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.

Central LondonSelected component

Fills albedo. The record declares target land_cover.bldgs, name 'Central London', place london, representativeness site, applicable_scale land_cover, source ward2016 and method fitted.

BuildingSelected component

Fills emissivity. The record declares target land_cover.bldgs, name 'Building', 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 declares target land_cover.bldgs, name 'Building', place generic, representativeness generic and applicable_scale land_cover.

High Rise Million Program, mid 1900sSelected component

Fills construction. The record declares target construction, name 'High Rise Million Program, mid 1900s', place sweden, representativeness regional and source bjork2002, and its outermost wall layer is records/materials/generic--unreferenced--concrete-tiles at 0.08 m.

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 the summer_wet, summer_dry, winter_wet and winter_dry ohm slots. The record declares target ohm_coefficients, name 'Roof (own for SMEAR III, Helsinki) [750]', place helsinki, representativeness city, source unreferenced and method calculated, and carries no season_label.

Assessment findings

Composite identitysupported
The name field of the composite reads 'Concrete (Million Program)', its place field sweden and its origin field Sweden. The construction slot takes records/constructions/sweden--bjork2002--high-rise-million-program-mid-1900s, whose own name reads 'High Rise Million Program, mid 1900s' and whose outermost wall layer is records/materials/generic--unreferenced--concrete-tiles at 0.08 m. The label and the selected construction agree on both the building programme and the material, which is the check the sibling archetype archetypes/surfaces/bldgs/sweden--brick-house-traditional-neighbourhood fails.
Composite targetsupported
The composite declares target land_cover.bldgs, which agrees with its position under archetypes/surfaces/bldgs. 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 four ohm slots take a record declaring target ohm_coefficients. records/ohm/helsinki--jarvi2014--buildings declares no season_label and no wet or dry distinction, so filling summer_wet, summer_dry, winter_wet and winter_dry with the one record is the only mapping its content supports. None of these records declares attaches_to, which in this database appears only on the profile and snow-profile records, so the SUEWS field each slot writes is fixed by the slot name alone and cannot be cross-checked against the component.
Own parameter valuesnot applicable
The composite declares no parameters block, so it overrides no component value.
Composition rationalenot applicable
The composite claims no composition source, and the repository records no published rationale for assembling these particular records into a Swedish Million Programme concrete typology. The sources of the components belong to their own evidence assessments, not to this review.
Place applicabilitycuration required
The composite claims Sweden. Construction is the sole Swedish component and declares place sweden. Albedo declares london; OHM declares helsinki; emissivity, water storage, drainage and snow_lim_patch are generic. The London albedo choice and predominantly non-Swedish assembly remain the curation questions.
Representativenesscuration required
The regional composite has one regional construction, one site albedo, one city component, OHM, and four generic components, emissivity, water storage, drainage and snow_lim_patch. The narrower evidence used in this national-scale composition remains a curation decision.
Slot and season mappingsupported
An assembly of existing records into slots; the composite produces no value of its own.
Completeness and uniquenesssupported
All seven slots are filled, and the four ohm slots take one record, consistent with records/ohm/helsinki--jarvi2014--buildings declaring no season_label. No other archetype in the repository carries an identical uses block, and no other archetype uses records/constructions/sweden--bjork2002--high-rise-million-program-mid-1900s. Within the Swedish buildings family this entry shares its other six components with archetypes/surfaces/bldgs/sweden--brick-house-traditional-neighbourhood and differs from archetypes/surfaces/bldgs/sweden--nordic-functionalism-wood in the albedo slot as well as the construction, so the construction is the intended axis of variation and it is honoured here.

Scientific note

The one slot that carries the identity of this typology is right. records/constructions/sweden--bjork2002--high-rise-million-program-mid-1900s is a Swedish record, classed regional, named 'High Rise Million Program, mid 1900s', with concrete tiles as its outermost wall layer, so the label, place and scale of the composite all hold for the component that actually distinguishes it from its siblings. Everything else is borrowed. OHM is a Helsinki city row; emissivity, snowpack_limit, water storage and drainage are generic; and the albedo is records/surfaces/bldgs/london--ward2016--albedo, a Central London site row. Two consequences follow. The composite claims regional but has one regional, one site, one city and four generic components, so a national default rests on city measurements, which is not correctable inside the composite and needs either a narrower class or country-scale rows that do not yet exist. And the albedo selection is the one borrowing that was not forced: two generic archived configurations with Gothenburg lineage exist, Wood and 'Industry, dark roofs', neither describing a concrete-tile facade, and no file records why the London row was preferred to either. Both points recur across the Swedish buildings family and should be settled once for the family. This review does not revisit any component value.
