A Simplified calculation method for thermal performance of the windows with frames used in non-residential buildings was proposed in this paper. The major difference of the proposed method from that used in the current PAL (Perimeter Annual load) calculation is that it takes the thermal influence of frames into account. Comparison calculations were undertaken between the conventional PAL calculation (where the influence of frames was neglected) and the proposed PAL calculation (where the influence of frames was taken into account). As a result, it was examined that heating PAL was smaller and cooling PAL was larger by the proposed method. Moreover, in annual PAL, it was confirmed that PAL values changed according to the areas and the specifications of the windows and frames. It was shown that the influence of window frames couldn't be neglected in PAL calculations.
