In Italy, according to report (2014)  drafted by Carlo Cottarelli, former spending review Extraordinary Commissioner,  the Public Administrations use approximately 79.29 million square meters, of  which 81% are state-owned and the remaining 19% owned by private or public  entities. For the latter, the total expense for leases is estimated at 1,215  million Euros.
The art.2, paragraph 222, Law No.191/2009 has advocated to  rationalization spaces used for institutional purpose, attributing to Agenzia  del Demanio the task of developing a rationalization space plan, both for  State owned and buildings owned by third parties. The law requires State Administrations  to communicate their space need and the spaces that are no longer needed.
Furthermore, Agenzia del Demanio must match  the needs objectives of reduction of public expendi-ture: ensuring the  existence of properties to be assigned in use among those owned by the State or  among those transferred to real estate investment fund (art. 4 Decree No.351/2001),  verifing the adequacy of the rent and choose the economically most advantageous  tender, and also, considering the decentralisation of offices.
By paragraph 222-quarter, the Legislature  forced all administrations to submit their national rationalization plan. It  includes: the respect of the parameter per employee (20/25 square meter),  efficiency on territorial presence by sharing public building available and  abandonment of lease properties. The public aim is to ensure a reduction of 50%  for cost of lease and not less than 30% for space used.   
According to the report  by Cottarelli “Razionalizzazione utilizzo  immobili. Prime conclusioni del gruppo di lavoro sulla razionalizzazione  dell’uso degli immobili e della riduzione delle locazioni passive” shows that  (excluding the Ministry of Defense) only 60% of public administrations occupy  real estate owned by the State while the remaining 40% pays a rent. This trade off costs € 1,215 million.
Former Commissioner proposes to revise the  geographical distribution of public administration, taking, where possible, the  state-owned properties. Following the plan of Cottarelli property used by the  state should be reduced by 20 percent, while the costs would be cut down by 30  percent, merging different branches of public administration.
The report excludes the Ministry of Defence  which occupies two-thirds of the property owned. It follows that the remaining  public administrations meet their need for space in 60% of cases with property  for government use and the remaining 40% with privately owned. In addition, from data sourced from  PA-Ratio shows that ca. 56.5 mln sqm of gross area and 773.6 mln sqm are assigned to  Government for institutional purpose.
According to Agenzia del Demanio data, cost  of lease is equal to 915 mln of which the 33% may be subject to reduction of  50% by the rationalization plan (Decree Law No. 191/2001). Agenzia del Demanio  expects to save from 2015 to 2019 ca. 10 mln from renegotiation or neglect of  FIP-FIP1, 103 mln from review rents and Ministero della Difesa rents.
The central  Government’s goal is to reduce costs of lease through the containment of space  used.
In order to achieve this objective, the law  requires every single Local Public Administrations to assess their need space  (by quantitative standard: 20/25 square meter) and to propose their strategies  based on a set of options:
The  knowledge of public real estate assets is an indispensable factor to realize  the efficient assets management and its profitability development, in order to  maximize the collective interest and to reduce the public debt.
The  analysis and knowledge of assets are based on a qualitative and quantitative  information made up for financial needs and for a proper heritage recognition. In  addition, it must be considered that an inadequate knowledge level implies the  risk of a non-recognition of the potentialities of the existing assets \citep{articlep}. The information required, in order to make decisions, are often inadequate.     
Deloitte report "Municipal real estate. Comparing public real estate management in European cities" shows that in 2011 about 30% of major European cities are able to  provide data on the amount and value of their public real estate, and while, most  organizations had a basic property inventory, it is often incomplete,  inaccessible and also difficult to implement.
This  assumption is valid for Italian context too. The census has involved only Central Public Administrations such as:  Avvocatura dello Stato, Mef, Agenzia Fiscale, Ministero degli Interno, MIUR,  MIPAAF, Ministero della Giustizia, Ministero delle Infrastrutture e dei  Trasporti, MISE, Ministero dell’Ambiente, Ministero del Lavoro e delle  Politiche Sociali, Ministero della Salute, MIBACT, Presidenza del Consiglio dei  Ministri and Ministero della Difesa. But, this public administration list is incomplete with the number of  public administrations, which means that data is partial.
Currently, according to Agenzia del Demanio  data, cost of lease is equal to 915 mln for use of about 9.800 buildings, of  which 27% relatives to FIP-FIP1 fund, 40% used by Ministero della Difesa and  remaining 33% of properties are subject to rationalization plans.

At present, planned projects are 185:  rationalization project are 95, Federal Buildings are 37 and merger projects  are 53.
