In the previous report, the authors solved an attic air distribution using vorticity method. However, vorticity method can\u27t be expanded to three dimensional problems. Since an indoor air distribution should be analyzed by three dimensional models from the practical point of view, \u27\u27SIMPLE\u27\u27 method is introduced here to directly solve the Navier-Stokes equations. Although the principal conception of \u27\u27SIMPLE\u27\u27 method is the same as that of \u27\u27MAC\u27\u27 method, it is verified that the \u27\u27SIMPLE\u27\u27 method has several advantages such as the simplicities in the finite difference equation and in the boundary conditions
