The paper mainly applied Z300Xp formaldehyde tester and chemical method recorded the data of the indoor formaldehyde concentration of the office and lab with 5-years decoration time and a newly-decorated conference hall. The result shows that chemical method has low detection limit, and the result of the two methods are comparable; the formaldehyde concentration of rooms which were decorated five years ago was under the detection limit. The newly decorated hall being closed for 24 hours can make indoor formaldehyde out of limit, while being opened for 6 hours can reduce formaldehyde concentration within the first kind of standard. The paper concluded that the release amount of formaldehyde became greater with longer confinement time and higher temperature. Advice is given that reasonable collocation of decoration materials and consideration of ventilation is necessary. Also, confinement time should be longer. Key words: formaldehyde
