In the previous paper, a new assessment system named CASBEE-HI (Comprehensive Assessment System for Building Environmental Efficiency on Heat Island Relaxation) has been proposed for evaluating the effects of various countermeasures related to building design on heat island relaxation, and the outline of the evaluation sheet of CASBEE-HI was reported. In order to determine weighing of evaluation items in the evaluation sheet of CASBEE-HI, the sensitivity analysis of the influence of each relaxation strategy is necessary. In this paper, the example which performed the trial calculation fo change on the environmental efficiency (BEE_<HI>) of the building on heat island relaxation described in the evaluation sheet by the numerical analysis using three-dimensional CFD and one-dimensional urban canopy model.
