In the subtropical climate of Taiwan, indoor building materials have a significant impact on the poor indoor air quality, which leads to health problems and increased risks of cancer. Currently, the “Green building materials labels” and the Indoor Air Quality Act have been promoted to control the source of pollution, namely the fugitive pollutants of the building materials and the air concentration in the indoor space. Emphasis is placed on the advanced administrative control of the Total Volatile Organic Compounds (TVOC) to reduce the harm that could be caused by the fugitive pollutants of the indoor building materials to health. This study adopted the fugitive emission database of 645 pieces of the building materials with a green label, test, and verification of the fugitive emission of the seven small pieces of the building materials, numerical statistics and analysis, and literature analysis to research the control of the evaluation factors of fugitive TVOC from green building materials in Taiwan. The purpose of this is to prevent other toxic Volatile Organic Compounds (VOCs) from affecting the indoor air quality, effectively controlling the harm to residents, reducing the energy consumption of the air conditioning for removing pollutants through ventilation, and reducing the carbon emissions, and protect the environment.
