Numerical study of buoyancy natural convection in open building rooms has been performed using Lattice Boltzmann Method (LBM). The right wall of the room is open, bottom is hot and the other walls are adiabatic. Numerical results are presented in terms of isotherms, streamlines and average Nusselt number to investigate the effects of various Rayleigh numbers and aspect ratios on heat transfer and fluid flow. It is concluded that as the aspect ratio decreases maximum rate of heat transfer happens when Rayleigh number increases.
