Matteo Marchetti, Alice Pasquinelli
Optimization of existent resources aimed to prevent waste of new soil
Urban equalization mechanism: equal treatment of properties and freeacquisition of areas for public services
Transfer registry in order to manage volume transfer from public areas tobuilding lots
ASSUMPTIONS
building lots
Purpose: Detection of residual volumes generated by the urban plan inside the perimeter of the urbanized territory
Definition of proper units of inquiry

Italian Codice Civile (art. 817)
APPURTENANCE:
an object intended to serve or decorate another main object: the rights overthe appurtenance are recognized to the owner of the main object or towhom holds any rights on the main object.

STUDY AREA
STUDY AREA
Apartment blocks, medium-high density
STUDY AREA
Detached and semi-detached houses, medium-low density
STUDY AREA
Project based texture medium-high density
medium-lowdensity
ANALYTICAL SAMPLE
Inclusion of areas of appurtenancebelonging to all four kinds of urbantexture
Uniform covering of the study area
Analysis of a sufficient number ofappurtenances with respect to the totalappurtenances with respect to the totalnumber of appurtenances of the wholearea
PROCEDURE
EVALUATION OF RESIDUAL VOLUMES
Surface data Urban parameters and
indexes
DATA CAPTURING
Calculation ofexisting volumes
Calculation ofrealizable volumes
Volume surplus?
Statistical projectionon the study area
yes no No residual resources
DATA PROCESSING
RESIDUAL VOLUME = REALIZABLE VOLUME – EXISTING VOLUME
PROCEDURE
Land Surface * Land Index * Virtual Height
Gross Floor Surface * Virtual HeightData sources :
LAND REGISTRY
for surface data
URBAN PLAN:
for indexes and parameters
Urban realestate typology
Room type Description
PROCEDURE
Gross Floor SurfaceSum of all surfaces of floors, outside and underground, included in the perimeter of
the building envelope (walls, windows, doors…). Some surfaces can be inlcuded or not
in this parameter and the urban plan provides a long list of specific criteria which have
to be followed for its computation.
estate typologyRoom type Description
Residential
AMain rooms
(bedroom, kitchen, corridor, toilet and bathroom, , box room, internalstairs)
BAddictional rooms directly accessible from the main rooms(i.e. cellars or attics connected to the main rooms by internal stairs)
CAddictional rooms NOT directly accessible from the main rooms(i.e. cellars or attic connected to the main rooms by external stairs or
external access)
ANALYSIS AND RESULTS
ANALYSIS AND RESULTS
Mean residual volume in a single area of appurtenance [m3/appurtenance]
323
Mean residual volume in a square meter [m3/m2]
0.77
*Gross floor surface including just main rooms
in a square meter [m3/m2]
Mean residual volume in a single area of appurtenance [m3/appurtenance]

Mean residual volume in a square meter [m3/m2]

CONCLUSIONS
Residual resources detection and optimization without wasting newsoil
New dataset for administrative management of volumes and propertiestransfer related to the urban equalization mechanism
Integration of the geographical information with Land Registry dataIntegration of the geographical information with Land Registry data
