1-1 General Principles for Green Building Materials
1. General Requirements
(1) A green building material shall possess no potential for environmental impacts during its life cycle, including resources acquisition, manufacturing, transportation, and utilization. The manufacturer of a green building material product shall receive no penalties for violation of environmental regulations issued by local competent authorities within a specific period prior to the application.
(2) The function and performance of a green building material product shall comply with its corresponding national standards if applicable, or international standards in case of lack of national standards. Otherwise, the compliance of relevant regulations or principles from identifiable sources shall be presented.
(3) The quality and safety of a green building material shall comply with relevant regulations.
2. Prohibited Substances
The evaluation on prohibited substances for green building materials is aimed to limit the hazardous material contents. In order to ensure a healthy and safe living space and ecological environment, the evaluation system identifies and classifies the hazardous substances endangering human health and environment (key pollutants) and determined relevant criteria based on types of materials with quantitative analysis and controlling regulations.
The evaluation items of prohibited substances are listed as follows:
(1) Limitations on heavy metal ingredients of a non-metal material following the Toxicity Characteristic Leaching
3
Procedure (TCLP) for industrial wastes listed in Table 1-1.
(2) No asbestos.
(3) No radioactivity (Gamma dose rate less than 0.2 mSv per hour limit).
(4) No toxic chemical susbstances announced by the EPA (listed in Table 1-2), whereas the 003 asbestos, 066 formaldehyde, and 052 benzene and phthalic acid among the list shall comply with the criteria established in the green building mateirla evaluation system.
(5) No inorganic halide or other chemical compounds according to Montreal Protocol (CFC, halon, etc), listed in Table 1-3.
(6) Chloride ion less than 0.1% for cement-related products, according to the CNS 14164-7.10.3 testing methods.
(7) Plasticizer less than 0.1% by weight for the materials with PVC contents, according to the CNS 15138 test for phlatic acid esters.
(8) Materials for interior finishes with concerns of TVOC and HCHO emissions ascertained by the designated evaluation organization shall undergo TVOC and HCHO testings listed above. The emission rate shall be less than 0.19 mg/m2∙hr for TVOC and 0.08 mg/m2∙hr for HCHO.
For the prohibited substances, an applicant shall address the test report prepared by any of the accredited green building material testing organizations designated by the Ministry of the Interior (MOI). If there is no designated organization for some items, an applicant may address the test report from the accredited laboratory complying with the Sections 1 to 3 of Article 2 of the “Operational Directions for Applying for Designated Green Building Material Testing Organization.” Among the prohibited substances, an applicant shall address the valid test report from an MOI-designated organization for items (1), (2), (3) and (8), and may provide the declaration for items (4) and (5) with its Material Safety
4
Data Sheet (MSDS) for further examination. The applicant is legally responsible for the information on the declaration and MSDS. As for items (6) and (7), an applicant may address the test report from the accredited laboratory complying with the Sections 1 to 3 of Article 2 of the “Operational Directions for Applying for Designated Green Building Material Testing Organization.”

Notes:
1. FSC documentation: The principles and criteria defined by the Forest Stewardship Council include (1)
compliance with all applicable laws and international treaties; (2) Demonstrated and uncontested, clearly defined,
long–term land tenure and use rights; (3) Recognition and respect of indigenous peoples' rights; (4) Maintenance
or enhancement of long-term social and economic well-being of forest workers and local communities; (5)
Equitable use and sharing of benefits derived from the forest; (6) Reduction of environmental impact of logging
activities and maintenance of the ecological functions and integrity of the forest; (7) Appropriate and continuously
updated management plan; (8) Appropriate monitoring and assessment activities; (9) Maintenance of High
Conservation Value Forests (HCVFs); and (10) plantations must contribute to reduce the pressures on and promote
the restoration and conservation of natural forests. (Source: http://www.fsc.org)
2. PEFC documentation: Founded in 1999, the PEFC is now the world’s largest forest certification system. The PEFC
certification provides forest owners and managers with independent recognition of their responsible management
practices and with access to the consumption market of certified products. Developed by the Ministerial
Conference on the Protection of Forests in Europe with 37 participating countries in 1993, the understanding of
Sustainable Forest Management (SFC) is defined as “the stewardship and use of forests and forest lands in a way,
and at a rate, that maintains their biodiversity, productivity, regeneration capacity, vitality and their potential to
fulfil, now and in the future, relevant ecological, economic and social functions, at local, national, and global
levels, and that does not cause damage to other ecosystems." (Source: http://www.pefc.org)
