At the beginning of this year, Professor Jiang Yi, associate dean of Tsinghua University's Department of Architecture in Beijing, was invited to visit Taiwan. He found that most residential buildings in Taiwan are poorly ventilated, and said that installing ceiling fans and air conditioning is pointless. The healthiest solution is to ensure proper ventilation and the exchange of air between the inside and outside of a residence.
今年初應邀來台訪問的中國北京清華大學建築學院副院長江億，發現台灣住宅多半通風不佳，他表示裝吊扇、冷氣是沒有用的，一定要室內、室外空氣對流交換才算健康。
