At present, there are several spatial analyses tools available for analyzing the spatial properties of the built environment. Spacematrix' focus is on various types of density on the urban block...

Oct 1, 2017 · Gross space index (GSI) and floor space index (FSI) are two of the most common density indicators. They describe respectively the compactness and the intensity of buildings in the urban textures. The GSI is defined as the ratio of the built-up area to the urban site area; the FSI is the ratio of the gross floor area to the urban site area.

The diagram relates the FSI (Floor Space Index) in axis y, GSI (Ground space index) in axis x, OSR (spaciousness), and L (average number of building storeys) in the diagonal axes. For example, the Traditional-Be has a sample whose FSI values range from 1 to 3,5, GSI from 0,35 to 0,75, L from 2.5 to less than 5 storeys, and OSR, from less than 0 ...

GSI - Ground Space Index; which gives information about the relation between built and open space. The lower the index is, the more open space there is in the area. OSR - Open Space Ration; which gives information about the spaciousness and pressure on the open space. A high FSI ensures a low OSR.

Spacematrix' focus is on various types of density on the urban block such as FSI, GSI, OSR (or spaciousness), network density (N) and the number of floors (L).

Dec 15, 2024 · To enhance energy efficiency, urban planners should consider increasing the (FSI) and (GSI) while managing the (OSR) to balance heating and cooling demands. Patterns with moderate (FSI) and (GSI) and higher (OSR) generally result in lower cooling demands and more efficient energy use.

Ground coverage or Ground Space Index (GSI) values are calculated from building footprints and land boundaries. The Spacemate tool, devised by Berghauser Pont and Haupt, is used to plot the types and ages of dwellings in terms of FSI, GSI and numbers of storeys.

The Spacemate model relates together four geometrical properties to segregate building types numerically: density expressed as floor space index (FSI), ground coverage or ground space index (GSI), spaciousness expressed as open space ratio (OSR) and number of storeys (L).

... our renewed approach, the GSI corresponds to the ratio between the building's footprint area and the corresponding Voronoi diagram's cell area. The second one is the floor space index...

Urban quality can be partly quantified in parameters like Floor Space Index (FSI - intensity), Ground Space Index (GSI - compactness), Open Space Ratio (OSR - pressure on open space) and height. The density and the morphology of the urban fabric can be adequately described by these parameters, using plot charts where the different parameters ...
