Abstract: The mean radiant temperature (T mrt) is among the most important factors affecting thermal comfort. Its assessment in dense cities has been complicated due to the presence of buildings, pavings, and infrastructure. This paper introduced the RAMUM model, a GIS based software method developed to simulate outdoor mean radiant temperature at microscale. The advantages of this method lie in its efficiency and resolution that supports the design of buildings, streets, and public open spaces. The model is evaluated using field measurements under cold and warm weather in Boston. This study is sponsored by the EFRI-1038264 award from the National Science Foundation (NSF), Division of Emerging Frontiers in Research and Innovation (EFRI).
