Description	The paper deals with the assessment of results from an improved form of the standard k-? model for buoyant room flows. This improved k-? model is based on the generalized gradient diffusion hypothesis of Daly and Harlow (1970). Results from the computations for three-dimensional flow are compared with temperature measurements performed by the authors in a laboratory room with displacement ventilation. The numerical results show a good agreement with the laboratory experiments, superior to the results from the standard k-? model. The improved k-? model showed also a better convergence behaviour than the standard k-? equation model. It is quite easy to implement it in every code.
