The integrated design of SWH systems in high-rise buildings for hot-summer and warm-winter climates: Analysis of heat-collecting performanc of the integrated solar system

This paper presents a case study in which solar heat-collecting performance of the integrated solar hot-water system was discussed with numerical simulation. The solar system is integrated into a high-rise residential building. Calculation results show that a combination of solar collectors installed on the roof and wall can produce enough hot water which could meet design requirement. Furthermore, the calculation using annual average data was compared to that using monthly average data. It was found that there is a great difference in the required solar heat-collecting area every month.
