Retrofit design SARD framework

This chapter is organized as follows. In section State of the Art an overview of the state of the art on sustainable retrofit design tools and metrics is presented. In section Framework for Assessment of Retrofit Design Alternatives the strategic sustainable assessment of retrofit design (SARD) framework is presented with a step-by-step description. A case study is presented in section Case Study p-Galactosidase Production to highhght the application of the framework. Finally, conclusions are drawn in section Conclusions. 

A framework called SARD, intended to guide the decision makers in their retrofit design assessment, is presented in this section. Fig. 11.4 presents the flow diagram of sard s steps.

After classifying the retrofit design actions (step 2), the decision maker should determine the most suitable level of analysis detail for assessing the retrofit designs. For that purpose, the SARD framework proposes a three-layer evaluation for the assessment of retrofit designs.
