Integrated policies for retrofitting historical buildings are crucial to face the extreme temperature changes prospected in the 2015 Paris Agreement and UN 2030 Agenda. Historic sites need to meet emerging environmental demands while preserving their values and cultural identities. Intervention in historic sites should be adequately quantified and planned in simulated environments, which demand combined computational approaches. This research addresses the building energy performance analysis before and after the design of energy retrofit solutions under the expected climatic conditions in 2030-2100 in Portugal, using advanced parametric modelling tools (Rhino/Grasshopper/EnergyPlus) and a multicriteria decision analysis (M-MACBETH). A set of energy retrofit solutions are automatically scored in different design scenarios. Each scenario differs for the weights assigned to each criterion (i.e., energy consumption, weight, carbon footprint, and impact on architectural configuration) that reflect the preference of the decision-makers or contexedbased priorities. The methodology is tested for assessing the most effective solutions that can maximize building energy performance, usability, and cultural value and minimize the environmental impact. The limited number of solutions tested in this research and the impossibility of using an extended baseline period are the main research limitations, which are discussed in parallel with the opportunities of the proposed method.
