IFC: 117 stated IfcSpace floor quantities; 100 walls selected by IfcRelSpaceBoundary PHYSICAL/EXTERNAL, area from stated NetSideArea (38 walls without tessellation, 2,048.16 m², inherit the 62 tessellated walls' sector mix); 357.89 m² windows and 27.23 m² doors at OverallWidth × OverallHeight, unsectored so apportioned by opaque-wall share; 13.64 m² ground-slab union; roof priced as the 522.94 m² 5. Sal plate because [L]AC slabs produced no shadow. All 117 rooms are assumed conditioned. Thermal properties, climate and operation are assumptions.
A-CLIMATE · Seoul comparison climate, not a Danish weather series.
Molio-Huset is a Danish IFC-exchange sample. IfcSite address fields are placeholders. The engine currently has Korean regional climates only.
A-ERA-UNDATED · 2010–2019 Korean office tables and 2015 code year; use code 14000; concrete-family structure 21.
The IFC header dates the 2022-11-10 ArchiCAD 25 export, not construction. No construction year is established. 2020+ Korean ZEB tables would flatter an undated sample office.
A-CONDITIONED-SPACES · All 117 IfcSpace are conditioned, including 14 basement rooms (523.74 m²).
Room quantities do not establish operating schedules or conditioned status.
A-ENVELOPE-BOUNDARY · Exterior walls are the 100 IfcRelSpaceBoundary PHYSICAL/EXTERNAL element references; area is each wall's stated NetSideArea.
483 external physical space-boundary surfaces did not resolve as readable polylines. Membership does not require those unread surfaces.
A-ORIENT-SCALE · 38 walls (2,048.16 m²) produced no tessellation. Their facing is not measured. Sector areas scale the 62 tessellated walls by 2.7786 to the 3,199.70 m² stated total.
Assigning those 38 walls a fake +X face would have dumped ~2,000 m² onto east/west. Scaling preserves the measured mix without inventing a facing for walls that have no mesh.
A-WALL-U · Whole-building opaque wall U = 0.35 W/m²K on every sector, the 2010–2019 Korean non-residential table.
The file states no assemblies and no U-value.
A-ROOF · Priced roof area is 522.94 m², the 5. Sal floor plate. 16 IfcSlab named [L]AC and 2 IfcRoof [L]AE produced no plan shadow.
The engine refuses a zero roof. If the real roof is the 99.54 m² 6. sal this overstates roof loss; if it is a full plate this is the right magnitude. PV is not placed on a stand-in deck.
A-GROUND-UNDERSTATED · ISO 13370 on the measured 13.64 m² union / 25.6 m perimeter only. Basement walls priced as outdoor air.
The basement floor plate is 523.74 m²; only three small [L]BG slabs overlap it. A missing slab understates ground loss. The engine lacks a basement-specific model.
A-WINDOWS · 2010–2019 Korean table: U 1.5, SHGC 0.35; VLT 0.5. 357.89 m² glazing is unsectored in the extract and is apportioned by opaque-wall share.
Window hosts among the 38 untessellated walls have no measured sector. A whole-building WWR reproduces 357.89 m² exactly.
A-WWR-ENGINE-MEAN · One whole-building glazing/gross-wall ratio on four orientations.
Host-wall sectors for most windows are unavailable. Project north is assumed.
A-DOORS · 27.23 m² exterior door is priced at the wall U-value and apportioned by opaque-wall share.
The engine has no separate door heat-loss element. 10 IfcDoor confirm against an exterior wall.
A-HVAC · Office-table central gas heating and central chiller; heat-recovery ventilation at assumed 0.7 efficiency and 0.7 ACH; DHW gas boiler 0.85.
Published service geometry is 42 lighting terminals. No HVAC plant is typed. Korean table fuel and COP are comparison assumptions.
A-LPD · Office code-table lighting: 10 W/m² LED with daylight dimming.
42 IfcFlowTerminal luminaires are geometry, not a lighting power density.
A-OCCUPANCY · Office table: 0.1 persons/m², 15 W/m² gains, 10 L/person/day DHW, weekday office hours.
Room names classify spaces; they do not supply an occupancy schedule.
A-AIRTIGHT · 1.5 ACH50, the 2010–2019 table value; the engine divides by 20 to natural ACH.
No blower-door measurement exists.
A-NORTH-FOOTPRINT · Project north; square fallback recipe footprint of area 528.15 m²; no baseline PV.
The model states no true north. Absence of PV in the architectural file does not establish that none exists.
