## Example Prompts

- Draft the environmental performance summary for a new collective housing project in France
- Check that IC construction and IC énergie in the summary are within RE2020 2025 limits
- Structure the LCA narrative for a single-family house with bio-sourced materials and validate carbon thresholds

## 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:

```markdown
## 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.
