NUMERICAL ANALYSIS OF THE SOLAR SHADING EFFECTS OF PREMISES FORESTS AT DISPERSED HOUSES IN TONAMI PLAIN USING THERMAL SIMULATION

This paper analyzed the solar shading effects of premises forests at dispersed houses in Tonami on a summer sunny day using the 3D CAD-based environment simulator. First, six types of premises forest with different features were selected as analysis objects from previous research and field survey results. The diurnal surface temperature variations at these dispersed houses were simulated and the following indexes were estimated: the MRT distribution at 1.5 m height in outdoor living spaces; HIP (an index to express the sensible heat flax from all external surfaces). The solar shading effects were quantified by simulated values of these indexes.
