More detailed modeling may be required to achieve an optimum design in minimizing exhaust re-entrainment impacts.<br /> <br /> Building designers can compare the dilution estimates furnished by the DDC to dilution criteria to judge acceptability, or use the dilution values to furnish &#039;concentration at intake&#039; estimates.";
