In this paper the basic and applicable concepts of thermoelectric effect has been introduced which one of its proposed application is in double glazed window. With consideration of the parameters of double glazed window using heat transfer equations and mathematics calculations, we could save the thermal energy with appropriate design of parameters such as dimension and thickness of each window and the gas type used between two glazed windows. Simultaneously, by appearing of two different temperatures in two distinct surfaces of the window, we claimed that we could generate electric power using assembling of thermoelectric modules in double glazed window.
