool applies the correct thresholds; if omitted, both sets of limits are considered.

The tool extracts numbers associated with “IC construction” and “IC énergie” (and common kgCO₂/m² phrasing), then reports which lines comply or exceed the limits. Use it before finalising the summary for submission.

Getting Started

Add your source materials (building programme, LCA data, energy assumptions) to the project workspace, then activate the RE2020 Compliance skill. The agent will structure the performance summary, align the LCA narrative with RE2020 indicators, and run carbon_threshold_validator to confirm thresholds before you submit.
