@ -169,6 +169,34 @@ Pattern: `with E.session() as (ctx,page): E.goto(...); E.set_text/set_select(...
|

lines 17/18). This drove the first campaign mapper fix — see Banked findings.
|
||||
|
||||
## Banked findings (fold new ones in here as the corpus grows)
|
||||
- **Register cost-triangulation (no Elmhurst needed):** the register lodges
|
||||
`heating_cost_current` / `hot_water_cost_current` / `lighting_cost_current`
|
||||
at RETAIL prices — absolute £ never match SAP Table-12 spec prices, but for
|
||||
same-fuel end-uses the RATIOS localize a divergence without a worksheet.
|
||||
Normalize by lighting: `(lodged_hw/lodged_light) / (our_hw/our_light)` ≈ 1
|
||||
means our water cascade agrees with the lodging software; »1 flags the
|
||||
divergent end-use. CAVEAT: the register's "hot water cost" INCLUDES the
|
||||
SAP (64a) electric-shower electricity — add `instant_shower` cost to our
|
||||
hw bucket before comparing on any electric-shower cert, else every
|
||||
shower-outlet-type-2 cert false-positives at ratio ~2 (corpus-1000 band
|
||||
triage, 36 certs, mean ratio 2.0 → 1.04 after adding (64a)).
|
||||
- **Lodging-software conventions diverge from Elmhurst on two known axes**
|
||||
(mark such corpus certs ⚠, don't tune): (a) out-of-range-PSR database
|
||||
heat pumps — SAP 10.2 N2 footnotes 44/45 mandate the reciprocal extension
|
||||
toward 100% at 2× the record's largest PSR (Elmhurst does this, golden
|
||||
case 56); at least one software bills 100% direct electric + standard
|
||||
schedule instead (corpus 4510053280, lodged 51 vs engine/Elmhurst-method
|
||||
75). (b) a lodged 0 extract fans — Elmhurst renders 0 as "unknown" →
|
||||
Table 5 age-band default (worksheet case 46); LIG-21.0 lodgements
|
||||
(calculation_software_version 10.2.2.0) honour the 0 literally (corpus
|
||||
quadruplet at Δ −2.56, fans account for 1.42).
|
||||
- **"insulated (assumed)" roof ≠ observed retrofit:** RdSAP renders
|
||||
"(assumed)" when insulation PRESENCE is an age-band assumption — Table 18
|
||||
age default governs, for BOTH the "ND" and "NI" thickness sentinels
|
||||
(which are lodging-software noise). The §5.11.4 50 mm row (U 0.68) is
|
||||
only for the bare "insulated" description (observed retrofit, depth
|
||||
unknown). Fixed in u_roof (corpus 74.2% → 75.5%); unit-pinned in
|
||||
test_rdsap_uvalues.
|
||||
- **MAPPER GAP — cylinder insulation thickness dropped (RdSAP-17.0+):** the mapper
|
||||
carries `cylinder_size` + `cylinder_insulation_type` but NOT
|
||||
`cylinder_insulation_thickness` → `EpcPropertyData.sap_heating.cylinder_

# Elmhurst validation — UPRN 200004296092 (corpus, slice-5 wall fix)
|
||||
|
||||
Built in accredited Elmhurst RdSAP10-Online on the lodged register inputs
|
||||
(end-terrace house, solid brick + **external insulation, thickness "NI"**,
|
||||
pitched 150 mm loft, solid ground floor, mains-gas combi, TFA 62).
|
||||
Artefacts: `elmhurst_summary.pdf` (Input Summary), `elmhurst_worksheet.pdf`
|
||||
(SAP Worksheets).
|
||||
|
||||
## Headline
|
||||
- **Lodged SAP 71**; **engine 71.74** (post slice-5 §5.4 100 mm fix, was 64.35);
|
||||
**accredited Elmhurst current SAP 66** (band D), potential 75.
|
||||
- Slice 5 is **directionally validated**: the externally-insulated wall must be
|
||||
billed insulated, not at the uninsulated 1.40 the §5.8 gate produced. Both
|
||||
Elmhurst (0.48) and the engine (0.29) are far below 1.40.
|
||||
|
||||
## Fabric line-by-line (engine dive vs Elmhurst worksheet)
|
||||
| Element | Engine | Elmhurst | Note |
|
||||
|---|---|---|---|
|
||||
| External wall | 21.1 W/K (U 0.29) | 30.7 W/K (U **0.48**, "SolidWallDensePlaster**200**") | see WALL below |
|
||||
| Roof | 9.35 W/K (U 0.30) | 9.35 W/K (U 0.30) | **exact match** |
|
||||
| Ground floor | 21.2 W/K | 22.7 W/K (U 0.73) | close |
|
||||
| Party wall | **8.57 W/K** | **0.00 W/K** | see PARTY below |
|
||||
| Windows | 7.96 W/K | ~same area (4.31 + 4×2.89 split) | ~ |
|
||||
|
||||
The wall (engine −9.6) and party wall (engine +8.6) differences nearly cancel,
|
||||
so the two HTCs are close; the residual SAP gap (71.7 vs 66) is dominated by the
|
||||
heating system — this build used a GENERIC Post-98 condensing combi, whereas the
|
||||
engine uses the lodged PCDB 16137 (Ideal Logic combi 30). Not a clean 1e-4
|
||||
comparison for that reason.
|
||||
|
||||
## Leads (both partly confounded by an imperfect build — see caveats)
|
||||
1. **WALL — base thickness on an unmeasured wall.** The cert lodges
|
||||
`wall_thickness 360` but `wall_thickness_measured = N`. Elmhurst modelled a
|
||||
**~200 mm** base wall ("SolidWallDensePlaster200") — but note my build did
|
||||
NOT enter a wall thickness, so Elmhurst used its own default; had I keyed
|
||||
360 mm it might match the engine. The open question is genuine though:
|
||||
RdSAP §5.3 uses the documentary/measured thickness, and when NOT measured
|
||||
the engine perhaps should fall to the Table-3 default rather than trust the
|
||||
unmeasured lodged 360 mm. WORTH A DEDICATED CHECK (build with the thickness
|
||||
keyed both ways).
|
||||
2. **PARTY WALL — NOT an engine gap.** Elmhurst rendered the party wall as
|
||||
"Solid, U 0.00", but the engine's **0.25** is SPEC-CORRECT: RdSAP §5.10
|
||||
Table 15 row 4 ("unable to determine, house") = 0.25. The cert lodges
|
||||
`party_wall_construction = 0` (unable to determine), so 0.25 is right; the
|
||||
Elmhurst 0.00 reflects how my build's party-wall dropdown resolved (a
|
||||
"Solid" masonry party wall, Table 15 row 1 = 0), not the cert's "unknown".
|
||||
Build artifact, not a bug.
|
||||
|
||||
## Build caveats (why the 71.7-vs-66 residual isn't cleanly attributable)
|
||||
- Heating: built a GENERIC Post-98 condensing combi; the engine uses the lodged
|
||||
PCDB 16137 (Ideal Logic combi 30) — different efficiency.
|
||||
- Wall thickness: not keyed into Elmhurst (defaulted 200 mm) vs engine's 360 mm.
|
||||
- Party wall: entered as a resolved type (0.00) vs the cert's "unable to
|
||||
determine" (engine 0.25).
|
||||
So this build's clean, confirmed results are: (a) the ROOF matches exactly
|
||||
(U 0.30, 9.35 W/K), (b) slice 5's DIRECTION is validated (insulated wall, not
|
||||
the uninsulated 1.40). The wall-thickness question (lead 1) is the one genuine
|
||||
follow-up.
|
||||
|
||||
## Slice-5 calibration note (banked)
|
||||
The accredited "External insulation, **Unknown** thickness" selection in Elmhurst
|
||||
produced U 0.48 (≈ a 50 mm equivalent on its 200 mm base), NOT the 0.29 the
|
||||
§5.4-literal "assume 100 mm" gives on the engine's 360 mm base. The 100 mm fix
|
||||
nevertheless matches the LODGED corpus better (MAE 0.658 → 0.647, within held) —
|
||||
lodged assessors typically knew the real (~100 mm) thickness the register then
|
||||
flattens to "NI". Per the campaign rule (engine = lodged is the goal; Elmhurst
|
||||
arbitrates only when lodged can't be explained from register data), the 100 mm
|
||||
fix STANDS; the lodged-vs-Elmhurst gap here is explained by the register's "NI"
|
||||
discarding the assessor's thickness knowledge. But the base-thickness and
|
||||
party-wall leads above are genuine and independent of the insulation default.

|
