Urban growth and development are associated with a very rapid increase in urbanization. This event has an impact on climate change, especially the microclimate. Microclimate is a climatic condition that can be felt directly by humans and affects the comfort of activities in an area. The Jalan M. H. Thamrin corridor is the most densely populated part of the central business district (CBD) with the leading high-rise building structure in Indonesia. Based on data on the number of Transjakarta passengers in 2020 passing through this corridor, around 28,166,094 people, planning for the intensity and massing of buildings in this corridor must pay attention to the quality of the thermal environment in the outdoor space. Therefore, this study will conduct a design evaluation to determine the level of thermal comfort in the corridor along with mitigation strategies to improve its quality. This research will conduct a design review using a quantitative deductive research method using ENVI-met and SPSS software tools. Simulation and regression methods are used to analyze the climatic and physical parameters that have the most influence on each building typology and their correlations. The results of the study found that the sky view factor (SVF), which is formed from the asymmetrical H/W ratio, is the most influential urban physical parameter for thermal comfort. KDB and KDH have correlation with wind speed, relative humidity and air temperature. Meanwhile, KLB only has a correlation with wind speed and relative humidity. The conclusion of this study states that the Predict Mean Vote (PMV) thermal comfort index in microclimate will be achieved by reducing building density, increasing building height, and increasing open space.
