Marchetti & Pasquinelli - input2012

  1. 1. Development rights management through GIS technology: the case study of Melzo (Milano) Matteo Marchetti, Alice Pasquinelli POLITECNICO DI MILANO
  2. 2. ASSUMPTIONSOptimization of existent resources aimed to prevent waste of new soilUrban equalization mechanism: equal treatment of properties and freeacquisition of areas for public servicesTransfer registry in order to manage volume transfer from public areas tobuilding lotsPurpose: Detection of residual volumes generated by the urban plan insidethe perimeter of the urbanized territory
  3. 3. STEPSDefinition of proper units of inquiryDelimitation of the study areaChoice of the analitycal sampleDefinition of the procedureData analysis and results
  4. 4. UNITS OF INQUIRY 5 1 1 4 2 3Italian 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.
  5. 5. STUDY AREA
  6. 6. STUDY AREAApartment blocks,medium-high density
  7. 7. STUDY AREADetached and semi-detached houses,medium-low density
  8. 8. STUDY AREAProject based texture medium-high density medium-low density
  9. 9. ANALYTICAL SAMPLE Inclusion of areas of appurtenance belonging to all four kinds of urban texture Uniform covering of the study area Analysis of a sufficient number of appurtenances with respect to the total number of appurtenances of the whole area
  10. 10. PROCEDURE EVALUATION OF RESIDUAL VOLUMES DATA CAPTURING Urban parameters and Surface data indexes DATA PROCESSING Calculation of Calculation of existing volumes realizable volumesStatistical projection yes Volume no No residual resources on the study area surplus?
  11. 11. PROCEDURERESIDUAL VOLUME = REALIZABLE VOLUME – EXISTING VOLUME Land Surface * Land Index * Virtual Height Data sources : Gross Floor Surface * Virtual Height LAND REGISTRY for surface data URBAN PLAN: for indexes and parameters
  12. 12. PROCEDUREGross Floor SurfaceSum of all surfaces of floors, outside and underground, included in the perimeter ofthe building envelope (walls, windows, doors…). Some surfaces can be inlcuded or notin this parameter and the urban plan provides a long list of specific criteria which haveto be followed for its computation. Urban real Room type Descriptionestate typology Main rooms A (bedroom, kitchen, corridor, toilet and bathroom, , box room, internal stairs) Addictional rooms directly accessible from the main rooms Residential B (i.e. cellars or attics connected to the main rooms by internal stairs) Addictional rooms NOT directly accessible from the main rooms C (i.e. cellars or attic connected to the main rooms by external stairs or external access)
  14. 14. ANALYSIS AND RESULTS *Gross floor surface including just main rooms Mean residual volume 323 in a single area of appurtenance [m3/appurtenance] Mean residual volume 0.77 in a square meter [m3/m2] *Gross floor surface including main and addictional rooms Mean residual volume 130 in a single area of appurtenance [m3/appurtenance] Mean residual volume 0.31 in a square meter [m3/m2]
  15. 15. CONCLUSIONSResidual resources detection and optimization without wasting newsoilNew dataset for administrative management of volumes and propertiestransfer related to the urban equalization mechanismIntegration of the geographical information with Land Registry data
