Proposal of a methodology for achieving a LEED O+M certification in historic buildings

The certification process results, at a first analysis, hard to follow due to the complexity of internal parameters and the documentation required. The paper consists in a methodology and in an univocal work program of LEED O+M, trying to obtain the minimum requested certification score with optimization of the technical resources and documents. This methodology has application in a case study of historic building: the Ca' Rezzonico Museum, in the center of Venice.
