Indoor of a membrane structure, there is natural brightness through the polyietra fluorine ethylene membrane, However, in winter season it is difficult to keep it in a snow cold area. Then snow removal is necessary for it and in order to security the reduction of snow load should be practiced usually. In this paper, we studied about a control method of real time snow melting operation by using the membrane structure, in Toyoura city of Hokkaido Pref, which is a snowy and cold area in Japan. We obtained the following results. (1)The method of cluster analysis of snowfall data was effective towards the patternization of snowfall. And the characteristics of snowfall in Toyoura were obtained clearly. (2)We analyzed the heat quantities for melting the snow over the top in snowing, and proposed the control method of real time snow melting operation. (3)We applied control by using Neural Network system, and showed it was usefulto real time snow melting operation.
