In recent years, many buildings have set up eaves on an outer wall surface in order to control solar radiation. In case of snowy regions, eaves on building may be covered with snow. Consequently, the risk of falling snow and ice from eaves should be considered in such cases. The authors have started experimental studies of snow conditions accumulated on louvered eaves of a building. In the first, the laboratory experiment using artificial snow was curried out for clarifying the effect of member composing the eaves. Then, field experiments were performed to compare the accumulation of snow and its change in the three regions with different weather conditions.
