Optimization Analysis of the Residential Window-to-Wall Ratio Based on Numerical Calculation of Energy Consumption in the Hot-Summer and Cold-Winter Zone of China

Along with the rapid urbanization and economic growth of China over past decades, thermal comfort needs people in this region have risen dramatically, at same time, promoting building energy efficiency is cited as part major projects 14th five-year plan for improvement. In addition, outbreak COVID-19 epidemic has plunged into long-term panic, promoted entire construction industry to think about a healthier more sustainable living environment. To respond imbalance between supply demand, an optimization analysis based on use developed, assessing window-to-wall ratio (WWR) design calculating consumption three different types residential buildings both cooling heating loads well year-round loads. Owing its harsh climate huge consumption, study, Hot-summer Cold-winter (HSCW) zone was chosen experimental setting WWR. Then, main buildings, including detached houses, multi-story dwellings high-rise dwellings, correlation WWRS season, season built. The comparisons are presented. recommendation proposed. It significant positive meanings development green sustainably designed that offer high levels efficiency.
