Dataset for "Multi-objective optimisation of urban courtyard blocks in hot arid zones"
This dataset supports the study on the relationship between the design parameters, namely, individual building heights, interspaces, and orientation, and both outdoor thermal comfort and cooling loads of urban courtyard blocks in Cairo, Egypt. The study uses Grasshopper for Rhino3D and its environmental plugins, Ladybug-tools, as well as the multi-objective optimisation plugin, Octopus, to analyse thermal comfort represented by the Universal Thermal Climate Index (UTCI) along with cooling loads in MWh of thousands of courtyard block configurations. The data files include the raw data as produced by the search algorithm, and recorded in Grasshopper, the refined data excluding duplicates, data for the Pareto optimal sets, as well as the processed data.

Data collection method:
Simulations were setup in Grasshopper, where the plugin Octopus was used to iterate the simulation of each courtyard geometrical configuration, and the Ladybug-tools to calculate the objective functions. Grasshopper components, "Data Recorder", were used to record the recursive data iteratively throughout the 3 types of simulations. Upon the end of each phase, the data was manually transferred (copy-pasted) to CSV files by the researcher. For the data files, types A, B, and C refer to courtyard's width elongated 1, 2 and 3-fold its length. The annotation "dup" refers to the entire sample produced by the algorithm, which contains duplicate solutions. The annotation "exc_dup" refers to the refined sample after excluding duplicate solutions. The annotation "Pareto" refers to the best performing solutions in the refined sample in terms of both objective functions (UTCI and Cooling loads), also known as the Pareto front solutions. The xlsx file includes all the data in the 9 files, along with their analyses and visualisations.
