Dataset for "On the optimisation of urban form design, energy consumption and outdoor thermal comfort using a parametric workflow in a hot arid zone"

This dataset supports the study on the investigation of urban form design parameters and their relationship to outdoor thermal comfort and energy consumption in Cairo, Egypt. The study utilises Grasshopper for Rhino3D to manage parametric combinations of the urban geometry (Documentation video "Typologies") as such it uses the Ladybug-tools plugins which link Grasshopper with EnergyPlus for energy simulations (Documentation video "Simulation"). The CSV data file includes the input geometrical parameters (prefixed "IN:") and the corresponding output thermal comfort and energy use (prefixed "OUT:").

Data collection method:

TT-Toolbox Colibri Iterator was used to run the simulation of each geometrical configuration consecutively. Upon each run, EnergyPlus calculated the total energy (cooling, lighting electricity and equipment) loads as well as the outside surface temperatures which in turn are used as part of the thermal comfort estimation. Upon each iteration, the Colibri plugin exported the results to the CSV file.
