KAKS / Emsal (Floor Area Ratio)

KAKS (Floor Area Ratio) or, as it is commonly known, Emsal, is the ratio of the total net construction area that may be built on a plot to the plot area. For example, if Emsal is 1.50 and the plot is 1,000 m², the total construction area of all floors of the building may be at most 1,500 m² (1000 x 1.50).
