The paper is an addendum to the paper entitled "Ancient vernacular architecture: characteristics categorization and energy" that was published at "Energy and Buildings" in 2010 [1]. This addendum provides an explicit list of 114 codes representing vernacular architectural regions across the whole globe defined by climate, culture and continent. Codes are intended to support work in analyzing and memorializing vernacular building characteristics that otherwise may be lost. This addendum will be an important and useful resource for analyzing and studying vernacular architecture. (C) 2015 Elsevier B.V. All rights reserved.
