Thirty-eight experts from 12 different IEA countries attended the meeting. The traveler represented US involvement in the Subtask 1 of the Annex 20 to attend the meeting. The studies of room air and air contaminant distribution conducted in the Bioenvironmental Engineering Research laboratory (BERL) at the University of Illinois, Urbana-Champaign, were summarized, and the activities of other US researchers were highlighted. International participants expressed a need for experimental data in one of the specified test cases (case d: free convection room flow) in Annex 20 to compare with the numerical simulation results already obtained by three different IEA participating countries, and hoped that the US will conduct this experiment with the Room Ventilation Simulator available at BERL. No other participating countries have the facilities to conduct the test. Numerical simulation and experimental measurements previously conducted by different countries for the other four test cases were compared and discussed and future work outlined. Topics of particular interest included the measurement of low air velocity in the occupied zone, the measurement of air velocities within the flow boundary layer over the ceiling of wall surfaces, modeling diffuser air jets, and non-symmetry and low turbulence characteristics of the ventilation flow.
