The seasonal shading correction factor had been used for calculation of PAL (perimeter annual load). When the energy efficiency standard was revised in 2013, new calculation tool of the seasonal shading correction factor was needed because climate zone is changed and simple tool is required. In this paper, basic logic to calculate the seasonal shading correction factor is shown, and the calculation method is verified. New calculation tool of the seasonal shading correction factor is released in the site of the revised energy efficiency standard for buildings (http://www.kenken.go.jp/becc/).
