The paper presents a novel method of generating metamodels that can quantify the influence of urban form on the heating and cooling loads of dwellings for the Mediterranean climate. The goal of the metamodels is to inform the early urban design process with quick and accurate feedback on the energy demand of a given urban configuration. The proposed method generates training datasets through Monte Carlo dynamic energy simulations of a single thermal zone. The study focuses on the geometrical parameters that affect building energy balance at the urban scale, such as dwelling shape, compactness, adjacencies and shading, utilizing a set of morphological indicators to relate these parameters to heating and cooling loads. The study focuses on the Mediterranean climate of Thessaloniki, Greece and utilizes several open-source tools (Ladybug Tools, EnergyPlus and Scikit-learn) under a streamlined workflow. The metamodels, which are trained using the Random Forest algorithm are then validated on 12 real-world urban sites of Thessaloniki with a reported Mean Average Percentage Error (MAPE) of 12% and 15% for heating and cooling loads, respectively.
