This study describes the software functions of Chronolux Sketch Up plug in. This software aims to simulate insolation at some point. Insolation areas and sky view factor (SVF) which is integrated as where the initial phase of a design process at an analysis site. Chronolux is proven as the simple tool to help a designer to know the grade of insolation, which then decided the vegetation spot based on the level insolation. Based on this experiment, it is known that north part area is an area with maximum insolation within 10 hours, and west part area is an area with the minimum insolation within 7 hours. From the SVF calculation, it is found that the north part with 77.28% later can reduce the SVF until 42.69% by optimize the placement and determine the characteristic of vegetation. After the placement of vegetation, the solar insolation then is able to reduce from the average 6h5m into 4h35m . The vegetation then is proven as an important aspect to reduce the insolation.
