This dataset comprises of a PDF with the Vignettes from the stories created during the GEMDev project, in the three informal settlements (Barrio Altos, El Agustino, Jose Carlos Mariategui) in Lima, Peru. The stories illustrate fictional characters of low-income dwellers' household typical day, attempting to be representative of reality. The 17 stories that are presented have been imagined from household surveys, oral histories and Focus Groups that were carried out with the inhabitants of the different settlements. The Excel file contains each story and the analysis that was performed in translating the story naratives to core inputs for multi-domain simulations and urban building energy modelling.
