Abstract

Urban Heat Island (UHI) mitigation research has been carried out for a long time but it requires to be sharpened to enrich mitigation strategies. In Bandung, maximum temperature has been increasing from 330C to 350C in 30 years. Bandung is getting hotter which can exaggerate the negative impact of UHI mainly in the downtown area. Suitable UHI mitigation strategies are needed to lower urban temperature. UHI mitigation has involved the use of heat-absorbing and covering man-made materials with vegetation such as green wall and roof system. Content analysis of UHI precedents and some preliminary studies are applied to assess prerequisites of UHI mitigation. The analysis showed adaptation opportunities of UHI mitigation strategy on buildings and environmental physical components. The mitigation strategies may vary depending on the typology of buildings (roof and wall) by using reflective materials, while outside the building by increasing vegetation to maximize evaporation to lower the temperature.

Highlights

The increased in human activity as well as rapid development of built area causing the increasing temperature in urban area called urban heat island (UHI)
In certain areas, the building utilization likely to be multifunctional building and there are pockets of densely settlement that surrounded by commercial areas. Those problems emphasize that the implementation of UHI mitigation strategy in Bandung becomes more difficult when compared to the city with the uniform building mass and have good spatial planning
The components that are observed include physical components that should be intervened by implementation of UHI mitigation

Summary

INTRODUCTION

The increased in human activity as well as rapid development of built area causing the increasing temperature in urban area called urban heat island (UHI). UHI mitigation strategy must suitable with urban design elements especially mass and building form; green space; preservation area, and pedestrian walk. Remote sensing study from LANDSAT data stated that the UHI areas (areas with surface temperatures above 300C) at the Bandung basin had been expanded in 1994 to 2001 due to the rapid changes in land cover (Tursilowati, 2005). In certain areas, the building utilization likely to be multifunctional building and there are pockets of densely settlement that surrounded by commercial areas Those problems emphasize that the implementation of UHI mitigation strategy in Bandung becomes more difficult when compared to the city with the uniform building mass and have good spatial planning. Buildings and pavement in the city area are composed by heavy materials that absorb heat and have a low albedo value. Based on literature review preceding UHI mitigation research and theory of urban design elements, the study has obtained the requirements of mitigation strategy application as mentioned on Table 1
