The EPC renders a recent-band as-built wall as "<material>, as built, insulated (assumed)". The API mapper populates epc.walls with that string, and heat_transmission's wall_ins_present gate keyed off the "insulated" substring → routed the wall to the RdSAP 50 mm "insulation of unknown thickness" bucket (e.g. sandstone band J U=0.25) instead of the as-built age-band row (U=0.35). Per RdSAP 10 Table 8/9 footnote the 50 mm row applies ONLY when insulation is "known to have been increased subsequently (otherwise 'as built' applies)". An "as built ... (assumed)" description is the EPC's age-band assumption — it only renders on RECENT bands (an old band renders "no insulation (assumed)"), so the as-built row applies. Genuine retrofit is signalled by wall_insulation_type (External/Internal/Filled), which the gate still checks independently. Worksheet-validated by two new Elmhurst worksheets, both As Built band J: - simulated case 9: sandstone → (29a) U 0.35 - simulated case 10: solid brick → (29a) U 0.35 both the as-built row, NOT 50 mm (0.25). Fix: restrict the description-based gate to genuine retrofit via the new local `_described_as_retrofit_insulated` (excludes "as built"/"(assumed)"). The cavity filled-row routing inside `u_wall` (which uses `_described_as_insulated` directly) is untouched — the 3 cavity API certs (0390/0535/7536) are unaffected. test_heat_transmission: the old `..._uses_50mm_row` test asserted 50 mm via an IMPOSSIBLE band-B + "insulated (assumed)" combination; corrected to a valid recent-band (J) scenario asserting the as-built row (35 W/K). Golden 0240: walls 24.45 → 34.23 W/K (U 0.25 → 0.35). SAP integer 72 unchanged; PE residual re-pinned +1.8687 → +5.5044, CO2 +0.0907 → +0.2757. This spec-correct fix REMOVED the wall under-count that was masking the Ext1 vaulted-roof over-count (cascade U 0.68 via the same "insulated (assumed)" description vs case-9 sloping-ceiling 0.25) — that roof over-count is the next slice; fixing both lands SAP cont ≈ 72.31 (= Elmhurst case 9).

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
