About Total Area

There are many ways to calculate the Total Area of your floor plan. The ways of defining Total Area depend on what factors of the building should or should not be included, such as external walls, internal walls, corridors, lift shafts, stairs, etc. In the RoomSketcher App, you specify what should be included or excluded in the calculation by setting the Area Type for certain zones (rooms).

 

Specify an Area Type for a Zone (Room)

Note: All zones are defined as Area Type=Primary by default, so you only need to set the Area Type when it is different than Primary

  1. Open a project in the RoomSketcher App.
  2. Open Walls mode.
  3. Press to select a zone (room) in your project.
  4. Press Advanced Properties on the right.



  5. Press Area Type.



  6. Choose the Area Type for the zone. Available Area Types are:
    • Primary – All zones are set as Primary by default, so you only need to set a zone's Area Type if you want it to be different.
    • Secondary – used in some countries to indicate that the zone is not a typical living space, for example, closets and storage areas. These can be excluded from some calculations.
    • Outdoor – outdoor areas are excluded from some of the calculations.
    • Exclude – excludes this zone from ALL the calculations.
  7. If desired, select another zone and set it's Area Type. Repeat until you have defined an Area Type for each area in the project.

Example Floor Plan With Area Types Defined



Once you have set the Area Type, RoomSketcher has multiple ways of calculating the Total Area. Many countries have standards defining what is included in the calculation. RoomSketcher includes 6 different methods, which cover the most common standards:

1. Grand Total Area

Area Types: Includes all zones with area types Primary + Secondary + Outdoor

Walls: All walls are included

Translation:

  • da: Samlet Areal
  • de: Gesamte bebaute Fläche
  • no: Bebygd areal (BYA)
  • sv: Byggnadsarea



2. Gross Floor Area

Area Types: Includes all zones with area types Primary + Secondary

Walls: All walls are included

Translation:

  • da: Bruttoareal
  • de: Brutto-Grundfläche
  • no: Bruttoareal (BTA)
  • sv: Bruttoarea



3. Gross Internal Area

Area Types: Includes all zones with area types Primary + Secondary

Walls: Includes all internal walls

Translation:

  • da: Intern Areal
  • de: Brutto-Raumfläche (inkl. Wände)
  • no: Bruksareal (BRA)
  • sv: Bruksarea



4. Internal Zone Area

Area Types: Includes all zones with area types Primary + Secondary

Walls: No walls are included

Translation:

  • da: Intern Rum Areal
  • de: Netto-Raumfläche (ohne Wände)
  • no: Nettoareal (NTA)
  • sv: Nettoarea



5. Secondary Area

Area Types: Includes all zones marked Secondary

Walls: Includes all internal walls in Secondary zones

Translation:

  • da: Sekundær Areal
  • de: Nebenbereich
  • no: Sekundærareal (S-ROM)
  • sv: Biarea



6. Primary Area

Area Types: Includes all zones marked Primary

Walls: Includes all internal walls in Primary zones

Translation:

  • da: Primær Areal
  • de: Hauptbereich
  • no: Primærareal (P-ROM)
  • sv: Boarea


Calculation Notes

  • For Area Type=Exclude, RoomSketcher excludes the zone – not any walls.

Note: The RoomSketcher App is not a full-fledged CAD tool and all measurements are best effort approximations.

 

Calculate the Total Area 

  1. Click or tap Menu (yellow button at the top left), choose Total Area*. Choose one of these tabs:
    • Preview tab – view a color-coded floor plan, to easily visualize the Area Type selection for each zone (room) in your project. The color codes are defined on the right.



      Use the drop down above the floor plan to see a visual of which of your floor plans' zones (rooms) are included in each calculation.



    • Level tab - view the calculations for the CURRENT level (or floor). There is one line for each Total Area Calculation.



    • Project tab - The Project tab shows the sum of ALL levels in the Project. There is one line for each Total Area Calculation.
* Note: The RoomSketcher App is not a full-fledged CAD tool and all measurements are best effort approximations.
 

Add Total Area to Floor Plans
To add the calculation to your project:

  1. In Windows etc mode, press the Magnifying Glass on the right and search on Text, then close the Search box.
  2. Drag the Text Label onto your project.
  3. Type the Total Area number into the Label field.
