Khalim Conn-Kowlessar 5cc68ab3fd §4 slice 2: hot_water_other_uses_monthly_l_per_day (line (42c)m)
Appendix J equation J11 — daily hot water use for non-shower / non-bath
purposes (sinks, dishwashers, etc.) is annual-avg V_d,other,ave = 9.8 ×
N + 14, modulated month-by-month by the Table J2 monthly factors and
reduced by 5% when the dwelling meets the 125 L/person/day water-use
target.

Validated against both Elmhurst non-RR fixtures to better than 1e-3 L:
  - 000490 N=2.1468 → V_d,other,ave ≈ 35.04, Jan = 38.5426
  - 000474 N=1.8896 → V_d,other,ave ≈ 32.52, Jan = 35.7697

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.
