Study of thermal comfort in the Sentra Primer Barat CBD Area using envi-met simulation

Abstract

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.
