The study proposes and compares low-cost strategies to improve the quality of existing building stocks, with special regard to a widespread Indian residential typology. A dynamic energy model of this particular local building typology was simulated with Energy Plus software and validated by comparing it with some original in situ measures, recorded by hourly step. The validated model was used to simulate a selection of low-cost and technically simple interventions, whose effects on the energy performance and indoor comfort were compared to the baseline case study. Comfort performances have been evaluated using comfort indoor degree hours (CIDH) and the TSI index. A combination of the most effective solutions was proposed and simulated. The results were used to assess possible improvements of comfort (reduction of CIDH) and savings of energy consumption (referred to an A/C scenario). Finally, the role of occupants’ behaviour was further investigated.
