History

Khalim Conn-Kowlessar fa5bdcc26f slice S-A2: dimensions module (SAP 10.3 §1) Second slice of the SAP10 Calculator Session A (ADR-0009). Ships a frozen Dimensions dataclass + dimensions_from_cert(epc) pure function under domain/sap/worksheet/. Aggregates geometry across every sap_building_parts entry (main dwelling + each extension): total floor area, volume, storey count, area-weighted average storey height, ground/top floor area, ground-floor heat-loss perimeter, gross wall area, party wall area. Top-level epc.total_floor_area_m2 is the authoritative TFA; per-storey sums drive the wall-area calculations. Volume = TFA × avg_storey_height. 5 AAA cycles cover: single-storey single-part, two-storey scaling, main+extension aggregation, empty-cert fallback to default 2.5 m height, and a non-default-height terrace exercising party-wall scaling. Edge cases (porches, conservatories, integral garages, RIR storey treatment) deferred to later slices per ADR-0009 Session A scope.		2026-05-17 21:49:29 +00:00

domna-domain

Shared domain types — Property, Properties, BaselinePerformance, Plan, PlanPhase, Scenario, ScenarioPhase, ScenarioSnapshot, Recommendation, OptimisedPackage, EpcPropertyData, etc.

Boundary: types only. No persistence, no IO, no business logic. Other packages and services depend on domna-domain; this package depends on nothing internal.

Domain definitions live in ../../CONTEXT.md. New types added here must match the glossary terms.
