The property market and, more specifically, the market of the buildings for service activities typically rates as ìA-Class buildingsî those facilities that meet high quality standards. This definition drawn from financial rating models, is not always sided by a precise, objective and scientific identification of the elements that characterise it. This paper will illustrate the criteria that can usefully determine which variables support a property rating model targeted at the identification of those elements that may define the ìqualityî level of buildings according to performance-based criteria. The research method applied has produced a classification of the most popular and internationally applied systems of building performance rating, based on functional and/or technological criteria. More specifically, this paper describes the assessment domains and the reference context/market taken into consideration by the various rating systems. The research activity has materialized in the identification of the parameters that can be usefully applied to build a ìproperty ratingî model for the service-sector buildings and for the industrial plants used for logistics activities, these parameters being suitable to represent the overall performances of buildings in a synthetic manner.
