Using a questionnaire survey, microclimate measurements, and onsite observations, this study analyzed the combined influence of meteorological factors, human public space use on OTC in cold winter-hot summer climate Beijing, China. The results indicated significant seasonal difference between winter summer. neutral PET range were significantly higher than winter. Among all globe temperature primarily impacted during two seasons. Relative humidity was more influential air velocity In addition to temperature, only factor that affected cooling is important insulation; however, wind protection prioritized over ventilation. Some such as age, activity intensity, visiting purpose, short-term thermal history, environmental stimuli, also affect support existence adaptation. Moreover, found substantial discrepancies temporal distribution age attendees different types spaces This discrepancy has considerable impact OTC. Finally, several urban design strategies for optimization are proposed.

This study investigates the relationship between urban block spatial morphology and microclimate in severe cold regions, using Shenyang, China as a case study. We employed computational fluid dynamics theory-based numerical simulation software controlled variable approach to analyze effects of four key aspects: street conforming line ratio, interface density, aspect building roof forms. The primary findings are follows: Decreasing ratios initially increase average wind speed temperature. Lower densities reduce but raise Higher correspond increased decreased Additionally, upward sloping roofs correlate with higher research provides perspective for evaluating microclimates, considering human perception space. It also suggests layout design strategies different types streets climate environment.

In the context of global warming and frequent occurrence extreme weather, coastal cities are more susceptible to heat island effect localized microclimate problems due significant influence oceanic climate. This study proposes a computer-driven simulation optimization method based on multi-objective algorithm, combined with tools such as Grasshopper, Ladybug, Honeybee Wallacei, provide scientific decision intervals for morphology control evaluation factors at initial stage city block design. The effectiveness this strategy is verified through empirical research typical neighborhoods in Dalian. results show that derived from optimization-based significantly improves wind environment thermal comfort Dalian winter summer: reduced average speed inside by 0.47 m/s increased UTCI 0.48 °C winter, it 1.5 decreased 0.59 summer. shows use assessment technology adjust form can effectively improve seasonal basis design renewal cities.

Naozhou Island is located in a subtropical marine monsoon climate, with frequent windy days throughout the year, which has significant impact on residents’ lives. The spatial form of local traditional villages adapted to wind environment through long-term practical exploration. This study aims quantitatively analyze this layout explore patterns its climate adaptability, thereby providing guidance for modern village construction. research method primarily involves using CFD software (2019) parameters village, namely scale, planar form, building density, and orientation, along their effects average speed, speed amplification factor, field coefficient under normal extreme conditions. results show that an appropriate can enhance adaptability while scale density significantly affect environment. However, orientation does not have changes due discontinuity street system. These assist planning design future coastal regulation disaster resilience island villages.
