Sun intensity is different according to its angle of radiation. North and south or east or west of a building will receive different solar intensity. The radiation also affected by the inclination of the surface where sun radiates. Thus, the effect of the different configurations is investigated. The radiation intensity for the collector and canopy in the on-roof solar chimney is different since the material used is different which resulted in different temperature. This difference in temperature will be a significant effect in analyzing the output of the solar chimney. The methods and analysis are done using Computational Fluid Dynamics (CFD) software such as GAMBIT and FLUENT. The analysis was also done for three cases with different configurations. Case 1 consists of Configuration 1 (trimmed-inlet) and Configuration 2 (flat-inlet). The configurations were analysed with two options of temperature distribution, Option A (same temperature for left and right side of roof) and Option B (different temperature for left and right side of roof). Case 2 have two different heat transfer consideration for the collector either conduction or convection and is analysed for three different inlet diameter. Case 3 is solar-biomass integration chimney configurations. From the simulation particularly from FLUENT, the outlet velocity is different for different geometry configurations and operating conditions.
