This study is aimed to propose the method of the multiple evaluation of urban block environments using "The Three-dimensional Use Diagram" and "The Sunlight Diagram" and to make clear of efficiency of it, from the view that floors should be situated suitably for its use and should have sunlight condition suitably for its use. First, I make clear of the condition of sunlight about each of the five urban block models analysing "The Sunlight Diagram" based on simulated data. And analysing the ratio of the floor area with the sunshine for four or more hours to the residencial floor area with it, I make clear of the most suitable land-use composition to each models, it is given as a conclusion that the three-dimensional separation of residence and other uses is an effectual method.
