Closes the Ext1 vaulted-roof over-count that S0380.209 exposed on golden
cert 0240-0200-5706. BP2 lodges roof_construction=5 (vaulted ceiling),
roof_insulation_thickness="NI" (parsed to 0), description "Pitched,
insulated (assumed)", band J. The cascade returned U=0.68 — the RdSAP 10
§5.11.4 (p.44) retrofit-50 mm "insulation at joists" row. A vaulted /
sloping ceiling has no ceiling-joist void, so that row does not apply; per
RdSAP 10 §5.11 Table 18 (p.45) it takes the column (1) age-band default
(band J = 0.16).
The arbiter is the cohort, not the spec text alone: 33 cohort-2 certs
lodge "ND" (thickness None) vaulted roofs (roof_construction=5, band D)
that already pin to their dr87 worksheets at U=0.40 = Table 18 col (1) by
falling through the age-band default. 0240's only difference is the "NI"
sentinel (insulation present, unknown thickness) which uniquely hit the
0.68 override. (The S0380.209 note's predicted "cont ≈ 72.31" assumed a
col-3 0.25 value; the cohort's ND vaulted roofs disprove that — they use
col (1), so 0240 lands at cont 72.4617.)
Implementation: new `u_roof(is_sloping_ceiling=...)` flag, threaded from
heat_transmission for roof_construction_type containing "sloping ceiling"
(code 8) or "vaulted" (code 5). It fires only for the NI case
(thickness 0 + "insulated (assumed)"), routing to the col (1) age-band
default; the "ND"/None path is untouched (already col 1) and a NORMAL
pitched-with-loft roof still takes the §5.11.4 50 mm row (flag defaults
False). roof 76.93 → ~68 W/K → 0240 PE +5.5044 → +1.5181, CO2 +0.2757 →
+0.0728 (SAP integer 72 unchanged — the true value; lodged 73 needs the
unpreserved 2013+ pump).
Also corrects test_u_wall_cavity_as_built_partial_insulation_routes_to_
filled_cavity_row → ..._routes_to_as_built_row: a missed S0380.210
follow-up. That test (in domain/sap10_ml/tests/, which the AGENT_GUIDE §4
suite command does not run) asserted the pre-S0380.210 "partial insulation
→ filled" behavior on legacy-map parity, not worksheet evidence; S0380.210
corrected it to the as-built row per RdSAP 10 Table 6 + golden cert 0390's
four-metric closure.
Suite: 2614 passed, 1 skipped; the 2 remaining failures in
test_rdsap_uvalues.py (stone §5.6 thin-wall formula vs Table-6 1.7 cap)
are pre-existing (fail at HEAD

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
