SAP 10.2 Table 12a Grid 1 (PDF p.191): electric storage heater SAP code 408 is an "Integrated (storage + direct-acting) system" with a 0.20 space-heating high-rate fraction on a 7-hour tariff — NOT the 0.00 of "other storage heaters". `_table_12a_system_for_main` returned None for all storage codes (an explicit TODO), so code 408 fell back to the 100%-low-rate path and billed space heating at the bare 7-hour low rate (5.50 p/kWh) — under-costing → over-rating. Mapped cat-7 storage: 408 -> INTEGRATED_STORAGE_DIRECT (0.20), others -> OTHER_STORAGE_HEATERS (0.00, unchanged behaviour). The enum + fraction rows already existed; this only wires the dispatch, so the split flows self-consistently to both the §10a cost and the Appendix-M1 D_PV high-rate fraction. Corpus: sap408 over-raters +14.6/+12.9/+12.7 -> +7.1/+5.1/+3.4 (two crossed into within-0.5). Gauge 65.9% -> 66.1%, MAE 1.160 -> 1.128. Floor 0.63 -> 0.64 / MAE ceiling 1.22 -> 1.18. Worksheet harness 47/47 0 diverge. The residual +3..+7 is the "all other uses" 0.90 high-rate fraction (lighting/pumps/HW still billed 100%-low on the off-peak legacy path) — the next slice.

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
