# /epd-parser

Extract structured environmental impact data from EPD PDFs

[Install ↓](#install) [View on GitHub →](https://github.com/AlpacaLabsLLC/skills-for-architects/tree/main/skills/epd-parser) [New to skills? →](/articles/claude-code-cheat-sheet) [All skills →](/skills)

[Specifications](/skills?tag=specifications) [Analysis](/skills?tag=analysis)

## What it does

Type `/as:epd-parser` with one or more EPD PDF files. The skill extracts text via PyMuPDF, parses impact indicator tables, and structures the data into a 42-column schema covering product identity, EPD metadata, environmental impacts across life cycle stages, resource use, and LEED eligibility.

Handles EN 15804+A1 and +A2 formats, multi-product EPDs, non-English documents, and varying table layouts across program operators (UL, NSF, Environdec, IBU, ASTM).

## Install

**Claude Desktop:**

1.  Open **Customize** → **Browse plugins**
2.  Click **+** → **Add marketplace from GitHub**
3.  Enter `AlpacaLabsLLC/skills-for-architects`
4.  Install **Architecture Studio**

**Claude Code (terminal):**

```
claude plugin marketplace add AlpacaLabsLLC/skills-for-architects
claude plugin install as@skills-for-architects
```

Or symlink just this skill:

```
git clone https://github.com/AlpacaLabsLLC/skills-for-architects.git
ln -s $(pwd)/skills-for-architects/skills/epd-parser ~/.claude/skills/epd-parser
```

## Usage

```
/as:epd-parser ~/Downloads/EPD11075.pdf
```

A folder of EPDs:

```
/as:epd-parser ~/Documents/project-epds/
```

## What it extracts

-   **Product identity** — manufacturer, product name, declared unit, CSI division
-   **EPD metadata** — registration number, program operator, PCR, standard version, validity dates, system boundary
-   **Impact indicators** — GWP-total, GWP-fossil, GWP-biogenic (A1-A3), plus A4-A5, B1-B7, C1-C4, D when available
-   **Additional impacts** — ODP, AP, EP, POCP
-   **Resource use** — renewable/non-renewable primary energy, fresh water, recycled content, waste
-   **LEED eligibility** — flags product-specific vs. industry-average, third-party verification status

## Pairs with

-   [`/as:epd-compare`](/skills/epd-compare) — compare parsed EPDs side-by-side
-   [`/as:epd-research`](/skills/epd-research) — find more EPDs for the same product category
-   [`/as:epd-to-spec`](/skills/epd-to-spec) — turn parsed GWP values into specification thresholds
