Windows are still the thermally weakest part in considering energy efficiency. The vacuum glazing is considered as a new alternative in terms of energy efficiency. Vacuum glazing are consisting of two separated glass, pillars are support the under and upper glass. Therefore in this paper suggested the pillar shapes and array arrangements method using Finite Element Method and validity were proved by comparing and analyzing with the research that it is announced through the existing experiment. It is considered to solve pillar shapes and arrangement method problem of the vacuum glazing using proposed FEM analysis.
