The Green Building Evaluation Manual-Basic Version (EEWH-BC) is an update of the Evaluation Manual for Green Building, the original assessment system in Taiwan. The Manual has gone through seven revisions, with this edition being the eighth to correspond to the launching of the EEWH Family. Its new name, Basic Version, refers to its role as the source of the EEWH assessment theories and the foundation of all other Manuals. Assessment for residential buildings such as single- and multi-family housing was extracted from the original Evaluation Manual for Green Building to form the EEWH-BC. The extracted section for assessing housing is now an independent and dedicated system called the EEWH-RS. Compared with the more specialized EEWH-RS, EEWH-GF, EEWH-RN and EEWH-EC systems, the EEWH-BC applies to more complex building types including air-conditioned buildings, schools and large-scale buildings.
