The §5.8 Table-14 added-insulation R-value adjustment was gated to
WALL_SOLID_BRICK, so a stone (granite/sandstone) wall lodging
wall_insulation_type 1/3 ("External"/"Internal") + a thickness fell
through the §5.6 thin-wall branch and was billed at its UNINSULATED U
(e.g. sandstone 520 mm + 100 mm internal: 1.64 instead of 0.30 → ~5×
the wall heat loss). Mirror the brick insulation branch into the stone
block, feeding the RAW §5.6 U₀ into the §5.8 chain per the same rule the
brick branch and the dry-lined granite pin 000565 already follow (the
Table-6 footnote (a) 1.7 cap does not apply on the insulated path).
Corpus cert 100052159386 (sandstone 520 mm + 100 mm internal): -26.20 ->
-4.08 SAP, walls 300 -> 55 W/K. RdSAP-21.0.1 corpus within-0.5 68.6% ->
68.8% (SAP MAE 0.942 -> 0.888; PE MAE 14.3 -> 13.9; CO2 0.27 -> 0.26);
floors/ceilings ratcheted. Unit-pinned in test_rdsap_uvalues.

Model Repository
This repository contains the code pertaining to the development of the data science and machine learning products being utilised by Hestia.
The different folders in this repository relate to services that can be used independently, or can be imported and used as part of a larger application
Getting Started
Prerequisites
Dev Container Setup
This repo uses a Docker Compose-based dev container. The model-backend service joins a shared-dev Docker network so it can communicate with other local services (e.g. a frontend container) running on your machine.
VS Code users: The initializeCommand in devcontainer.json creates the shared-dev network automatically before the container starts. No manual step required — just open the repo and select Reopen in Container.
Non-VS Code / CI workflows: Run the following once before starting the container:
make dev-setup
This is idempotent and safe to re-run if the network already exists.
Folders
backend/
This folder contains the code for the fastapi backend service, which provides an interface to much of the functionality in this repository, for the frontend
model_data/
This folder contains related to the reading and preparation of assessment model data, including pulling out epc attributes
Testing
All tests can be run, against the configuration in pytest.ini running
pytest
This will run the complete panel of tests and report on coverage in the locations specified by the pytest.ini file.
To run tests in a specific service, e.g. inside of model_data, simply run
pytest --cov-config=model_data/.coveragerc --cov=model_data
This will produce the test results and coverage reports
