The SPINE project aims at the use of energy efficient technologies and materials into the renovation of historical buildings with an eye to the various issues and constraints linked to the preservation of authenticity and artefacts in buildings. In a period of shrinking public budgets, replicable and efficient solutions should be shared among stakeholders of all the countries involved. In this paper will be illustrated the first results of the SPINE project and in particular will be illustrated preliminary guidelines and proposals for the renovation of some case study building located in Vladimir (Russia). The description of these preliminary proposals will be associated with the introduction of two different Italian restoration projects which experience has been useful to develop the preliminary restoration hypothesis.
