SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires openpyxl, and includes scripts (resource) components.

What problem does it solve?

Manually calculating embodied carbon from BIM quantity takeoffs is time-consuming and error-prone, creating bottlenecks for sustainable design and carbon reporting in AEC projects.

Core Features & Use Cases

  • Material-to-Coefficient Mapping: Automatically matches BIM material names to built-in generic carbon coefficients for A1-A3 life-cycle stages.
  • Aggregated Carbon Summaries: Generates totals by material, category, life-cycle stage, and building level, plus per-square-meter metrics when gross floor area is provided.
  • Flexible Input/Output: Accepts CSV, JSON, or Excel input files, and exports results to structured JSON or multi-sheet Excel workbooks for sustainability dashboards.
  • Use Case: For a design team comparing concrete vs. timber structural options, this skill quickly generates comparable embodied carbon totals to inform low-carbon material selection.

Quick Start

Use the co2-carbon-footprint skill to calculate the total embodied carbon in kg CO2e from your BIM quantity takeoff file and specified project gross floor area.

FAQPage Schema
How do I calculate embodied carbon from BIM quantity takeoff data?

To calculate embodied carbon from BIM quantity takeoff data, you can use a skill that matches material names to carbon coefficients for A1-A3 life-cycle stages and outputs structured carbon summaries. It accepts CSV, JSON, or Excel files containing element material and quantity fields.

What is the best way to compare embodied carbon between concrete and timber structural options?

The best way to compare embodied carbon between concrete and timber options is to process BIM quantity takeoffs through a carbon calculation tool. This generates comparable totals by material and category, enabling design teams to quickly inform low-carbon material selection.

Can I use Excel files with material and quantity fields to generate a sustainability dashboard report?

Yes, you can use Excel files with material and quantity fields to generate a sustainability dashboard report. The tool processes the input and exports results to structured JSON or multi-sheet Excel workbooks containing aggregated carbon summaries.

How do carbon coefficients map to generic BIM materials for AEC design-stage analysis?

Carbon coefficients map to generic BIM materials through an automated matching process that assigns built-in coefficients for A1-A3 life-cycle stages. This supports AEC design-stage analysis by translating standard material names into measurable kg CO2e values.

Does this carbon footprint calculation support per-square-meter metrics when gross floor area is provided?

Yes, this carbon footprint calculation supports per-square-meter metrics when gross floor area is provided. It generates these metrics alongside aggregated totals by material, category, life-cycle stage, and building level for comprehensive project analysis.
