In the present paper a methodology is proposed to evaluate the sustainability of intervention in existing multi-storey concrete buildings using structural steel systems. Taking into account that an intervention in an existing building can be characterized as sustainable if the design considerations include critical sustainability assessments, a method is proposed and then applied to a case study for the restoration of an eight-floor building located at the center of the city of Thessaloniki. This case study is also compared to other relevant assessments with the option of reuse of the existing building only with elementary restoration works and the design of a new composite steel-concrete building constructed at the same location. The analysis includes a description of the building characteristics and pathologies, with an estimation of the structural performance after the application of an optimization process when using structural steel systems for its enhancement.
