Abstract

Construction of buildings causes vegetation, trees, and soil to change into concrete (building) and asphalt (road) and impact on the increase of radiation heat in the surrounding environment. Trees absorb heat energy, can decrease the environmental temperature through shade canopy and evapotranspiration process. The process of reducing the temperature becomes a necessity in an urban area with a hot humid climate filled with buildings like the city of Jakarta. This paper discusses the results of research that aims to determine how effective the role of trees in lowering the ambient temperature around the building. The object of this study is a building that received a green certificate from GBCI in particular that received a high appraisal for the sub-criteria of Appropriate Site Development / Site Landscaping and Heat Island Effect. The research was conducted using field temperature measurement method, simulation of calculation and heat visualization with Infrared Thermal Imaging tool. The analysis is done by comparing the measurement data, simulation, and visualization between several variables under study.
