This paper suggests some analysis on dynamics of building plots value in Italy. This is an important subject, since the study of changes in plots value in space and time enables the evaluation of urban rent, which is essential for a fair and effective planning. The analysis confirm past hypothesis which are well known to real estate market operators. The first resulting fact is that the changes in building plots value are concurrent to those in real estate value and the increase occurring in the last years is in relative terms higher than the past one.

Nel comparto dell’edilizia, si assiste a un enorme dispendio di energie e risorse. Ciononostante, a fronte di una crescente sensibilizzazione ai problemi dell’ambiente globale, gli operatori di questo comparto hanno individuato anche la necessità di fornire qualche contributo volto ad attenuare concretamente le problematiche ambientali. In un simile contesto, è scaturita l’esigenza di sviluppare BREEAM.

This paper seeks to outline the key aspects of sustainability in the built environment by focusing attention on the LEED® certification system as a “universal” instrument to support the implementation,
management and evaluation of sustainable buildings.
The first part of the paper describes the rapid spread of the LEED certification in recent years as a direct consequence of the capacity of this instrument rating to adapt to specific types of buildings as well as to different climatic conditions and morphological features of the sites.
