The Pombaline Quarter Reconstruction Plan of 1758 consists of compact rectangular-shaped dwelling buildings constructed using a system that combines solid mass construction elements with a light wooden frame. Taking into account both the structural and architectural characteristics of the original Pombaline block, it demonstrates the possibility of achieving NZEB level if an energy retrofit strategy at a block scale is executed rather than the traditional single building or portion method. Retrofitting historic structures has prompted concerns about the scope and efficiency of the intervention. The influence on the built heritage must be minimal or non-existent, while energy-related improvements must be visible. This research aims to analyse and compare the results of passive, active, and BIST/PV systems packages deployment on two original blocks in terms of energy demand and primary energy consumption, with the goal of minimising the influence on case studies appearance. The whole-of-building dynamic simulation programme EnergyPlus is used to apply a Building Energy Simulation approach. The findings demonstrate that improving the outside envelope can cut heating and cooling energy demands by up to 50% while also improving thermal comfort. Finally, a combined VRF/Biomass heating solution has the best primary energy consumption statistics, while photovoltaic and solar thermal systems have proven to be critical in achieving NZEB level performance.
