Climate sensitive urban design is an important design approach to respond a climate condition on an urban area which has an increasing temperature phenomenon. Temperature rise in an urban area will lead to urban heat island phenomenon which has an impact on outdoor thermal comfort. The CBD BSB City Semarang master plan is a commercial area with a high intensity floor area ratio is at risk to encounter urban heat island. A design review with climate sensitive urban design approach is needed to cope with the circumstance, anticipate microclimate issues and to achieve an outdoor thermal comfort condition within the master plan. The purpose of this study is to perform a design review with climate sensitive urban design approach to assess the CBD BSB City master plan and ensure an outdoor thermal comfort condition. Design review uses an ex-ante evaluation time orientation. Ex-ante evaluation is an assessment of a program before it is implemented. This study is calculating numerical variable of microclimate such as air temperature, wind speed, relative humidity, and mean radiant temperature with ENVI-Met software to understand the outdoor thermal comfort based on the thermal comfort index which is PMV and PET. To achieve outdoor thermal comfort in CBD BSB City Semarang, strategies are needed to adjust the planned master plan such as to arrange buildings orientation to East – West or North East – South West, arrange street orientation to North West – South East, place the highest building in North West side and gradually place the lowest building in South East side, form a street corridors with more than 1.50 value of aspect ratio, utilize a dense tree with big trunk with spherical tree profile, and finally position green open spaces scattered across the site.
