Abstract

This paper investigated and evaluated outdoor thermal comfort and walking comfort
in the hot-humid city in Jakarta. This paper used two approaches to show the valid result,
through the field measurement of thermal comfort and simulation of the walking comfort
of Indonesian people. The simulation of walking comfort was used to calculate how far an
individual might be able to walk before experiencing discomfort in an outdoor environment
in the hot humid city. Mega Kuningan-superblock in Jakarta, the first superblock developed
in Jakarta, was the study area. The interesting factor why this superblock chosen
was the compact design. The thermal comfort indices used The Physiologically Equivalent
Temperature (PET) calculated using Rayman Software. Walking comfort indices used skin
wettedness to simulate the physiological of body that react to environment and use the
information to define how far an average Indonesian people can walk while keeping thermal
comfort. The three condition were made during simulation, shaded area, light shaded
area, and open area, to promote different possibilities of thermal conditions. The results
show thermal comfort was difficult to be achieved during the daytime. The heat trapped
amongst the buildings in the nighttime affect the temperature in the morning, thus made
Tmrt rise significantly during the daytime that affect thermal comfort in next day. Tmrt
did not only affect the thermal comfort in open space, but also affect the walking comfort.
Shadowing affects the walking distance, the four minutes walking distance or 320 m average
is the propose to revise the standard of facilities placement in the urban design.
