How to read this page
room shows observed built density: what has been built on the parcels, not what the zoning permits. Volume utilization (ratioV) compares the built volume of a parcel with the reference volume of its municipal zone type. The floor-area ratio (GFZ) is floor area divided by parcel area; building height and number of floors are taken from the buildings on a parcel. Figures pool all municipal zones of the area. Medians and quartiles are read from bins 10 points (ratioV), 0.1 (GFZ), 2 m (height) and 1 floor wide, so they are exact to within one bin; means are exact. A parcel counts in a distribution only when the parcel data has a value for it. The floors distribution leaves out parcels without a building (0 floors).
