Infrastrutture di Dati Territoriali e Knowledge Management nella relazione fra mercato e sostenibilità.

The present paper, following the previous issue (Territori, n. 10), refers to the topic of energy policy which plays a fundamental role in the government orientation, at international and European level. It is assumed that the e-government politics success in every European Country, nowadays, is necessarily due to the use of operational systems pointed to consciousness and support of interoperability based decisions, accessibility facts and interaction between different individuals. Therefore we try to consider the possibility of implementing the Real Estate Observatory of the city of Turin shifting from TIS to LIS and, finally, to SDI. We can do this beginning with the scale of the building (the physical features of the constructions, with a special regard to the architectural elements that are very important from the energetic point of view, the noticed energy consumption, the energy certification’s data, the real estate values). All these elements are useful to analyse the energy conditions of urban property. In order to contribute to the administrative choices, we propose a range of analysis instruments based not only on traditional statistic models, but also on advanced statistic spatial models, improving the test and check of actions such as the sustainable energetic re-qualification, from an economic point of view.
