Abstract: Mean Radiant Temperature (MRT) is a critical physical quantity that indicates how human beings experience radiation in their surrounding environment. If taken outdoors, MRT depends on the temperature of the sky, ground, vegetation and surrounding buildings, and is therefore difficult to predict reliably. An additional challenge for designers is that publically available simulation tools do not produce reliable outdoor MRT outcomes within a design environment. Hence, this paper presents a raytracing-based simulation methodology for spatially and temporally resolved MRT mapping and consequent outdoor thermal comfort assessment. Following a description of the simulation workflow, the method is applied to a case study of an outdoor space in Syracuse, NY, USA.
