Global climate change is demanding Architects to embrace regionalism and traditional architecture in their designs. The objective of this paper is to analyse design works of renowned Architects who made use of the vernacular architecture features at different region towards developing passive cooling. The study aims to inform an architectural style from the vernacular houses of Kerala which incorporates thermal comfort of users, passive solar features, site planning, spatial organization, and material and construction technique. The study is comprised of four stages. The first stage was to study the architectural style of Kerala and understanding its uniqueness and cultural dependency along with its climatic reliability. Secondly, a database of the research is established from secondary sources, by collecting works of architects from different geographical locations having similar climate zone, economic background and cultural ethnicity. In the third phase, works of the architects were compared for similarities, dissimilarities and limitations to understand the most effective methodology.
