SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Identify and quantify environmental impact differences across 2+ products by validating comparability and producing a structured report.

Core Features & Use Cases

  • Side-by-side comparison of environmental impact data (GWP, PCR alignment, system boundaries) across 2+ products.
  • Generates markdown reports with comparison tables, percentage deltas, LEED v4.1 MRc2 eligibility notes, and data quality flags.
  • Use cases include validating data from Google Sheets, inline data, or CSV/Markdown files, and evaluating EPDs from multiple manufacturers.

Quick Start

Provide EPD data sources (sheet rows, pasted values, or a file) and run the /epd-compare command to generate a report.

Frequently Asked Questions about epd-compare

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I compare environmental impact data from two different EPDs?▼

To compare environmental impact data from two EPDs, the Skill validates product comparability, normalizes units, and generates a structured markdown report with side-by-side tables, GWP deltas, and LEED v4.1 MRc2 readiness flags.

What is the best way to check if products meet LEED MRc2 requirements using EPD data?▼

Checking LEED MRc2 requirements involves validating PCR alignment and system boundaries across products. The Skill generates a LEED assessment by flagging LEED v4.1 MRc2 eligibility directly within the comparison report.

Can I use EPD data from a Google Sheet to generate a side-by-side environmental impact comparison?▼

Yes, you can use EPD data sourced from Google Sheet rows, inline pasted values, or CSV and Markdown files. The Skill reads this data without writing back to the source to produce the comparison document.

How does EPD comparison handle mismatched units and PCR boundaries?▼

When comparing EPDs with mismatched units, the Skill normalizes the values when possible. It also flags PCR boundaries to ensure the environmental impact comparability across the selected products is valid.

What are the limitations of comparing EPDs from different manufacturers?▼

A key limitation is data comparability; if PCR boundaries do not align or units cannot be normalized, the comparison may be invalid. The Skill flags these data quality issues and LEED readiness but does not write corrections to the source.
