摘要：Present the natural ventilation design for the New East-Main Building of China Academy of Building Research (CABR) at the corridor linking Building A and Building B, theoretical calculation during the design phase, and field measurements after the building's completion. The theoretical analysis show that indoor air change rate can reach up to more than 4.4 h(-1) as long as temperature difference between indoor and outdoor greater than 1 or outdoor air velocity greater than 0.4m/s, so that could remarkably improve comfort during the transitional seasons in Beijing; but the field measurement results show 3.37 h(-1) when temperature difference is 1.2 and outdoor air velocity is about 0.3 similar to 1.5m/s, which tells a considerable difference compared to the design value, which has a greater impact on the air exchange efficiency of the room. The author conducts a comprehensive analysis of possible factors, and obtained preliminary conclusions and recommendations. (C) 2016 Published by Elsevier Ltd.
