Dynamic Integration of Shading and Ventilation: Novel Quantitative Insights into Building Performance Optimization

Buildings, Год журнала: 2025, Номер 15(7), С. 1123 - 1123

Опубликована: Март 30, 2025

Buildings consume nearly 40% of global energy, necessitating innovative strategies to balance energy efficiency and occupant comfort. While shading ventilation are critical sustainable design, they often studied independently, leaving gaps in understanding their combined potential. This study provides a novel quantitative analysis dynamic strategies, using dataset 5000 simulations IDA Indoor Climate Energy (IDA ICE) reveal the synergies trade-offs building performance. Four distinct scenarios analyzed: minimal limited (shading factor Sf = 0.0, ACH 0.5), optimized moderate (Sf 0.5, 1.5), enhanced dynamically adjusted, 2.5), high with maximum 1.0, 3.0). The results show progressive reduction thermal discomfort, predicted percentage dissatisfied (PPD) decreasing from >80% first scenario ~25% ~15% scenario. demand increases by up highest scenario, highlighting trade-offs. These findings underscore importance integrating ventilation, providing actionable recommendations such as night cooling that can reduce discomfort improve 30%. By bridging research gaps, this advances design offers robust framework for creating energy-efficient, comfortable buildings.

Опубликована: Апрель 18, 2025

Although the immediate impact of COVID-19 pandemic has been alleviated, its long-term effects continue to shape global health and public safety. Policymakers should prepare for potential future crises direct urban planning toward more sustainable outcomes. While numerous studies have examined factors influencing risk COVID-19, few investigated spatial spillover form green space. In this study, we quantified using landscape pattern indices, represented population mobility with Baidu Migration Scale Index, assessed role key on epidemic through STIRPAT Durbin models. Our findings reveal that migration from Wuhan had a significant local spread COVID-19. These not only intensified transmission, but also triggered positive effects, spreading virus neighboring regions. We found space connectivity (pc5) plays crucial in reducing virus, both locally surrounding areas. High helps mitigate disease transmission during an epidemic. contrast, configuration unipolarity areas (pc1) contributed increased cities. Ultimately, balancing building density distribution is essential enhancing resilience. This research provides new insights into us understand gray–green forms
