By 2045, it is estimated that almost 70% of Indonesia’s population will live in urban areas. However, the growing population and density of the city of Jakarta has led to a significant increase in temperature, which has a negative impact on the comfort of living in the region. Sentra Primer Barat CBD is one of the strategic central business districts in Jakarta. The purpose of this study is to identify the condition of thermal comfort in the Sentra Primer Barat CBD Area in two conditions, the current conditions and the planned conditions. The planned conditions are adapted into instructions on urban design guideline for Sentra Primer Barat. The study uses ENVI-met software to analyse thermal comfort. Microclimate parameters that are used for the study are air temperature, wind speed, humidity, and Tmrt (Temperature Mean Radiant). The parameters will then be reviewed and utilised to see their implications for thermal comfort index. The results shows a significant difference between the current conditions and the planned conditions. Under planned conditions, there is an increase in average air temperature and Tmrt, while average wind speed and average humidity see a decrease. This indicates higher potential of thermal discomfort in the study area. The thermal comfort index (PET) also deteriorate under the planned conditions. This research highlights the importance of improving thermal comfort in the Sentra Primer Barat CBD Area and provides guidance for better urban planning in the future. It is expected that environmental improvement efforts in this region can improve the residents’ quality of life and promote sustainability of the urban environment.

使用环境模拟研究 Sentra Primer Barat CBD 区域的热舒适度

到 2045 年，预计印度尼西亚近 70% 的人口将居住在城市地区。然而，雅加达市不断增长的人口和密度导致气温显着升高，这对该地区的生活舒适度产生了负面影响。 Sentra Primer Barat CBD 是雅加达战略性中央商务区之一。本研究的目的是确定 Sentra Primer Barat CBD 区域在两种条件下的热舒适度状况：当前条件和规划条件。规划条件已纳入 Sentra Primer Barat 城市设计指南的说明中。该研究使用 ENVI-met 软件来分析热舒适度。用于研究的小气候参数包括气温、风速、湿度和 Tmrt（平均温度辐射）。然后将审查和利用这些参数来了解它们对热舒适指数的影响。结果表明，当前条件与计划条件之间存在显着差异。规划条件下，平均气温和Tmrt上升，平均风速和平均湿度下降。这表明研究区域存在更高的热不适可能性。在计划条件下，热舒适指数（PET）也会恶化。这项研究强调了改善 Sentra Primer Barat CBD 地区热舒适度的重要性，并为未来更好的城市规划提供了指导。预计该地区的环境改善工作可以改善居民的生活质量并促进城市环境的可持续发展。
