A numerical model that deals with 3-dimenational radiative thermal exchanges within an arbitary block area in typical urban situation including surrounding buildings and roads, was established in order to identify the influence of reflection from surroundings on a building's Solar Heat Gain. A systematic numerical experiment that stands on the proposed model did lead several practical results. As one of the most admirable results, a set of the Tables for Factorial Effects by the Theory of Design of Experiment was obtained, in which parameters relating to urban and architectural designs were picked up plausibly and rationally. These deemed to be appropriate to draw following conclusions, - Calmative solar radiation into a window during a day decreases, if the building's W/H becomes small, or if you concem on the lower stories of the building. And due to the multi-iterative reflection within the building canopy, the large reflectance of walls or roads means the increase of Solar Heat Gain immediately. - When you concem on only the peak Solar Heat Gain of south oriented walls during summer, the influence coming from surroundings can be negligible. However, when you look at the peak Solar Heat Gain of east walls before noon or west walls aftemoon during summer, it becomes significant. The peak can be cut down 20 to 70% of which reduction relies on the height of a room considered or W/H of the building.
