Pre-evaluation of indoor chemical pollutants in green building: Research progresses and suggestions

The conception of green building comes out along with the concern and attention of sustainable development of buildings. Indoor air quality is an important part of green building. How to built a healthy, suitable and energy saving building becomes a hot social and research topic of the world, especially in China. As the main source of VOCs indoor, the emission character of VOCs from building materials and furniture influences indoor air quality directly. In order to predict the pollutant concentrations indoor, we must know the emission character firstly. Therefore, this paper introduces models of VOCs emission and measurement methods to determine the emission characteristic parameters. Some possible problems during pre-evaluation of indoor air quality and related suggestion are also proposed in this paper.
