Colour model
A Monthly final energy hourly engine · indicative · kWh per month
B Energy through the year colour = dominant use · darkness = demand
C Annual cost split
D Energy & cost
E Too-hot hours by month hourly ISO 13790 (5R1C) · free-running first
F Overheating through the year month × occupied hour · months align with E
G Operative temperature weekly max and mean vs the comfort limit — hover for values
H Summer comfort building summary — select rooms for the per-room table
Passive first — the 5 % rule

A room is acceptable free-running when at most 5 % of occupied hours exceed the comfort limit (EN 16798-1). Before adding cooling capacity try, in order: exterior screens, night ventilation, more exposed mass, less glass — every change re-simulates the year instantly.

I Daylit floor area climate-based Perez sky · Radiance-validated engine
J Daylight availability mean workplane lux, month × hour
K Daylight per room
Assumptions

Reflectances: ceiling 0.8 · walls 0.7 · floor 0.3 · frame fraction 80 %. LTA is set in the Building fabric card. Movable shading is ignored for daylight (GRO convention); LM-83 blind operation is not modelled — treat sDA as indicative. Neighbouring rooms and tagged surroundings block light.

P Material impact by element TOTEM-style mPt · sample values pending the TOTEM API
Q M-peil class
R Elements & buildups
S Buildup library feeds the dropdowns under Building fabric → Materials

Element values are mPt per m² of element over the building's life, TOTEM-style sample data — import real TOTEM results via ⬆ Import (JSON or one buildup per line as name;element;mPt); a live TOTEM API connection is planned. Surfaces come from the scan: interior walls count once (each shared face at 50 %), storey floors count slab + ceiling as one buildup from the room above, technical systems follow the Systems choices.

L Overview — all spaces one row per space · scroll sideways for more · blank = program default
⬆ Import spaces from Excel — generate the rooms in the model…

Tick rows to select those rooms in the 3D view and bulk-edit them in the sidebar selection card; selecting in SketchUp highlights the rows here. Space names are editable — they rename the SketchUp group. Cooling capacity, comfort category and daylight targets are building-level settings under Systems.

M Heating NBN EN 12831 static per room · hourly & EnergyPlus results beside it
N Cooling design-day static per room · hourly comfort & capacity beside it
O Ventilation unit sizing · flows · ducts · natural potential

Transfer openings: door undercuts or grilles of ≥ 25 m³/h per internal door (≥ 50 m³/h to the kitchen); ≈ 70 cm² free section per 25 m³/h. Natural potential: Warren–Parkins stack; operable share set under Systems → Automated windows.
