Composition

This composite is assembled from the entries below. Each evidence record keeps its own scientific review; a separate composition review assesses why these components were selected and how they are mapped.

Composition provenance

Curation required

Assembled · assessed by provenance-audit · 2026-08-23. Agent assessment is composition review preparation, not human verification.

WoodSelected component

Fills albedo. The record is named Wood, declares target land_cover.bldgs, place generic, representativeness generic, source unreferenced and method assumed; Gothenburg survives only as origin history.

BuildingSelected component

Fills emissivity. The record is named Building, declares target land_cover.bldgs, place generic, representativeness generic, applicable_scale land_cover, source jarvi2011 and method literature.

BuildingSelected component

Fills water_storage. The stable Helsinki-path record declares target land_cover.bldgs, name Building, place generic, representativeness generic, applicable_scale land_cover, source jarvi2011 and method literature. Its Helsinki origin preserves migration/application lineage; the value is published as a generic Building parameter.

BuildingSelected component

Fills drainage. The record is named Building, declares target land_cover.bldgs, place generic, representativeness generic and applicable_scale land_cover.

Mixed-City, 2000sSelected component

Fills construction. The record is named 'Mixed-City, 2000s', declares target construction, place stockholm and representativeness city, and layers roofing shingle, wood, gypsum and mineral fibre slab in its roof and gypsum, mineral fibre slab and wood in its wall.

BuildingsSelected component

Fills snow_lim_patch. The stable path and origin retain Helsinki migration lineage, while the record declares target land_cover.bldgs, name 'Buildings', place generic, representativeness generic, applicable_scale land_cover, source jarvi2014 and method literature, and carries snowpack_limit. It is the only buildings snowpack_limit record in the database.

Roof (own for SMEAR III, Helsinki) [750]Selected component

Fills ohm.summer_wet, ohm.summer_dry, ohm.winter_wet and ohm.winter_dry. The record is named 'Roof (own for SMEAR III, Helsinki) [750]', declares target ohm_coefficients, place helsinki and representativeness city, and declares no season_label.

Assessment findings

Composite identitycuration required
The composite is named Mixed-City and the construction it selects, records/constructions/stockholm--bjork2002--mixed-city-2000s, is named 'Mixed-City, 2000s', so the label matches on that slot. The albedo slot takes records/surfaces/bldgs/gothenburg--oke1987--albedo--wood, a generic archived record named Wood, while the construction this same composite selects describes a fabric of roofing shingle, gypsum, mineral fibre slab and wood in which wood is one material among several rather than the defining one. The composite therefore asserts a wood surface in one slot and a mixed fabric in another, and nothing in it reconciles the two. Whether the wood albedo is the intended selection for a mixed-city typology is a maintainer's decision, not one this review can make.
Composite targetsupported
The composite's own target, land_cover.bldgs, is right for a building-surface typology, and every slot takes a component declared for it: the albedo, emissivity, water_storage, drainage and snow_lim_patch slots each take a record declaring target land_cover.bldgs, the construction slot takes a record declaring target construction, and the ohm positions take records declaring target ohm_coefficients. No record under records/surfaces/bldgs or records/ohm declares attaches_to, which in this database is carried only by the profile records, so slot fit here is judged on the components' declared target.
Own parameter valuesnot applicable
The composite declares no parameters block of its own, so it asserts no value beyond the components it selects.
Composition rationalenot applicable
The composite claims no composition source, and the repository records no published rationale for this selection. The components' own sources belong to their evidence assessments, not to this review.
Place applicabilitycuration required
The composite claims Sweden. Construction declares stockholm; OHM declares helsinki; albedo, emissivity, water storage, drainage and snow_lim_patch are generic. The non-Swedish and default substitutions remain a curation decision.
Representativenesscuration required
The regional composite rests on two city components, construction and OHM, and five generic components; none is regional. Their national-scale use remains a curation decision.
Slot and season mappingsupported
An assembly of existing records into slots; the composite produces no value of its own. records/ohm/helsinki--jarvi2014--buildings fills all four ohm positions, so the composite draws no summer/winter and no wet/dry distinction, and that record declares no season_label of its own.
Completeness and uniquenesssupported
All seven slots are filled and the composite remains distinguishable: it differs from archetypes/surfaces/bldgs/sweden--detached-houses-wood and from archetypes/surfaces/bldgs/sweden--nordic-functionalism-wood only in the construction slot, and that is the slot carrying the typology's identity. No second mixed-city composite exists.

Scientific note

The construction slot is the one that does its job here: records/constructions/stockholm--bjork2002--mixed-city-2000s is named 'Mixed-City, 2000s' and is Swedish. Two things about the rest need a maintainer. The first is the albedo. The composite takes records/surfaces/bldgs/gothenburg--oke1987--albedo--wood, a row named Wood, which is also what the two wood typologies in this family take, while the construction it selects describes shingle, gypsum, mineral fibre slab and wood together. Nothing in the composite says why a wood albedo represents a mixed-city surface, and this review will not infer a reason from the fact that sibling composites make the same choice. The second is scale: the composite declares representativeness regional, yet two components, the Stockholm construction included, declare representativeness city. The Helsinki OHM record is the only Finnish component; emissivity, snowpack_limit, water storage and drainage are generic, since no Swedish record exists for any of those quantities, but that too is unstated. All of this lives in the composite and none of it requires a component value to change.
