Areas

On the Areas tab, you can enter all the necessary data for the areas of the individual object parts. Data can be entered at complex, building or tenant level, or you can use the auto function.

Total floor area (TFA)

The total floor area is defined as the sum of the floor areas between the external walls on all floors of the building, excluding uninhabitable cellars and separate unheated spaces.

Gross Floor Area (GFA)

Gross floor area is defined as the total floor area including external walls.

Gross lettable area (GLA)

Gross lettable area is defined as the gross floor area excluding the floor area of corridors and other shared spaces.

Energy reference area

The energy reference area is defined as the area of the internal thermally treated space, which is defined by the external surfaces of the building envelope.

Example: we want to show the amount of energy used to heat one square meter of the total floor area of Building A. For this calculation, you need to fill in the TFA (Energy Reference Area) entry in Parameters -> Areas
