Abstract(s)
The reuse of existing materials in buildings can give a contribution to sustainable practices
such as a balance in embodied energy, water, and emission reduction. However, it is not always
possible to maintain the existing structural materials because some different technical variables
could hamper their usability, namely seismic reinforcement needs, fire safety protection, conservation
state, and new legal requirements. The paper follows a case study approach for assessing the
technical and environmental performances of structural options for old building retrofitting works.
All structural options were analyzed through the results of several categories of environmental
impact. Some parameters of a retrofitting management system were also used to frame in a comprehensive
way the technical constraints pertaining to building retrofitting works. The structural option
choice was taken by the owner with the contribution of the design team and the construction manager
of the construction project as well as the results of interviews with other construction professionals,
considering the variables related to technical suitability and environmental impact. The results of
the study show that the steel structure is the solution that best addresses the technical constraints
of the building retrofit works and minimizes environmental impact. The results of the study also
suggest that the consideration of other variables other than the technical ones can contribute to the
effective functioning of the renovation subsegment of the building market. Some suggestions for
further studies to enhance the results of this work are put forward.
