The main pitched/flat roof U-value was derived from the JOINED text of every roofs[] entry. A room-in-roof carries its own §3.9/§3.10 shell area + U-value cascade (Table 17 / Table 18 col 4), so a multi-roof cert lodged "Pitched, insulated (assumed) | Roof room(s), no insulation (assumed)" leaked the RR's "no insulation" marker into the main roof's u_roof → U=2.30 applied to the WHOLE main roof, ~3x over-stating its heat loss. This is the 4700-family regular-roof-U leak. `_joined_main_roof_descriptions` drops "Roof room(s)" entries before the main-roof u_roof, falling back to the unfiltered join only for pure-RR dwellings (every entry an RR) to preserve their prior behaviour. The RR shell U is unaffected (computed separately) — golden 6035 stays green. RR-leak cluster (18 certs, RR "no insulation" + a non-RR primary roof): mean |err| 6.14 → 4.85, within-1.0 0 → 8, within-0.5 0 → 3. Eval headline 44.8% → 44.9%, mean |err| 1.851 → 1.824, mean signed -0.152 → -0.081. Two certs overshoot (other residuals the leak was masking); the spec rule is applied uniformly.

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
