Abstract: This paper presents a case study of outdoor thermal comfort simulation to support the design of an outdoor space. The outdoor space studied is a courtyard located in a hot arid climate that is expected to be too warm for a portion of the year. A pipeline of tools is presented to predict the thermal stress of occupants in the courtyard using simulated environmental variables and the Universal Thermal Climate Index (UTCI). This pipeline is then deployed systematically to provide guidance for the design team to design a more comfortable courtyard space. Through this case study, we provide a model for the integration of simulation in the design process that serves to support rather than to diminish the role of the designer. The analytical approach is based on a decision tree with multiple design paths, with each node of the tree relating to a design decision. In this way, the analysis systematically walks through a series of design decisions engaging the designer in potential trade-offs rather than simulating all potential combination of parameter values to determine a single mathematically optimal solution.
