Energy efficiency as a protection tool.

Summary

The relationship between renovation, system engineering and environmental technical physics is at present not as developed as the one between renovation and full accessibility needs, that is the elimination of architectural barriers, or better still between renovation and structural consolidation works. As a matter of fact, the latter, in the past forty years, has been subject to deep changes which resulted in a new scientific approach and new methods which are translated in wide spread practices that are by far more respectful than was the case in the mid twentieth century. This progress has meant that technical operations have undergone a real “historicization” to respond to a “critical” reason, more than to a technical one, in view of the issue at stake, renovation and cultural objects. It can be stated that these studies resulted in a less abstract, less mathematical approach, yet not less rational or scientific, to address the issue of ancient wall structures, which entailed a better and deeper insight into what they are like and what their function is, with an improved familiarity with these structures. This new approach allowed the development of innovative consolidation works able to preserve the well-rooted “historicity” of the structures, without prejudice to the safety requirements for the monuments, the people and the objects contained in them. Meanwhile, within the framework of the relationship between renovation-system engineering, there is a considerable delay under many points of views including legislation, even though a process of revision and a new disciplinary approach has been under way in recent years: at first, with respect to system engineering issues, with the intention of linking it to renovation concepts and methods; nowadays, with respect to the efficient use of energy, the theme of renewable energy sources sustainability etc. On this point, the concept of “improvement” as opposed to the one of “adjustment”, employed in the field of structural consolidation, with excellent results for cultural objects and their protection, can now at last be applied also to system engineering and energy issues. This approach will have to be confirmed by the fact that attention paid to “energy efficiency” in a historic building can indeed contribute to protection: firstly, because it translates into a more accurate and measured design of the required solutions; secondly, because “energy efficiency” is an essential component of a sound and not expensive economic management of historic buildings, to the advantage of their viability and enjoyability.
