Resumen
The purpose of this research was to create a framework of indicators that enabled us to measure the classic dimensions of sustainable development (SD): People, Planet, and Profit, in combination with the sustainability of the heritage values and the policy dimension. Methods developed as an approach to sustainable urban planning and that were based on system analysis models were modified, streamlined, and adapted into a concrete set of indicators for historical city sites. This framework, a multimodal system which maps out the holistic sustainability could serve as an incentive from the policy to the heritage world to implement sustainable objectives; and it could be used as an extra argument for the broader social relevance of heritage care.
