Integrated methodologies energy efficiency of historic buildings

ABSTRACT

For several years, Italian associations and research organizations have been developing strategies aimed at evaluating and increasing energy efficiency in historic buildings, offering a sort of guidelines about this issue. These strategies are intended to provide useful information for a correct approach to the energy retrofit of historic buildings, offering a framework as well as innovative technical solutions for integrated design intervention restoration of historic buildings. The purpose of the guidelines is investigating the relationship between architectural restoration and plant installations, which are – now – rarely explored problems theoretically and experimentally, by introducing the concept of improvement instead of adapting to the standards of safety and comfort, in accordance with the integrated conservation strategies (Amsterdam Declaration, 1975). Effective proposals of a historic building energy retrofit (or a cultural landscape) can be implemented in a conscious way, tending to an architectural and landscape integration, without changing the monumental building, as it often happens in the case of adaptation of a new building to the new rules. The proposed methodology is based on an interdisciplinary approach, articulated in successive phases: analysis of plant systems, measurements of environmental quality, identification of vulnerabilities, defining appropriate intervention techniques, verification of the improvement achieved. The case study concerns a historic building in Salerno (Italy) dating back to the eighteenth century, used as a school complex. It will be investigated by the morphological, technological, static, energy point of view, by the use of a BIM platform, in order to identify energy efficiency measures consistent with the technological and structural aspects. The objective is, therefore, to identify an integrated methodology of energy retrofit of historic buildings.
