From: Urban form and economic sustainability in housing projects

Main element Code Indicator How to measure the indicator Data M. Unit Economic Sustainability (ES) Notes
Urban fabric UF Built-up to total space ratio (solid and void) UF1 = buildings ratio = total built-up area/total land area Total built-up area, total land area Percentage (%) There is an inverse relationship between UF1 and ES Compactness index
UF2 = voids (spaces) Ratio = total voids area (spaces)/total land area Total space area, total land area Percentage (%) There isa positive association between UF2 and ES Public and private spaces
Land use LU Mixed-use ratio LU = area designated for mixed-use/ total area Total area, total mixed-use area Percentage (%) There is a positive association between LU and ES Land budget, Entropy index
Density D1 Built-up ratio D1 = total built-up area of the ground floor for land use/land area Ground floor area for all uses, total land area Percentage (%) There is an inverse relationship between D1 and ES Footprint
D2 Population density D2 = population/total land area Population, total land area Person/acre There is a positive association between D2 and ES Residential density
D3 Floor area ratio D3 = total built-up area for all floors per use/area designated for each use Built area for each floor, land-use area for each use Value There is a positive association between D3 and ES FAR
Circulation and road network NR Degree of connectivity and transmittance NR1 = degree of accessibility in the region (NODES) = number of nodes inside the region (connections) Nodes, road links Value There is a positive association between NR1 and ES Beta index
NR2 = degree of accessibility to the outer area = number accessibility points to the main external road External accessibility points Value There is a positive association between NR2 and ES Outer roads, nodes
PT Public transportation network PT = total lane lengths for public transportation/total street lengths Total lane lengths allocated for transportation, total street lengths Percentage (%) There is a positive relationship between PT and ES Public transport
