  Thai-LCA  v1.0.0
  Early-Stage Embodied Carbon for the Thai AEC Market
  TGO May 2026 Emission Factors · GRESB-Aligned · Food4Rhino
===============================================================

REQUIREMENTS
------------
  Rhino 8 SR7+ or Rhino 9
  Grasshopper (built-in with Rhino 8+)
  CPython 3.9+ — enabled in Rhino 8 Script Editor by default
  No third-party Python packages required


INSTALLATION  (2 steps)
-----------------------

Step 1 — Install the engine (once per machine)
  Copy Scripts\lca_engine.py to your Rhino scripts folder:

    %APPDATA%\McNeel\Rhinoceros\8.0\scripts\

  This file contains all 39 TGO 2026 emission factors.
  Restart Rhino after copying.

Step 2 — Install the components
  Copy all .ghuser files from the UserObjects\ folder into:

    %APPDATA%\Grasshopper\UserObjects\

  Restart Grasshopper (or right-click the toolbar and Refresh).
  A "Thai-LCA" tab will appear with all 8 components.


COMPONENTS
----------
  01 | Inputs
    TH-Map        Material Mapper     — Geometry/layer -> volume + MatID
    TH-Assembly   Layer Assembly      — Multi-layer wall/slab carbon builder
    TH-Rebar      Rebar Estimator     — Concrete volume -> rebar mass

  02 | Analysis
    TH-Carbon     Carbon Estimator    — Volume + MatID -> kgCO2e (A1-A3+A4)
    TH-B6         Operational Energy  — kWh/yr -> B6 lifetime carbon
    TH-Compare    Material Comparison — Side-by-side A vs B delta

  03 | Reporting
    TH-ESG        ESG Report          — GRESB intensity + Bangkok REIT band
    TH-Export     CSV Export          — Full carbon schedule to file


TYPICAL WORKFLOW
----------------
  TH-Map -> TH-Rebar -> TH-Carbon (x zones) + TH-B6 -> TH-ESG -> TH-Export
