Sustainable development is a method of resource management, the effect of which not only meet the needs of the present but also of future generations. Historical monuments as part of national heritage are a resource, which is protected not only in the sense of its cultural value but also has a potential for the creation of socio-economic values. The process of extending the life cycle of a historic building is associated primarily with the analysis of the options for its conversion in the light of various criteria, many of which have a fuzzy character. The aim of the paper regards the proper selection and also description of the criteria for assessing conversion options for historic buildings in the context of sustainable development.
