Simulation of thermal comfort on public space and buildings around river in Banjarmasin-Indonesia

Abstract

Abstract The climate and environmental aspects are one of the things that affect architectural products. The city as a gathering place that interacts for a particular purpose has influenced the shape and visual of the city. The density of buildings in a city has affected the urban microclimate. Urban get hotter than rural areas. Urban planners need to pay attention to several aspects related to the solution to the design of the humid tropics. The concept of greening the city evenly and thoroughly, so that the thermal is not too high that can affect comfort. In this research used Rhinoceros 5, Grasshopper, Ladybug, and ladybug for simulation and validation data of wet bulb temperature on a psychometric chart and CBE Thermal Comfort Tool from ASHRAE-55 standard. The purpose of this study used simulation is to facilitate and predict the thermal conditions of buildings and the environment. This application is also used by researchers and architect designers. Based on the simulation, the indoor maximum effective temperature and standard effective temperature are always uncomfortable zones. The building condition with wooden construction is higher of thermal comfort compared with concrete construction buildings and the wood construction is faster reaches maximum value compared to concrete construction.
