Measuring Floor Areas in Buildings (II)

GIA and GFA in Spanish Order ECO/805/2003

In Spain, Order ECO/805/2003, on Valuation Standards for Real Estate Properties, includes specific criteria for the measurement of Gross Internal Areas (GIA) and Gross Floor Areas (GFA) in buildings.

Gross Internal Area - GIA

According to the Order ECO/805/2003, GIA is the result of substracting from the floor area bounded by the perimeter defined by the inner face of the external wall of a building -or a building element- the following areas:

• the area occupied by all internal walls and partitions
• the area occupied by vertical structural elements
• the area occupied by pipes or ducts with horizontal section area greater than 100 square centimeters
• the floor area where clear height is smaller than 150 centimeters.

The floor area bounded by the perimeter defined by the inner face of external walls must include 50 per cent of the floor area of all private use covered outdoor spaces (terraces, balconies, drying rooms, porches, loading docks, overhangs, etc.), as measured along the horizontal projection of the roof.

GFA Excluding Common Parts

According to the Order ECO/805/2003, the Gross Floor Area Excluding Common Parts is the result of adding to the floor area delimited by the inner face of the external walls of a building -or element of a building- the following areas:

• 100 per cent of all area occupied by facades
• 50 per cent of all area occupied by sharecropping partitions, or partitions shared with other elements in the same building.

Again, the floor area bounded by the perimeter defined by the inner face of the external walls must include 50 per cent of all private covered outdoor spaces, as measured along the horizontal projection of the roof.

GFA Including Common Parts

According to ECO/805/2003, Gross Floor Area Including Common Parts includes the proportionate share which is result of the application of the associated sharing rate on the floor area of all common elements of the building.
