A study on integration design of solar hot-water systems in high-rise residential buildings

This paper analyzes surveys of domestic hot-water use in three Chinese cities (Shanghai, Hangzhou, Guilin). The survey results reveal that the ratio of solar hot water in domestic hot-water uses is less than 20%. Use patterns of hot water are different from different seasons and locations. This suggests that the amount of daily hot-water consumption should be determined by local climatic and economic conditions. From successfully-completed construction projects, the integrated design guidelines for high-rise residential buildings are also provided in the paper.
