ABSTRACT

Today built heritage conservation should consider constantly changing needs of users. In particular, recent problems related to the economic crisis and to environmental pollution make issues related to consumption reduction and environmental impact particularly important.

Even if historical buildings have many sustainable features in terms of embodied energy and land consumption, they don’t perfectly meet current standards and impose many restraints from a constructive and typological/functional point of view.

In recent years a new approach to preservation has been derived from the theory of “care of monuments” by Ruskin: a preventive and constant maintenance, interpreted as less destructive and cheaper intervention and management of the continual becoming. Besides a lifecycle approach leads to reconsider management and to rethink the intervention putting in place a balance between positive and negative contributions in the long term.

The LCA mantra “from cradle to grave” is usually applied to new products taking into account all components, from the extraction/production of raw materials to the disposal of constructive elements. Since the main goal of historical buildings' conservation is to shift to infinity their dismissal time, this study aims to lay the foundations for an innovative approach for sustainability assessment of existing buildings that should consider the resources savings and doesn’t set a time limit for the building’s life.

The paper focuses on “minor” built heritage, the most exposed to abandonment and decay.
