etageareal

Etageareal is a Danish architectural term referring to the floor area of a building. It is used in planning, construction, and real estate to express the size of usable spaces on individual floors or across the entire building. The term is often translated as floor area and is closely related to but distinct from related concepts such as gross floor area and net floor area.

Measurement practices vary by jurisdiction and standard. In many contexts etageareal is measured on the finished floor level, bounded by interior faces of exterior walls, but some standards use outer bounding lines or inner faces of structural elements. Tall atria, mezzanines, and multi-level interconnected spaces can complicate calculations, and partial floors may be prorated according to standards.

Common uses include calculating building occupancy metrics, energy performance, property valuation, and rent or sale pricing. Engineers and architects may report etageareal alongside height, number of floors, and volume to give a complete picture of a building's size.

For comparative purposes, it is important to specify whether the figures refer to gross or net floor area and to cite the applicable standard or regulation used in the measurement. This helps ensure consistency in planning assessments and real estate transactions.
